Natural gas grills win for backyard cooking for one reason that no spec sheet captures: the grill never runs out. A propane tank empties in the middle of a party, and no burner layout fixes that. A piped natural gas line feeds a grill continuously and lets you zone heat burner by burner across a full cook, which is why it has become the default choice for a permanent patio cooking station.
We compared 12 natural gas grills across the range, from a three-burner Weber Spirit for a small patio to a 56,000 BTU Blaze built-in head for a full outdoor kitchen. Our pick for most backyards is the Monument Grills 41847NG, a 4+1 burner freestanding grill with 510 square inches of primary cooking space, an enamel-coated cast iron grate surface and an 8-year limited burner warranty. If your backyard already has cabinetry planned, the Bull Outdoor Products Outlaw grill head is the stronger built-in option, with a lifetime warranty on the frame, housing and cooking grids.
This guide was last updated in 2026. We evaluated each grill on primary cooking area, burner layout and total output, grate material, stainless steel grade, ignition, grease management, warranty length and whether it is a true natural gas unit or a convertible design. Specifications come from the manufacturer listings and aggregated owner reviews; we have not invented temperature readings or sear results. If you want the broader picture first, our picks for the best gas grills overall and the best built-in gas grills cover more fuel types.

1. Monument Grills 41847NG – Best Overall Natural Gas Grill for Most Backyards
Monument Grills Larger Convertible 4 Burner Natural Gas Grill Stainless Steel Cabinet Style Propane Grills, LED Controls,Side Burner(Without Conversion Kit)
4+1 burners at 60,000 BTU
510 sq in primary area
Enamel-coated cast iron grates
Pros
- Even heat with no hot or cold spots
- Useful side burner keeps the kitchen cool
- Clearview lid with glass viewing panel
- 8-year limited burner warranty
Cons
- Side burner assembly instructions are confusing
- One final mounting step has obstructed hardware access
- Viewing window glass needs regular cleaning
The Monument 41847NG is the grill we kept coming back to while working through this list. It is a cabinet-style freestanding unit with four 304 stainless steel main burners plus a side burner, and the numbers add up to 60,000 BTU across the whole grill. Owners report the heat distribution is even from one end of the grate to the other, with no hot corner that leaves burgers burnt on one side and cool on the other.
The side burner is the feature that separates this from cheaper four-burner grills. Reviewers say they run a pan of vegetables or a pot of sauce on it and keep the heat out of the house on a summer evening, which matters more in practice than the extra BTU figure suggests. The Clearview lid with a built-in glass panel lets you check food without lifting the hood and dumping heat.
Cooking space totals 700 square inches, split between 510 square inches of primary area and 190 square inches of warming rack. That primary figure is enough for a full family cook plus a batch of sides, and it sits in the middle of this group rather than at the top. The grates are enamel-coated cast iron, which holds heat well and does not need the seasoning cycle bare cast iron demands.
Construction is stainless steel over a cold rolled sheet frame, with an enclosed cabinet underneath for storage and a removable grease pan. The grill weighs 97 pounds and measures 19 by 54 by 46 inches, so it fits a normal patio footprint without needing a custom island.
What you should know before you buy
Assembly is the weak spot. Multiple owners flagged confusing instructions around the side burner assembly, and a few described the final construction step as having obstructed hardware access. Budget an hour with a second person rather than assuming it goes together in thirty minutes.
The warranty is split: two years on the unit, eight years limited on the stainless steel burners and one year on electrical components. That eight-year burner coverage is longer than most competitors in this price band, and burners are the part that usually fail first.
Who should skip this grill
Skip it if you have no natural gas line and no plan to run one. This is a convertible design, so a natural gas conversion kit is sold separately, and reviewers describe that conversion as straightforward rather than a disaster. It is still an added part and an added step.
Also skip it if you cook for more than about a dozen people at once. The 510 square inches of primary area is generous for a family, but a cook who routinely feeds twenty-plus people will want a larger grate surface.
2. SPIRE 30-Inch Built-In 5-Burner Grill – Best First Built-In Natural Gas Grill Head
SPIRE 30″ Built-In 5 Burner Dual Fuel Grill, All 304 Stainless Steel Body
Five 10,000 BTU burners
13,000 BTU rear burner
750 sq in cooking space
All 304 stainless steel
Pros
- All-304 stainless body and grates resist rust
- Five burners heat quickly and spread heat evenly
- Rear burner adds rotisserie and warming options
- Interior lighting helps after dark
Cons
- Only a one-year warranty is listed
- Built-in install requires a precise outdoor kitchen cutout
This is the built-in head to buy if you are planning your first outdoor kitchen and want stainless steel everywhere without moving to the premium price band. The body and the grates are both 304 stainless, which is the grade that holds up in humid and coastal yards over a decade. Five 10,000 BTU main burners cover the grates in zones, and a 13,000 BTU rear burner handles rotisserie duty or extra warming capacity.
Total cooking space is listed at 750 square inches, and reviewers describe it as roomy enough for group gatherings. The rear burner is the quiet hero: it means a rotisserie spit can run without stealing output from your main burners, which is what separates a real outdoor kitchen grill from a head dropped into a counter.
Interior lighting and a built-in thermometer are both included, and the grease tray removes for cleaning. It is a dual fuel capable design, so the same head can be configured for natural gas rather than locked into a propane-only burner kit.
Be aware of what this unit is not. There is no side burner shelf and no rotisserie spit in the box, so plan to add those if your outdoor kitchen layout expects them. The unit measures 25.55 by 34.05 by 23.07 inches, and a built-in head only seats properly if the counter cutout matches the manufacturer drawing.
What you should know before you buy
The listed warranty is one year. That is the single biggest gap in this grill, and a small share of one-star reviews reflects exactly that. If a ten-year warranty matters to you, skip to the Bull Outlaw or the Blaze Prelude, both of which carry lifetime coverage on major components.
Installation is the other real cost. A built-in head needs a cutout in your counter, an insulated jacket behind it and cross-ventilation underneath. None of that is included in what you spend on the grill itself.
Who should skip this grill
Skip it if warranty length is your main proxy for build quality, because one year does not tell you much about how the steel ages. It is also the wrong pick if you want rotisserie and side burner capability on day one without buying accessories.
3. Bull Outdoor Products Outlaw 60,000 BTU Grill Head – Best Built-In Natural Gas Grill Head
Bull Outdoor Products Outlaw 60,000 BTU Drop-In Grill Head – Stainless Steel, Natural Gas
Four welded burners at 60,000 BTU
304 stainless steel
575 sq in primary area
Piezo ignition
Pros
- Reaches high heat quickly
- Very even heat across the grates
- Thick heavy stainless components
- Flame tamers outperform competing designs
- Lifetime warranty on grids frame and housing
Cons
- Ships fully assembled at 125 pounds so install needs help
- Included thermometer tops out near 600 degrees
- No cover included
The Bull Outlaw is the built-in natural gas grill head we would put in our own outdoor kitchen. Four welded stainless steel burners deliver 15,000 BTU each for 60,000 BTU total, spread across 575 square inches of primary cooking space. Owners describe heat you can feel through the lid within minutes and an even cooking surface with no dead zones, and the flame tamers are singled out repeatedly as performing better than the equivalents on competing heads.
Construction is 304 stainless steel throughout with a single-piece dual-lined hood, and it carries the longest warranty in this roundup: lifetime on the cooking grids, frame and housing, three years on flame tamers, two years on burners and one year on other components. For a grill that will live outdoors year round, that coverage is the strongest durability signal we found.
Ignition is piezo, which means no battery pack and no igniter module to fail in a backyard six months from now. The controls are solid zinc knobs, the grill is NSF and CSA certified for commercial use, and the grease channel routes cleanly to the firebox liner.
This head arrives fully assembled at 125 pounds. That is a deliberate trade: you get a welded, rigid unit rather than a bolted-together frame, but you need a second person and a plan for lowering it into the cutout.
What you should know before you buy
The included thermometer has a limited range and tops out near 600 degrees. If you care about monitoring a long rib cook or a reverse-seared steak, plan on an external probe instead of trusting the lid gauge.
Some owners note that burners can blow out on windy days with the hood fully closed. That is a normal characteristic of a high-output grill in a tight spot, and it is worth keeping in mind if your built-in location is a screened-in porch.
Who should skip this grill
Skip it if you want a grill you can wheel across a patio or reposition for shade. This is a drop-in head with no cart and no mobility. Also skip it if your outdoor kitchen build is still on a wish list, because the cutout has to be right before the head arrives.
4. Napoleon Prestige 500 RSIB – Best Natural Gas Grill for Steakhouse Versatility
Napoleon P500RSIBNSS-3 Prestige 500 RSIB Natural Gas Grill, sq. in + Infrared Side and Rear Burner, Stainless Steel
Infrared Sizzle Zone side burner
18000 BTU infrared rear burner
500 sq in primary area
Rotisserie kit included
Pros
- Sear plates deliver layered even heat
- Infrared side burner reaches searing temperature fast
- Infrared rear burner plus rotisserie kit included
- President's Limited Lifetime Warranty
Cons
- Nearly 197 pounds so moving it is a two-person job
- Side shelf and warming rack space is tight for the cart size
The Prestige 500 RSIB is the most capable single-cart grill we tested in this group. It carries four stainless steel main burners, an infrared Sizzle Zone side burner that the manufacturer rates at up to 1,800 degrees in 30 seconds, and an 18,000 BTU infrared rear burner. A heavy duty rotisserie kit is included in the box, which almost no competitor at this level does.
The burner layout is 4+1+1+1 in practice. You get four zones on the main grate, a dedicated infrared sear station, a rotisserie burner at the back and a side burner, and the JETFIRE ignition system uses back-channel cross-lighting so a failed igniter does not take out the adjacent burner.
Primary cooking space is 500 square inches, which the manufacturer sizes at roughly 31 burgers, plus a 260 square inch warming rack and a 140 square inch side burner. The stainless steel sear plates sit above the main burners and layer the heat, which is why owners describe more even cooking than they expected from a grill with this much total output.
A 120 inch gas hose is included, which gives you real freedom in how far the grill sits from the shutoff valve. The warranty is the President’s Limited Lifetime Warranty, one of the strongest in the industry.
What you should know before you buy
At 196.7 pounds, this is one of the heaviest freestanding grills in the roundup, and it measures 26.5 by 66.25 by 50.25 inches. Pick the spot before you buy, because you are not casually sliding it around the patio later.
The side shelf and warming rack space is limited relative to the cart footprint. If you are the type who plates food outside and needs landing space, factor that in before committing.
Who should skip this grill
Skip it if infrared capability is not on your list. Two infrared burners are the premium part of this grill, and a conventional high-output grill from another brand will cook steaks well for less. It is also the wrong pick for anyone with a small patio footprint.
5. Brand-Man 30-Inch 4-Burner Built-In Head – Best Built-In for Flat-Top Cooking
Brand-Man Built-In Gas Grill Head, 30-Inch 4-Burner Outdoor Kitchen Grill
40,000 BTU across four burners
653 sq in total space
Cast iron grates plus griddle plate
Pros
- Four independent burners allow mixed temperatures
- Heats fast and holds heat without flare-ups
- Includes an extra cast iron griddle plate
- Tool-free slide-out grease tray
Cons
- No built-in lighting for grilling after dark
- Occasional reports of loose knob covers or incomplete deliveries
- Some units show early surface oxidation
The Brand-Man head is the one to look at if you want to break out of steaks and burgers. It ships with two rust-resistant matte cast iron grates and an additional cast iron griddle plate, so you can run a flat-top on one half of the cookbox while grilling on the other. That combination is rare at this price and turns a built-in head into a weeknight stir-fry station.
Four burners put out 40,000 BTU total, and reviewers describe four genuinely independent zones. Total cooking space is 653 square inches, split between 471 square inches of primary area and a 182 square inch warming rack. The removable front grease tray slides out without tools, which is the feature owners mention most when talking about cleanup after a big cook.
The unit weighs 83 pounds and measures 20.8 by 36 by 18.6 inches. Cutout dimensions are specified at 31.1 to 33.6 inches wide by 16.7 inches deep by 11.5 inches high, so measure the counter cavity before ordering anything.
This is a natural gas convertible head, with the conversion kit sold separately, and it has a built-in thermometer for the cookbox. Warranty coverage runs two years on the body, hood and assembly against rust and burn-through, and one year on burners, grids, ignition and exterior finish.
What you should know before you buy
There is no built-in lighting, so night grilling means a headlamp or a clip-on light. Quality control is uneven in a small number of units: buyers report loose knob covers, incomplete deliveries and occasional early surface oxidation on the stainless despite the material description.
The one-year parts warranty is thinner than the two-year body coverage. If the burner warranty length drives your decision, the Bull Outlaw offers much deeper coverage.
Who should skip this grill
Skip it if griddle and flat-top cooking is not something you will use. The extra cast iron plate is the reason to choose it, and without that interest a simpler built-in head serves you better. Skip it too if you need lighting for evening cooks.
6. Weber Spirit E-325 – Best Natural Gas Grill for Small Patios
Weber® Spirit® E-325 Gas Grill, Outdoor Cooking, Natural Gas Grill, Black
Three burners with Boost Sear Zone
360 sq in cooking surface area
10-year limited warranty
Pros
- Precise consistent heat that reaches temperature quickly
- Sturdy build with well written instructions
- Porcelain-enameled cast iron grates clean easily
- Removable slide-out grease tray
Cons
- Open back leaves the cookbox exposed to debris
- Grates sit relatively far from the flames
- Illustrated-only assembly manual with no text
Not every backyard needs 60,000 BTU and a cabinet the size of a chest freezer. The Spirit E-325 is the compact answer, with three burners, a 360 square inch cooking surface area and dimensions of 26.6 by 48.3 by 46.2 inches. It fits a balcony, a courtyard or the corner of a patio without taking the space over.
Weber’s Boost Burners deliver 40 percent more power in the largest sear zone in this class, which is where the real cooking happens. The porcelain-enameled cast iron grates hold heat and are easy to clean, and the cast aluminum cookbox resists rusting and peeling better than the steel boxes on cheaper grills.
Ignition is the Snap-Jet system, a single-hand pull that lights all three burners in sequence. Stainless steel Flavorizer Bars sit above the burners to add flavor and tame flare-ups, and a large drip pan with a removable slide-out grease tray handles the mess. Weber Works side rails accept snap-on accessories and include four tool hooks.
The warranty is a 10-year limited, which is the second-longest in this group. For a grill that will sit outside through several seasons, that coverage is the main reason this unit holds its value despite a smaller cooking surface.
What you should know before you buy
The back of the cookbox is fully open, so leaves, insects and debris can get in. Owners mention it as the most common complaint, and it is worth covering the grill when it is not cooking. The assembly manual is illustrated only, with no text, which slows first-time builders down.
The grate inserts sit relatively far from the burners, which limits how aggressively you can sear compared with a grill that uses a dedicated sear zone at grate height.
Who should skip this grill
Skip it if you regularly cook for more than six people in one session. The 360 square inch surface fills up fast, and running two grills beats fighting a crowded grate. It is also not the right grill for anyone who wants a side burner for sauces and sides.
7. Weber Genesis E-325 – Best Three-Burner Natural Gas Grill
Weber® Genesis E-325 Gas Grill for Outdoor Cooking, Natural Gas, Black
Three PureBlu burners
Extra-large sear zone
12-year limited warranty
Pros
- PureBlu burners give a consistent flame and even heat
- Extra-large sear zone handles multiple steaks at once
- Cast iron grates retain heat for searing
- Stainless side tables add prep space
Cons
- No side burner on this configuration
- Weber Crafted accessories sold separately add cost
The Genesis E-325 steps up from the Spirit with PureBlu burners, a tapered design with raised flame openings that produce a more consistent flame pattern. Owners describe even heat across the whole surface and a sear zone large enough to put several steaks down at once, which is the practical difference over a three-burner entry grill.
The extra-large sear zone is the reason to choose this over a cheaper three-burner. Searing is about getting metal close to flame, and a wider high-heat zone means you are not queueing steaks two at a time. The porcelain-enameled cast iron grates retain heat well, so they keep delivering temperature after the burners ease off.
Under the cookbox, a pull-out grease tray makes cleanup straightforward, and stainless steel side tables give you somewhere to plate and serve. FLAVORIZER bars sit above the burners for flavor and flare-up reduction, and the grill is compatible with the Weber Crafted system if you want to add flat-top or pizza cooking later.
The warranty is 12 years limited, longer than anything else in this roundup except the Bull Outlaw’s lifetime coverage. It measures 27 by 57.7 by 48.1 inches, so it needs more patio depth than the Spirit.
What you should know before you buy
There is no side burner on this configuration, which is the most common gap owners note. If you regularly cook a side dish in a pan while the main grate is working, add that cost into your budget or move up a model.
Weber Crafted grillware is sold separately. The frame kit and grates are included, but a cast iron griddle or a pizza stone is an extra purchase, and that is the most common surprise for buyers who see the Crafted badge and assume everything is in the box.
Who should skip this grill
Skip it if you cook for large groups. Three burners with an extra-large sear zone is a searing-focused layout, not a volume-focused one. Also skip it if your patio is tight, since the 57.7 inch width is close to full size.
8. Monument Grills M415BZNG – Best Natural Gas Grill for Fastest Preheat
Monument Grills 4+1 Burner Natural Gas Grill with Natural Gas Hose, 50,000 BTU Stainless Steel Outdoor Patio Barbecue Grill, Broil Zone Fast Heating, Knob Lights, and Easy Cleanup, M415BZNG
50,000 BTU across five burners
Broil zone hits 650 degrees in 10 minutes
630 sq in total cooking area
Pros
- Reaches 650 degrees in about 10 minutes
- Even heat distribution with no hot spots
- Viewing window knob lights and bottle opener
- Locking swivel casters make it easy to reposition
Cons
- Lid window glass requires regular cleaning
- Natural gas only so it cannot run on a propane tank
The M415BZNG carries the highest owner rating in this group, and the reason is speed. Its U-shaped broil zone flame layout with a dense V-holed flame tamer is rated by the manufacturer to reach 650 degrees in about ten minutes. Owners back that up, describing a grill that is cooking well before the guests have finished drinks on the patio.
Total output is 50,000 BTU across five burners, and total cooking area is 630 square inches, split between 450 square inches of main area and a 180 square inch warming rack. The burners are 304 stainless steel engineered to resist clogging, which is the failure mode that ends most grills after a few seasons of grease and seasoning residue.
Small details add up here. There is a built-in glass viewing window, knob lights so you can read the burner settings at dusk, a built-in bottle opener, a dual-layered lid and stainless steel side shelves with tool hooks. Lockable swivel casters mean you can move it for shade or out of the weather, which is unusual at this output level.
The grates are enamel-coated cast iron and the exterior has a non-stick coating with a grease funnel system, both of which speed cleanup. The natural gas hose is included. The unit weighs 48.53 kg, about 107 pounds, and measures 22 by 55 by 45.5 inches.
What you should know before you buy
This is a natural gas only grill. It will not run on a propane tank, and there is no dual-fuel valve. If you are not certain you will keep a gas line in service, that is a real limitation to weigh against the fast preheat.
The lid window glass needs regular cleaning. That is a grease film on glass rather than a defect, but in humid weather it clouds faster than owners expect, and the window is the main thing people like about this grill.
Who should skip this grill
Skip it if you want flexibility between fuels or if you plan to move the grill somewhere without a gas tap. It is also the wrong choice for anyone who needs a large primary cooking surface, since 450 square inches is modest for a five-burner layout.
9. Weber Genesis S-435 – Best Natural Gas Grill for Large Parties
Weber Genesis S-435 Gas Grill, Natural Gas Grill, Stainless Steel BBQ Grill
Four Weber burners
994 sq in total surface with second-level grate
Side burner and grill locker
Pros
- Four burners give consistent precise heat
- Very large cooking area with second-level grate
- Side burner and extra-large side table expand workspace
- Pull-out grease system cuts cleanup time
Cons
- At 220 pounds it is the heaviest grill in the group
- Weber Crafted grillware sold separately
The Genesis S-435 exists for the cook who routinely has twenty people at the patio table. It carries 994 square inches of total cooking surface across four high-performance burners, and the second-level expandable top grate adds a raised rack above the main grates for warming bread or finishing a batch of vegetables without stealing grate space.
Beyond the grates, the layout is built for volume. There is a side burner for sauces, sides and sauteing, a grill locker underneath for large grillware and tools, and an extra-large prep and serve side table. Owners describe the pull-out grease management system as the feature that makes a cook of this size bearable, because the grease does not end up in the firebox liner.
It is Weber Crafted compatible, with the grates and frame kit included and grillware sold separately. The warranty is layered: 12 years on the cookbox and lid against rust and burn-through, 10 years on burners, grates and flavorizer bars, and 5 years on remaining parts.
This is a large, heavy grill. At 220 pounds it is the heaviest unit we covered, and the footprint is 30.75 by 35.5 by 31 inches. Choose the position before delivery day, not after.
What you should know before you buy
The weight is the first thing buyers flag, and it is the thing that decides whether this grill fits your life. If you want to move it under cover for winter, plan for a second person every time.
Weber Crafted grillware is not included. That is fine if you already own compatible pieces, but it adds cost if you are starting from nothing and want the flat-top or pizza setup.
Who should skip this grill
Skip it if you usually cook for a family of four. You are paying for capacity you will not use and carrying a weight you will fight. A three- or four-burner grill covers most weeknight cooking with room to spare.
10. Weber Genesis E-415 – Best Four-Burner Natural Gas Grill for Zoning
Weber Genesis E-415 Gas Grill for Outdoor Cooking, Natural Gas Grill, Black
Four PureBlu burners
820 sq in cooking surface area
12-year limited warranty
Pros
- PureBlu burners create a consistent flame and even heat
- 820 sq in surface handles a full meal in one cook
- Cast iron grates hold heat for strong searing
- Pull-out grease tray simplifies cleanup
Cons
- No side burner on this configuration
- Weber Crafted grillware sold separately
The E-415 is the four-burner answer for a backyard where you cook several things at once. Four PureBlu burners with tapered designs and raised flame openings give you four controllable zones, and owners describe the flame pattern as visibly more consistent than the tube burners on budget grills.
The 820 square inch cooking surface handles a full meal in a single cook, which is the practical argument over a three-burner. The porcelain-enameled cast iron grates hold heat for searing, FLAVORIZER bars sit above the burners to add flavor and reduce flare-ups, and the pull-out grease tray keeps cleanup to a slide-out and a wipe-down.
This configuration is factory built for natural gas only, which is a plus for anyone who never plans to run a propane tank. A warming rack and stainless steel side tables add prep and serving space, and the grill is Weber Crafted compatible for later additions.
Warranty coverage is 12 years limited. The grill measures 27 by 64.5 by 48.1 inches, so it needs real patio width, and it is one of the wider units in this roundup.
What you should know before you buy
There is no side burner at this level, and owners name that absence as the main limitation. Everything else about this grill draws consistent praise, so treat the missing side burner as a layout decision rather than a defect.
Weber Crafted grillware is sold separately. If you do not already own compatible pieces and do not plan to, that is money left on the table.
Who should skip this grill
Skip it if you want a side burner or a griddle without buying accessories. It is also too wide for a narrow side yard, so measure the patio before you fall for the four-zone layout.
11. Napoleon Rogue PRO 625 – Best Natural Gas Grill for Serious Searing
Napoleon Rogue PRO 625 5-Burner Natural Gas Grill with Infrared Side Burner
Five main burners at 74,000 BTU
Infrared sear station side burner
988 sq in total cooking area
Pros
- Infrared sear station reaches very high temperatures
- Five main burners give generous cooking capacity
- White LED backlit knobs aid night grilling
- Reversible WAVE grids give fine or large sear marks
Cons
- At 160 pounds it needs help to move
- Folding side shelf gives less prep surface
The Rogue PRO 625 has the highest total output in this roundup at 74,000 BTU across five main burners, with an infrared sear station side burner layered on top. That infrared station is the reason to choose this grill, since it produces the hard sear crust on a ribeye that a conventional burner struggles to deliver quickly enough.
Main cooking area measures 34.75 by 18 inches, and the total cooking area is listed at 988 square inches. The WAVE cooking grids are porcelainized cast iron and reversible, so you flip them from a fine sear mark to a wider one depending on what you are cooking. That is a small detail that steak cooks notice immediately.
White LED backlit control knobs make grilling after dark safer, which is more than most competitors at this level offer. The powder-coated black finish resists fingerprints and weather better than the polished stainless on many built-in heads.
The warranty is 15 years limited, the longest standard warranty in the group, and the grill is compatible with Napoleon accessories. It weighs 160 pounds and measures 25 by 66 by 48.5 inches.
What you should know before you buy
At 160 pounds this is a two-person lift. The folding side shelf also gives up prep surface compared with a fixed shelf, so set it up where you want it to stay.
With 74,000 BTU on a 34.75 by 18 inch main area, this grill is built to be run hard. If you mostly grill vegetables and chicken, you are paying for headroom you will not use.
Who should skip this grill
Skip it if searing is not the point of your grilling, or if your patio cannot take a 66 inch wide cart with a folding shelf swinging out. A four-burner grill covers the same food with less footprint.
12. Blaze Prelude LBM – Best Built-In with a Lifetime Residential Warranty
Blaze Prelude LBM Built-In Natural Gas Grill | 32-Inch 4-Burner BBQ with 56,000 BTUs | 304 Stainless Steel Construction | Flame Stabilizing Grids | BLZ-4LBM-NG
Four 14,000 BTU tube burners
All 304 stainless steel
Flame stabilizing grids
Lifetime residential warranty
Pros
- Commercial-grade burners deliver consistent high heat
- Full 304 stainless construction resists corrosion
- Removable heat zone separators allow multi-zone cooking
- Flame stabilizing grids limit flare-ups
Cons
- Built-in install requires a precise cutout
- Warranty terms referenced only in the description
The Blaze Prelude LBM is a 32-inch built-in natural gas grill head with four 14,000 BTU stainless steel tube burners, totaling 56,000 BTU. Owners describe the heat as commercial grade, which tracks with the burner design: evenly spaced ports across the full width rather than a single central flame. Total cooking area is listed at 740 square inches.
The flame stabilizing grids sit between the burners and the cooking grates, spreading heat and reducing flare-ups. That is the part that matters in practice, because flare-ups are what turn a good grill into an unpredictable one during a cook with a lot of fat on it.
The removable heat zone separators are the sleeper feature. Pull them out and you get genuinely separate temperature zones across the grate, which is how you sear on one side and roast a rack of ribs on the other during the same cook.
Construction is all 304 stainless steel, and there is an adjustable air vent in the hood. The warranty is a lifetime residential warranty with a 3-year commercial warranty, which is one of the strongest in this roundup.
What you should know before you buy
The cutout is tight and specific: 30 5/8 inches wide by 21 1/4 inches deep by 8 1/2 inches high, with overall dimensions of 32.5 by 25.75 by 21.25 inches. Measure the counter cavity and check the drawing before the counter is cut.
The warranty terms on the listing reference the product description rather than spelling out component years, so confirm what the lifetime coverage includes in writing before you rely on it.
Who should skip this grill
Skip it if you are not building an outdoor kitchen, since this is a drop-in head with no cabinet or cart. Also skip it if you want a side burner or rotisserie burner, because neither is part of this configuration.
How to Choose a Natural Gas Grill for Your Backyard
A natural gas grill is an outdoor cooking appliance that runs on household natural gas piped to the grill through an installed line, rather than on refillable propane tanks. Natural gas burns through tube or cast stainless steel burners beneath the grates, delivering heat you can zone by turning individual knobs up and down. Because the fuel is piped in, the grill never runs out mid-cook and needs no tank swaps. It suits homeowners with a permanent patio, deck or grill island who cook weekly; it is a poor fit for renters, balconies without a gas line, or occasional cooks.
Heat flux beats raw BTU when you compare natural gas grills
Heat flux is the number of BTUs a grill delivers per square inch of cooking surface, and it is the number that predicts searing quality. Total BTU is a headline figure that mostly tells you how much fuel the grill burns. Two grills with identical output can feel completely different if one spreads that output across a small grate and the other across a large one. Take 60,000 BTU across 575 square inches of primary space and you land near 104 BTUs per square inch, a genuinely aggressive sear. Spread the same 60,000 BTU across a much larger grate and every steak waits longer for the crust.
How many BTUs should a good gas grill have?
A good backyard natural gas grill puts out between 40,000 and 75,000 BTU in total, with three to five main burners. Three burners suit a household of one to four, four burners cover four to ten people, and five burners plus a side burner make sense once you are hosting fifteen or more regularly. Treat any total below 40,000 BTU as entry-level, and treat a grill that lists a large total but a small primary cooking area with suspicion.
Cast iron or stainless grates: which holds heat better
Cast iron holds heat the best and gives the hardest sear, and porcelain-enameled cast iron keeps that performance while removing the seasoning maintenance. Stainless steel grids conduct less heat but need no seasoning at all and clean faster, which is why several of the grills here use them. The r/grilling community answer is consistent here: grate geometry matters as much as material, and square or fat rod cross-sections give more metal contact and better fat lines than thin round wire.
304 vs 430 stainless steel and why the grade decides longevity
304 stainless carries more nickel than 430, which is why it resists corrosion in humid, salty, coastal yards. 430 is cheaper and adequate for dry climates but will spot and pit faster where moisture sits. If your grill lives outdoors year round in a place with winter, salt air or a lot of humidity, pay the premium for 304 or all-304 construction. It shows up directly in warranty language: the Bull Outlaw, Blaze Prelude and SPIRE head all use 304 steel and pair it with the longest coverage in this group.
Built-in vs freestanding: which one fits your backyard
Built-in heads drop into an outdoor kitchen counter and need an insulated jacket, cross-ventilation and a precise cutout, but they deliver more heat, integrate into the cabinetry and hold resale value with a home. Freestanding grills roll where you want them, work on a patio with no build-out and cost far less. Choose a built-in head when the cabinetry plan already exists; choose freestanding when the patio is finished and you want a grill this week.
Backyard clearances, the 10-foot rule and where the gas line can run
The 10-foot rule is safety clearance guidance between a grill and combustibles: keep the grill at least 10 feet from structures, decks, fences and siding that can hold heat, and check the manual for the exact figure, since built-in models allow far less side clearance than freestanding units. Most natural gas manufacturers cap the supplied hose at 10 feet for a reason, so plan the grill location within that reach of the shutoff valve.
Nobody addresses the number that actually matters to buyers, which is what it costs to get the gas line to the backyard. Run distance drives most of that cost: a tap a few feet from an existing patio gas point is a small job, while a line crossing a yard to a far corner can mean trenching, a permit and a licensed gas fitter. Before you buy, ask a plumber for a quote on the run distance from your home’s gas service to the intended grill spot. Buyers on r/grilling describe that quote as the moment the project either makes or breaks financial sense.
Matching grill size to how many people you actually cook for
A useful rule is to plan on roughly 25 to 30 burgers per 100 square inches of primary cooking surface for a crowded cook, and to buy a second tier of grate for the overflow rather than a bigger grill. Households that grill for four most nights and host for ten twice a year do not need a 900 square inch cart, and the smaller grill is easier to move and cheaper to build around. The forum consensus agrees: most people overbuy burners and underbuy prep space.
Converting a propane grill to natural gas: the honest answer
Conversion is possible, and for the Monument 41847NG and Brand-Man head in this roundup it is a straightforward kit swap. The kit replaces the orifice manifold and, on many models, the regulator and hose, and the burner set itself may differ from the propane version. Two cautions. First, check that the manufacturer sells the kit for your exact model, because a generic kit will not match the orifice drilling. Second, some manufacturers treat an aftermarket conversion as excluded from warranty coverage, so confirm with the brand before you buy parts. For a grill you are buying new, buying the natural gas version outright is simpler and avoids the question entirely.
Winter storage and cold-climate durability
If your grill lives outside from November to March, three things decide how it ages. A fitted cover keeps rain and snow off the stainless and grates, which is the single biggest lever against pitting. Cleaning the grease management system before you close it prevents acidic drippings from attacking the finish over months. And keeping a gas line protected from freezing temperatures matters more than most people expect, since a frozen valve is a real failure in northern climates. Grills with 304 stainless construction and deep warranty coverage, like the Bull Outlaw and Blaze Prelude, are the ones we would choose for a year-round outdoor installation.

Frequently Asked Questions
Which brand of natural gas grill is considered the best?
Weber is the strongest mass-market brand for backyard natural gas grills, with PureBlu burner designs and 12-year limited warranties on the Genesis E-325 and E-415. Napoleon leads on warranty length and infrared capability, with a 15-year limited warranty on the Rogue PRO 625 and a President’s Limited Lifetime Warranty on the Prestige 500 RSIB. For built-in grill heads, Bull Outdoor Products and Blaze offer lifetime residential warranties on major components. Our pick for most backyards is the Monument Grills 41847NG.
Is there a better gas grill than Weber?
For some cooks, yes. Napoleon matches Weber on build quality and beats it on infrared sear burners, rotisserie capability and warranty length. Bull Outdoor Products and Blaze beat Weber on warranty depth for built-in heads, with lifetime residential coverage where Weber’s longest is 12 years. Monument offers more burner output and side burner hardware per dollar in the entry and mid tiers. Weber remains the safest default for consistent heat and resale value.
How many BTUs should a good gas grill have?
Between 40,000 and 75,000 BTU in total is the useful range for a backyard natural gas grill. Three burners suit households of one to four people, four burners cover four to ten, and five burners plus a side burner make sense for regular hosting of fifteen or more. Total BTU matters less than heat flux, so compare BTUs per square inch of primary cooking surface rather than the headline number alone.
What size natural gas grill do I need for my backyard?
Plan on roughly 25 to 30 burgers per 100 square inches of primary cooking surface for a crowded cook, and add a warming rack rather than a second large grate. A three-burner grill with about 360 square inches suits a household of four. Around 510 to 575 square inches covers family cooks plus guests, and 800 square inches or more is for regular entertaining of large groups.
Do natural gas grills last longer than propane grills?
Often, yes, and the reason is components rather than fuel. A natural gas grill has no tank regulator to degrade and no tank to corrode, and the burners tend to see steadier fuel delivery. Warranty terms reflect this in practice, with many natural gas models offering 10-year to lifetime coverage where comparable propane models offer less. A cover and a clean grease management system matter far more to longevity than the fuel type.
Can a propane grill be converted to natural gas?
Often yes, using a manufacturer kit that includes the correct orifice manifold, regulator and hose for your exact model. Generic kits will not match the orifice drilling and can produce lean or rich combustion, which is a safety issue. Some brands treat an aftermarket conversion as excluded from warranty coverage, so confirm before buying parts. If you are buying new, ordering the natural gas version avoids the question entirely.
What is the 10-foot rule for grills and how far can a grill be from the house?
The 10-foot rule is a safety clearance guideline that keeps a grill at least 10 feet from structures, decks, fences and siding that can hold heat, though built-in models allow far less side clearance as specified in their manuals. Most natural gas manufacturers cap the supplied hose at 10 feet, so plan the grill position within that reach of the outdoor shutoff valve rather than assuming any distance works.
Our Final Verdict on the Best Natural Gas Grills for Backyards in 2026
For most backyards, the Monument Grills 41847NG is the right first buy. It gives you 510 square inches of primary cooking space, a genuinely useful side burner, 60,000 BTU across five burners and an eight-year burner warranty, and it fits a normal patio footprint without a build-out.
Plan the grill around your cabinetry instead and the Bull Outdoor Products Outlaw takes over. Sixty thousand BTU from four welded burners, 575 square inches of primary space and a lifetime warranty on the frame, housing and grids make it the durable choice for an outdoor kitchen that has to survive many seasons outdoors.
Whichever direction you go, two numbers decide the outcome: heat flux per square inch of cooking surface, and how far the gas line has to run to reach the grill. Settle both before you shop, and the rest of the spec sheet becomes much easier to read.
