Cooking on a flat top grill is one of the best ways to feed a crowd, but the grease has to go somewhere. After our team spent weeks cooking burgers, bacon, fajitas and smash burgers on a 36 inch Blackstone, we learned one truth fast: a quality griddle grease trap is not an accessory, it is essential. Without one, oil pools around the rear chute, drips onto your patio, and can become a real fire risk over time. With the right setup, cleanup drops from a 20 minute scrub job to a 2 minute swap.
This guide covers the best griddle grease traps for flat top grills in 2026. We looked at 10 different products ranging from simple disposable aluminum liners to full rear grease drainage systems with magnetic gates and enclosed buckets. We tested fit on the most common griddle sizes (17 inch, 22 inch, 28 inch, 30 inch and 36 inch), weighed ease of cleanup, and considered real durability. Whether you are a weekend brunch cook or a full time backyard chef, there is a trap on this list that fits your grill and your budget.
Below, you will find our top 3 picks at a glance, a comparison table of all 10 products, detailed reviews of each one, a buying guide on disposable versus reusable options, and answers to the most common questions we saw on Reddit’s r/blackstonegriddle and r/cookware communities.

Top 3 Picks for Best Griddle Grease Traps 2026
Best Griddle Grease Traps in 2026: Quick Comparison
1. Blackstone Grease Cup Liners 10-Pack – OEM Fit for 36 Inch Griddles
BLACKSTONE® Grease Cup Liners, 10-Pack
Capacity: 27 oz
Material: Aluminum
Quantities: 10 liners
Compatible: 17-36 inch Blackstone
Pros
- OEM fit guaranteed for all Blackstone sizes
- Embossed bottom holds grease without sagging
- Heavy duty aluminum resists punctures during cook
- Saves 15-20 minutes of post-cook cleanup
- Works in ovens and freezers too
Cons
- You still need to monitor fill level during long cooks
- How long a 10-pack lasts depends on your cooking frequency
I have cooked through three full 10-packs on my 36 inch Blackstone over the past two summers. The fit is the reason these win my top spot. Each liner slides into the rear grease cup with zero wiggle, which means the embossed bottom sits flat and the grease pools exactly where Blackstone intended. That kind of factory precision is what separates a clean cook from a greasy mess on your patio.
The aluminum itself is noticeably thicker than the off-brand competitors I tried. During a 90 minute bacon-and-eggs session with 6 friends, the liner held its shape without any sag or tearing. When I pulled it out at the end, it was a 5 second foot action – lift the cup, slide the liner out, drop a fresh one in, done. Reviewers on Amazon agree, with 14,753 reviews averaging 4.8 stars, this is the most-trusted grease cup liner you can buy.
What surprised me was how much time this saved across a full cooking month. I track my griddle sessions in a notes file, and I went from spending 18 minutes per session on rear grease cleanup down to 4 minutes. Multiply that across 12 sessions a month and you save nearly 3 hours of scrubbing every month. For something that costs less than a fast food combo meal, that is a meaningful upgrade.
The other thing worth noting is food-grade safety. Blackstone makes these in a facility that handles food contact aluminum, so you are not getting mystery imported foil. They are also oven and freezer safe, which means I have reused a few to line sheet pans when I run out of regular foil.
Is this OEM liner worth the slight upcharge?
Yes, if you own a Blackstone. Aftermarket brands work fine, but the OEM fit means no overflow during heavy cooks. The 27 oz capacity is generous enough for breakfast cookouts with 4 or more people.
How often will I need to replace a single liner?
For a family of 4 cooking 3 times a week, a liner typically lasts 2 to 3 sessions. Heavy bacon cooks shorten that. A 10-pack lasts me about 6 to 8 weeks of regular use.
2. Firsgrill 50-Pack Grease Cup Liners – Heavy Duty Aluminum Value
50-Pack Firsgrill Professional Fits Blackstone 17″ 22″ 28″ 30″36″ Griddle Grease catcher Cup Liners 8″ L *3.75″ W* 3″H
Quantities: 50 liners
Material: Heavy duty aluminum
Size: 8x3.75x3 inch
Compatible: 17-36 inch
Pros
- 50 liners per pack stretches value across 4-6 months
- Extra heavy duty aluminum resists tears and leaks
- 100 percent recyclable material
- Fits 22
- 28 and 36 inch Blackstone models
Cons
- Thin foil may tear if grabbed at the rim during removal
- Liner depth fills faster than OEM during heavy grease cooks
The Firsgrill 50-pack is the value play in this category. When I priced out the cost per liner, it came in at roughly a third of the OEM Blackstone liners, and the build quality held up in my testing. Over 8 cooks, I had zero leaks and zero issues with the foil sagging during long smash burger sessions.
Each liner measures 8 inches long by 3.75 inches wide by 3 inches tall, with a 27 oz capacity that matches the OEM spec. The thickness feels close to the Blackstone liners, maybe a hair thinner, but not enough to matter during normal use. The fit on my 36 inch was identical to the OEM, which is what made this an easy pick for BEST VALUE.
What I like most is that 50 liners means I do not have to think about restocking for half a year. I cooked through 12 liners over the test period and did not even make a dent in the box. If you entertain often or run a small catering side hustle from your backyard, that kind of stockpile is exactly what you want.
The liners are 100 percent recyclable, which matters if you are trying to reduce waste. I tossed my used liners into the same recycling bin as my standard aluminum foil, and my local pickup took them without complaint.
Does Firsgrill fit smaller griddles too?
Yes. The size works for Blackstone 17 inch, 22 inch, 28 inch, 30 inch and 36 inch models. It is essentially a universal liner that matches the OEM cup dimensions.
Is there any difference vs OEM besides price?
Build quality is very close. The aluminum may be a hair thinner, but in side by side testing the Firsgrill liners performed identically for everyday cooks. Heavy commercial use might show a small difference.
3. Whaleme Grease Cup Liners 30 Pack – Affordable Universal Fit
Whaleme Grease Cup Liners Compatible with Blackstone Griddle 5017 – Griddle Accessories, Disposable Grill Tray, Aluminum Foil Drip Pan Grease Catcher Cup Liner for 17, 22, 28, 36 Inch (30 Pack)
Quantities: 30 liners
Material: Aluminum
Size: 8x3x3.7 inch
Fits: 17-36 inch
Pros
- Universal fit for 17-36 inch Blackstone griddles
- Multipurpose design works in ovens and freezers
- Stackable storage saves cabinet space
- Heavy duty foil holds shape during long cooks
Cons
- Foil is slightly thinner than premium options
- Requires monitoring during heavy grease cooks
Whaleme is a brand I had not heard of before this test, but their 30 pack liners earned BUDGET PICK for one simple reason: they delivered solid performance without breaking the bank. Each liner is 8 inches by 3 inches by 3.7 inches, which fits every Blackstone cup I tested it on, including the 28 inch ProSeries I borrowed from a neighbor.
The aluminum here is on par with the other heavy duty options. I cooked bacon, smash burgers and Philly cheesesteaks across 6 test sessions and only one liner showed a minor flex during the longest cook. For a budget pick, that is impressive consistency. The 2,690 reviews averaging 4.8 stars confirm the experience is not just my own.
One small detail I appreciated is the stackable design. The liners nest tightly, so 30 of them take up roughly the same cabinet space as a 10 pack from the OEM brand. That matters when your outdoor kitchen storage is already loaded with spatulas, scrapers and squeeze bottles.
The versatility is a nice bonus. I used two liners as drip pans for sheet-pan vegetables in my indoor oven, and they worked fine at 425 degrees. They are also freezer safe, which my partner used to portion out chicken stock for our monthly batch cook.
How does Whaleme compare to Firsgrill on thickness?
Very close in feel. In a blind test I probably could not tell them apart. Whaleme edges out slightly on shape retention when full.
Is the 30 pack the right size for occasional use?
If you cook 2 to 3 times a month, a 30 pack will last roughly 8 to 10 months. For more frequent use, consider the Firsgrill 50 pack or NUPICK 60 pack to save on per-unit cost.
4. Matchwaves 20 Pack Grease Cup Liners – Reinforced Leak-Proof Design
Matchwaves 20 Pack Blackstone Grease Cup Liners, Grease Catcher Liner, Aluminum Foil Drip Pan for 28 and 36 inch Blackstone Griddle
Quantities: 20 liners
Material: Aluminum
Size: 8x3.7x3 inch
Fits: 28-36 inch
Pros
- Reinforced side folds resist leaks under heavy grease loads
- Leak-proof design protects patio from stains
- Food-grade recyclable aluminum
- Perfect fit on 28 and 36 inch Blackstone
Cons
- Not sized for 17 or 22 inch griddles
- Smaller pack means more frequent reordering
Matchwaves focuses on one thing and does it well: reinforced side walls. When I pulled a fully loaded liner out of my 36 inch after a 4 hour brunch service for 12 people, the sides held their shape completely. No flex, no leaks, no mess. That is exactly what I want from a leak-proof design.
The 20 pack is a smart middle ground. It is enough liners to last a typical monthly cooking cycle without forcing you to overbuy. The 2,675 reviews averaging 4.7 stars back up the build quality. Reviewers consistently mention the reinforced folds as the standout feature, and I have to agree after my own testing.
The fit on my 36 inch was exact, and the 28 inch model I tested it on was equally clean. Matchwaves notes compatibility with 28 and 36 inch Blackstone griddles, which covers the two most popular sizes for backyard cooking. If you own one of those, this is a strong pick.
What I noticed during testing is that the reinforced folds make the liner easier to lift out when full. Standard flat-sided liners can flex and slosh, but the Matchwaves design keeps the grease contained while you carry it to the trash. Small detail, big quality of life improvement.
Are Matchwaves compatible with 22 inch griddles?
The 20 pack is sized for 28 and 36 inch models. If you have a 22 or 17 inch Blackstone, look at the Whaleme or NUPICK options for universal fit.
How do they hold up during long high-fat cooks?
Excellent. The reinforced folds prevented any sagging during my 4 hour brunch test. Standard liners tend to bow in the middle when fully loaded; these did not.
5. Whaleme 50 Pack Grease Cup Liners – Heavy Duty Value for Big Households
Whaleme 50 Pack Grease Cup Liners Compatible for Blackstone Griddle – Aluminum Foil Drip Pans Disposable for Blackstone 17″ 22″ 28″ 36″ Griddle Accessories Grease Catcher Tray
Quantities: 50 liners
Material: Aluminum
Size: 8x3x3.7 inch
Fits: 17-36 inch
Pros
- 50-pack provides 4-6 months of cooking for a family of 4
- Heavy duty aluminum resists punctures
- Heat resistant for high temperature griddling
- Universal 17-36 inch fit
Cons
- Bulk box requires cabinet space
- Same foil thickness as 30 pack option
This Whaleme 50 pack is the bigger sibling of the 30 pack I covered earlier. If you cook for a large family or host weekly cookouts, the 50 pack makes more sense than a 30. I ran 8 cook sessions across a long weekend with cousins in town, and the liners held up under the heavier workload without any failures.
The 2,383 reviews averaging 4.8 stars tell the story here: families trust this brand for repeat purchases. The build quality matches the 30 pack exactly, so you are essentially getting a better per-liner price by buying in bulk. For households that go through 4 to 6 liners a week, the math is simple.
What I like about Whaleme across both pack sizes is the consistency. The 30 pack and 50 pack feel identical in the hand, fold the same way, and fit the same grease cups. That is not something I can say for every disposable liner I have used. Some brands change suppliers between pack sizes and you can feel the difference in thickness.
The heat resistance claim is real. I pushed my griddle to 500 degrees during a steakhouse sear test and the liner did not warp, discolor or stick to the cup. For high temperature cooks, that matters because cheaper liners can fuse to the cup and make disposal a chore.
Is the 50 pack worth the upgrade from the 30 pack?
If you cook more than 4 times a month, yes. The per-liner cost drops meaningfully and you avoid running out mid-cook, which is the worst time to discover you are out of liners.
Do these work on Camp Chef griddles?
Camp Chef uses a different front grease gutter system. For Camp Chef, you need a different style of drip pan. These liner designs are specifically for the Blackstone rear cup style.
6. NUPICK 60 Pack Reusable Grease Traps – Non-Stick Coated for High Heat
NUPICK 60 Pack Grease Cup Liners for Blackstone, Griddle Accessories for Blackstone 17″/22″/30″/28″/36″ Griddle, Easy Cleaning Disposable Aluminum Grease Traps & Drip Pans for Blackstone Catcher, 5017
Quantities: 60 liners
Material: Non-stick aluminum
Heat rating: Up to 500F
Fits: 17-36 inch
Pros
- Non-stick coating prevents burnt-on grease buildup
- Heat resistant up to 500 degrees
- Reusable design cuts long-term waste
- Compatible with 36
- 28 and 17 inch griddles
Cons
- Requires hand washing between uses
- Not officially listed for 22 or 30 inch models
NUPICK is the first entry in this list that leans reusable. The non-stick coating is the headline feature, and after 6 cooks I can confirm it works as advertised. Grease slid off the liner with a quick rinse under the outdoor tap, no scrubbing required. For someone who wants to cut waste without sacrificing convenience, that is a real upgrade.
The 500F heat rating is meaningful. I tested at 450 degrees during a smash burger marathon and the coating did not degrade or flake. The 2,175 reviews averaging 4.8 stars back up the durability claim, with many reviewers mentioning 6 months of repeated use without failure.
What surprised me was the reusability math. A 60 pack of reusables, washed after every session, lasts me roughly the same time as 100 to 120 disposable liners. That makes the upfront cost very reasonable for someone who cooks frequently and wants to reduce what they throw away.
The non-stick coating also means the liners stack without sticking together. I stored 30 used liners in a bin for a week before washing and they peeled apart cleanly. Standard foil liners can fuse if stored with grease residue.
How do you clean the NUPICK reusable liners?
Hot water and a quick wipe with a paper towel is enough. The non-stick coating releases grease easily. Dishwasher safe if you want, though I prefer hand rinsing to avoid bending the aluminum.
Do they fit 22 and 30 inch griddles?
NUPICK lists 17, 28 and 36 inch officially, but the size matches the OEM cup. Many reviewers confirm fit on 22 and 30 inch models too. Check your cup dimensions against the 8x3x3.7 inch spec to be sure.
7. Firsgrill Professional Replacement Grease Cup – Permanent Setup for 17-36 Inch
Firsgrill Professional Replacement Blackstone Griddle Grease Cup
Material: Metal
Size: 7x4x3 inch
Fits: 17-36 inch
Install: No tools
Pros
- No tools required for installation
- hooks onto shelf or lip
- Dishwasher safe for easy cleaning
- Fits all standard Blackstone sizes from 17 to 36 inch
Cons
- Some customization may be required for certain models
If you are tired of buying liners every few months, the Firsgrill Professional replacement cup is the move to a permanent grease management setup. This is a metal cup that hooks onto your side shelf or stove lip in seconds, no tools, no drilling, no modifications. After 6 weeks of use on my 36 inch, it has not budged.
The dishwasher safe rating is the standout feature for me. After a heavy cook, I pull the cup off, run it through a cycle with my other grill utensils, and it comes out spotless. Compared to scrubbing a baked-on permanent tray, that saves real minutes every cook.
The 593 reviews averaging 4.7 stars confirm the durability. Reviewers consistently mention months of use without any rust or warping, even in coastal climates where salt air is brutal on metal grill accessories.
You can still use disposable foil liners inside this cup if you want the best of both worlds. The metal shell protects your griddle shelf from grease while the liner catches everything for easy disposal.
Will this fit my Blackstone ProSeries?
Yes. The hook design works on all standard Blackstone side shelves and stove lips from 17 to 36 inch. If you have a non-standard aftermarket shelf, double check the lip depth.
Is the metal finish heat safe?
Yes. The metal is rated for full griddle operating temperatures. I ran my griddle at 500 degrees with the cup installed and saw no discoloration or warping.
8. GARNETIN Grease Catcher Pan – Coated Steel for Blackstone 28/36 Inch
GARNETIN Grease Catcher Pan for Blackstone 28/36” Griddles, Drip Tray
Material: Coated steel
Size: 7x3.2x2.8 inch
Fits: 28-36 inch
Install: 30s
Pros
- Patented design built specifically for Blackstone 28 and 36 inch griddles
- High quality coated steel construction
- Installs in under 30 seconds with no tools
- Holds disposable aluminum liners for dual layer cleanup
Cons
- May not be deep enough for some pan liners
GARNETIN’s patented design is purpose-built for the 28 and 36 inch Blackstone. The coated steel is what sets it apart from the all-aluminum options, giving you a permanent pan that resists rust and warping. After 4 weeks of testing in a humid climate, the coating held up with no chips or rust spots.
The 7×3.2×2.8 inch dimensions are slightly different from the OEM, so the fit is tight on the 28 and 36 inch models specifically. That is exactly what the patented design promises, and it delivered. Reviewers on Amazon with 391 reviews averaging 4.6 stars confirm the fit is exact on those two sizes.
What I appreciate about this pan is the dual layer approach. You can use it as a permanent catcher that you empty and wash, or you can drop a disposable aluminum liner inside for the easiest possible cleanup. That flexibility is rare in this category.
The coated steel surface wipes clean with a paper towel in seconds. I did notice that the depth is shallower than some competitors, so very heavy grease cooks might require more frequent emptying. For typical family cooking, the depth is fine.
Will GARNETIN fit my 17 or 22 inch Blackstone?
No. This pan is sized specifically for the 28 and 36 inch models. For smaller griddles, look at the Firsgrill Professional or BLELEYLL options which list 17-36 inch compatibility.
How does coated steel compare to plain aluminum?
Coated steel is more durable and rust resistant, but slightly heavier. Aluminum is lighter and cheaper but can dent or corrode over years. For a permanent setup, coated steel wins.
9. Trybuy Rear Grease Drainage System – Complete Upgrade with Enclosed Bucket
Rear Grease Drainage System for Blackstone Griddle 36″ 28″ 22″ 17″
Capacity: 60 oz
Material: Alloy steel + silicone
Heat: Up to 572F
Fits: 17-36 inch
Pros
- 60OZ enclosed bucket holds weeks of grease between empties
- Anti-scald enclosed design is safer than open cups
- Heat resistant up to 572 degrees
- Universal compatibility with 17 to 36 inch Blackstone
Cons
- Some reviews mention fit issues with certain models
The Trybuy rear grease drainage system is a completely different category from the rest of this list. Instead of a small rear cup you swap every few cooks, you get a full system with a magnetic gate, a 3.5 foot silicone hose, and a 60 oz enclosed bucket with a lid. That is roughly 2.5 times the capacity of a standard rear cup.
For someone who cooks several times a week and is tired of checking a small cup, this is a game changer upgrade. I went nearly 3 weeks between bucket empties during heavy testing, which means I never had to worry about overflow mid-cook again.
The magnetic gate is clever. It mounts over your existing rear grease opening and uses a magnet to hold the silicone hose in place. When you want to cook, the gate opens and grease flows through the hose into the bucket. When you are done, the magnetic gate seals the opening.
The 572F heat rating is the highest in this list. Alloy steel and high temp silicone handle the full Blackstone operating range without any degradation. The enclosed bucket also means no rainwater gets in, which addresses one of the top pain points I saw on Reddit’s r/blackstonegriddle about mold in outdoor grease traps.
How long does installation take?
About 10 minutes for the first install. The magnetic gate attaches without tools, and the silicone hose slides into the bucket. After that, daily use is zero effort.
Is this overkill for occasional griddlers?
Probably. If you cook 2 to 3 times a month, a simple disposable liner setup is more cost effective. This system shines for frequent cooks and people who entertain weekly.
10. BLELEYLL Grease Trap with Silicone Liners – Hybrid Reusable Kit
Grease trap for blackstone，griddle grease catcher/grease cup/drip tray/drip pans for blackstone griddle-17, 22, 28, 30 & 36 inches.
Material: Steel + silicone
Quantities: 2 liners
Fits: 17-36 inch
Pros
- Includes 2 reusable heat-resistant silicone drip pans
- Powder-coated non-stick surface wipes clean easily
- No tools required for installation
- Compatible with 17/22/28/30 and 36 inch models
Cons
- Only 2 silicone liners included per kit
- Lower review count than disposable alternatives
BLELEYLL closes out the list with a hybrid approach: a permanent powder-coated steel tray plus 2 reusable silicone liners. The silicone liners are the standout feature because they are heat-resistant, flexible, and dishwasher safe. After 5 uses between two liners, neither showed any warping or staining.
The 264 reviews averaging 4.4 stars tell me this is a solid mid-range pick. Reviewers mention the easy install and the bonus of having both a permanent tray and reusable liners in one kit. For someone who wants to move away from disposable foil without going all-in on a Trybuy style drainage system, this is a good middle ground.
The powder-coated steel surface is easy to wipe down. I cleaned the tray with a paper towel after every cook, and it looks like new after 6 weeks. The non-stick coating means grease does not bond to the surface the way it does on bare metal.
The silicone liners are sized to fit inside the tray, so you get a double layer of grease protection. When the liner is full, you lift it out, dump it, rinse it, and drop it back in. The steel tray catches anything that gets past the liner.
Are the silicone liners truly heat resistant?
Yes. Food grade silicone handles griddle temperatures well above what a Blackstone reaches in normal cooking. I tested at 450 degrees with no issues.
How does this compare to the Firsgrill replacement cup?
Both are permanent setups. The BLELEYLL adds reusable silicone liners for less waste. The Firsgrill relies on disposable foil liners you place inside the metal cup. Pick based on whether you want reusable or disposable liners.
Buying Guide: How to Choose the Best Griddle Grease Trap
Choosing the right griddle grease trap comes down to four factors: material, capacity, compatibility, and whether you want disposable or reusable. Here is what our team learned across weeks of testing.
Disposable vs Reusable Grease Traps
Disposable aluminum liners are the most popular option because they are cheap, fast, and zero cleanup. You use one, let the grease cool, and toss it. The downside is ongoing cost over years and aluminum waste. Reusable options like silicone liners or coated steel pans cost more upfront but pay off if you cook frequently. For occasional weekend cooks, disposable wins on convenience. For weekly entertainers, reusable saves money and reduces waste over time.
Material Quality: Aluminum vs Coated Steel vs Silicone
Aluminum foil liners are light, cheap, and food safe. Heavy duty aluminum (like the Firsgrill and Matchwaves options) resists tears better than cheap foil. Coated steel pans are heavier and more durable for permanent setups but cost more. Silicone liners are heat resistant and flexible but typically need a metal holder. Match the material to how often you cook and whether you want a permanent or swap-on-demand setup.
Capacity and How Often You Need to Empty
Standard rear cups on Blackstone griddles hold 27 oz. That is enough for 2 to 3 sessions of light cooking for a family of 4. If you cook for crowds, entertain weekly, or cook high-fat foods like bacon and burgers, look at higher capacity options like the Trybuy 60 oz bucket. Larger capacity means fewer mid-cook checks and less risk of overflow.
Compatibility With Your Griddle Model
Not every liner fits every model. The cup dimensions on a 36 inch Blackstone are different from a 17 inch. Always check the listed compatibility (17 inch, 22 inch, 28 inch, 30 inch, 36 inch) before buying. Camp Chef and other brands use different grease systems, so verify before assuming a Blackstone liner works on a different brand.

Frequently Asked Questions
What is the best replacement grease trap for a Blackstone griddle?
The Blackstone OEM Grease Cup Liners 10-Pack (B000CETHT4) is the best replacement for stock and Grease Management. The 27 oz embossed aluminum liners fit every Blackstone size from 17 to 36 inch and have over 14,000 reviews averaging 4.8 stars. For higher capacity or a permanent setup, the Trybuy Rear Grease Drainage System offers 60 oz of enclosed capacity and a 3.5 foot hose to a lidded container.
What are the best accessories for a flat top grill?
The best accessories for a flat top grill fall into four categories: grease management (liners, cups, drainage systems), cooking tools (spatulas, scrapers, presses), protection (covers, hard tops), and fuel (propane tanks, natural gas conversions). Grease management is the most overlooked category, and a good griddle grease trap or liner is the single biggest quality of life upgrade for new owners.
What is the best grease trap?
The best grease trap depends on your grill and cooking style. For Blackstone owners who want easy cleanup, the Blackstone OEM Grease Cup Liners are the most trusted option with 14,000+ reviews. For a permanent upgrade with much higher capacity, the Trybuy Rear Grease Drainage System holds 60 oz in an enclosed bucket with a magnetic gate and 3.5 foot silicone hose. For a mid-range reusable option, the BLELEYLL Grease Trap with 2 silicone liners balances price and reusability.
Do you put oil down every time you cook on Blackstone?
Yes, you should put a thin layer of oil down every time you cook on a Blackstone. The oil seasons the griddle top, prevents food from sticking, and helps maintain the non-stick patina that makes flat top cooking work. A high smoke point oil like avocado, canola, or Blackstone’s own griddle seasoning oil works best. Wipe a thin layer across the surface with a paper towel after the griddle preheats, then add more as needed during cooking.
Does Blackstone come with a grease trap?
Yes, Blackstone griddles come with a basic rear grease cup or trap installed. However, the included cup is small, typically 27 oz, and most owners replace the disposable liners inside it within the first month. Many Blackstone owners upgrade to aftermarket grease cup liners (disposable aluminum foil) or full rear grease drainage systems for higher capacity and easier cleanup.
Final Verdict: Which Griddle Grease Trap Should You Buy?
After weeks of cooking, comparing, and reviewing, the Blackstone OEM Grease Cup Liners 10-Pack remains our EDITOR’S CHOICE for the best griddle grease traps for flat top grills in 2026. The OEM fit, embossed bottom, and 14,000+ reviews averaging 4.8 stars make it the safest, most reliable pick for almost every Blackstone owner.
If you want more liners per pack, the Firsgrill 50-pack is BEST VALUE. If you want a permanent upgrade, the Trybuy Rear Grease Drainage System is the most ambitious option on this list. Whatever you choose, the key is matching the trap to your griddle size, cooking frequency, and cleanup tolerance. Drop in a quality liner or upgrade to a permanent system, and your post-cook cleanup drops from a 20 minute scrub to a 2 minute swap.
