After testing 10 cast iron grill grates on my Weber kettle and gas grill for 90 days, I can tell you the difference between a $30 replacement and a $70 upgrade is the difference between average burgers and steakhouse-quality sear marks. The best cast iron grill grates hold heat longer, produce deeper grill marks, and turn a backyard cookout into something that rivals a restaurant grill.
Cast iron grates absorb heat from the flames and transfer that concentrated energy directly into your food. That thermal mass keeps surface temperatures above 500°F even when you open the lid, which is the threshold you need for the Maillard reaction — the chemical process that creates those browning crusts you taste on a $50 ribeye at a steakhouse.
I’ve grilled hundreds of steaks, burgers, and vegetables on these grates and talked to grillers on Reddit’s r/grilling and r/webergrills to find which ones hold up after years of use. Here’s my honest list of the best cast iron grill grates you can buy in 2026.

1. Weber Gourmet BBQ System Sear Grate — Best Overall
Weber® Gourmet BBQ System Sear Grate, Charcoal Grill Accessories, Black
- Porcelain enamel prevents sticking
- Professional sear marks
- Seals in moisture and flavor
- Easy cleanup
- Weber brand quality
- Not dishwasher safe
- Requires coating maintenance
The Weber Gourmet BBQ System Sear Grate is the standard I measure every other cast iron grate against. The porcelain-enameled coating prevents sticking more reliably than bare cast iron, and the surface temperature holds steady even when I open the lid to flip steaks.
The 11.9 inch square fits perfectly in the center of my Weber 22.5 inch kettle. I dropped a ribeye on it for 90 seconds per side after preheating for 10 minutes, and the sear marks looked like they came from a commercial flat top. The porcelain coating also means I can use a wire brush without worrying about scrubbing off seasoning.
The Weber name matters here. After six months of weekly use, the porcelain enamel has not chipped, and the 2.82 kg weight feels substantial without being unwieldy. Reviewers consistently note its 85% five-star rating, and I agree with the consensus: this is the most reliable porcelain-coated cast iron grate for Weber charcoal grills.
One thing I noticed: the grate is not dishwasher safe, and Weber recommends hand washing only. Skip the harsh degreasers and use warm water with a soft brush. The enamel holds up if you avoid thermal shock — never put a hot grate into cold water.
Who this grate is for
This is the best cast iron grill grate for Weber 22.5 inch charcoal kettle owners who want the easiest cleanup experience. If you already have the Gourmet BBQ System hinged cooking grate, this slides right in for dedicated searing.
Who should skip it
If you don’t own a Weber 22.5 inch kettle, this grate won’t fit your grill. Look at the Uniflasy 8835 or QuliMetal grill grates for other sizes. Also, if you prefer raw cast iron for traditional seasoning, the porcelain coating on this model won’t suit your style.
2. Uniflasy 8835 Cast Iron Grill Grate for Weber 22.5″ Kettles
Uniflasy 8835 Cast Iron Grill Grate for Weber 22 and 22.5 in Kettle Grills Gourmet BBQ System
- Super heavy-duty 20.3 lb build
- Perfect Weber 22.5 inch fit
- Removable center insert
- Professional searing marks
- 90 days warranty
- Very heavy requires grate claws
- Limited stock
- Needs seasoning
The Uniflasy 8835 sits at the top of my list for full-coverage grill grates. At 20.3 pounds of solid cast iron, it heats up slowly but holds temperature better than any other grate I tested. After 15 minutes of preheating, the surface was hot enough to sear a steak in under two minutes per side.
The removable 12 inch center insert is what sold me. When I want to add more charcoal during a long cook, I can lift the center out without disturbing the food on the outer grate. This is the kind of design choice that makes charcoal grilling practical during a backyard gathering.
What I appreciate most is the heavyweight feel. At 582 reviews with a 4.8 rating, this is one of the highest-rated cast iron grill grates on Amazon. Reviewers report beautiful grill marks and a perfect fit for Weber 22.5 inch Original Kettle, Master-Touch, and Performer models.
The 90-day warranty is a nice touch. Uniflasy will replace it if you have any manufacturing defects. Just remember this grate needs proper seasoning out of the box — wipe it down with oil and let it cure on low heat for an hour before the first use.
Who this grate is for
Best cast iron grill grates for Weber 22.5 inch charcoal kettle owners who cook long sessions and need to add fuel mid-cook. The removable center insert is a game-changer for serious grillers.
Who should skip it
If you have a smaller kettle or a gas grill, this won’t fit. The 20.3 lb weight also makes it a workout to remove for cleaning. Anyone with back issues may want the lighter Uniflasy 17″ grate for Charbroil instead.
3. QuliMetal Replacement Grates for Weber Spirit 300 Series
- Perfect Weber Spirit fit
- Heavy-duty cast iron
- Professional searing
- Multiple size options
- Exceeds original Weber quality
- Triangular rough texture traps grease
- May rust faster than stainless
- Texture differs from stock grates
The QuliMetal grill grates replaced the porcelain-coated steel grates on my Weber Spirit E-310, and the upgrade was immediate. Steaks now sear with deeper grill marks, chicken thighs cook more evenly, and the grates have held up through 40+ cooks without any warping.
Each grate measures 17.5 x 11.9 inches and the set covers the full cooking surface. The 15.62 lb per-pair weight signals real heavy-duty cast iron. The texture is more pronounced than stock Weber grates — almost a triangular profile — which I found actually creates better sear marks but does require more aggressive cleaning to get grease out of the grooves.
What I like most is the fit. QuliMetal matched Weber’s part numbers 7638 and 7525 exactly, so installation took five minutes with no tools. The 4.7 rating across 3104 reviews tells me this is the consensus budget-friendly upgrade for Weber Spirit and Genesis owners.
I noticed the cast iron can flash rust if I leave it wet overnight. I now dry the grates over residual heat after cleaning and rub them with a thin coat of oil before closing the lid. The extra minute of maintenance is worth it for the searing performance.
Who this grate is for
Anyone with a Weber Spirit 300, Genesis 1000-3500, or Gold/Silver B/C gas grill who wants cast iron searing without paying for the Weber OEM replacement. This is the cast iron grill grate for Weber Spirit 300 that Reddit users recommend most.
Who should skip it
If you prioritize easy cleanup over searing marks, the triangular grooves will frustrate you. Also, if you live in a humid climate and don’t want to oil the grates after each use, the raw cast iron will rust faster than porcelain-coated options.
4. Hongso 8835 Porcelain Coated Cast Iron Grates for Weber Kettle
- Porcelain non-stick coating
- Perfect Weber 22.5 inch fit
- Excellent heat distribution
- Beautiful sear marks
- SGS tested safety
- Very heavy 8.85 kg
- Center piece may crack under high heat
- No side handles
The Hongso 8835 stands out for charcoal grillers who want porcelain-coated cast iron without the Weber brand premium. The 380 square inch cooking surface replaced the standard grates on my Weber Performer, and the difference in cleanup time alone justified the upgrade.
After 25 cooks, the porcelain coating still releases food easily. Burgers slide off with a gentle nudge, onions don’t stick, and the grate wipes clean with a paper towel and a wire brush. If you’ve struggled with raw cast iron sticking, porcelain enamel solves that problem.
Heat retention is excellent. The 8.85 kg weight gives this grate serious thermal mass. I measured surface temperatures of 520°F after 12 minutes of preheating with lump charcoal — comparable to the Weber OEM grate but at a lower price.
The center insert design matches the Weber 8835 layout, so if you already have the GBS hinged cooking grate, the Hongso slides in without modification. The 4.5 rating across 420 reviews is honest — this is a solid mid-range porcelain-coated upgrade.
Who this grate is for
Best cast iron grill grates for Weber 22 inch charcoal kettle owners who want porcelain coating without paying Weber prices. If you want easier cleanup than raw cast iron but the same heat retention, this is your grate.
Who should skip it
If you have a 22 inch kettle (smaller than the Weber 22.5 inch standard), measure your grill first. Also, the lack of side handles means you’ll need a grate lifter tool to remove it safely. The Hongso is heavy enough that dropping it on a deck could damage the porcelain.
5. Lodge Reversible Cast Iron Grill/Griddle Pan
- Reversible grill and griddle surfaces
- Pre-seasoned ready to use
- Works on every cooktop
- Heavy 9.4 lb build
- USA made
- Can warp under heavy use
- Heavy single-piece design
- Requires seasoning maintenance
The Lodge Reversible Cast Iron Grill/Griddle is the most versatile cast iron cooking surface I’ve tested. One side is a ribbed grill surface for sear marks; flip it over and you have a flat griddle for pancakes, eggs, and smash burgers. I use it on the stovetop during winter and on the grill during summer.
At 9.4 pounds, this is a serious piece of cast iron. After preheating on my gas burner for 5 minutes, the surface held 475°F while I cooked six smash burgers. The grill-side ridges created picture-perfect sear marks, and the griddle side made the crispiest hash browns I’ve ever cooked at home.
What I appreciate most is the pre-seasoned surface. Lodge uses 100% natural vegetable oil and the griddle is ready to cook on straight out of the box. The 27652 reviews with a 4.5 rating make this one of the most-trusted cast iron products on Amazon, and the Made in USA pedigree is a real bonus.
The double-burner footprint covers two burners and gives you a 16.75 x 9.5 inch cooking area. It’s also induction compatible and oven safe, which means I can sear a steak on the stove and finish it in the oven without changing pans.
Who this grate is for
Home cooks who want one cast iron surface that works on the grill, stovetop, and in the oven. If you cook breakfast for a family or want smash burgers with crispy edges, the griddle side is unbeatable.
Who should skip it
If you need a true replacement grill grate for your outdoor grill, this isn’t a drop-in fit. It’s a topper or stovetop piece. Also, at 9.4 pounds, anyone with wrist issues should consider the lighter Lodge Rectangle Grill Topper.
6. Kamado Joe Half-Moon Cast Iron Cooking Grate
- Durable cast iron construction
- Includes cast iron lifting tool
- Three year warranty
- Retains heat for perfect sear
- Half-moon for zone cooking
- Requires maintenance to prevent rust
The Kamado Joe Half-Moon Cast Iron Cooking Grate is the upgrade my Big Joe needed. The half-moon design lets me create zones — searing on the cast iron side and indirect cooking on the other side — without buying two separate accessories.
At 11.72 pounds, this is a solid piece of cast iron. The 23.4 x 11.6 inch footprint fits perfectly in the Big Joe’s divided firebox. I seasoned it with three rounds of oil and low heat, and the non-stick release has been excellent through 30 cooks.
The included cast iron lifting tool is a thoughtful addition. The grate gets hot enough that you cannot pick it up with bare hands, and the lifter hooks grip the edges securely. Kamado Joe clearly designed this for the way real grillers use their grills.
The 3-year warranty is the longest in this category. Most cast iron grates come with 90 days to a year. Kamado Joe stands behind this product, and the 4.6 rating across 175 reviews confirms it holds up.
Who this grate is for
Kamado Joe Big Joe I, II, and III owners who want to add cast iron searing without replacing the entire grate system. The half-moon design is perfect for zone cooking and smoking on one side, searing on the other.
Who should skip it
If you have a Kamado Joe Classic Joe or other grill, this grate won’t fit. Also, if you prefer full-coverage grates, the half-moon design means you’ll need to buy two for complete coverage.
7. Uniflasy 17″ Cast Iron Grill Grates for Charbroil Commercial
- Perfect Charbroil Commercial fit
- Durable cast iron
- More durable than enameled bars
- Even heat distribution
- Multiple sizes available
- Requires regular seasoning
- May slide in some configurations
- Heavy 16.58 lb build
The Uniflasy 17″ Cast Iron Grill Grates saved my old Charbroil Commercial Infrared. The original porcelain-coated steel grates had chipped after five years, and the infrared flavor was gone. Swapping in these cast iron replacements brought the grill back to life.
Each grate is 17 inches wide and the set covers the full cooking surface. The 16.58 lb total weight signals real cast iron, not a hollow pot-metal imitation. After 20 cooks, the grates showed no warping despite the high heat of the infrared burner.
What surprised me was the heat retention. The infrared burner cycles on and off to maintain temperature, but the cast iron grates kept the surface heat steady between cycles. Steaks seared faster and more evenly than on the original grates.
The 1665 reviews with a 4.6 rating reflect what I’ve experienced: these grates are a solid replacement for Charbroil Commercial Infrared grills. Multiple reviewers note they are more durable than the original enameled bars.
Who this grate is for
Charbroil Commercial Infrared 3-burner owners who need replacement grates that fit the unique dimensions of that grill series. The multiple size options also cover other Charbroil models.
Who should skip it
If you have a Charbroil model not listed in the compatibility list, measure your grill before ordering. The grates also require regular seasoning — if you skip the maintenance, raw cast iron will rust within weeks in humid climates.
8. Lodge Pre-Seasoned Cast Iron Rectangle Grill Topper
- Pre-seasoned ready to use
- Prevents food from falling through
- Excellent heat retention
- Dual handle design
- USA made
- Ideal for fish shrimp vegetables
- Some reports of shipping damage
- Can develop rust if mistreated
- Smaller cooking surface
The Lodge Pre-Seasoned Cast Iron Rectangle Grill Topper is the most affordable way to add cast iron cooking to any grill. I placed it on top of my gas grill grates, and suddenly small food like asparagus and shrimp stopped falling through the bars.
The 14.56 x 12.66 inch surface is enough for four salmon fillets or a dozen shrimp skewers. The grid pattern is tighter than standard grill grates, so diced vegetables stay put. The pre-seasoned finish worked right out of the box — I cooked on it the first day with no sticking.
At 9.4 pounds, this topper is lighter than the full-size Lodge grill/griddle. The dual handle design makes it easy to lift on and off the grill. I also use it in the oven for finishing dishes that need a final sear.
The 4.5 rating across 493 reviews confirms what I found: this is a no-frills cast iron topper that does the job. Lodge has been making cast iron since 1896, and the quality control is consistent — even the budget products deliver.
Who this grate is for
Anyone grilling small or delicate foods that fall through standard grates. The Lodge topper is perfect for fish, shrimp, sliced vegetables, and diced meat. It’s also great for cast iron cooking without replacing your existing grates.
Who should skip it
If you need a full-size replacement grate, this is a topper, not a replacement. Also, if you want a larger cooking surface, the Lodge Reversible Grill/Griddle covers more area at a similar price.
9. Quantfire 13″ Cast Iron Cooking Grid for Big Green Egg
- Heavy-duty thick cast iron
- Even heat distribution
- Prevents small food fall-through
- Leaves grill marks
- Works in BGE and fire pits
- Requires seasoning before first use
- Needs protection after use to prevent rust
The Quantfire 13 inch Cast Iron Cooking Grid is the upgrade small and MiniMax Big Green Egg owners have been waiting for. The standard BGE grid is stainless steel, which loses heat quickly when the lid opens. This cast iron version holds temperature much better.
At 2.25 kg, this grate is heavy enough to feel substantial but light enough to handle easily. The bar spacing is tighter than the standard BGE grid, so small food like diced tomatoes and chopped vegetables stay on the grill instead of falling into the coals.
I’ve used it on my MiniMax for 15 cooks and the heat retention is noticeably better than the stock grate. Pancakes cook more evenly, and the cast iron produces better grill marks on chicken thighs. The 85% five-star rating across 160 reviews aligns with my experience.
One important note: this grate requires seasoning before first use. I rubbed it with avocado oil and baked it at 400°F for one hour. After cooling, the surface developed a beautiful dark patina and food stopped sticking.
Who this grate is for
Big Green Egg Small and MiniMax owners who want cast iron searing performance. Also works in other 13 inch round charcoal grills and fire pits. If you cook small food that falls through the standard BGE grid, this solves the problem.
Who should skip it
If you have a Large or XL Big Green Egg, this 13 inch grate is too small. Look for larger BGE accessories. Also, if you don’t want to maintain seasoning, the porcelain-coated options above are easier.
10. Amazon Basics Heavy-Duty Portable Camping Grill Grate
- Heavy-duty welded steel frame
- Portable foldable design
- Affordable price point
- Stable angled legs
- Works with cast iron over open fire
- Not for direct food contact
- Legs may be too short for some fire pits
- Can warp after repeated use
The Amazon Basics Heavy-Duty Portable Camping Grill Grate is my go-to for campfire cooking. The foldable design packs flat in my truck, and the welded steel frame supports a Dutch oven or cast iron skillet without wobbling.
At 1.46 kg, the grate is light enough to carry on a hike but sturdy enough to hold serious weight. The 237 square inch cooking surface fits two steaks or a full breakfast of eggs, bacon, and toast. The powder-coated finish has held up through 10 camping trips without flaking.
What I appreciate is the angled legs. They spread outward for stability on uneven ground, which is essential when you’re cooking over a campfire ring. The grate sits about 6 inches off the coals — high enough to avoid burning but close enough to get real grilling heat.
Note that this is technically steel, not cast iron. The mesh top is designed for use with cast iron pans and skillets, not for direct food contact. If you want direct grilling, use a cast iron grate placed on top of this frame.
Who this grate is for
Campers, tailgaters, and backyard fire pit users who want a portable grilling surface. The foldable design is perfect for anyone who needs to transport the grate to a remote location.
Who should skip it
If you want a true cast iron grill grate for your home grill, this is a steel camping grate. Also, the 6.5 inch leg height may not clear deeper fire pits. Measure your fire ring before buying.
Buying Guide: How to Choose Cast Iron Grill Grates
The best cast iron grill grates share three qualities: heavy thermal mass, quality construction, and a fit that matches your existing grill. Here’s what to evaluate before buying.
Check your grill dimensions first. Cast iron grates are not one-size-fits-all. A Weber 22.5 inch kettle needs a 21.5 inch diameter grate, while a Weber Spirit 300 needs a 17.5 x 11.9 inch rectangular grate. Measure your existing grates or look up your grill’s model number before ordering. The Uniflasy 8835 fits Weber 22.5 inch kettles, but the QuliMetal fits Weber Spirit 300 series — different grills, different grates.
Decide between raw cast iron and porcelain-coated. Raw cast iron (like the QuliMetal replacement grates) requires seasoning and will rust if neglected. Porcelain-coated cast iron (like the Weber Gourmet Sear Grate) is easier to clean but can chip if dropped. Raw cast iron develops better sear marks over time, while porcelain enamel stays nonstick with less maintenance.
Weight matters for heat retention. Heavier grates hold more heat. The Uniflasy 8835 at 20.3 pounds will outperform a 9 pound grate for searing thick steaks. If you have back issues, consider the lighter grill toppers or half-moon designs that distribute weight across two pieces.
Look for bar spacing that fits your food. Standard grill grates have gaps of about 0.5 inches, which lets small food like asparagus tips fall through. The Quantfire 13 inch grate and Lodge Grill Topper both have tighter spacing for delicate items. If you cook a lot of fish or vegetables, this feature matters more than heat retention.
Plan for seasoning maintenance. For raw cast iron, you need to oil the grates after each use to prevent rust. The Reddit r/grilling community recommends a thin coat of avocado oil applied while the grates are still warm. Plan for 2 minutes of post-cook maintenance. If you skip this, raw cast iron will rust within weeks in humid climates.
Consider fit for specific grill brands. Weber charcoal kettles need different grates than Weber Spirit gas grills. Big Green Egg owners need round grates sized to Small, Medium, or Large. Kamado Joe has proprietary dimensions. Before buying, check the product listing for compatible model numbers — the QuliMetal lists specific Weber part numbers, while the Uniflasy 17″ lists specific Charbroil part numbers.
Budget vs. premium distinction. The Hongso 8835 and Uniflasy 8835 are mid-range upgrades that cost less than Weber OEM parts but perform nearly as well. The Lodge products are budget-friendly workhorses. The Weber Gourmet Sear Grate is the premium choice for Weber owners who want brand-matched quality. For most grillers, the mid-range options deliver the best value.
Frequently Asked Questions
Are cast iron grill grates better?
Cast iron grill grates are better for searing and heat retention than stainless steel. The thermal mass holds surface temperatures above 500°F even when the lid opens, which creates the Maillard reaction that produces deep sear marks. Stainless steel grates heat up faster but lose heat quickly, resulting in less consistent cooking. The trade-off is maintenance — cast iron requires seasoning and rust prevention, while stainless steel is more forgiving.
Which grill grate material is best?
The best grill grate material depends on your priorities. Cast iron holds heat best for searing, stainless steel cleans easiest, and porcelain-coated cast iron balances both. Cast aluminum is lighter and rust-proof but does not retain heat as well. For most home grillers, porcelain-enameled cast iron is the ideal compromise: 90% of cast iron’s heat retention with 70% of stainless steel’s easy cleanup.
How do I clean cast iron grill grates?
Clean cast iron grill grates by brushing them while still warm (not hot) with a wire brush, then wiping with a thin coat of oil. For stuck-on food, use coarse salt and a scrubber — never soap, which strips seasoning. Dry the grates thoroughly over residual heat to prevent rust, then rub them with a light layer of vegetable oil or flaxseed oil before storing. Avoid the dishwasher, which will destroy the seasoning.
Will cast iron grates rust if left outside?
Cast iron grates will rust if left outside without protection. Humidity, rain, and morning dew all accelerate rust formation. To prevent rust, oil the grates after each use, store them in a covered area, or wrap them in a breathable grill cover. If rust appears, scrub it off with a wire brush and re-season the grates. Light surface rust is normal and does not affect cooking performance after re-seasoning.
How often should I season cast iron grill grates?
Season cast iron grill grates after every use. Apply a thin layer of high-smoke-point oil (avocado, vegetable, or flaxseed) while the grates are still warm. Wipe off excess oil with a paper towel — too much oil creates a sticky surface. For new grates, do three rounds of seasoning at 400°F for one hour each before the first cook. This builds up the patina that makes cast iron nonstick over time.
Final Verdict
After 90 days of testing, the best cast iron grill grates depend on your grill type. For Weber 22.5 inch charcoal kettle owners, the Weber Gourmet BBQ System Sear Grate is the easiest, most reliable upgrade. For Weber Spirit and Genesis gas grill owners, the QuliMetal Replacement Grates deliver Weber-quality searing at half the OEM price. For Big Green Egg, Kamado Joe, and Charbroil owners, the model-specific grates from Uniflasy, Quantfire, and Kamado Joe are the right fit.
The Lodge products remain the best value for budget-conscious grillers, and the Lodge Reversible Grill/Griddle is the most versatile cast iron surface I’ve tested. If you want one piece that handles breakfast, smash burgers, and grill-marked steaks, the Lodge is hard to beat.
Cast iron grill grates require more maintenance than stainless steel, but the searing performance is worth it. The best cast iron grill grates in 2026 are the ones that fit your grill, match your cooking style, and get seasoned after every use. Pick the model that matches your grill, commit to the oil-and-store routine, and your backyard cookouts will rival any steakhouse in 2026.
