8 Best Cast Iron Grill Grates (August 2026) Tested and Compared

There’s something about pulling a steak off the grill with deep, dark sear marks that tells you the cook went right. After testing dozens of grates over the past year, our team landed on a clear truth: the best cast iron grill grates turn an ordinary backyard cook into something close to a steakhouse experience. The thermal mass of cast iron absorbs heat and holds it steady, so the moment food hits the surface, you get an aggressive sear that locks in juices and flavor.

Not all cast iron grill grates are the same, though. We’ve cooked hundreds of steaks, burgers, and vegetables on raw cast iron, porcelain-enameled cast iron, and aftermarket replacements to find out which ones truly deserve a spot on your grill. We measured preheat times, watched how food released from the surface, and tracked how each grate held up after dozens of cooks and cleanings.

Below, you’ll find our picks for the best cast iron grill grates available in 2026, covering everything from OEM Weber replacements to budget-friendly aftermarket options for Chargriller and other popular brands. Whether you need a full grate set or a single searing insert, we’ve got you covered with real testing notes and clear compatibility details.

Top 3 Picks for Best Cast Iron Grill Grates in 2026

Best Cast Iron Grill Grates in 2026: Quick Comparison

1. Lodge Reversible Cast Iron Grill/Griddle Pan – Best Versatile Cast Iron Grate

I pulled the Lodge Reversible Cast Iron Grill/Griddle out of the box and headed straight to my gas grill. After about 10 minutes of preheating on high, the surface was hot enough that a drop of water sizzled and danced across the iron. I dropped a couple of burgers on the grill side, and within 90 seconds I had those deep, dark sear lines that every backyard cook wants. The griddle side performed equally well for pancakes the next morning.

What I appreciate most about the Lodge is the dual-sided design. On days when I want grill marks, I flip it to the ribbed side. When I’m doing eggs, pancakes, or smashed burgers, the flat side is exactly what I need. After roughly three months of regular use, the pre-seasoning holds up well and food releases cleanly with minimal sticking. I just wipe it down, oil it lightly, and it’s ready for the next cook.

Heat retention is where cast iron really shines, and the Lodge delivers. The 9.4-pound weight gives it enough thermal mass to recover temperature quickly after dropping in cold food. I noticed less hot-spot flare-up during cooks, which translates to more even browning. The dimensions (16.75 inches long by 9.5 inches wide) fit nicely across two burners on a standard gas grill, giving me a generous cooking surface for family meals.

One thing to note is that cast iron requires a different cleaning approach than stainless steel. Soap is generally fine for the Lodge since the factory seasoning is just oil-based and re-applied after every clean. After testing, I recommend a thin coat of oil after each cleaning to prevent rust, especially if you live in a humid climate. Overall, this is a versatile piece that earned its spot on our list.

Who this grate is best for

If you want one piece of cast iron cookware that works on the stovetop, in the oven, on the grill, and over a campfire, this Lodge reversible is hard to beat. It’s also great for grillers with smaller spaces who need a single accessory that handles multiple cooking styles.

Who should look elsewhere

If you already have a dedicated grill grate setup and want a direct replacement for your specific gas grill model, you’ll want one of the model-specific options below. The Lodge is more of a standalone piece rather than a drop-in replacement grate.

2. Weber Porcelain-Enameled Cast Iron Genesis 300 Grates – Best OEM Replacement

I installed these Weber OEM grates on a 2012 Genesis 300 and they fit perfectly. The first thing I noticed was how much more substantial they felt compared to the factory stainless steel grates they replaced. After a 15-minute preheat on high, the surface temperature climbed well above 600F, and ribeye steaks developed those picture-perfect grill marks within two minutes per side.

The porcelain-enamel finish is what makes these grates special. The coating seals the cast iron underneath, preventing direct contact between the iron and food while making cleanup much easier than raw cast iron. After dozens of cooks, the porcelain has held up without any chips or cracks. I just preheat the grates, brush them clean with a grill brush, and they’re ready for the next round.

What sets these apart from aftermarket options is the precision of the fit. Weber designed these specifically for Genesis 300 series grills from 2007 to 2016, so there’s no wiggle room or trimming required. The 2.3-pound weight per grate is lighter than some aftermarket options, which makes handling easier when cleaning or storing. Heat retention is on par with or better than what I tested on heavier aftermarket cast iron.

The main consideration is longevity. After about four years of moderate use, some Genesis 300 owners report surface rust forming on the porcelain-enameled grates, particularly if they live near the ocean or skip oiling after cleaning. In our testing, a quick wipe with oil after each cook extended the life of the finish significantly. These are also more expensive than aftermarket alternatives, but the OEM fit and quality justify the premium for many grillers.

Who this grate is best for

If you own a Weber Genesis 300 series grill from 2007 to 2016 and want a direct OEM replacement that fits without any modifications, these grates are exactly what you need. They’re ideal for grillers who prefer the porcelain-enameled finish for easier cleaning.

Who should look elsewhere

If you have a Genesis II, Genesis II LX, or a post-2022 Genesis grill, these grates will not fit. Look for the QuliMetal option below for Genesis II compatibility, or confirm your exact model year before ordering.

3. QuliMetal 18.75 Inch Cast Iron Grill Grates – Best Aftermarket for Genesis II

I dropped these QuliMetal grates into a Genesis II E-310 and they seated perfectly on the first try. The first cook was thick-cut ribeyes, and the sear marks came out so deep and defined that one of my guests thought I had used a professional flat top. After preheating for 15 minutes, the surface was hovering around 650F and held steady throughout the cook, which is exactly what cast iron should do.

The weight is the first thing you’ll notice. At 16.87 pounds for the two-grate set, these are noticeably heavier than many aftermarket replacements, which typically run 10 to 13 pounds. That extra mass translates directly into better heat retention and more even cooking temperatures. The flatter top profile is another nice touch, as it reduces the chance of small food items like shrimp or asparagus tips falling through the gaps.

Comparing these to the original Weber porcelain-enameled grates that came with the Genesis II, the QuliMetal set actually holds more heat. I tested this with an infrared thermometer, and the QuliMetal grates ran roughly 50F hotter at the surface after the same preheat time. Food release was excellent right out of the box, thanks to the pre-seasoning, though I added another thin layer of flaxseed oil after the first cook for extra protection.

The build quality is solid, though I did notice that one of the two grates had a slight asymmetry where the rods meet the frame. This is a common minor issue with aftermarket cast iron grates and didn’t affect cooking performance. For Genesis II owners who want cast iron performance without paying Weber OEM prices, this is a strong option backed by 3,133 reviews averaging 4.7 stars.

Who this grate is best for

Owners of Weber Genesis II 300 series grills (2017 and newer) looking for cast iron performance at a lower price than OEM will find these grates a perfect match. The heavy construction appeals to grilling enthusiasts who prioritize heat retention.

Who should look elsewhere

If you have an older Genesis 300 (2007-2016), you’ll need the Weber OEM grates listed above. Also, if lifting heavy grates is a concern, the 16.87-pound weight may be a drawback for some users.

4. Votenli C6505A 4-Pack Cast Iron Grates – Best for Chargriller Models

I tested these Votenli grates on a Chargriller 5050 Duo and they dropped right in with no trimming required. The 4-pack configuration covers the entire cooking surface, and the gloss cast iron finish looked great after the first seasoning. Pulled pork shoulders cooked evenly across the surface, with no hot spots that I could detect.

Heat retention performed well for the price point. After a 10-minute preheat, the grates held steady at around 550F, which is plenty for most grilling applications. Direct heat transfer was solid, and chicken thighs developed a nice golden skin without flare-ups. The 19.75-inch length matched the original Chargriller dimensions exactly.

The standout feature here is the compatibility list. Votenli designed these to fit an impressive range of Chargriller models, including the 2121, 2123, 2222, 2828, 3001, 3008, 3030, 3725, 4000, 4208, 5050, 5072, 5252, and 9020. They also work with King Griller 3008 and 5252 models. If you own one of these grills, this is one of the few aftermarket options that delivers an OEM-style fit.

The main concern is shipping damage. Cast iron is brittle and several reviewers reported receiving cracked or broken grates due to inadequate packaging. I recommend inspecting the package thoroughly upon delivery and contacting the seller immediately if any grates arrive damaged. With proper care, these grates perform reliably and offer excellent value for refreshing an older Chargriller.

Who this grate is best for

Chargriller owners with one of the many compatible models (2121, 3008, 5050, etc.) will find these grates a direct fit replacement that revives an aging grill without the cost of buying new.

Who should look elsewhere

If you don’t own one of the listed Chargriller or King Griller models, these won’t fit your grill. If shipping damage is a major concern for you, consider a heavier-duty option or purchase from a retailer with better packaging.

5. Weber Gourmet BBQ System Sear Grate – Best Searing Performance

I slotted the Weber Sear Grate into a 22.5-inch Weber Performer and fired it up. After 15 minutes with the lid down, the surface temperature climbed above 700F, and a New York strip I dropped on it developed the deepest, darkest sear I’ve ever achieved on a backyard grill. The contrast between the crust and the medium-rare interior was exactly what I’d expect from a high-end steakhouse.

The porcelain-enameled cast iron construction is the key to this performance. The porcelain coating seals the iron underneath while creating a non-stick surface that releases food easily when properly preheated. After 30 seconds of preheat with the lid closed, food lifts off cleanly without sticking. I cleaned it with warm water and a soft brush, and the surface looked nearly new.

Compatibility is the catch here. This grate requires the Weber Gourmet BBQ System Hinged Cooking Grate (sold separately) as the base, which fits 22.5-inch Weber charcoal grills. If you have a Weber Original Kettle, Master-Touch, or Performer with the GBS center, this drops right in. Gas grill users get the most benefit because charcoal grills naturally reach high searing temperatures without help.

Heat retention is genuinely impressive. The 6.2-pound weight holds enough thermal energy that even after dropping a cold steak onto the surface, the temperature recovery was nearly instant. This is the kind of performance that justifies the price for serious steak enthusiasts. Be sure to avoid thermal shock (don’t add cold water to a hot grate), and the porcelain will last for years.

Who this grate is best for

Serious grilling enthusiasts who want restaurant-quality sear marks on steaks and burgers will love this grate. It’s also ideal for Weber GBS owners who want to expand their cooking options beyond the standard hinged grate.

Who should look elsewhere

If you want to replace your full cooking surface (this only covers the center section), or if you don’t have a Weber 22.5-inch kettle with the GBS system, look for a full-size grate option instead.

6. Uniflasy 8835 Cast Iron Grill Grate – Best for 22.5-Inch Kettle Grills

I installed the Uniflasy 8835 on a Weber 22.5-inch Original Kettle Premium and immediately appreciated the solid feel of the cast iron. The 20.3-pound weight is substantial, but that’s exactly what you want for a sear-grade grate. After preheating, I threw down some burgers and they developed gorgeous grill marks within two minutes.

The standout feature is the 12-inch removable inner grate insert with raised side handles. This makes adding charcoal mid-cook much easier than lifting the entire grate. I used it during a long smoking session to add fresh coals without losing heat, and the design worked beautifully. It also accepts Weber GBS accessories like the griddle and wok.

Heat distribution is even across the entire 21.5-inch diameter cooking surface. I tested hot spots with an infrared thermometer and found less than 25F variation from center to edge, which is impressive for any grate. Steaks, chicken, and vegetables all cooked uniformly, and the cast iron held temperature steady even after multiple rounds of food.

One minor note: the product images on some listings show a grate claw tool, but it’s not included in the box. That’s a small quibble for a grate that performs this well. The 599 reviews averaging 4.7 stars confirm that most users are very satisfied with the build quality and cooking performance. For Weber kettle owners who want a serious upgrade, this is an excellent choice.

Who this grate is best for

Weber 22 or 22.5-inch kettle owners (Original Kettle, Master-Touch, Performer, Bar-B-Kettle) will find this grate a perfect fit that delivers professional searing performance. It’s also ideal for those who want GBS accessory compatibility.

Who should look elsewhere

If you own a Weber gas grill or a non-kettle charcoal grill, this grate won’t fit. If weight is a major concern, the 20.3-pound total may be cumbersome for some users to handle.

7. Broil King 11241 Grid-Baron Cast Iron Cooking Grate – Best Reversible Design

I tested the Broil King Grid-Baron on a Broil King Baron 500 and the fit was exact. The reversible design is genuinely useful: the pointed side creates professional-looking sear marks on steaks, while the concave side channels juices away from the food for more delicate items like fish or chicken. I cooked both ribeye and salmon on the same grate during testing, and both came out beautifully.

The porcelain coating over the cast iron is a nice touch. It provides a smoother cooking surface that releases food more easily than raw cast iron, while still delivering the heat retention cast iron is known for. After a 15-minute preheat, the surface was hot enough to give a steak those restaurant-style dark grill lines within 90 seconds per side.

Build quality is solid. The cast iron feels substantial, and the porcelain finish was uniform without any chips or rough spots on the unit I tested. The reversible profile is genuinely different from other grates on this list, giving you two distinct cooking surfaces in one product. It’s the kind of feature you didn’t know you needed until you tried it.

The main concern is occasional breakage during shipping, which a few reviewers reported. The porcelain coating can crack if the grate takes a hard impact. Inspecting the package on arrival and reporting any damage immediately is the best approach. Once installed, the Grid-Baron performs reliably and is a direct OEM fit for Broil King Baron 300/400/500 series (2013+) and Crown 300/400/500 series (2012+).

Who this grate is best for

Broil King Baron and Crown series owners who want a genuine OEM replacement with the versatility of a reversible design will appreciate this grate. The dual-sided profile is also great for grillers who cook a wide variety of foods.

Who should look elsewhere

If you don’t own a compatible Broil King model, this grate won’t fit your grill. If you’re looking for full-coverage replacement grates, note that these are individual sections rather than a complete set.

8. Antree 7525 Porcelain Enameled Grates – Best Budget for Weber Spirit

I dropped these Antree 7525 grates into a Weber Spirit E-310 (2007-2012 era) and they snapped into place without any tools. The porcelain-enamel finish looked identical to the OEM grates they replaced, and after a thorough preheat, I cooked burgers that came out with classic Weber sear lines.

The price-to-performance ratio is what makes these grates stand out. They cost roughly half of what Weber OEM charges, and the cooking performance is nearly indistinguishable for the first few years of use. The porcelain finish is smooth and releases food well when properly preheated. Heat retention matches OEM specs, and I didn’t notice any difference in cooking times or sear mark quality.

The compatibility list is impressive. These grates fit Weber Spirit 300 series (E310/E320 2007-2012, Spirit S310/S320/SP-330), Spirit 700, and Genesis Silver/Gold/Platinum series from 2005 and earlier, plus Genesis 1000-3500 models. For owners of older Weber grills looking for an affordable refresh, this is one of the best values on the market.

The trade-off is longevity. Several long-term reviewers noted that the porcelain finish can start to peel or rust after about four years, compared to nine or more years from genuine Weber parts. The 12-month durability guarantee from Antree provides some protection, and the company’s customer service is known for sending free replacements when issues arise. For budget-conscious grillers who don’t mind replacing grates more frequently, this is a smart buy.

Who this grate is best for

Weber Spirit 300, Spirit 700, or older Genesis Silver/Gold owners looking for an affordable replacement will find these grates a perfect fit at a fraction of OEM cost. They’re also great for reviving older grills that have been in storage.

Who should look elsewhere

If you want maximum lifespan and don’t mind paying more, the Weber OEM grates are a better long-term investment. Also, these won’t fit the newer Spirit II models or Genesis II grills.

Buying Guide: How to Choose the Best Cast Iron Grill Grates

Choosing the best cast iron grill grates for your setup comes down to three main factors: compatibility with your grill model, the type of cast iron (raw or porcelain-enameled), and how much maintenance you’re willing to do. Below, I’ll walk through each factor based on what I learned testing these eight products.

Cast Iron vs Stainless Steel vs Porcelain-Coated

Cast iron grill grates deliver the best heat retention and create the most defined sear marks because the iron absorbs and stores thermal energy. Porcelain-enameled cast iron adds a glass-based coating that seals the iron, making cleanup easier and providing some rust protection, but the coating can chip over time. Stainless steel grates are the easiest to maintain but don’t retain heat nearly as well, which is why many serious grillers upgrade to cast iron.

If you want the best cooking performance and don’t mind some maintenance, raw cast iron (like the QuliMetal option) is the way to go. If you prefer easier cleanup and don’t grill as frequently, porcelain-enameled cast iron (Weber, Broil King, Antree) is a better fit. Stainless steel grates remain a fine choice for casual grilling where sear marks aren’t a priority.

Sizing and Compatibility by Grill Brand

Getting the right size is critical. Most grill brands use specific grate dimensions for each model series, and aftermarket grates only fit certain lines. For Weber Genesis 300 (2007-2016), the OEM part 7524 fits perfectly. For Genesis II 300 (2017+), QuliMetal’s 18.75-inch set is a popular aftermarket choice. Chargriller owners should match their specific model number against the compatibility list before ordering.

When in doubt, measure your existing grates before purchasing. Most are between 17 and 19 inches long, but the width and number of grates vary by grill series. The products above include specific compatibility information to help you match your grill model.

Seasoning and Maintenance Tips

Raw cast iron grill grates need to be seasoned before first use. After washing and drying the grates, apply a thin layer of high-smoke-point oil (flaxseed, vegetable, or canola) and heat the grates until the oil smokes and bonds to the iron. Repeat this process 2-3 times for a strong initial seasoning layer.

For routine cleaning, avoid soaking cast iron in water. Instead, preheat the grates on high for 10-15 minutes to burn off residue, then brush with a grill brush while still hot. After cleaning, wipe a thin coat of oil across the surface to prevent rust. Porcelain-enameled grates are more forgiving and can be cleaned with warm water and a soft brush, but avoid thermal shock (don’t pour cold water on hot porcelain).

Heat Retention and Cooking Performance

The main reason to upgrade to cast iron is heat retention. Heavy cast iron stores thermal energy and releases it steadily, which means food sears aggressively the moment it touches the surface. This produces the Maillard reaction that creates deep browning and complex flavors. If you cook thick steaks, chops, or burgers frequently, cast iron is a clear upgrade over stainless steel.

Weight is a useful proxy for heat retention. Grates in the 10-16 pound range perform well for most home grilling, while heavier grates (16+ pounds) are ideal for high-heat searing and consistent performance across long cooks.
