9 Best Griddle Inserts for Gas Grill 2026

This workhorse of a griddle delivers unmatched value with its reversible cast iron construction, combining a flat griddle surface and raised ribbed grill in one rugged piece. Crafted in the USA and pre-seasoned with just oil and iron, it’s a PFAS-free powerhouse that excels on gas grills, stoves, and even open flames—perfect for campers and weekend warriors who demand versatility without compromise. Its compact 9.5 x 16.75-inch footprint fits neatly over two standard burners, making it ideal for smaller grills or solo cooks who still want serious searing power.

In real-world use, the Lodge shines when you need high-heat retention and even cooking—think crispy-edged pancakes, perfectly seared burgers, or caramelized veggies. The cast iron heats slowly but holds temperature like a champ, minimizing hot spots and ensuring consistent browning. However, it’s not immune to warping if heated too quickly or unevenly, so a gradual warm-up is essential. While the lack of a grease trough means drippings can pool or cause minor flare-ups, the natural non-stick seasoning improves with use, rewarding those who maintain it properly.

Compared to modern nonstick inserts, the Lodge takes more effort to clean and requires post-cook oiling to preserve its finish—but that’s the trade-off for lifetime durability and chemical-free cooking. It’s a standout choice for budget-conscious buyers and purists who appreciate traditional cookware craftsmanship. For those with larger grills or feeding bigger crowds, it may feel cramped—but for small families or two-burner setups, it’s hard to beat this level of performance at such a low entry price.

Built like a tank for extreme grilling conditions, the Unidanho 17″x13″ cast iron griddle stands out with its X-brace reinforced base, engineered to resist warping under intense heat—making it a top pick for high-temp searing and long cook sessions. This heavy-duty beast boasts exceptional heat retention and even distribution, turning your gas grill into a restaurant-grade flat-top capable of flawless steak marks and golden-brown hash browns. Its premium cast iron one-piece forge ensures longevity, appealing to users who prioritize durability over convenience.

During testing, the griddle maintained steady temperatures across the surface, even during extended use over open flame, thanks to its ultra-thick construction. The built-in grease channel efficiently funnels drippings away, reducing flare-ups and simplifying cleanup—a major win for outdoor cooks tired of messy grills. Equipped with ergonomic side handles, it’s easier to maneuver than most solid iron griddles, though still extremely heavy when hot. Still, its sheer mass means it takes time to heat up and cool down, which may frustrate users wanting quick prep times.

When stacked against lighter nonstick models like the Utheer or Uniflasy, this griddle demands more effort in handling and maintenance—but offers superior thermal performance and longevity. It’s the go-to for serious backyard chefs and tailgaters who treat grilling as a craft and don’t mind a little muscle work. While pricier than basic options, its rugged build justifies the cost for anyone seeking a long-term, high-performance upgrade over flimsier alternatives.

The Utheer 17″x13″ griddle is a compact powerhouse designed for hassle-free outdoor cooking, blending a nonstick ceramic coating with thoughtful features like removable handles and a grease groove to create a user-friendly experience. Its lightweight yet sturdy build makes it easy to transport and store—ideal for campers, RV users, and apartment dwellers with small grills who still want big flavor. The non-deform thick metal base resists warping under heat, and the polished edges ensure safety during handling.

In real-world tests, the nonstick surface performed impressively, releasing eggs, pancakes, and delicate fish without sticking—even after repeated use. The grease trough effectively captured drippings, minimizing flare-ups and keeping the cooking zone clean. Heat distribution was consistent across the surface, though it worked best when centered over two burners to avoid hot spots. While not as thermally massive as cast iron, it heats quickly and cools faster, making it perfect for short cook sessions or weekday meals. However, prolonged high-heat use may degrade the coating over time, so temperature moderation is key.

Compared to heavier cast iron options, the Utheer sacrifices some sear potential but wins in convenience and portability. It’s a smarter choice than bulkier models for those prioritizing easy cleanup and quick setup—especially families or frequent entertainers who cook diverse meals. While pricier than the Lodge, it offers a modern, low-maintenance alternative that balances performance and practicality for everyday outdoor cooking.

This value-packed 17″x13″ griddle hits the sweet spot between affordability and functionality, offering a nonstick-coated metal surface with high sidewalls and a grease groove to keep cooking contained and mess-free. Designed as a universal fit for major grill brands—including Weber, Charbroil, and Nexgrill—it’s a versatile upgrade for mid-sized grills seeking flat-top flexibility without breaking the bank. The smooth, polished edges and side handles make it safe and easy to handle, even when hot.

Performance-wise, it delivers consistent heat distribution for breakfast staples like bacon and eggs or lunchtime favorites like grilled cheese and burgers. The nonstick surface prevents sticking when properly preheated and oiled, and cleanup is a breeze with just a wipe or light scrub. Its hollowed side panels promote airflow, helping the griddle heat evenly across gas burners. That said, the coating isn’t as durable as ceramic or seasoned iron, and aggressive scraping or metal utensils can damage it over time—so care is required.

Stacked against premium picks like the Weber or Utheer cast iron models, this griddle lacks the same thermal heft or long-term durability—but for the price, it’s an excellent entry-level choice. It’s ideal for casual grillers and weekend hosts who want a no-fuss cooking experience without investing in high-end gear. While not built to last decades, it offers solid performance and wide compatibility, making it the best bang-for-buck option for those dipping their toes into griddle cooking.

For those with large grills or big appetites, the Uniflasy 25″x16″ griddle is a game-changing flat-top powerhouse, offering a massive cooking surface that transforms your outdoor setup into a full-scale backyard kitchen. Its extra-large footprint easily feeds 6–8 people at once, making it perfect for weekend brunches, tailgating feasts, or holiday cookouts where volume matters. The nonstick coating and built-in grease trough ensure food releases cleanly and drippings are managed efficiently, reducing flare-ups and simplifying post-meal cleanup.

In practice, the griddle heats evenly thanks to ventilated side panels that promote airflow across multiple burners, though optimal performance requires alignment over at least three heat zones. The polished high edges help contain splatters and make flipping easier, while the side handles (though small for the size) assist in positioning. Despite its large scale, it’s relatively lightweight for its dimensions—yet still prone to warping if heated unevenly, so gradual preheating is crucial. It’s not quite as thermally stable as cast iron, but the nonstick convenience compensates for most users.

When compared to the smaller 17″ models or the premium Weber insert, this griddle stands out for sheer capacity and value—offering restaurant-style cooking in a universal design. It’s the top pick for large-family households or frequent entertainers who need space above all else. While the nonstick layer may degrade over years of heavy use, it delivers unmatched functionality for the price, especially for those with bigger grills that go underutilized.

The Weber Full-Size Griddle Insert is the gold-standard upgrade for Weber owners, engineered to perfectly fit Spirit and Searwood series grills and convert the entire cooking surface into a seamless flat-top griddle. Made from thick carbon steel with a pre-seasoned finish, it delivers consistent, even heat—eliminating hot spots and ensuring every batch of pancakes or stir-fry cooks uniformly from edge to edge. Its rimmed design and integrated grease management route drippings directly into your grill’s catch system, minimizing mess and flare-ups.

In real-world testing, the griddle heats quickly and maintains temperature beautifully, thanks to its dense, warp-resistant construction. The surface develops a better nonstick patina over time with proper care, and the full-coverage design maximizes usable space without gaps or overhangs. It fits like a factory part—no guesswork required—making it a hassle-free, precision solution for compatible models. However, it’s not universal, so non-Weber users are out of luck, and the lack of included storage bag feels like a missed opportunity at this price point.

Compared to universal inserts, the Weber griddle offers superior fit and finish, justifying its premium cost for loyalists. It’s the ideal choice for Spirit and Searwood grill owners who want OEM-level quality and performance. While other models may offer larger sizes or lower prices, none match its seamless integration and build excellence—making it the most polished, reliable option for those already invested in the Weber ecosystem.

This monumental cast iron griddle redefines outdoor cooking with its 25″x16″ pre-seasoned surface, combining industrial-grade thickness with triple reinforced support ridges to deliver unmatched heat stability and warp resistance. As the largest cast iron option in the lineup, it’s built for serious cooks who demand restaurant-level performance—think teppanyaki-style stir-fries, all-at-once breakfast spreads, or massive burger cookouts. The nonstick seasoning improves with use, and the built-in grease trough keeps flare-ups under control while simplifying cleanup.

During extended use, the griddle demonstrated superior heat retention, maintaining consistent temps even in cool weather or during high-volume cooking. The reinforced base eliminated warping, even when exposed to direct flame for over an hour. Detachable handles make it easier to lift and store, though it’s still extremely heavy when hot—requiring two people for safe handling. While it takes longer to heat than steel models, the thermal payoff is undeniable, offering deep sear potential and even browning across the entire surface.

Against nonstick steel griddles, this Utheer model trades convenience for raw performance and longevity—it’s not for casual users, but a must-have for cast iron devotees and serious entertainers. Compared to the Uniflasy 25″ model, it offers better heat management and durability, despite a higher price. For those willing to invest in lifetime cookware with no coating to peel, this is the ultimate heavy-hitter for large-scale outdoor griddling.

The Uniflasy Nano-Ceramic Griddle stands as the best overall performer, merging cutting-edge nanoceramic coating with robust triangular support ridges to deliver scratch-resistant, nonstick cooking that lasts. Its 17″x13″ size fits most mid-sized grills, and the ventilated side panels ensure even airflow and heat distribution, preventing hot spots and warping. Designed for durability, it withstands high heat without peeling or degrading—making it ideal for daily use and diverse cooking styles, from delicate fish to seared steaks.

In testing, the surface released food effortlessly, even sticky items like eggs and cheese, with minimal oil required. The raised sidewalls and grease trough kept messes contained and flare-ups low, while the polished edges and side handles enhanced safety and portability. Heat spread evenly across the surface, thanks to the reinforced base, and cleanup was a breeze—just a quick wipe or light scrub sufficed. Unlike traditional cast iron, it requires no seasoning, making it perfect for beginners and time-crunched cooks.

When compared to the Utheer nonstick or Lodge models, this griddle offers the best balance of performance, durability, and ease of use. It’s more resilient than standard nonstick coatings and far more convenient than raw cast iron—making it the top recommendation for most users. While not the largest or cheapest, it delivers premium features and universal compatibility, justifying its position as the best all-around griddle insert for gas grills.

The Arribueno 23″x16″ griddle earns its title as the best for even heating, thanks to its thick, ceramic-coated steel construction and strategically hollowed side panels that promote uniform airflow across multiple burners. Unlike thinner models that develop hot zones, this griddle delivers consistent temperature distribution from edge to edge—making it ideal for cooking large batches of pancakes, fajitas, or smash burgers without rotating food. The healthier ceramic coating resists peeling and rust, offering a Teflon-free alternative that’s safe for high-heat cooking.

In real-world use, it heated evenly over a three-burner grill, with no noticeable hot spots—even during prolonged searing. The detachable handles made storage and cleaning easy, and the grease trough efficiently channeled drippings away, reducing smoke and mess. Its raised edges prevented splatter, and the smooth surface wiped clean effortlessly after cooking. While not as heavy as cast iron, its thick steel core resists warping better than most competitors in its class.

Compared to the Uniflasy 25″ model, it offers slightly less space but superior thermal uniformity and a sleeker profile. It’s a smarter pick than bulkier options for users who prioritize precision cooking and ease of maintenance over maximum size. For frequent outdoor chefs and health-conscious families, this griddle delivers professional-level heat control in a user-friendly, durable package—making it the top choice for those who demand reliable, even cooking every time.
