10 Best Weber Grill Inserts 2025 in the United States

The Utheer Full Size Grill Griddle Insert is a stainless steel flat top griddle designed to fit a wide range of Weber Genesis II 300 and LX 300 series grills from 2017 onward. It offers a large cooking surface of 489 square inches, providing ample space to cook breakfast favorites like eggs and pancakes, or grill lunch and dinner items such as steaks and vegetables. Since it sits closer to the grill's fire source after installation (which involves removing grill grates and flavorizer bars), it heats up efficiently and evenly, contributing to proper cooking of your food.

Constructed from durable stainless steel, this griddle is built to last and is dishwasher safe, simplifying cleanup compared to many traditional cast iron or nonstick options. It does not have a nonstick coating, so seasoning or oiling before use is recommended to prevent sticking. Installation is straightforward, allowing easy swapping in and out based on your cooking needs.

This griddle insert is an excellent choice for backyard barbecues, tailgating, or camping, expanding the versatility of your Weber grill without requiring a separate appliance. It is specifically designed for newer Weber Genesis II models and will not fit older models from 2007 to 2016. While some might miss the convenience of a nonstick surface, the stainless steel construction provides strong durability and good heat distribution. If you want a sturdy, roomy griddle insert compatible with your Weber Genesis II grill and don’t mind seasoning it before use, this product offers a great balance of performance and ease of maintenance.

The Weber Rust-Resistant Griddle Insert for the Genesis 300 Series is a versatile addition for those looking to expand their grill's capabilities. Constructed from durable carbon steel, this griddle insert is rust-resistant, ensuring longevity and consistent performance. Its pre-seasoned surface offers a natural non-stick experience right out of the box, eliminating the need for additional waxing or oiling before use. The griddle's design allows it to fit perfectly with 3-burner Genesis 2016+ and Summit 2024+ models, making it highly compatible with modern Weber grills.

One of its standout features is the even heat distribution across the entire cooking surface, which helps in cooking food uniformly. Additionally, the thick material helps in preventing warping, a common issue with thinner griddle surfaces. The rear grease slot is a thoughtful inclusion, directing grease into the grill’s grease management system and making cleanup easier. However, it is worth noting that this griddle is not dishwasher safe, which might be a drawback for those looking for minimal maintenance.

The absence of a nonstick coating means you can freely use metal tools without worrying about damaging the surface, but it might require more effort to clean manually. Weighing in at 30.6 pounds, it's relatively heavy, which can be a consideration if you frequently move or store your grill accessories. If you own a compatible Weber grill and seek a robust, easy-to-use griddle insert that ensures even cooking and durability, the Weber Rust-Resistant Griddle Insert is a solid choice. Just be prepared for a bit of manual cleaning post-cooking.

This full-size griddle insert is designed specifically for Weber Genesis II 400 Series grills, making it a great choice if you want to expand your cooking options beyond traditional grilling. Made from carbon steel with a nonstick coating, it heats up quickly due to its direct placement close to the fire, which helps cook food evenly and efficiently. Its large cooking surface (about 18.75 by 32.6 inches) offers plenty of room to prepare various foods like steaks, vegetables, eggs, and pancakes all at once. The griddle’s rectangular shape matches well with the original Weber grates, so swapping between grilling and griddling is simple and quick. The included silicone gloves are a nice bonus, providing safe handling even when the griddle is hot.

One downside is that it’s not dishwasher safe, so cleaning requires some effort—though the nonstick surface does make this easier than plain steel. It’s important to remove the heat plates underneath the griddle for optimal heating, which may be a minor extra step. This insert is well suited for Weber Genesis II 400 owners who want versatility and good heat distribution for a variety of dishes, though users should be prepared for manual cleaning and ensure their grill model matches the compatibility list carefully before purchasing.
