Full-Size Griddle Inserts for Weber Genesis 300 Series - Flat Top

In this review the DELSbbq full-size griddle insert is judged on fit, heat performance and versatility. It is aimed at owners of Weber Genesis 300 series grills who want to convert their gas grill into a flat-top quickly; the single biggest reason to buy is that it replaces full-size grates with a large, ceramic nonstick surface that cooks evenly and handles everything from pancakes to smash burgers. The plate ships with a handle and gloves for safe handling and its 25 in by 19.4 in footprint mirrors the factory grate area for a direct swap.

Key Features

• Exact Fit: Designed as a replacement for full-size Weber Genesis 300 series grates and compatible with many factory grate models, so installation is a direct swap that takes seconds.
• Large Cooking Surface: The 25 in x 19.4 in plate provides room to cook multiple items at once for family meals or small gatherings, reducing batch cooking time.
• Ceramic Nonstick Finish: The nonstick surface reduces sticking and makes cleanup easier while still allowing high-heat searing when needed.
• Handle and Gloves Included: The included handle and gloves make it safer to lift and maneuver the hot griddle without awkward tools.
• Uses Existing Heat Plates: You keep the flavorizer bars in place so the griddle benefits from even heat spreading and protection for the burners, which helps the plate heat faster and last longer.

Who It's For

This griddle is best for owners of Weber Genesis E-310, S-310, E-320, S-320, E-330, S-330 and the EP/CEP 310-330 range from the 2007-2016 model years who want to expand their outdoor cooking options without replacing the whole grill. It is well suited to home cooks who want a flat-top for eggs, pancakes, quesadillas and seared meats while keeping the grill as their primary outdoor cooker.

If you own a Genesis II 300 or Genesis II LX 300 series grill, or a different grill family, this insert is not compatible and you should look for a model specific to that series. Also, those seeking a lightweight portable griddle for camping or small tailgates should consider smaller standalone griddles instead of this full-size replacement.

Pros & Cons

Pros

• Fits the Genesis 300 series precisely, making installation quick and simple.
• Ceramic nonstick surface cooks cleanly and is easy to wipe down after use.
• Large surface handles multiple items and sears meat with good heat distribution.

Cons

• The griddle is fairly heavy, which can make handling awkward without the included handle and gloves.

Our Verdict
