GLOWYE Full-Size Carbon Steel Griddle Insert for Weber Spirit 300 Series — 22.7×17.3 in Heavy-Duty Flat-Top

The GLOWYE full-size carbon steel griddle insert transforms compatible Weber Spirit and Genesis gas grills into a flat-top cooking surface for pancakes, bacon, steaks and stir-fries.

This heavy-duty, rust-resistant griddle is engineered as a direct-fit replacement for many Weber Spirit I & II 300 series models and a wide range of Genesis and other Weber grills listed by GLOWYE. Built from thick carbon steel with dual handles, raised sidewalls and a full-width grease tray, it gives you the even heat and splash protection of a dedicated flat-top without permanent modification to your grill. Note compatibility details before ordering — it is not intended for Weber Spirit 300 (2025 models).

Will this griddle fit my Weber Spirit 300 or Genesis grill?

The GLOWYE insert is sized to replace the Weber 6787 full-size griddle for many Spirit I & II 300 series models and several Genesis models from 2000 onward. Measure your existing cooking area against the listed dimensions to confirm fit.

• Overall size: 22.7" W x 17.3" D x 1.57" H — compare to your grill's cooking surface
• Compatible: Spirit E310/E320/S310/S320, Spirit II E-310/S-310 and many Genesis series
• Not compatible: Weber Spirit 300 models produced in 2025 (verify model number)

How does the griddle perform for everyday cooking?

This flat-top offers an even searing surface and quick temperature recovery because of the thick carbon steel build. Food releases well when properly seasoned, and the high sidewalls help contain grease and splatter for clean, safe cooking.

• Heat tolerance up to approximately 550°F for searing and high-heat tasks
• Raised sidewalls reduce grease spatter and keep food on the plate
• Full-width grease tray channels fat away from the cooking surface for easier cleanup

What care and preparation does the carbon steel griddle require?

Carbon steel performs best when it’s seasoned before first use and cared for after each cook. Avoid abrasive cleaners or dishwashers; instead use light soap initially, then maintain seasoning with oil and gentle wiping.

• Initial seasoning: wash, apply thin oil layer, heat until smoking, cool, repeat 2–3 times
• Daily cleaning: scrape residue, wipe with warm water and mild soap if needed, dry and oil lightly
• Do not use metal scouring pads or dishwasher — protect the non-stick seasoning

How does the design make handling and cleaning easier?

Dual full-width handles let you lift and reposition the griddle safely when cool, and the raised lip plus grease tray keep mess contained. The thick carbon steel resists warping so the plate remains flat over repeated high-heat cooks.

• Dual handles provide secure grips for safe removal and placement
• High sidewalls prevent splashes and keep food from sliding off
• Grease tray simplifies fat collection and shortens cleaning time
