onlyfire Cast Iron Grill Grate Replacement for 22in Kettle - Sear

In this review the onlyfire Cast Iron Grill Grate Replacement for 22in kettle grills is judged for home cooks who want improved searing and heat retention over standard grates. The kit includes two pieces that fit Weber 22.5in style kettles: a 21.5in outer cooking grate and an 11.8in inner sear grate, and the single biggest reason to consider it is the heavy cast iron construction that holds and distributes heat for better crust formation on steaks and vegetables.

Key Features

• Two-part set: The combination of a 21.5in outer grate and an 11.8in inner sear grate allows flexible cooking setups and direct access to coals when you need more heat.
• Cast iron construction: Thick cast iron stores and radiates heat evenly so foods develop consistent sear marks and retain temperature during searing.
• Inner sear grate with handles: The raised side handles on the inner insert make it easy to lift the center for adding charcoal without removing the outer grate.
• Designed for 22.5in kettles: Fits Original Kettle and Performer Premium 22.5in charcoal grills, so swapping in the replacement is straightforward for those models.
• Easy cleanup: The smooth cast iron surface wipes clean after cooking and benefits from regular seasoning to maintain a nonstick finish.

Who It's For

This replacement grate is best for avid backyard grillers and steak lovers who want professional searing and improved heat retention from a heavy cast iron surface. It suits owners of 22.5in original and performer style kettle charcoal grills who value robust construction and the ability to lift the inner section to add coals.

Less suitable users are those who prefer lightweight, rust-proof materials without regular seasoning care, or anyone who needs an exact match for a kettle with nonstandard grate dimensions. If corrosion resistance without maintenance is your priority, a different material may be preferable.
