KATEEDY Cast Iron Full-Size Griddle Insert for Weber Genesis 300 Series — 4mm Heavy-Duty, Rear Grease Slot

The KATEEDY full-size cast iron griddle inserts cleanly into Weber Genesis 300-series grills to give you a durable, high-heat flat cooking surface for searing, frying, and breakfast fare.

This heavy-duty griddle is built to replace or upgrade the factory plate on Genesis E310, E320, E330 and S-series grills, plus select Pit Boss models. Constructed from 4 mm cast iron, it delivers quick, even heat and a surface that develops excellent seasoning over time. Upgraded details such as a rear grease slot, polished edges, and removable side handles make it easier to use, transfer, and maintain while fitting existing Weber grease-management systems.

How will this griddle change my weekend cookouts?

Switching to a full-size cast iron griddle widens the menu beyond burgers—think pancakes, stir-fries, quesadillas, and perfectly crisped vegetables. The thick iron holds heat so foods brown uniformly and stay hot across the surface, reducing cold spots and improving sear. You’ll also notice fewer flare-ups thanks to the integrated grease channel.

• Generous flat surface for multiple foods at once
• 4 mm cast iron for stable, retained heat
• Rear grease slot routes drippings into grill system to minimize flames
• Polished edges and detachable handles simplify handling and cleaning

Will it fit my Weber Genesis 300 series or replace OEM parts?

This insert is designed specifically to fit the Genesis 300 series including E-310, E-320, E-330 and S-310, S-320, S-330 lines, and it corresponds to several OEM part numbers commonly used as replacements. It also lists compatibility with some Pit Boss PB700 models. Measure your current cooking plate or compare part numbers if you’re unsure.

• Direct fit for Genesis 300-series grills (E and S models)
• Compatible with replacement part references like 7524, 7566, and related numbers
• Works with grill grease management systems via the rear grease slot
• Detachable handles help align and lift the insert safely

How do I care for and maintain this cast iron griddle?

Cast iron benefits from a simple routine: season, clean gently, and reapply oil as needed. Avoid harsh detergents; wipe or rinse and dry immediately to prevent rust. The griddle’s polished edges and thicker plate reduce warping and make maintenance straightforward after heavy use.

• Season with neutral oil after each deep clean to preserve nonstick qualities
• Hand wash with warm water or scrub with a brush; dry thoroughly
• Use the detachable handles to move the griddle without touching hot iron
• Store in a dry place; re-oil occasionally to prevent oxidation

What safety and usability features does it include?

The KATEEDY griddle focuses on secure handling and cleaner cooking. Removable side handles let you lift the heavy plate without grabbing hot metal edges, while the rear grease trough helps channel drips away from burners to reduce flare-ups. Rounded, polished edges protect hands and cookware from snags.

• Detachable handles reduce burn risk when transferring the griddle
• Grease channel integrates with the grill’s drip system to limit splatter
• Edge polishing lowers the chance of cuts or damage to accessories
• Thicker construction resists bending under high heat and weight

Who is this for: The KATEEDY full-size griddle insert is aimed at grill owners who want to expand their outdoor cooking repertoire with a rugged cast iron surface. It’s ideal for owners of Weber Genesis 300-series grills and compatible Pit Boss models who need a direct-fit replacement or an upgrade that improves heat retention, safety, and grease management without complex modification.
