Weber Griddle Insert for Genesis 400 Series — Carbon‑Steel, Rust‑Resistant, Pre‑seasoned

The Weber Rust‑Resistant Griddle Insert turns a compatible Genesis or Genesis II 400 Series grill into a full‑size outdoor griddle in seconds.

If you already own a Genesis or Genesis II 400 Series gas grill (model year 2016 or newer), this carbon‑steel griddle insert gives you a versatile flat top without buying another appliance. Engineered to replace the grill grate across the entire cooking area, it uses your grill’s burners for even, edge‑to‑edge heat and adds a rimmed, grease‑managed surface for everything from breakfast staples to seared steaks.

How quickly can I switch from grill to griddle?

Changing to griddle mode is a simple swap: remove the grill grates and drop the insert into the Genesis 400 Series frame. Because it’s designed specifically for those models, it seats securely and lines up with the grill’s grease management and burners so you can start cooking right away.

• Fits Genesis and Genesis II 400 Series (2016 and newer)
• Installs in seconds—no tools required
• Pre‑seasoned surface ready for immediate use
• Interfaces with the grill’s grease collection system

What cooking results and techniques can I expect?

The heavy carbon steel surface conducts and holds heat uniformly, making it ideal for searing, sautéing, and browning as well as delicate tasks like flipping pancakes. Because heat spreads across the full plate, food cooks consistently from one side to the other so the last batch looks and tastes like the first.

• Even, edge‑to‑edge heat for reliable searing and browning
• Large flat surface for pancakes, eggs, fajitas, stir‑fry and more
• Rimmed edges keep oil and ingredients on the griddle
• Durable thickness resists warping under high heat

How does the griddle handle grease and cleanup?

The insert integrates with your Genesis grill’s grease management to channel drips away from the main cooking area and into the existing collection system. Its rimmed border and sloped surface help contain oils and make scraping, wiping, and wiping with paper or a grill scraper faster and cleaner than an open‑flame pan.

• Grease management compatible with Genesis grease trays
• Rimmed design prevents spills and holds liquids on the plate
• Pre‑seasoned surface eases initial cleanup and reduces sticking
• Thick carbon steel simplifies scraping and maintenance

How should I store and protect the griddle when not in use?

To keep the finish and seasoning in good shape, dry the griddle after cleaning and store it indoors or in a protective Weber storage bag. The bag (sold separately) shields the metal from moisture and elements that can accelerate rust, extending the life and performance of the griddle insert.

• Dry thoroughly after each use to avoid surface corrosion
• Use a Weber storage bag for outdoor storage (sold separately)
• Occasional reseasoning maintains a nonstick cooking layer
• Thick carbon steel construction reduces warping over time

Who is this for? The Weber Rust‑Resistant Griddle Insert is made for grill owners who want to expand their outdoor cooking options without buying a separate appliance. If you own a Genesis or Genesis II 400 Series (2016 or newer) and enjoy breakfasts, stir‑fries, or restaurant‑style seared dishes outdoors, this insert delivers a large, restaurant‑capable griddle surface that integrates with your existing grill’s burners and grease system. It’s also suited to anyone who values durable construction, quick installation, and easier cleanup while preserving storage convenience with an optional protective bag.
