Weber Genesis II Griddle Insert — Porcelain-Enameled Cast Iron, Double-Sided Flat & Ridged (Fits 3/4/6-Burner)

The Weber Genesis II Griddle Insert is a heavy-duty, double-sided porcelain-enameled cast iron cooking plate that converts one grate on Genesis II and II LX 3-, 4-, or 6-burner grills into a versatile flat and ridged griddle surface.

Turn your Weber Genesis II into a multi-use outdoor cooktop that sears steaks, sautés vegetables, and pancakes with even heat. This insert replaces a single grate, offering a flat smooth side for eggs and crepes and a ridged side for grill marks and drippings. Built from porcelain-enameled cast iron, it holds heat well and resists sticking while fitting neatly into the grill’s existing cookbox. Note: it does not fit 2022 Genesis gas grills and is intended to be hand-washed for best care.

How does the double-sided design improve my grilling options?

The two different cooking surfaces let you switch between flat-top techniques and traditional grilling textures without swapping pans. Use the smooth face for delicate items like fish and breakfast foods; flip to the ridged side for steaks, burgers, or vegetables that benefit from char lines and quicker fat drainage. The insert nests into one grate position, so you can mix griddle cooking with open grate grilling on the rest of the grill.

• Flat side: ideal for eggs, pancakes, stir-fries, and sauces.
• Ridged side: delivers sear marks and channels grease away from food.
• Single-grate replacement: preserves remaining grill space for other items.

What materials and performance can I expect from this cast iron griddle?

Constructed from heavy-duty cast iron with a porcelain-enameled finish, the insert combines cast iron’s heat retention with porcelain’s easier cleanup and sticking resistance. The mass of the metal evens temperature across the surface, minimizing hot spots and helping maintain steady searing temperatures. Porcelain enamel also protects the cast iron from rusting when properly cleaned and dried.

• Porcelain-enameled cast iron for stronger heat retention and easier release.
• Even heat distribution to improve searing and consistent cooking.
• Durable construction built to endure repeated outdoor use.

How does grease management work with the insert?

The ridged side is angled to direct grease toward a built-in drainage channel that funnels liquids into the grill’s grease reservoir. That helps reduce flare-ups under the griddle and keeps excess fat out of direct contact with the burners. The design integrates with the Genesis II flavorizer bars and cookbox so runoff is collected and filtered where it belongs.

• Angled cooking surface channels grease to a reservoir.
• Drainage reduces flare-ups and smoke from pooled fats.
• Works with existing flavorizer bars to route grease into the cookbox catchment.

What care and compatibility details should I know before buying?

This insert replaces one grate on Genesis II and II LX 3-, 4-, and 6-burner models (excluding 2022 Genesis grills). To preserve the porcelain finish and prevent rust, hand wash the griddle after use, dry it completely, and store it in a dry location. Frequent seasoning is not required like raw cast iron, but occasional light oiling after cleaning will maintain the surface.

• Compatible with Genesis II and II LX 3-, 4-, and 6-burner grills (not 2022 Genesis).
• Hand wash only; dry fully and store indoors when not in use.
• Occasional oiling keeps the porcelain-enameled surface performing well.

Who this is for: Home grillers who want to expand a Genesis II grill’s capabilities without adding separate cookware will value this griddle insert. It suits weekend hosts who flip between breakfast and burgers, outdoor chefs needing a stable searing surface, and families seeking a durable, integrated accessory that simplifies grease control. If you have a compatible Genesis II or II LX model and prefer a low-profile, heavy-duty griddle that slips into place and performs consistently, this Weber porcelain-enameled cast iron insert is a practical upgrade.
