Weber Rust-Resistant Outdoor Griddle Insert for Genesis and Summit

Bottom line: This is a hands-on review of the Weber Rust-Resistant Outdoor Griddle Insert and who will get the most from it. In this review the griddle insert stands out for converting a compatible Weber grill into a full cooking surface quickly, making it ideal for households that want pancakes, eggs, fajitas or large party breakfasts cooked outdoors with even heat. The largest reason to buy is its full-size carbon steel construction and pre-seasoned surface that lets users start griddling right away while relying on the grill's burners for consistent, edge-to-edge heat.

Key Features

• Full-size conversion: The insert converts the grill's entire cooking surface to a continuous griddle so you can cook multiple items at once for family meals or gatherings.
• Compatibility: Designed specifically to fit Genesis and Genesis II 300 Series gas grills from 2016 onward and Summit gas grills from 2024 onward, ensuring a secure, integrated fit.
• Durable carbon steel: Thick material resists warping and helps retain even heat across the surface for reliable sauteing, browning, or searing.
• Pre-seasoned and ready: The griddle ships pre-seasoned so you can start cooking immediately without lengthy break-in procedures.
• Mess-management design: Rimmed edges and an optimized grease management channel integrate with the grill's collection system to reduce spills and cleanup.
• Storage protection: The griddle works with an optional storage bag to protect the surface when not in use and limit exposure to the elements.

Who It's For

This griddle insert is best for owners of compatible Weber Genesis or Summit gas grills who want to expand their outdoor cooking repertoire beyond direct-grill searing. It suits families that cook large breakfasts or host backyard parties where the ability to run eggs and pancakes alongside seared vegetables or fajitas on one flat surface is valuable.

Those who should look elsewhere include people with non-compatible grill models or buyers who need a lightweight, portable tabletop griddle; this insert is engineered to integrate into specific full-size grills and relies on their built-in burners rather than being a standalone portable unit.

Pros & Cons

Pros

• Well-made carbon steel construction gives consistent, even heat and resists warping compared with thinner griddles.
• Pre-seasoned surface saves time and lets users start cooking immediately.
• Design integrates with grill grease management and has rimmed edges to keep food and oil contained.
• Customers praise fit and overall cooking ability, including handling large party breakfasts.

Cons

• Only fits Genesis and Genesis II 300 Series (2016+) and Summit (2024+), so it is not universal.
• Storage bag is sold separately, so extra protection requires an additional purchase.
