Weber Rust-Resistant Outdoor Griddle Insert for Spirit and Searwood

In this review the Weber Rust-Resistant Outdoor Griddle Insert is presented as a practical upgrade for owners who want to expand what they can cook on their existing grill. The bottom line: if you have a compatible Spirit 4-burner or Spirit/Spirit II 3-burner grill from the stated production years, or a Searwood pellet grill, this insert turns the entire grilling surface into a full-sized flat top that is pre-seasoned and ready to use, making it ideal for large breakfasts and versatile outdoor searing. The most convincing reason to buy is its durable carbon steel construction, which delivers consistent edge-to-edge heat and avoids the warping common to thinner griddle plates.

Key Features

• Full-size conversion: Converts the grill's entire cooking surface to a single griddle so you can cook multiple items at once for family meals or parties.
• Compatibility: Fits Spirit 4-burner gas grills made since 2025, Spirit and Spirit II 3-burner grills made from 2016-2024, and Searwood pellet grills for straightforward installation.
• Pre-seasoned finish: Ships pre-seasoned so the insert is ready to use out of the box without additional break-in time.
• Grease management: Designed to work with the grill's existing grease collection system and has rimmed edges to reduce spills and keep food and oil contained.
• Even heat retention: Made from carbon steel that holds and spreads heat evenly for consistent browning, sauteing, and searing.
• Durable build: Thick material resists warping compared with thinner griddle surfaces and stands up to frequent outdoor use.

Who It's For

The Weber griddle insert is best for owners of compatible Weber Spirit and Searwood grills who want to expand from classic direct-flame grilling to a flat-top experience for pancakes, eggs, fajitas, stir fries, and party breakfasts. It suits people who value a large, uninterrupted cooking surface and expect durable, even heating from a heavy carbon steel plate.

Those who should look elsewhere include owners of older or incompatible grill models and users who need a portable tabletop griddle; this insert is designed to integrate into specific grill cavities rather than serve as a standalone appliance.

Pros & Cons
