Weber Genesis 300 Series Griddle Insert Review Rust-Resistant Grill Upgrade

Description

A Versatile Addition: Weber Rust-Resistant Griddle Insert, Genesis 300 Series

Ease of Conversion and Compatibility
I was intrigued by the Weber Rust-Resistant Griddle Insert for the Genesis 300 Series, which promised to transform my existing grill into a full-scale flat-top griddle. The compatibility with the three-burner Genesis models from 2016 and later, as well as Summit models from 2024 onward, made it a convenient choice for my outdoor cooking setup. Installing the griddle was straightforward, and it fit securely without any adjustments needed. The rectangular shape and precise dimensions (21.65”L x 3.15”W x 29”Th) ensured a snug fit, giving me confidence in its stability during use.

Switching from a traditional grill to a griddle opens up so many culinary possibilities. From brunch classics like pancakes and eggs to stir-fried veggies or smash burgers, this insert adds versatility to any cookout. However, I did notice its weight—at nearly 30 pounds, it’s not light, which speaks to its durability but may be cumbersome for some users during setup.

Material Quality and Rust Resistance
One of the standout features of this griddle insert is its carbon steel construction, which is specifically designed to resist rust. The case-hardened surface, achieved through extreme heat and pressure, adds an extra layer of protection against moisture buildup. I left it outside (albeit covered) after a rainy evening, and true to its claims, there wasn’t a hint of rust the next day.

Another noteworthy point is the pre-seasoned surface, which combines food-safe oils to create a non-stick-like effect right from the box. I didn’t have to go through the hassle of seasoning it myself. Cooking on the griddle was smooth, with minimal sticking, even when I made cheese-heavy quesadillas. However, the lack of a true non-stick coating means there’s a learning curve in managing heat and oil to avoid food residue.

Cooking Performance and Heat Retention
The griddle’s thick carbon steel material does an excellent job of retaining heat, ensuring even cooking across its surface. This was particularly evident when I cooked multiple pancakes and noticed they browned evenly, even at the edges. The heat distribution is superior to thinner griddle options, which often suffer from hot spots.

What I loved most was the warp-resistant design, which held its shape perfectly during high-heat cooking. I’ve dealt with cheaper griddles that warp over time, and it’s frustrating to see your eggs sliding to one side. With this griddle, that problem was non-existent. The rear grease slot is another thoughtful addition, channeling grease into the grill’s grease management system and minimizing mess. Cleanup was manageable, though not effortless, since the griddle isn’t dishwasher-safe.

Key Benefits

• Durable carbon steel construction that resists rust and warping.
• Even heat distribution for consistent cooking results.
• Pre-seasoned surface eliminates the need for initial seasoning.
• Fits seamlessly into compatible Weber grills.

Shortcomings

• Hefty weight makes it less portable and harder to handle.
• Not dishwasher-safe, requiring manual cleaning.
• Surface maintenance is needed to avoid food sticking over time.

Safe for Metal Tools
Unlike griddles with delicate coatings, this one is safe for use with metal tools, which is a huge relief. I used a metal spatula to flip burgers and scrape off caramelized bits, and there wasn’t a single scratch to show for it. This durability adds to its long-term value, especially for those who prefer robust tools in their grilling arsenal.

Direct Competitors
Comparing this griddle to Blackstone flat-top grills, I noticed a few distinctions. While Blackstone offers a standalone griddle experience with a larger cooking surface, the Weber griddle insert excels in its seamless integration with existing grills. Blackstone products often come with a non-stick coating, which can wear out over time, whereas the Weber’s carbon steel surface is built for longevity.

Another competitor, the Cuisinart CGG-888, comes with a circular design that’s suitable for smaller spaces but lacks the same compatibility and robust heat retention. While the Cuisinart is more portable, it doesn’t provide the same comprehensive grilling-to-griddling transformation. The Weber griddle’s warp-resistant build and compatibility tip the scales in its favor for users seeking a high-quality upgrade for their Genesis grill.

Quality for Price
This griddle insert offers great value for its premium features, especially for those who already own a compatible Weber grill. Its durable construction, rust resistance, and heat retention justify the investment, even if it’s pricier than some standalone griddles. While you could opt for cheaper alternatives, they often lack the thoughtful design and compatibility that make this product so appealing.

For anyone serious about grilling and looking to expand their outdoor cooking repertoire, this griddle is a worthwhile addition. It’s not flawless, but its strengths far outweigh its minor inconveniences, making it a reliable choice for both casual cooks and grilling enthusiasts.
