Genesis II Grates and Griddle Set for Genesis II 300 Series - Dual

In this review the Genesis II Grates and Griddle set is judged as a practical upgrade for owners of Genesis II 300 series grills who want versatile cooking surfaces and long-term durability. It is best for grillers who alternate between high-heat searing and breakfast or delicate foods and who value solid heat retention from heavy cast iron. The single biggest reason to buy is the dual-function design: one ridged grate for sears and one flat griddle for eggs, pancakes and vegetables, both pre-seasoned for easier release and cleaning.

Key Features

• Dual-Function Design: One cast iron grill grate and one flat griddle provide flexibility to sear steaks and cook breakfast foods without swapping accessories.
• Perfect Fit: Specifically designed to fit Genesis II E/S-310, E/S-315, E/S-325, E/S-335 and SE-335 models for a seamless replacement of original grill parts.
• Exceptional Heat Retention: Heavy-duty cast iron holds and distributes heat evenly across the cooking surface for consistent searing and browning.
• Pre-Seasoned Non-Stick Surface: The set arrives pre-seasoned for improved initial non-stick performance and easier cleanup after use.
• Durable Construction: Premium cast iron resists warping and corrosion and is designed for long-term heavy use compared with porcelain alternatives.
• Easy Maintenance: Simple care routine of preheating, oiling, hand washing and drying keeps the seasoning intact and prolongs life.

Who It's For

This set is ideal for backyard cooks who own a Genesis II 300 series grill and want one reliable, heavy-duty cooking solution that handles both high-heat searing and low-temperature foods. Users who value authentic cast iron heat and plan to maintain seasoning will appreciate the long-term performance and improved flavor development.

It is less suitable for those who prefer lightweight or fully enamel-coated grates that require minimal seasoning care, or for owners of non-compatible grill models; buyers should confirm model fit before purchasing.
