Cast Iron Two-Zone Grill Insert for Kamado (Model DC20GRID) — Medium

The Kamado Cast Iron Two-Zone Grill Insert for Kamado (medium) is a heavy-duty cast iron cooking grate engineered to create separate high- and low-heat zones in medium-sized Kamado ceramic grills. The insert divides the cooking surface so you can sear directly over high heat while maintaining an adjacent area for indirect or lower-temperature cooking. Its thick cast iron construction stores and distributes heat evenly to support consistent searing, browning and roasting results on a range of foods.

Advantages

This cast iron insert provides durable, long-lasting performance and excellent heat retention, enabling strong sear marks and steady temperatures for indirect cooking. By offering two distinct cooking zones in a single unit, it increases the versatility of a Kamado grill without the need for additional accessories. The solid cast iron surface also promotes even heat transfer and contributes to reliable roasting and grilling outcomes.

Suitable for

• Direct high-heat searing of steaks, chops and poultry
• Indirect slow-roasting of larger cuts and whole birds
• Simultaneous grilling and finishing at different temperatures
• Maintaining stable heat for smoked or low-and-slow preparations

Key specifications

• Material: cast iron for high heat retention and durability
• Configuration: two-zone design with separate high-heat and low-heat areas
• Compatibility: designed for medium-sized Kamado ceramic grills
• Functionality: suitable for direct searing, indirect cooking and roasting
• Surface finish: heavy-duty seasoned cast iron surface for improved searing

How to use

Install the insert into the grill so that the high-heat side aligns over the charcoal or heat source and the low-heat side is positioned away from direct coals. Preheat the grill with the insert in place to allow the cast iron to reach an even cooking temperature. Use the high-heat zone for quick searing and move items to the lower-heat zone to finish cooking or to keep warm. Clean and maintain the insert according to cast iron care practices: avoid harsh detergents, dry thoroughly after cleaning and lightly oil the surface to preserve seasoning.

Usage recommendations

For best results, preheat the insert gradually to minimize thermal shock and maintain the seasoned surface. Use a two-zone approach: sear at high temperature, then finish using the indirect zone to control internal doneness without burning the exterior. Regularly re-season the cast iron after cleaning to sustain non-stick properties and prevent rust.
