Cast iron’s heat retention supports a rapid heating cycle and a consistent, deep sear. The grate often pairs with a lifting tool included for safe handling when hot, adding convenience during installation and maintenance. Its robust construction makes it a longtime accessory for serious grillers who want reliable, restaurant-grade searing capabilities.
Char-Griller AKORN Jr. Cast Iron Grates
The AKORN Jr. model offers portable kamado performance with cast iron grates that retain heat effectively for searing. This option is noted for straightforward maintenance, an easy-dump ash pan for quick cleanup, and mobility features that make it suitable for small outdoor setups. While compact, the heat retention and distribution of cast iron help achieve a reliable crust and even cooking across a range of grill temps.
Cmanzhi 18-in Cast Iron Grate (2-Pack)
This 2-pack from Cmanzhi is designed to fit a broad family of 18-inch ceramic grills, including Kamado Joe KJ-23RHC Classic II and Classic III, as well as several large Big Green Egg models. Each grate uses matte enamel cast iron for durable heat retention and even surface heating. The package commonly includes a compatibility range that helps ensure a snug fit across multiple popular kamado setups, simplifying replacement parts logistics.
Kamado Joe Half-Moon Cast Iron Reversible Griddle
Kamado Joe’s reversible griddle combines a smooth surface with a ribbed side for versatile cooking. Cast iron’s heat retention supports steady temperatures whether you’re searing steaks or sautéing vegetables. This accessory complements the Divide & Conquer Flexible Cooking System, enabling a broader range of recipes on your 18-inch Classic Joe setup. The rugged construction provides long-lasting performance for busy outdoor kitchens.
Char-Griller AKORN Kamado Cast Iron Grates
Designed for Char-Griller’s AKORN line, these cast-iron grates are well-suited for high-heat grilling and low-and-slow cooking. The larger 20-inch cooking area expands capacity, enabling multiple burgers or larger cuts to be seared simultaneously. Features such as robust construction and heat retention help maintain consistent temperatures across long cooks, contributing to reliable, even doneness without frequent repositioning.
Buying Guide: Cast Iron Grates And Kamado Accessories
- Fit and compatibility: Check the diameter and model compatibility for your specific kamado grill. Some grates are designed for 18-inch Classic Joe setups, while others fit wider AKORNs or similar 20-inch units. If in doubt, match the product’s stated fit to your grill model.
- Heat retention and searing: Cast iron excels at heat retention, producing a strong sear and even browning. Look for enameled or matte enamel coatings that resist sticking and rust while offering long-term durability.
- Maintenance considerations: Plain cast iron may require more frequent seasoning or oiling to prevent rust, especially in humid environments. Enamel-coated varieties typically require less upkeep but can be less forgiving if the enamel chips.
- Versatility: Reversible or dual-surface grates (griddle on one side, grill surface on the other) expand cooking options. Consider whether you want to switch between searing and sautéing in one piece.
- Portability and installation: Some options include lifting tools or are designed for quick installation. For portable grills like the AKORN Jr., lighter weight and easy removal may be important.
- Durability and warranty: Replacing a grate is a common upgrade; look for durable cast iron with a robust build and a warranty that covers warping, cracking, or chipping under normal use.
- Accessory ecosystems: Kamado Joe and Char-Griller offer accessories that integrate with existing cooking systems (such as Divide & Conquer and warming racks). Consider how a grate or griddle fits within your broader cooking setup.
- Cooking goals: If you focus on high-heat searing, prioritize grates that retain heat well and provide uniform surface temperatures. For slow-smoking or indirect cooking, ensure the grate’s design promotes even air flow and stability for longer cooks.
