MixRBBQ Ceramic Heat Deflector Plates for Kamado 19.8-inch Half-Moon 2-Pack — Even Indirect Heat

These are two 19.8-inch half-moon ceramic heat deflector plates designed to convert large kamado grills into reliable indirect ovens for smoking, roasting, and baking.

Upgrade a Kamado Joe Big Joe (I, II, III), XL Big Green Egg, or other 24" kamado-style charcoal grill with a pair of MixRBBQ ceramic deflectors. Made from high-quality cordierite-style ceramic, the half-moon stones spread and retain heat to create an even, convection-like cooking environment. The two-piece design adds flexibility: run a single stone for combined direct and indirect grilling or pair them for full indirect cooking suitable for pizzas, whole chickens, and low-and-slow barbecue.

How do these plates change the way my kamado cooks?

MixRBBQ ceramic deflectors reduce direct flame contact and moderate hot spots so food cooks more evenly without scorching. They act as thermal mass, smoothing temperature swings and supporting steadier low temperatures for long smokes.

• Two half-moon plates allow full or half-coverage configurations.
• 19.8-inch diameter made for 24" kamado grill cooking grids.
• Ceramic construction holds heat to support long, steady cooks.
• Works with Divide & Conquer-style multi-level rack systems.

Will these fit my Kamado Joe Big Joe or Big Green Egg?

They are sized at 19.8 inches and engineered to fit Kamado Joe Big Joe series (Big Joe I, II, III) and many 24" kamado-style grills including XL Big Green Egg models. Always measure your grill or compare part numbers before buying to ensure compatibility.

• Fits Kamado Joe model numbers such as BJ24NRHC, BJ24RHC, BJ24RH, and similar.
• Compatible with many 24" charcoal grills and XL Big Green Egg cook surfaces.
• Two-piece half-moon layout pairs with standard grill racks and accessories.
• Check your grill diameter and existing deflector shape for best match.

How do I use and care for the ceramic deflectors?

Use the stones cold when inserting into a warm grill, and allow them to cool fully before removing to avoid thermal shock. Clean gently with warm water and a soft brush after they have cooled; avoid sudden temperature changes and never pour water onto hot ceramics.

• Install cold, heat the grill gradually to prevent cracking.
• Cool completely before handling or washing; hand wash only.
• Do not subject to sudden water or temperature shocks.
• Inspect packaging immediately; ceramic is fragile in transit.

What cooking results can I expect when using these deflectors?

Expect reduced flare-ups, less burned exteriors, and more uniform doneness across larger cuts of meat and baked goods. The retained heat encourages crisp crusts on pizzas and breads while supporting low-and-slow smoking with steady internal temperatures.

• Cleaner searing with fewer burnt spots on delicate foods.
• Improved smoke circulation for consistent flavor penetration.
• Better baking performance for pizzas, breads, and desserts.
• Versatile enough for searing with one plate or indirect roasting with both.

Who is this for? Grillers who own a 24" kamado-style cooker and want more precise temperature control, safer indirect cooking, and the ability to bake and smoke reliably. These MixRBBQ ceramic half-moon plates suit backyard barbecue enthusiasts, weekend pizza makers, and anyone upgrading a Kamado Joe Big Joe or XL Big Green Egg to a more versatile heat-management system. Before ordering, verify your grill model and measure the grate diameter to confirm the 19.8-inch fit for a smooth installation and satisfying cooking results.
