Kamado Joe Half-Moon Ceramic Heat Deflector Plates for Big Joe — White 2-Pack, Indirect Cooking & Multi-Zone

These two ceramic half-moon heat deflector plates transform a Kamado Joe Big Joe into an efficient indirect smoker and versatile multi-zone cooking system.

Created to work with the Kamado Joe Divide and Conquer Flexible Cooking System, the BJ-HDP 2-pack adds durable ceramic surfaces that block direct flame and retain steady radiant heat. Install them beneath a grill grate to split your Big Joe into a dual-zone cooker for roasting, smoking, or gentle baking without constantly managing flare-ups. The white ceramic is formulated for long heat retention and predictable temperature behavior so you get more consistent results across a wide range of ingredients and techniques.

How do these plates change the way my Big Joe cooks?

Adding the half-moon heat deflectors converts direct-flame grilling into indirect cooking by creating a heat barrier and reflecting heat around food. That means lower, more even temperatures for longer cooks and better control when smoking or roasting delicate items.

• Creates an indirect heat zone for low-and-slow cooks
• Reduces flare-ups by shielding food from direct coals
• Encourages even radiant heat distribution around the cooking surface

Will these ceramic plates fit my Kamado Joe model and cooking grid?

The BJ-HDP plates are sized for the Big Joe family — Big Joe I, II, and III — and integrate with the Divide and Conquer system to sit under the grill grate or alongside other inserts. They’re designed to pair with standard Big Joe grates without modification.

• Compatible with Big Joe I, II & III cookers
• Works with the Divide and Conquer flexible grid layout
• Installs quickly without tools; simply place inside the grill

What cooking styles benefit most from these heat deflectors?

These ceramic plates excel for smoking, roasting, braising, and baking where steady, indirect heat is preferred over direct searing. Use them when cooking larger roasts, whole poultry, baked casseroles, or when you need to keep food warm away from open flame.

• Ideal for low-and-slow smoking and roast-style cooking
• Great for baking pizzas, breads, or casseroles with controlled heat
• Perfect for two-zone setups: sear on one side, roast or rest on the other

How do I care for and store the ceramic deflectors?

Ceramic is low-maintenance but benefits from gentle handling. Clean off ash and food residues after the cooker cools, avoid rapid thermal shocks, and store indoors or in a dry place to prevent long-term exposure to moisture.

• Let plates cool completely before cleaning
• Brush off ash; wash with mild soap and water if needed
• Do not immerse hot ceramic in cold water to prevent cracking
