Half-Moon Ceramic Heat Deflector Plates for Kamado Joe Big Joe

Our review of these Half-Moon Ceramic Heat Deflector Plates finds them best for Kamado Big Joe owners who want a reliable, aftermarket way to add indirect heat and turn their grill into a versatile cooker. The biggest reason to buy is the even, consistent heat the cordierite ceramic delivers, which makes smoking, roasting and baking more predictable than direct grate cooking. This 2-pack is sized to work with 19.8 in pizza stones and fits the Big Joe family of cookers, making it a practical upgrade for anyone who wants cleaner drippings and better pizza crusts without replacing factory parts.

Key Features

• Perfect Fit & Performance: Tailored to fit Kamado Joe Big Joe models to create an effective indirect-heat barrier for smoking and roasting.
• Versatile Cooking Upgrade: Supports smoking, roasting and baking so users can move between low-and-slow cooks and high-heat bakes with the same setup.
• Pizza Oven Combo: Works alongside a 19.8 in pizza stone to help deliver a crisper crust and more even bake when making pizzas on the kamado.
• Durable Ceramic Design: Made from high-temp, food grade cordierite ceramic to resist thermal stress during intense grilling sessions.
• Aftermarket Replacement Parts: Provides an affordable alternative to OEM heat deflectors while remaining specific to 15 in and 19.8 in model compatibility.

Who It's For

This set is aimed at kamado enthusiasts who already own a Big Joe or similar 19.8 in cooker and want a simple, durable way to add indirect heat for smoking, roasting or baking.

Those who should look elsewhere include owners of smaller or non-Big Joe kamados that do not match the stated sizes, and cooks who prefer metal deflectors or multi-tiered modular setups; this product is a ceramic aftermarket plate set and is not an OEM part.
