The Big Blue Egg charcoal grill heat deflector is a heavy-duty insert designed to create indirect, even heat for low-and-slow cooking. Placed between the charcoal and the cooking grate, it blocks direct flame while distributing heat throughout the grill, preventing hot spots and flare-ups. Ideal for smoking, roasting, and baking, the heat deflector helps maintain consistent temperatures, improves fuel efficiency, and protects food from scorching. Typically made from ceramic or thick steel, it’s an essential accessory for turning a charcoal grill into a versatile outdoor oven.
