Use direct heat for searing and quickly cooking foods like steaks, burgers, and vegetables. Use indirect heat for slower cooking of larger cuts of meat like roasts, ribs, or whole chickens, or for baking.
Direct heat grilling involves placing food directly over the heat source (flames or hot coals). This method is ideal for foods that cook quickly, typically in under 20 minutes. The high heat sears the surface, creating a flavorful crust and locking in juices. Examples include steaks, burgers, chicken breasts, vegetables like bell peppers and zucchini, and seafood like shrimp and fish fillets.
Indirect heat grilling involves placing food next to, but not directly over, the heat source. The grill lid is closed, and the hot air circulates around the food, cooking it more slowly and evenly, similar to an oven. This method is best for larger cuts of meat that require longer cooking times, such as roasts, ribs, whole chickens, and pork shoulders. It's also suitable for delicate foods that might burn over direct heat, or for baking items like pizza or desserts on the grill. You can achieve indirect heat by using only burners on one side of a gas grill or by arranging charcoal on either side of the grill with a drip pan in the middle.
For thicker cuts of meat, consider using a combination of direct and indirect heat. Sear the meat over direct heat to develop a crust, then move it to indirect heat to finish cooking through without burning the outside. This is often referred to as the 'reverse sear' method.
