Mix the ground turkey gently with seasonings using just your fingertips until barely combined; overworking creates dense, tough burgers instead of tender ones.

Refrigerate your formed patties for at least 30 minutes before cooking to help them hold their shape and cook evenly without falling apart on the grill.

Press a shallow thumbprint into the center of each patty before cooking; this prevents the burger from puffing up and ensures even, flat cooking throughout.

During the last minute of cooking, brush the burgers with butter infused with extra garlic to amplify the McCormick seasoning and add richness to the leaner turkey meat.

Quickly char the butter lettuce leaves over the grill to add smoky flavor and improve texture, making them sturdier vessels for juicy turkey burgers.
