Before adding the chicken to the grill, make sure to lightly oil and coat the surface of the meat with a high smoke point oil. Olive oil or grapeseed are my top choices. This process helps to prevent the chicken and spices from sticking to the grill plate.
If your grill has a cover, always cook your chicken with the cover down. It will make your grill more oven-like, and your food will cook more evenly. Also, because the cover cuts off some of the oxygen, you’ll have fewer flare-ups.
