To cook chicken thighs on the grill, place the thighs on an oiled cooking grate set to medium or high heat. Turn the thighs frequently. Depending on the temperature and the size of the thighs, the cooking time may be between 10 and 20 minutes.
Chicken thighs have a higher fat content than chicken breasts, which helps them stay moist. Before grilling, remove any large fatty areas from the chicken thighs. These could cause flare ups if cooked. Small fat areas don't need to be removed.
There are multiple muscles in a chicken thigh, which means the thigh is loosely connected after the bone is removed. The thigh may be uneven, but this helps it hold onto sauces or rubs.
Cook chicken thighs on high heat or start with high heat to burn some fat off and finish with medium heat to avoid burning the thighs. Smaller thighs should be positioned farther away from the heat to prevent burns. They should be cooked to a temperature of at least 165 degrees Fahrenheit. Signs that a chicken thigh is cooked include a deep golden brown color, juices that run clear and a bit of shrinkage followed by plumping. Thighs don't dry out even if they're a bit overcooked.
