Preheat your gas grill to 400° with the lid closed. When you’re ready to grill, turn grill down to 350°.
Rub the chicken lightly with oil and place skin side down on the grates. Close the lid and cook for about 5 minutes. If the thighs are on the larger side, grill for 7-8 minutes. Do not crowd the chicken on the grate. If you try to turn the chicken and the skin is sticking to the grate, let the chicken cook until it releases. Turn and cook the other side for the same amount of time.
Once preheated, lower the temperature to 350°F. Place
chicken on the grates and close the lid. Grill on one side
for about 7 minutes or until the chicken naturally
releases from the grill.
Move all the pieces to one side of the grill and turn off the burner under the chicken. Brush the skin lightly with BBQ sauce and let cook a further 7-10 minutes with the lid closed. Check with a meat thermometer, you want to cook the chicken until it reaches 165°. Brush chicken with BBQ sauce several times and you can turn the chicken to add BBQ sauce to the other side.
