Question: how long to cook chicken breast in gas grill?
Answer: Preheat gas grill before cooking to medium-high heat or 350-400° F. Lightly grease grill surface and add chicken. Close lid and cook 8 minutes, or until bottoms are browned with sear marks. Rotate chicken, close lid, reduce heat to medium and cook 7-10 minutes more, or until internal temperature reaches 165° F.
