The recommended cooking time for pork chops on the grill depends on the thickness of the chops and the temperature of the grill. Pork chops that are 3/4-inch thick should generally be cooked for approximately eight to 10 minutes. They should be flipped halfway through cooking.
Thicker chops should be grilled for about 12 to 16 minutes, again flipping them halfway through to ensure that they are done. To find out if a pork chop is finished cooking, use a meat thermometer. Pork chops should reach an internal temperature of 140 degrees Fahrenheit, and should be allowed to sit for 5 minutes before served.
