Cooking times vary depending on the thickness of the cut of meat; however, pork must be heated to a minimum internal temperature of 145 degrees in order to be considered safe for consumption. Depending on the size of the pork chop, that could take anywhere from 8 to 35 minutes.
To ensure a safe temperature, an internal cooking thermometer should be used to verify the temperature of the meat. As a rough estimate, however, 3/4 inch thick pork chops should be broiled for 8-12 minutes, while 1 1/2 inch thick pork chops should be broiled for 22-35 minutes. Always remember that cook time does not scale linearly with thickness.
