Now the USDA says it's safe to cook pork to 145Â°F, which is in effect, medium as opposed to well-done. Pork cooked medium might look a little bit pink in the middle, but that's perfectly all right. In fact, it's great. My own personal preference for cooking pork is 135Â° to 140Â°F.
Bake pork chops at 300 degrees F for 20 to 30 minutes while checking them frequently. Cover them with aluminum foil to keep moisture in. When buying pork chops, look for those that are pink and have no odor. Avoid those that are gray, white or have a soggy texture or liquid in the tray. These pork chops were probably not processed correctly.
