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.
Once all the pork chops are seared, fit them all into the pan at the same time. Slide the frying pan into the oven. Cook the pork chops for 15 to 20 minutes, until a meat thermometer inserted in the pork reads 140Â°F (60Â°C). Remove the pork chops from the oven, cover with foil, and let rest for 5 minutes before serving.
