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.
1 Let the pork chops sit out for 20 minutes at room temperature before start to cook. 2  You can preheat your oven to 400Â°F during this time. 3  Dry the pork chop thoroughly with paper towels, then season generously with Kosher salt. 4  It helps to kind of press the salt crystals into the meat so that they really grab on.
