You can reheat the leftover pork chops and sauerkraut in a skillet on the stove, or in a microwave-safe bowl in the microwave. You can also wrap the leftovers in aluminum foil and put them in a baking dish in a preheated oven at 325 degrees Fahrenheit, then bake pork chops just until hot. Wrapping them in aluminum foil makes for an easy baking dish clean up.
