Question: how long does it take to cook a pork roast at 250 degrees?
Answer: To cook pork roast uncovered in the oven at 250 F, first preheat your oven and then pat your roast dry with paper towels and season with salt and pepper. Use a roasting pan with a rack and cook in your oven until your roast reaches an internal temperature of 145 F, about 7 to 8 hours.
