How Do You Cook Pre Cooked Prime Rib?
To reheat pre-cooked prime rib, preheat your oven to 250°F. Place the prime rib in a shallow pan and cover it with foil. Heat the rib in the oven until the internal temperature reaches 120°F, and let it rest for about 20 minutes before cutting and serving. For a crispy exterior, sear the prime rib in a hot skillet for a few minutes before reheating it in the oven.
