*Since you are not opening the oven door, be sure to use a meat thermometer that has an external wire probe that allows you to see the temperature of the meat throughout the cooking process. These numbers I am giving you are just a guide; you should be checking the temperature regularly so the prime rib won’t be overcooked.
