Sear the rib roast (prime rib) for 15 minutes at the higher oven temperature (450 degrees F.), then turn the oven to the lower temperature (325 degrees F.) for the rest of the cooking time. Every 1/2 hour, baste the cut ends of the roast with the fat accumulated in the roasting pan. Do Not Cover the roast.esidual Heat or Carry-Over Cooking: Remember, the rib roast will continue to cook as it sets. The internal temperature will rise to 125 degrees F. to 130 degrees F. (medium rare) in approximately 15 to 20 minutes. If allowed to rest as long as an hour, the internal temperature will rise even higher.
For a rare roast: Allow 15 minutes of cooking time for every pound of roast. For example, if you had a 5 pound roast, you would cook your roast for 75 minutes if you wanted it rare. For a medium rare roast: Cook the roast for 20 minutes for every pound. If you were cooking a 5 pound roast, you would cook it for 100 minutes. For a medium roast: Allow 22 minutes of cooking time for every pound. If you were cooking a 5 pound roast, you would cook the meat for 110 minutes.
