A beef roast cooked to medium-rare should have an internal temperature of 145Â°F - 150ÂºF after the resting period, and a roast cooked to medium should have an internal temperature of 150Â°F to 160ÂºF. (See the note below). See Beef Doneness for more information on proper cooking temperatures.enerally, the roasting time may range from 15 to 30 minutes per pound.

Serves 4 to 8 people depending on the size of the roast. Note: For medium-rare prime rib, we want to take the roast out of the oven at 120Â°F, and it will continue cooking until it reaches 130Â°F. If you prefer a medium prime rib, take it out at 130Â°F with a target temperature of around 140Â°. Roast for 20 minutes, then lower the heat to 325Â°F and roast until the meat's internal temperature reaches 120Â°F, which will be another hour to three and a half hours, depending on the size of your roast.
