Roast in oven until thermometer registers 115Â°-120Â°F for rare or 125Â°-130Â°F for medium. (The internal temperature of the roast will continue to rise after you take the roast out of the oven.). Check the temperature of the roast using a meat thermometer 30 to 45 minutes before you expect the roast to be done.For example, with a 10 pound roast, you would expect 2 1/2 hours of total cooking time (15 minutes at 500Â° and 2 1/4 hours at 325Â°).oast in oven until thermometer registers 115Â°-120Â°F for rare or 125Â°-130Â°F for medium.

Because we roasted the prime rib at 200 F, there won't be much carryover cooking and you don't need to rest it for very long. Once you take the roast out of the oven, the temperature should rise to 130 F, which is perfect medium-rare, and within 20 minutes or so it will drop back down to 120 F. By which time, your oven will have fully reached 500 F.
