1 While the roast is resting prepare the au jus; place the roasting pan on top of the stove over high heat. 2  Add in the wine; cook for 8-10 minutes, stirring and scraping any brown bits. 3  Add in the beef stock; cook and reduce the juice by half (this might take about 20 minutes). 4  Add salt and pepper to taste.

4 Place the roast fat side up and rib bones down in a roasting pan. Insert a meat thermometer into the thickest part of the roast, making sure that the thermometer isn't touching a bone. 5 After browning the roast at a 500Â°F temperature in the oven for 15 minutes, reduce the oven temperature to 325Â°F.To figure out the total cooking time, allow about 13-15 minutes per pound for rare and 15-17 minutes per pound for medium rare. prime rib roast is too expensive to wing it. Error on the rare side, you can always put the roast back in the oven to cook it more if it is too rare for your taste. Roast in oven until thermometer registers 115Â°-120Â°F for rare or 125Â°-130Â°F for medium.
