Prime rib roast

Butter

Several hours before you plan to cook your beef roast, take it out of the refrigerator, and let the roast come to room temperature, anywhere from 2 to 4 hours. This is necessary so that the roast cooks evenly.

Preheat your oven to 450 degrees Fahrenheit.

Pat the room temperature roast dry, and liberally smear softened butter on the ends of the roast. Do NOT salt your rib roast (this will dry it out).

Place the rib roast in a large roasting pan fat side up, on a rack if you have one is preferable. If you’re using a bone-in rib roast, you can omit the cooking rack.

Sear the rib roast at 450 degrees for 15 minutes. Then turn down the oven temperature to 325 degrees Fahrenheit for the remainder of the cooking time. Do NOT cover the roast. Every half-hour or so, baste the roast from the juices that accumulate in the pan.

Cook roast until the internal temperature reaches 120 degrees Fahrenheit (for rare) or your desired level of doneness. Remove roast from the oven, and lightly cover it with aluminum foil. Let rest for 15 to 20 minutes. Remember that the internal temperature will continue to rise as it rests, so take that into consideration before you remove the roast from the oven. After roughly 20 minutes, the internal temperature will be around 125 degrees Fahrenheit if you removed it from the oven at 120 degrees. For us, this is perfectly done (rare), but you may wish to cook your roast longer. You can find cooking times for level of doneness and sizes of prime rib roasts on the What’s Cooking America website here. Enjoy!
