Directions:Preheat oven to 450 degrees F. Pat the room-temperature standing rib roast (prime rib roast) dry with paper towels or napkins. Smear the cut ends only of the roast with the butter.
Room Temperature: To cook evenly, the roast must not be cold - let it stand at room temperature, loosely covered, for about 2 to 4 hours. This time can vary depending on how big or small your roast is. I can not give you an exact time on this. If you do not let the roast come to room temperature, if will take longer to cook your roast, your roast won't cook evenly, and you will end up with well-done slices on the end and raw meat in the center. Use your best judgment on room temperature times!
Roasting Pan: Place the roast, ribs down or fat side up, in a heavy stainless-steel Roasting Pan or other metal roasting pan. Select a roasting pan that has sides at least 3-inches deep. (I do not recommend using nonstick pans, as these pans yield fewer of the cooked-on bits that make the tasty au jus juice or gravy.) The rib bones are a natural rack; you will not need a metal one.
Cooking Temperatures: Sear the rib roast 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.
You will want to estimate about 12 minutes per pound of meat for the cooking time. See charts to make it easy to determine Prime Rib Roast Cooking Times. About 45 minutes before the estimated end of the roasting (bake) time, begin checking the internal temperature (use a good instant-read digital meat thermometer). Play it safe and start checking early, as you do not want anything to go wrong.
Approximate Prime Rib Cooking Time Per Pound until Internal Temperature reaches 120 degrees F:
1 rib (2 to 2.5 pounds) – 22 to 24 minutes
2 ribs (4 to 5 pounds) – 60 to 70 minutes
3 ribs (7 to 8.5 pounds) – 1-1/2 to 1-3/4 hours
4 ribs (9 to 10.5 pounds) – 1-3/4 to 2-1/4 hours
5 ribs (11 to 15 pounds) – 2-1/4 to 3 hours
6 ribs (15 to 16 pounds) – 3 to 3-1/4 hours
7 ribs (16 to `8.5 pounds) – 3-1/4 to 4 hours
