2-Ingredient Prime Rib

Ingredients :

• Prime Rib Roast (standing rib roast), at room temperature (very important)
• 2 tablespoons butter, room temperature

Instructions :

1. 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.
2. Do NOT salt the outside of your prime rib roast, as salt draws out moisture from the meat while cooking.
3. Place the roast, ribs down or fat side up, in a heavy stainless-steel Roasting Pan or other metal roasting pan.
4. Sear the rib roast (prime rib) 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.
5. 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 don’t want anything to go wrong. This is even more important if you are adjusting for High Altitude Baking.
6. When checking the temperature of your prime rib roast, insert meat thermometer so tip is in thickest part of beef, not resting in fat or touching bone. Cook until rib roast reaches an internal temperature of 120 degrees F. (or your desiredtemperature). Remove from oven, cover loosely with aluminum foil, and let sit approximately 15 to 20 minutes.
