Instructions:

Preheat the Oven: Set it to 550°F (290°C).
Season the Meat: Rub the prime rib with garlic powder, salt, and pepper, ensuring it’s well-coated on all sides.
Roast the Meat:
Place the roast fat side up in a shallow roasting pan.
Roast in the oven for:
5 minutes per pound for rare
6 minutes per pound for medium
7 minutes per pound for well-done
Turn off Oven: When the roast is done cooking, turn off the oven and DO NOT open the door for 2 hours. This step allows the roast to continue cooking gently and ensures a perfect finish.
Carve & Serve: After 2 hours, remove the roast, slice, and enjoy!
