You'll need: 

1 prime rib roast with or without bone (any size)

Garlic powder

Salt

Pepper

Directions

Preheat oven to 550F degrees.

Make a rub of salt, pepper and garlic powder and apply to meat. Place meat in a shallow roasting pan fat side up.

Roast at 550 at 5 minutes per pound for RARE, or 6 minutes per pound for MEDIUM and 7 minutes per pound for WELL DONE.

Turn off oven at the end of cooking time and DO NOT OPEN OVEN DOOR FOR TWO HOURS.

At the end of the 2 hours, remove meat from oven to slice; it comes out perfect everytime.

Works the same with Roast beef. Try it you won’t be disappointed.
