How do You Cook Prime Rib?

Prime rib is easy to make. Place in a shallow baking pan with the fat side up. If you like garlic, you can cut slits in your prime rib and stuff garlic cloves in each slit. Salt and pepper and drizzle a little oil on top. Cook at 450 for 20 minutes and then reduce heat to 350. Cook 20 minutes per pound for a medium rare roast.
