I do this every Christmas and it is great. My guests brag about my prime rib.
Heat oven to 500 degrees. Put prime rib in oven covered for 1 hour. After one hour, turn oven off and leave it in for 90 minutes. Comes out perfect. If you want it a little more done, leave in longer. No peeking while it is cooking.
