Remove Prime Rib the day you plan to cook it. The best way to cook is at room temperature.
If you desire, salt in the morning about 3-4 hours before cooking. Do you need to salt? No. Will it make it more flavorful? Yes.
Preheat oven to 500°F. (or the hottest temperature your oven will go)
Place carrots and potatoes into a roasting pan, followed by the prime rib fat side up.
Cook Prime Rib for 15 minutes at 500 degrees.
After 15 minutes redice the temperature to 325°F. Cook for 11-12 minutes per pound of roast. (more directions below). You want the internal temperature to be at least 115 Degrees F before removing from the oven.
Once cooked, removed from the oven and allow the roast to sit for 15-20 minutes before cutting.
Cut and serve!
