I bought a Prime Rib for Christmas Dinner.  What's the tastiest way to roast it?

Preheat your oven to 425F. Rub the roast with olive oil, salt and pepper. Place it on a rack in a roasting pan and sprinkle with brown sugar and any favorite spices. Place the roasting pan in the oven and cook for about 17 minutes per pound for rare doneness. After 30 minutes of cooking time, flip the roast and continue cooking until an internal thermometer reads 135F for medium-rare. Allow the roast to rest for 20 minutes before serving.
