Preheat oven to 450°F (230°C). In a small bowl, combine olive oil, garlic, salt, pepper, rosemary, and thyme. Rub mixture all over the prime rib roast. Place roast fat-side up on a roasting rack in a roasting pan.
Roast at 450°F (230°C) for 15 minutes, then reduce temperature to 325°F (165°C) and continue cooking for 1½–2 hours (about 15 minutes per pound) for medium-rare, or until desired doneness. Let the roast rest 15–20 minutes before slicing. Optional: use pan drippings with beef broth to make a simple au jus. Rich, flavorful, and melt-in-your-mouth tender — a prime rib that will impress everyone at the table!
