In a small bowl, combine minced garlic, olive oil, salt, black pepper, rosemary, and thyme.
Rub the garlic mixture over the entire surface of the prime rib.
Place the prime rib in a roasting pan bone-side down.
Roast in the preheated oven for 15 minutes, then reduce the oven temperature to 325°F (163°C) and continue roasting until the desired doneness is reached, approximately 1.5 to 2 hours for medium-rare.
Remove from oven and let the prime rib rest for at least 15 minutes before carving.
Notes
Ensure your prime rib is at room temperature before starting to cook for even cooking.
