Ingredients:
- 1 bone-in prime rib roast (6–8 pounds)
- 2 tablespoons olive oil
- Salt and pepper, to taste
- Garlic cloves (optional)
Instructions:
- Remove the prime rib from the refrigerator and let it sit at room temperature for 1–2 hours before cooking.
- Preheat the oven to 450°F (230°C).
- Pat the roast dry with paper towels. Rub all over with olive oil, then season generously with salt and pepper. Press garlic cloves into the surface of the roast if using.
- Place the roast, bone-side down, in a roasting pan.
- Roast at 450°F for 20 minutes to develop a flavorful crust.
- Reduce the oven temperature to 325°F (165°C) and continue roasting until the internal temperature reaches:
- 120–125°F for rare
- 130–135°F for medium-rare
- 140°F for medium
- Remove from the oven, tent loosely with foil, and let rest for 20–30 minutes before slicing.
Serving Tips
- Slice against the grain and serve with horseradish sauce or au jus.
- Pair with mashed potatoes, roasted vegetables, or a fresh green salad.
