Instructions
1. Prepare the Roast
Remove the prime rib from the fridge 1–2 hours before cooking to bring it to room temperature. Preheat the oven to 450°F (230°C).
2. Season the Roast
Mix olive oil (or butter), minced garlic, salt, pepper, rosemary, and thyme. Rub evenly over the entire roast, including the ends.
3. High-Heat Sear
Place the roast fat-side up (or bone-side down) on a rack in a roasting pan. Roast at 450°F (230°C) for 15 minutes to sear the outside and lock in juices.
4. Lower Heat & Roast
Reduce oven temperature to 325°F (165°C) and continue roasting until the internal temperature reaches:
-
120°F (49°C) for rare
-
130°F (54°C) for medium-rare
-
140°F (60°C) for medium
Cooking time is roughly 1–1.5 hours, depending on the size of the roast.
5. Rest the Meat
Remove from oven and tent loosely with foil. Rest for 20 minutes to allow juices to redistribute.
6. Slice & Serve
Slice against the grain into thick portions. Serve with au jus, horseradish sauce, or roasted vegetables.
