Garlic Butter Prime Rib Roast for Christmas Recipe
Yield: 6–8 servings · Prep: 20 minutes plus resting · Cook: Approximately 2–3 hours, depending on weight and oven.
Ingredients
- 1 bone-in rib roast, about 5 lb (2.3 kg)
- 4 tablespoons (56 g) softened unsalted butter
- 5 garlic cloves, finely grated
- 1 tablespoon chopped rosemary
- 1 tablespoon chopped fresh thyme
- 2 teaspoons kosher salt
- 1 teaspoon freshly ground black pepper
- 1 tablespoon olive oil
Step-by-Step Instructions
- Refrigerate the roast safely until preparation. Remove packaging, pat the surface dry and place on a rack in a roasting pan. Heat oven to 450°F (230°C).
- Combine butter, garlic, rosemary, thyme, salt and pepper. Rub the roast with olive oil, then spread the seasoned butter over its surface.
- Roast at 450°F (230°C) for 15 minutes to begin browning. Reduce oven to 325°F (163°C) and continue roasting. Insert an oven-safe probe into the thickest part away from bones.
- Cook beef roast to a minimum of 145°F (63°C) with a 3-minute rest, following USDA food-safety guidance. Timing varies significantly with roast size and shape; begin checking well before the estimated finish.
- Remove roast to a board, tent loosely with foil and rest at least 15–20 minutes before carving. Slice against the grain and serve with pan juices.
