Ingredients:
- 8 lb bone-in prime rib roast
- 2 tbsp kosher salt
- 1 tbsp coarsely ground black pepper
- 1 cup unsalted butter, softened
- 6 cloves garlic, minced
- 2 tbsp fresh rosemary, finely chopped
- 2 tbsp fresh thyme, finely chopped
- 1 tbsp Worcestershire sauce
- 2 cups beef bone broth
- 1/2 cup dry red wine
Instructions:
- Pat the roast dry with paper towels. Rub the entire surface generously with kosher salt. Place on a rack over a baking sheet and refrigerate uncovered for 24 hours to dry the exterior and season the meat.
- Remove the roast from the refrigerator 2 hours before cooking to reach room temperature. Tie the roast between the bones with butcher's twine to maintain a uniform shape.
- In a small mixing bowl, combine softened butter, minced garlic, rosemary, thyme, black pepper, and Worcestershire sauce. Spread the compound butter thick over the top and sides of the roast.
- Preheat oven to 250°F (120°C). Place the roast bone-side down on a roasting rack. Insert a digital thermometer and roast until the internal temperature reaches 120°F (49°C) for medium-rare.
- Remove the roast from the oven and tent loosely with foil. Let it rest for 30 to 45 minutes. The temperature will rise to 130°F-135°F via carryover cooking.
- Increase oven temperature to 500°F (260°C). Return the rested roast to the oven for 6–10 minutes until the exterior is deeply browned and sizzling. Serve with au jus made from pan drippings, wine, and beef broth.
