Instructions

  1. Step 1: Preheat your oven to 450°F (232°C). In a small bowl, combine 1/2 cup softened unsalted butter, 6 minced garlic cloves, 2 tbsp chopped fresh rosemary, 1 tbsp chopped fresh thyme, 2 tsp kosher salt, and 1 tsp freshly ground black pepper, mixing until well incorporated.
  2. Step 2: Pat dry 5 pounds of USDA prime rib roast with paper towels. Rub the roast evenly all over with 2 tbsp olive oil, then spread the garlic and herb butter mixture generously on all sides of the meat, pressing it into the surface.
  3. Step 3: Place the prime rib on a rack in a roasting pan, fat side up, and roast at 450°F for 20 minutes to develop a crust. Then reduce the oven temperature to 325°F (163°C) and continue roasting for approximately 1 hour and 15 minutes, or until an internal thermometer reads 130°F (54°C) for medium-rare.
  4. Step 4: Remove the roast from the oven and tent loosely with aluminum foil. Let it rest for 20 minutes so the juices redistribute before carving into thick slices.
