Ingredients

Scale
  • 56 pounds prime rib roast, bone-in or boneless
  • 45 cloves garlic, minced
  • 23 sprigs fresh rosemary, chopped
  • 23 sprigs fresh thyme, chopped
  • 2 tablespoons olive oil
  • 1 tablespoon kosher salt
  • 1 tablespoon freshly ground black pepper
  • 23 tablespoons prepared horseradish
  • 1 cup sour cream
  • 1 teaspoon lemon juice
  • 1 teaspoon white vinegar

Instructions

  1. Rub the prime rib with olive oil, garlic, rosemary, thyme, salt, and pepper, covering all sides evenly.
  2. Let the seasoned roast sit at room temperature for 1–2 hours to ensure even cooking.
  3. Preheat the oven to 450°F (232°C) for the initial sear.
  4. Place the prime rib in a roasting pan and cook at 450°F for 20 minutes to create a golden-brown crust.
  5. Reduce the oven temperature to 325°F (163°C) and cook until the internal temperature reaches 120°F (49°C) for medium-rare, about 15 minutes per pound.
  6. In a mixing bowl, whisk together sour cream, horseradish, lemon juice, and white vinegar. Chill until ready to serve.
  7. Remove the prime rib from the oven and tent with foil. Let it rest for 20 minutes before carving.
  8. Carve into thick slices and serve with horseradish cream on the side.

Notes

[‘Let the roast come to room temperature before cooking for even doneness.’, ‘Don’t skip the initial sear—it locks in flavor and creates the signature crust.’, ‘Use fresh herbs whenever possible for elevated flavor.’, ‘Monitor the meat thermometer closely to avoid overcooking.’, ‘Make the horseradish cream a day ahead to let the flavors meld.’]
