Ingredients

Scale
  • 45 pounds prime rib roast, bone-in or boneless
  • 2 tablespoons olive oil
  • 2 tablespoons fresh rosemary, finely chopped
  • 2 tablespoons fresh thyme leaves, stripped from stems
  • 4 garlic cloves, minced
  • 1 tablespoon coarse salt
  • 1 teaspoon freshly ground black pepper
  • 1/2 cup sour cream (full-fat recommended)
  • 2 tablespoons prepared horseradish
  • 1 tablespoon mayonnaise
  • 1 teaspoon fresh lemon juice
  • Salt and pepper to taste

Instructions

  1. Remove the prime rib from the fridge about 1 hour before cooking to bring it to room temperature.
  2. Preheat oven to 450°F (232°C).
  3. In a bowl, mix olive oil, rosemary, thyme, garlic, coarse salt, and black pepper to form an herb paste.
  4. Pat the roast dry with paper towels to remove moisture.
  5. Rub the herb mixture all over the roast, pressing gently to adhere.
  6. Place the roast on a rack in a roasting pan and roast at 450°F for 15 minutes to form a crust.
  7. Reduce oven temperature to 325°F (163°C) and continue roasting until internal temperature reaches 125°F (52°C) for medium-rare, about 1 hour 15 minutes to 1 hour 30 minutes. Start checking after 1 hour.
  8. Remove roast from oven and tent loosely with foil. Let rest for 20 minutes to redistribute juices.
  9. While the roast rests, mix sour cream, prepared horseradish, mayonnaise, lemon juice, salt, and pepper in a small bowl. Chill until serving.
  10. Slice the roast across the grain into 1/2-inch thick slices and serve with horseradish cream.

Notes

Bring the roast to room temperature before cooking for even roasting. Use a meat thermometer for perfect doneness. Resting the meat is crucial to retain juices. Horseradish cream can be made ahead and chilled. If fresh herbs are unavailable, use one-third the amount of dried herbs. For a milder horseradish cream, reduce horseradish or substitute half sour cream with Greek yogurt.
