Ingredients

Scale
  • 45 pounds prime rib roast, bone-in or boneless
  • 1/2 cup (115g) unsalted butter, softened
  • 6 cloves fresh garlic, minced
  • 2 tablespoons fresh rosemary, finely chopped
  • 1 tablespoon fresh thyme, finely chopped
  • 2 teaspoons kosher salt
  • 1 teaspoon freshly ground black pepper
  • Horseradish Cream:
  • 1/2 cup (120ml) sour cream
  • 2 tablespoons prepared horseradish
  • 1 teaspoon lemon juice
  • Salt and pepper, to taste

Instructions

  1. Remove the roast from the fridge about 1 hour before cooking to bring it to room temperature.
  2. In a bowl, combine softened butter, minced garlic, chopped rosemary, thyme, salt, and pepper. Mix until fragrant and creamy.
  3. Pat the roast dry with paper towels. Generously spread the garlic butter all over the roast, pressing it into the surface.
  4. Preheat oven to 450°F (230°C). Place the roast fat side up on a rack in a roasting pan.
  5. Roast for 15 minutes to develop a golden brown crust.
  6. Reduce oven temperature to 325°F (160°C) and continue cooking. Use a meat thermometer inserted into the thickest part of the roast. For medium-rare, pull the roast at 125°F (52°C).
  7. Tent the roast loosely with foil and let it rest for 20-30 minutes to redistribute juices.
  8. While the roast rests, stir together sour cream, horseradish, lemon juice, salt, and pepper in a bowl. Adjust horseradish to taste.
  9. Slice the prime rib against the grain into thick slices and serve immediately with horseradish cream.

Notes

Bring the roast to room temperature before cooking for even doneness. Pat dry before applying garlic butter to ensure a crispy crust. Use a meat thermometer to avoid overcooking. Rest the roast for 20-30 minutes to keep it juicy. Tent with foil if crust browns too quickly. Horseradish cream can be made dairy-free by substituting sour cream with coconut yogurt.
