This Perfect Garlic Butter Prime Rib Roast is a showstopper for holiday feasts, featuring a foolproof reverse-sear method and a rich garlic-herb butter that creates an incredibly tender, flavorful roast with a perfectly pink interior.

Ingredients

Scale
  • 1/2 cup (1 stick) unsalted butter, softened
  • 6–8 cloves garlic, minced
  • 2 tablespoons fresh rosemary, finely chopped
  • 2 tablespoons fresh thyme leaves
  • 1 teaspoon kosher salt
  • 1/2 teaspoon freshly ground black pepper
  • 1 (4-5 pound) bone-in prime rib roast
  • 2 tablespoons kosher salt
  • 1 tablespoon freshly ground black pepper
  • 1 tablespoon olive oil

Instructions

  1. Remove the prime rib from the refrigerator and let it sit at room temperature for at least 2 hours. Pat it dry with paper towels.
  2. In a small bowl, combine the softened butter, minced garlic, rosemary, thyme, 1 teaspoon of salt, and 1/2 teaspoon of pepper. Mash together with a fork until well combined.
  3. Drizzle the olive oil all over the roast. Season generously with the remaining 2 tablespoons of salt and 1 tablespoon of pepper, rubbing into all nooks and crannies.
  4. Spread the garlic butter evenly over the entire surface of the roast. Tie the roast between the bones with kitchen twine.
  5. Preheat oven to 250°F (120°C). Place the roast on a rack in a roasting pan, fat side up. Insert a probe thermometer into the thickest part of the meat, avoiding bone.
  6. Roast until internal temperature reaches 120°F (49°C) for medium-rare, about 25-30 minutes per pound (2.5-3 hours total).
  7. Remove roast from oven. Increase oven temperature to 500°F (260°C). Tent roast loosely with foil while oven heats.
  8. Remove foil and return roast to the hot oven. Roast for 8-12 minutes until crust is deeply browned and internal temperature reaches 130-135°F (54-57°C) for medium-rare.
  9. Remove roast from oven and transfer to a cutting board. Tent loosely with foil and let rest for at least 20 minutes.
  10. Remove twine and slice between the bones into thick slices. Serve immediately.

Notes

For best results, use a meat thermometer. The reverse sear method ensures even cooking. Let the roast rest at least 20 minutes before carving to retain juices. For a dairy-free option, substitute with vegan butter or ghee.
