Ruth’s Chris–Style Roasted Garlic & Herb Prime Rib

Instructions:

  1. Remove the prime rib from the refrigerator 1 to 2 hours before cooking to allow it to come to room temperature.
  2. Preheat the oven to 450°F (232°C). Place a roasting rack inside a roasting pan.
  3. In a small bowl, combine the butter, olive oil, garlic, rosemary, thyme, parsley, salt, pepper, onion powder, and smoked paprika until well mixed.
  4. Pat the roast dry with paper towels. Rub the garlic-herb butter generously over all sides of the meat.
  5. Place the roast bone-side down on the rack in the prepared roasting pan.
  6. Roast at 450°F for 20 minutes to develop a rich, flavorful crust.
  7. Reduce the oven temperature to 325°F (163°C) and continue roasting until desired doneness is reached:
    • Rare: 120–125°F internal temperature, about 1 hour 15 minutes more
    • Medium-rare: 130–135°F internal temperature, about 1 hour 25 minutes more
  8. Remove the roast from the oven and tent loosely with foil. Let it rest for at least 20 minutes before slicing.
  9. Slice thickly and serve warm.

Variations

  • Add crushed garlic cloves and fresh herb sprigs to the roasting pan for extra aroma.
  • Substitute fresh oregano or sage for part of the rosemary and thyme for a different herbal profile.
  • Finish with a horseradish cream sauce or red wine jus for a classic steakhouse pairing.

Tips

  • Always use a meat thermometer to ensure accurate doneness.
  • Do not skip the resting period; it allows the juices to redistribute for maximum tenderness.
  • Slice against the grain for the most tender texture.
  • For an authentic steakhouse presentation, serve with warm plates and a drizzle of melted butter or au jus.
