  • 1 tbsp Dried rosemary
  • 2 tbsp Olive oil
  • 2 cups Beef stock (Low-sodium preferred)

  • 4 whole Fresh thyme sprigs (For roasting)
  • 2 whole Fresh rosemary sprigs (For roasting)
  • 6 whole Garlic cloves (Smashed)
  • 2 tbsp Unsalted butter (For au jus)

Tools You'll Need

  • Large roasting pan
  • Meat thermometer
  • Carving knife and fork
  • Cutting board
  • Aluminum foil
  • Fine-mesh strainer
  • Gravy boat
  • Paper towels

Chef's Tip

Use a reliable meat thermometer inserted into the thickest part of the roast, avoiding bone, for the most accurate cooking. Remember that the internal temperature will continue to rise about 5-10°F while resting, so remove the roast from the oven when it's 5°F below your target temperature.

Instructions

  1. Remove rib roast from refrigerator and let stand at room temperature for 1 hour before roasting.
  2. Preheat oven to 450°F with rack in lower third position.
  3. In a small bowl, mix together kosher salt, black pepper, garlic powder, dried thyme, and dried rosemary.
  4. Pat roast dry with paper towels. Rub all surfaces with olive oil, then apply herb mixture generously, pressing to adhere.
  5. Place roast bone-side down in a large roasting pan. Scatter fresh thyme sprigs, rosemary sprigs, and smashed garlic cloves around the roast.
  6. Roast at 450°F for 20 minutes to develop a crust, then reduce temperature to 325°F.
  7. Continue roasting until internal temperature reaches 120-125°F for medium-rare (about 15 minutes per pound after the initial high-heat roasting).
  8. Transfer roast to a cutting board, tent loosely with foil, and rest for 20-30 minutes before carving.
  9. While roast rests, make the au jus: Pour off all but 2 tablespoons of fat from the roasting pan. Place pan over medium heat.
  10. Add red wine and scrape up browned bits from bottom of pan. Simmer until reduced by half.
  11. Add beef stock and Worcestershire sauce, bring to a simmer and reduce by one-third, about10 minutes.
  12. Strain sauce into a gravy boat, whisk in butter, and keep warm until serving.
  13. To carve, remove bones by cutting along the rib line, then slice meat across the grain into 1/2-inch slices.

Plating

Arrange slices of prime rib slightly overlapping on a pre-warmed platter with a slight pool of au jus beneath the meat. Serve additional warm au jus in a gravy boat alongside. Garnish the platter with fresh herb sprigs if desired. For individual servings, place 2-3 slices on each warmed plate with a small pool of au jus.

Storage & Reheating

Leftover prime rib can be stored in an airtight container in the refrigerator for up to a4 days. Store the au jus separately. To reheat, place slices in a covered baking dish with a small amount of au jus and warm in a 300°F oven just until heated through, about 15-20 minutes. Alternatively, sliced prime rib makes excellent cold sandwiches with horseradish cream.

About This Recipe

This prime rib preparation is inspired by the signature roasts served at Hilltop Steakhouse. The slow-roasting method with an initial high-heat sear creates the perfect balance of a flavorful crust and tender, juicy interior. The au jus, made from the roast's natural drippings, enhances the rich beef flavor for an authentic steakhouse experience.
