A flavorful and tender prime rib roast rubbed with fresh garlic and rosemary, roasted low and slow to create a golden crust and juicy interior. Perfect for special occasions and easy enough for any home cook.

Ingredients

Scale
  • 1 (5-pound) bone-in prime rib roast, well-trimmed (USDA Choice or Prime grade recommended)
  • 68 cloves fresh garlic, minced or finely grated
  • 3 tablespoons fresh rosemary, finely chopped
  • 2 tablespoons olive oil (extra virgin preferred)
  • 2 tablespoons coarse kosher salt (Diamond Crystal brand recommended)
  • 1 tablespoon freshly ground black pepper
  • 1 teaspoon smoked paprika (optional)

Instructions

  1. Preheat your oven to 450°F (232°C).
  2. Pat the prime rib dry with paper towels and trim any excess silver skin. Let the roast sit at room temperature for about 30 minutes.
  3. In a mixing bowl, combine minced garlic, chopped rosemary, olive oil, kosher salt, black pepper, and smoked paprika if using. Stir until it forms a paste.
  4. Rub the garlic-rosemary mixture all over the roast, pressing it in to stick well.
  5. Place the roast bone-side down on a rack in a roasting pan and put it in the preheated oven for 15 minutes to sear and lock in juices.
  6. Reduce oven temperature to 325°F (163°C) and roast for approximately 12-15 minutes per pound for medium rare (about 1 hour 15 minutes for 5 pounds). Use a meat thermometer to check doneness: 120-125°F (49-52°C) for rare, 130-135°F (54-57°C) for medium rare.
  7. Remove the roast from the oven and tent loosely with foil. Let it rest for 20-30 minutes to allow juices to redistribute.
  8. Slice the roast against the grain into thick slices and serve.

Notes

Bring the meat to room temperature before roasting to ensure even cooking. Do not skip the initial high-heat sear at 450°F to create a crispy crust. Use a meat thermometer for accurate doneness. Rest the roast for 20-30 minutes before slicing to keep it juicy. If you don’t have a roasting rack, improvise with crumpled foil. Avoid opening the oven door frequently to maintain temperature.
