Ingredients

Scale

For the Prime Rib:

  • 1 (5 to 6 lb) prime rib roast (bone-in or boneless)

  • 2 tbsp salt

  • 1 tbsp black pepper

Garlic-Herb Crust:

  • 8 garlic cloves, minced

  • 1/4 cup fresh rosemary, chopped

  • 1/4 cup fresh thyme, chopped

  • 1/2 cup olive oil (or melted beef tallow)

  • 2 tsp onion powder

  • Optional: pinch of red pepper flakes

Instructions

  1. Let the prime rib sit at room temperature for 1 to 2 hours.

  2. Preheat oven to 250°F.

  3. In a small bowl, mix garlic, rosemary, thyme, olive oil, onion powder, and red pepper flakes until it forms a paste.

  4. Season the roast all over with salt and pepper. Then rub the garlic-herb paste over the entire roast.

  5. Place roast fat-side up on a rack in a roasting pan.

  6. Roast until internal temperature hits 120°F (rare) to 135°F (medium), about 2.5 to 3.5 hours.

  7. Remove from oven and rest for 30 minutes.

  8. Increase oven to 500°F. Return roast to oven for 10-15 minutes to brown the crust.

  9. Let rest again for 10 minutes before slicing and serving.

Notes

  • Use a meat thermometer for best results.

  • Don’t skip the resting time—this keeps the meat juicy.

  • Leftovers are great in omelets or lettuce wraps.

  • Fresh herbs are best, but dried can be used in a pinch (use 1/3 of the amount).
