Main Ingredients

  • 1 whole prime rib roast (bone in or boneless) Choose according to preference.
  • 2-3 tablespoons kosher salt Use less if using fine salt.
  • 1 tablespoon black pepper
  • 8-10 cloves garlic, minced or grated
  • 2 tablespoons fresh rosemary, chopped Or 2 teaspoons dried.
  • 2 tablespoons fresh thyme, chopped Or 2 teaspoons dried.
  • 3-4 tablespoons olive oil or softened butter
  • 1 teaspoon onion powder Optional.

Instructions
 

Preparation

  • Salt the roast the day before if possible and refrigerate uncovered. If not, salt 1-2 hours before cooking.
  • Take the roast out of the fridge 1-2 hours before cooking to bring it close to room temperature.
  • Mix garlic, pepper, rosemary, thyme, and olive oil or butter into a paste. Rub extensively over the roast.

Cooking

  • Preheat the oven to 225°F. Place the roast on a rack fat side up.
  • Cook until the internal temperature hits desired doneness (Rare: 120°F, Medium rare: 125°F, Medium: 130°F). This typically takes around 3-4 hours.
  • Tent the roast with foil and let it rest for 25-40 minutes.
  • Increase oven temperature to 500°F and return the roast to the oven for 6-10 minutes until browned.
  • Rest for another 10-15 minutes before carving thick or thin slices as desired.

Serving Tips

  • Serve with sides like mashed or roasted potatoes, a salad, warm bread, and extra sauce.
  • Store any leftovers sliced, with a little au jus, for easy reheating.

Notes

Salting ahead improves flavor and texture. A meat thermometer is essential for perfect doneness.
