Ingredients Method

Ingredients
  

  • 5 pounds prime rib roast
  • 1 tablespoon kosher salt
  • 1 tablespoon freshly ground black pepper
  • 2 cloves garlic minced (optional)

Method
 

  1. Pat the roast dry and season with kosher salt, pepper, and minced garlic. Place uncovered in the refrigerator for 24 hours to dry-brine.
  2. Remove the roast from the refrigerator 2 hours before cooking to let it come to room temperature.
  3. Preheat the oven to 250°F (120°C). Place the roast on a rack in a roasting pan and cook until the internal temperature reaches 120°F (about 2½–3 hours).
  4. Increase oven temperature to 500°F (260°C) and roast for an additional 10–15 minutes to develop a golden crust.
  5. Remove the roast, tent with foil, and let rest for 30 minutes before slicing against the grain.
