Roast Prime Rib Au Jus

NR_Prime Rib Roast crop [1]Serves 4-6

Free of: gluten and all top allergens



  1. Heat oven to 500° F. Meanwhile bring the roast to room temperature.
  2. In a small bowl, combine garlic, thyme, oil, pepper and salt. Rub mixture over the roast, coating well.
  3. Place beef, fat side up, into roasting pan. Cook for 45 minutes at 500° F.
  4. Turn oven off, do not open oven door for two hours* (This maintains a steady, decreasing temperature, so the roast will be cooked.)
  5. Meanwhile, combine remaining ingredients into a medium saucepan.
  6. Boil until reduced to 2 cups. Remove bay leaves and serve this “jus” over sliced roast beef.

*Note: This is Chef Simon’s preferred method for cooking a medium-rare prime rib roast. For a 2-rib roast, cook at  500° F for 30 minutes; for a 4-5 rib roast, cook at same temperature for one hour. For any size roast, follow with the 2 hours in closed oven with temperature off. (No peeking!)
