Prime Rib Roast with "Au Jus"
15 min
18-22 min/lb




  • 3 1/2 teaspoons Mediterranean sea salt
  • 1 1/2 teaspoon freshly coarse ground black pepper
  • 2 heads of roasted garlic
  • 3 tablespoons of butter
  • 1 tablespoon finely chopped fresh thyme leaves
  • 1 tablespoon finely chopped fresh rosemary
  • 1 prime rib roast of beef (calculate 1 bone for 2-3 people)
  • 2 1/2 cups red wine
  • 2 1/2 cup beef stock


Preheat the oven to 450 degrees F. Separate the heads of roasted garlic into cloves and squeeze the roasted garlic out of the peels. Place the garlic in a small bowl and mash with the back of a fork until mostly smooth. Add softened butter, 1 teaspoon salt, 1/2 teaspoon pepper, the rosemary and thyme, and stir to blend. Pat this mixture evenly over the top and sides of the roast. Season the roast all over with the remaining 2 1/2 teaspoons salt and 1 teaspoon of pepper. Place the roast in a roasting pan and add 1 1/2 cups red wine and 1/2 cup beef stock to the bottom of the pan. Roast for 20 minutes. Reduce the heat to 350 degrees F and continue to roast to the desired degree of doneness, about 18 minutes per pound for rare and 22 minutes per pound for medium. Let stand at least 5 minutes before carving. (We strongly suggest the use of a good meat thermometer to verify temperature. Be sure the tip of the thermometer is in the thickest center of the roast. )

 To make au jus, place the roasting pan on the stove burners over medium-high heat. Add 1 cup red wine and scrape the browned bits on the bottom of the pan with a wooden spoon. Add 2 cups beef stock and season with salt and pepper. Continue to cook until the wine is reduced by half, about 5 minutes. Strain the sauce through a sieve to remove the solids before serving. De-grease, if necessary.
