Ingredients

• 2 teaspoons salt

• 2 tablespoons dry red wine
• 1 (10 pound) prime rib loin roast
• 2 cups concentrated beef base (paste)
• 1 tablespoon concentrated beef base (paste)
• 1 stalk celery, quartered
• 0.5 teaspoon garlic powder
• 2.5 cups water

• 0.5 medium white onion, coarsely chopped
• 0.5 medium carrot, peeled and coarsely chopped

Recipe Instructions

Step 1

Roast in the preheated oven until meat has formed a brown crust, about 3 hours. An instant-read thermometer inserted into the thickest part of the roast should read 130 degrees F (54 degrees C) for medium-rare. Remove from the oven and let stand while you make the sauce; the temperature will rise 5 to 10 degrees F as it rests.

Step 2

To make the roast: Preheat the oven to 350 degrees F (175 degrees C). Trim any thick pieces of dense, hard fat from roast, but leave smaller areas of fat in place.

Step 3

Mix beef base and garlic together in a bowl. Mix thyme, oregano, peppercorns, and salt together in a separate bowl. Rub beef base mixture generously all over roast, then sprinkle with herb mixture. Place roast into a heavy-based roasting pan.

Step 4

To make the au jus: Whisk water and beef base together in a saucepan over medium-low heat until base dissolves. Whisk in red wine, thyme, oregano, and garlic powder, then add onion, carrot, and celery. Bring to a boil, then reduce the heat and simmer, stirring frequently, until sauce reduces by about half, 20 to 30 minutes. Strain au jus and discard vegetables. Serve with roast.
