Cooking Instructions

  1. 1

    Prepare the Prime Rib

    Preheat your oven to 450°F (232°C). Season the prime rib roast generously with salt, black pepper, garlic powder, and onion powder. Place it on a roasting rack in a roasting pan.

  2. 2

    Roast the Beef

    Roast the beef in the preheated oven for 20 minutes. Then, reduce the temperature to 325°F (163°C) and continue roasting until a meat thermometer reads 130°F (54°C) for medium-rare, about 1.5 to 2 hours. Remove from the oven and let rest for 20 minutes.

  3. 3

    Prepare the Au Jus

    While the meat is resting, pour the beef broth into the roasting pan and heat over medium heat, scraping up any browned bits from the bottom. Let it simmer for about 10 minutes.

  4. 4

    Toast the Bread

    Spread butter on one side of each slice of sourdough bread. Toast them in a skillet or under a broiler until golden brown.

  5. 5

    Assemble the Sandwich

    Slice the prime rib into 6 oz. portions. Place the sliced beef on the toasted bread and drizzle with au jus. Garnish with fresh herbs, if desired.
