Method

For the Sandwich

  1. 1

    Prepare the Prime Rib

    Preheat the oven to 325°F (163°C). Season the prime rib roast with salt, black pepper, garlic powder, and onion powder. Rub the seasoning all over the roast.

  2. 2

    Roast the Prime Rib

    Place the seasoned prime rib roast on a roasting pan. Roast in the preheated oven for about 1.5 to 2 hours or until the internal temperature reaches 130°F (54°C) for medium-rare. Remove from the oven and let it rest for 20 minutes.

  3. 3

    Slice the Prime Rib

    Once rested, thinly slice the prime rib against the grain using a sharp knife.

  4. 4

    Prepare the Rolls

    Slice the French rolls in half and place them on a baking sheet. Layer the sliced prime rib on the bottom half of each roll and top with Monterey Jack cheese.

  5. 5

    Melt the Cheese

    Place the baking sheet in the oven for 5-7 minutes or until the cheese is melted and bubbly. Remove from the oven.

For the Au Jus

  1. 6

    Make the Au Jus

    In a saucepan, combine the beef broth, Worcestershire sauce, minced garlic, and fresh thyme. Bring to a simmer over medium heat.

  2. 7

    Season the Au Jus

    Allow to simmer for about 10 minutes. Season with salt and black pepper to taste, adjusting the flavors as needed.
