Beef and Au Jus

Onions and Cheese

Bread and Fries

Method

Preparing the Beef and Au Jus

  1. 1

    Roasting the Beef

    Preheat your oven to 350°F (175°C). Season the prime beef roast with salt and black pepper. Place it in a roasting pan and roast for approximately 1.5 hours, or until it reaches your desired doneness.

  2. 2

    Making the Au Jus

    In a pot, combine the beef broth, minced garlic, bay leaves, and any drippings from the roast. Bring to a simmer and cook for 15-20 minutes to allow flavors to meld.

Caramelizing the Onions

  1. 3

    Sautéing the Onions

    In a skillet, melt the butter over medium heat. Slice the onions and add them to the skillet. Cook, stirring occasionally, until they are caramelized and golden brown, about 20-25 minutes.

Preparing the Fries

  1. 4

    Making Kennebec Fries

    Cut the Kennebec potatoes into fries. In a large bowl, toss the fries with olive oil and salt. Arrange them on a baking sheet and bake in the oven at 425°F (220°C) for 30-35 minutes, turning occasionally, until crispy.

Assembling the French Dip

  1. 5

    Final Assembly

    Slice the roasted beef thinly. Layer the beef on the ciabatta rolls, top with caramelized onions and cave-aged cheddar. Serve with the warm au jus on the side for dipping and the fries on the side.
