Method

Beef Roast Preparation

  1. 1

    Preheat the Oven

    Preheat your oven to 325°F (160°C).

  2. 2

    Season the Beef

    Rub the beef roast with olive oil, salt, black pepper, garlic powder, and onion powder. Make sure to cover it evenly on all sides.

  3. 3

    Sear the Beef

    In a large skillet, heat a bit of oil over medium-high heat. Sear the beef roast on all sides until browned, about 3-4 minutes per side.

  4. 4

    Roast the Beef

    Transfer the seared beef to a roasting pan. Pour the beef broth around the roast. Cover with aluminum foil and roast in the preheated oven for about 1.5 to 2 hours, or until the internal temperature reaches your desired doneness (medium rare is 135°F/57°C).

  5. 5

    Rest the Beef

    Once done, remove the roast from the oven and let it rest for at least 15 minutes before slicing.

Horseradish Sauce Preparation

  1. 6

    Mix the Sauce

    In a medium bowl, combine prepared horseradish, mayonnaise, and lemon juice. Whisk until smooth and well-blended. Refrigerate until ready to use.

Sandwich Assembly

  1. 7

    Slice the Bread

    Slice the French bread loaf in half horizontally.

  2. 8

    Assemble the Sandwich

    Layer slices of the roast beef evenly on the bottom half of the bread. Spread a generous amount of horseradish sauce over the beef. Top with a handful of Frenchie's crispy onions.

  3. 9

    Finish the Sandwich

    Place the top half of the bread over the fillings. Press down gently and cut into individual sandwiches.
