Method

Preparation Steps

  1. 1

    Prepare the Steak

    Season the strip steak with salt and black pepper. Heat 1 tablespoon of olive oil in a grill pan over medium-high heat. Grill the steak for about 4-5 minutes on each side for medium-rare, or until desired doneness is reached. Remove from heat and let it rest for 5 minutes before slicing.

  2. 2

    Sauté the Vegetables

    In the same grill pan, add 1 tablespoon of olive oil and sauté the sliced red onion and button mushrooms until they are soft and browned, about 5-7 minutes.

  3. 3

    Assemble the Sandwich

    Slice the ciabatta bread in half and place one half on a baking sheet. Layer the sliced steak, sautéed mushrooms, and onions. Top with provolone and gruyere cheese. Place the other half of the bread on top.

  4. 4

    Toast the Sandwich

    Preheat the oven to 375°F (190°C). Bake the sandwich for about 10 minutes or until the cheese is melted and the bread is toasted.

  5. 5

    Serve

    Slice the sandwich in half and serve warm with creamy horseradish sauce on the side.
