Steak Sandwich

Sauteed Onions and Mushrooms

French Fries

Method

Preparing the French Fries

  1. 1

    Cut the Potatoes

    Wash and peel the potatoes. Cut them into even-sized sticks, about 1/4 inch thick.

  2. 2

    Soak the Fries

    Soak the cut potatoes in cold water for at least 30 minutes to remove excess starch, then drain and pat dry.

  3. 3

    Heat the Oil

    In a deep pot or fryer, heat the vegetable oil to 350°F (175°C).

  4. 4

    Fry the Potatoes

    Fry the potatoes in batches for about 5-7 minutes or until golden brown and crispy. Remove and drain on paper towels. Season with salt.

Cooking the Steak

  1. 5

    Season the Steak

    Rub the flank steak with olive oil, salt, and black pepper.

  2. 6

    Cook the Steak

    Heat a grill or skillet over medium-high heat. Cook the steak for approximately 4-5 minutes on each side for medium-rare. Let it rest for 5 minutes, then slice thinly against the grain.

Sauteing Onions and Mushrooms

  1. 7

    Prepare Vegetables

    Slice the onion thinly and chop the garlic. Clean and slice the cremini mushrooms.

  2. 8

    Saute the Onions and Mushrooms

    In a skillet, melt the butter over medium heat. Add the onions and sauté for 5 minutes until translucent. Add the mushrooms and garlic, cooking for another 5-7 minutes until the mushrooms are tender and browned.

Assembling the Sandwich

  1. 9

    Prepare the Bread

    Toast the sourdough bread slices until golden brown.

  2. 10

    Build the Sandwich

    On each slice of toasted sourdough, layer slices of steak, followed by the sautéed onions and mushrooms. Top with smoked gouda cheese.

  3. 11

    Melt the Cheese

    You can place the assembled sandwiches under a broiler for 2-3 minutes until the cheese melts and starts to bubble.
