Flank Steak and Accompaniments

Method

Cooking Instructions

  1. 1

    Prepare the Flank Steak

    Preheat your grill or grill pan to high heat. Rub the flank steak with olive oil, salt, black pepper, and garlic powder on both sides.

  2. 2

    Grill the Flank Steak

    Place the steak on the grill and cook for about 5-7 minutes on each side for medium rare, or until the internal temperature reaches 130°F (54°C). Remove from grill and let rest for 10 minutes before slicing.

  3. 3

    Make the Mushroom Sauce

    In a skillet, melt butter over medium heat. Add sliced mushrooms and sauté until they are browned, about 5 minutes. Pour in the heavy cream, and stir until the sauce thickens. Season with salt and pepper to taste.

  4. 4

    Prepare the House Salad

    In a large bowl, combine mixed greens, cherry tomatoes, and cucumber. In a small bowl, whisk together olive oil, balsamic vinegar, salt, and pepper. Drizzle the dressing over the salad and toss to combine.

  5. 5

    Serve

    Slice the flank steak against the grain and serve with mushroom sauce, chips, and house salad on the side.
