Method

Steak Preparation

  1. 1

    Marinade the Flank Steak

    In a bowl, combine olive oil, garlic powder, paprika, salt, and black pepper. Rub this mixture all over the flank steak. Let it marinate for at least 30 minutes, or up to overnight in the refrigerator for more flavor.

  2. 2

    Grill the Steak

    Preheat your grill to medium-high heat. Grill the marinated flank steak for about 5-7 minutes per side, or until it reaches your desired doneness. Remove from the grill and let it rest for 10 minutes before slicing.

Vegetable Preparation

  1. 3

    Sauté the Vegetables

    While the steak is resting, slice the onion, bell pepper, and mushrooms. In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the sliced vegetables and sauté for about 5-7 minutes, or until they are tender and slightly caramelized. Set aside.

Fried Onion Strings

  1. 4

    Prepare the Onions

    Slice the large onion into thin rings and soak them in buttermilk for at least 30 minutes.

  2. 5

    Fry the Onion Strings

    In a separate bowl, combine all-purpose flour, cornstarch, salt, and black pepper. Heat vegetable oil in a deep frying pan over medium-high heat. Remove the onion rings from the buttermilk, dredge them in the flour mixture, and fry them in batches until they are golden brown, approximately 2-3 minutes per batch. Drain on paper towels.

Assembly

  1. 6

    Assemble the Cowboy Flank Steak

    Slice the rested flank steak against the grain. Top with the sautéed vegetables and a generous handful of fried onion strings. Serve hot.
