Recipe Information
Ingredients
- 1 pound flank steak
- 2 tablespoons olive oil
- 3 tablespoons soy sauce
- 2 tablespoons Worcestershire sauce
- 3 garlic cloves, minced
- 1 teaspoon smoked paprika
- 1 teaspoon ground black pepper
- 4 ciabatta rolls
- 1 yellow onion, sliced
- 2 tablespoons unsalted butter
- 0.5 cup mayonnaise
- 2 tablespoons prepared horseradish
- 1 cup baby arugula
- 1 teaspoon salt
- 1 teaspoon black pepper
Instructions
In a large resealable plastic bag, combine olive oil, soy sauce, Worcestershire sauce, minced garlic, smoked paprika, and ground black pepper. Add flank steak to the bag, seal, and massage the marinade into the meat. Refrigerate for at least 1 hour, or up to overnight for maximum flavor.
Heat a large skillet or grill pan over medium-high heat. Remove the flank steak from the marinade, letting excess drip off. Cook steak for 4-5 minutes per side for medium-rare, or until it reaches your desired level of doneness. Set aside, cover loosely with foil, and let rest for 10 minutes.
While the steak rests, heat the butter in a large skillet over medium heat. Add sliced onions and a pinch of salt, stirring occasionally, and cook for 15-20 minutes until onions are deeply caramelized. Remove from heat and set aside.
In a small bowl, mix mayonnaise and horseradish together to create the horseradish mayo. Adjust seasoning with a pinch of salt if needed.
Slice the rested flank steak thinly against the grain into strips.
Slice the ciabatta rolls horizontally and lightly toast them in a hot, dry skillet or under a broiler for 1-2 minutes.
Assemble the sandwiches by spreading horseradish mayo on the bottom halves of the rolls. Layer with baby arugula, sliced steak, caramelized onions, and more horseradish mayo (if desired). Top with the other half of the roll.
Serve immediately with your favorite side, like fries or a simple salad. Enjoy!
