Flank steak is a lean cut of beef that has a lot of flavor and texture.
Flank steak benefits from a marinade that tenderizes and seasons it. A soy-based marinade with garlic, ginger, and mustard is a classic choice that works well with the beefy flavor of the steak.
Flank steak should be cooked quickly over high heat to avoid overcooking and toughening. It can be grilled, broiled, or pan-seared for about 6 to 8 minutes per side, depending on the thickness and desired doneness.
Flank steak should be sliced thinly across the grain to make it easier to chew and enjoy. It can be served on French rolls, ciabatta, or any bread of your choice, along with grilled vegetables, cheese, and a creamy horseradish sauce.
You can also make it into a salad, a wrap, or a bowl for a low-carb option.
Marinated Flank Steak Sandwich Recipe Ingredients and Steps
Quick reference summary (serves 6)
1 beef flank steak (about 1.5 pounds or 680 grams)
1 cup chopped onion
1 cup dry red wine or beef broth
3/4 cup reduced-sodium soy sauce
1/2 cup olive oil, divided
4 1/2 teaspoons minced garlic, divided
1 1/2 teaspoons ground mustard
1 1/2 teaspoons ground ginger
1 medium sweet red pepper, cut into 1-inch strips
1 medium sweet yellow pepper, cut into 1-inch strips
1 medium red onion, thickly sliced
1/4 teaspoon pepper
6 French rolls, split
6 slices of cheese of your choice (optional)
1/4 cup mayonnaise
2 tablespoons sour cream
2 teaspoons prepared horseradish
Sliced tomatoes (optional)
- In a small bowl, whisk together the onion, wine, soy sauce, 1/4 cup olive oil, 2 1/2 teaspoons garlic, mustard, and ginger. Pour 1 3/4 cups of the marinade into a shallow dish or a resealable plastic bag; add the steak and turn to coat. Cover or seal and refrigerate for at least 3 hours or up to overnight, turning occasionally. Pour the remaining marinade into another shallow dish or a resealable plastic bag; add the peppers and onion and turn to coat. Cover or seal and refrigerate for at least 3 hours or up to overnight, turning occasionally.
- Preheat a grill to medium-high heat or a broiler to high. Drain and discard the marinade from the steak and the vegetables. Lightly oil the grill rack or a baking sheet. Grill or broil the steak for 6 to 7 minutes per side or until it reaches your preferred doneness (125°F or 52°C for rare, 130°F or 54°C for medium-rare, 135°F or 57°C for medium). Transfer the steak to a cutting board and let it rest for 10 minutes before slicing thinly across the grain.
- Grill or broil the vegetables for 9 to 11 minutes or until tender, stirring or turning frequently. In a small bowl, whisk together the pepper, the remaining oil and garlic; brush over the cut sides of the rolls. Grill or broil the rolls for 2 to 3 minutes or until golden brown. In another small bowl, whisk together the mayonnaise, sour cream, and horseradish.
- To assemble the sandwiches, layer each roll bottom with some steak, cheese (if using), vegetables, and tomatoes (if using). Spread some horseradish sauce over the roll tops and place them over the sandwiches. Serve immediately or wrap and refrigerate for later.
Flank Steak Sandwich Variations and Ideas
You can customize your flank steak sandwich by using different marinades, sauces, cheeses, and vegetables. Here are some suggestions:
- For an Asian-inspired marinade, use sesame oil, rice vinegar, honey, garlic, ginger, and sriracha sauce instead of the wine, soy sauce, mustard, and ginger.
- For a Greek-inspired marinade, use olive oil, lemon juice, red wine vinegar, garlic, oregano, and black pepper instead of the wine, soy sauce, mustard, and ginger.
- For a Mexican-inspired marinade, use lime juice, chili powder, cumin, garlic, and cilantro instead of the wine, soy sauce, mustard, and ginger.
- For a different sauce, try barbecue sauce, pesto, salsa, or chimichurri instead of the horseradish sauce.
- For a different cheese, try Swiss, cheddar, provolone, or mozzarella instead of the cheese of your choice.
- For different vegetables, try mushrooms, zucchini, eggplant, or asparagus instead of the peppers and onion.
You can also make your flank steak sandwich into a salad, a wrap, or a bowl for a low-carb option. Just skip the bread and cheese and toss the steak and vegetables with some lettuce, spinach, or kale.
Drizzle some horseradish sauce or dressing of your choice over the salad. Alternatively, you can wrap the steak and vegetables in a tortilla, a lettuce leaf, or a low-carb wrap.
Or, you can serve the steak and vegetables over some rice, quinoa, cauliflower rice, or mashed potatoes.

Flank Steak Sandwich FAQ
Flank steak is a lean and economical cut of beef that comes from the abdominal muscles of the cow. It has a lot of flavor and texture, but it can be tough if overcooked. It is best cooked quickly over high heat and sliced thinly across the grain.
One of the best ways to tenderize flank steak is to marinate it in a mixture of acidic, salty, and flavorful ingredients. The acid helps to break down the tough fibers of the meat, while the salt and flavorings season and enhance it. You can also pound the steak with a meat mallet to make it more even and tender.
The best way to know when flank steak is done is to use a meat thermometer and check the internal temperature of the thickest part of the steak. For rare, the temperature should be 125°F or 52°C; for medium-rare, 130°F or 54°C; for medium, 135°F or 57°C. You can also use the touch test and press the steak with your finger. If it feels soft and squishy, it is rare; if it feels firm and springy, it is medium; if it feels hard and tight, it is well done.
