A great flank steak marinade is important if you want a tender, juicy, flavorful steak. For best results, marinate your steak for at least 2 hours or longer if you have time.

Why This Flank Steak Marinade Works

We’ve tested countless steak marinade recipes, and this one strikes the perfect balance between acidity, umami, and richness. The combination of soy sauce, balsamic vinegar, and aromatics ensures deep flavor penetration, while the oil helps keep the steak moist during grilling.

Ingredients for Your Flank Steak Marinade

• ½ cup vegetable oil
• ½ cup soy sauce
• ¼ cup balsamic vinegar
• 3 cloves garlic, minced
• 2 tbsp Worcestershire sauce
• 1 tbsp Dijon mustard
• 1 tsp freshly ground black pepper
• 1 tsp red pepper flakes (optional)
• 1.5–2 lb flank steak

Step-by-Step Instructions

1. Gather Your Gear: Make sure you have a large resealable plastic bag or shallow dish, a whisk, and measuring cups.
2. Mix the Marinade: In a medium bowl, whisk together vegetable oil, soy sauce, balsamic vinegar, garlic, Worcestershire sauce, Dijon mustard, black pepper, and red pepper flakes.
3. Marinate the Steak: Place the flank steak in your bag or dish. Pour the marinade over the meat, ensuring it’s fully coated. Seal or cover, then refrigerate.
4. Chill & Infuse: Let the steak marinate for at least 2 hours, or up to 8 hours for maximum tenderness and flavor.
5. Preheat the Grill: When ready, heat your grill to medium-high (about 400°F). Oil the grates lightly to prevent sticking.
6. Grill to Perfection: Remove steak from marinade, allow excess to drip off, then place on the hot grill. Cook 5–7 minutes per side for medium-rare, or adjust to your preferred doneness.
7. Rest & Slice: Transfer steak to a cutting board and let rest for 10 minutes. Slice thinly against the grain to ensure tenderness.
8. Serve & Enjoy: Arrange slices on a platter, garnish with fresh herbs, and serve with your favorite sides.

Expert Tips & Variations

• Reserve a Little Marinade: Set aside a few tablespoons before adding the steak to drizzle over when plating.
• For a citrus twist, swap balsamic vinegar for fresh lime or orange juice.
• Use a cast-iron skillet indoors if the weather keeps you from grilling.
• Let steak sit at room temperature for 20 minutes before cooking to promote even grilling.
