Ingredients for Marinated Flank Steak
- 1 ½ to 2 pounds flank steak
- ½ cup soy sauce
- ¼ cup olive oil
- 3 tablespoons balsamic vinegar
- 3 cloves garlic, minced
- 2 tablespoons brown sugar or honey
- 1 teaspoon Dijon mustard
- 1 teaspoon freshly ground black pepper
- ½ teaspoon red pepper flakes (optional, for heat)
- 2 tablespoons fresh chopped herbs (such as parsley or rosemary)
👉 Tip: Use fresh garlic and herbs when possible for the boldest flavor.
Instructions
- Prepare the Marinade
In a medium bowl, whisk together the soy sauce, olive oil, balsamic vinegar, garlic, brown sugar, Dijon mustard, pepper, and red pepper flakes. - Marinate the Flank Steak
Place the steak in a large resealable plastic bag or shallow dish. Pour the marinade over it, making sure the steak is well coated. Seal the bag or cover the dish and refrigerate for at least 2 hours, ideally overnight for maximum flavor. - Preheat the Grill
When ready to cook, remove the steak from the refrigerator and let it come to room temperature. Preheat your grill to medium-high heat (about 400°F). - Grill the Steak
Remove the steak from the marinade and pat it dry with paper towels. Grill for 4–6 minutes per side for medium-rare, or longer if desired. - Rest and Slice
Let the steak rest for 5 minutes before slicing. Always cut against the grain into thin strips for the most tender bites.
Why Marinated Flank Steak Works So Well
The beauty of this recipe lies in how the marinade transforms the meat. Flank steak is naturally lean, which makes it flavorful but sometimes tough. The combination of soy sauce and balsamic vinegar helps tenderize the fibers, while olive oil locks in juiciness. Garlic, mustard, and herbs build complexity, and a touch of sugar balances everything with subtle sweetness.
When grilled properly and sliced thinly, flank steak becomes tender, juicy, and bursting with flavor.

Tips for the Best Results
- Marinate overnight for maximum flavor penetration.

- Always slice against the grain. This shortens the muscle fibers, creating tender bites.
- Rest the steak before slicing so juices redistribute evenly.
Additional Tips for Perfecting Your Marinated Flank Steak
Even the best recipe benefits from a few pro tips. First, always marinate for at least 4 hours, though overnight yields the richest flavor. Be sure to slice your marinated flank steak thinly against the grain, which shortens the muscle fibers and makes each bite tender. For grilling, preheat the grill to high heat and sear each side for just a few minutes. The goal is to achieve a crisp, caramelized outside while keeping the inside juicy. Resting the steak for 5-10 minutes before slicing locks in those savory juices. With these techniques, your marinated flank steak becomes a show-stopping centerpiece for any meal.
