Why You’ll Love This Recipe

This Mouthwatering Balsamic Flank Steak will quickly become a favorite in your recipe collection for so many reasons.

Ingredients

For the Mouthwatering Balsamic Flank Steak:

• 1½-2 lbs (680-900g) flank steak
• ½ cup (120ml) high-quality balsamic vinegar (aged varieties provide deeper flavor)
• ¼ cup (60ml) extra virgin olive oil
• 3 tablespoons (45ml) honey or brown sugar
• 4 cloves garlic, minced (about 2 tablespoons)
• 2 tablespoons fresh rosemary, chopped
• 1 tablespoon fresh thyme leaves
• 1 tablespoon Dijon mustard
• 1 teaspoon kosher salt
• ½ teaspoon freshly ground black pepper
• ¼ teaspoon red pepper flakes (optional, for heat)

The balsamic vinegar is the star ingredient here—its natural sugars caramelize beautifully during cooking, creating a mouthwatering crust on the steak. Whenever possible, use a higher-quality balsamic, as it will have a more complex flavor profile that really elevates this flank steak with balsamic glaze.

Pro Tips

Choose the Right Cut: While this recipe calls for flank steak, you can also use skirt steak or hanger steak with excellent results. These cuts share similar characteristics and respond beautifully to the balsamic marinade for steak. Just be sure to adjust cooking times slightly based on thickness.

Marinade Magic: For maximum flavor penetration, score the surface of your flank steak with shallow diagonal cuts (about ¼ inch deep) in a diamond pattern before marinating. This allows the balsamic steak marinade to penetrate deeper into the meat fibers. For best results, marinate for at least 4 hours, but preferably overnight—this makes a dramatic difference in both flavor and tenderness.

Perfect Cooking Temperature: The secret to perfectly cooked Mouthwatering Balsamic Flank Steak is high heat and accurate timing. Flank steak is best served medium-rare to medium (130-145°F internal temperature). Use a meat thermometer for precision, and always let the steak rest for at least 10 minutes before slicing to allow juices to redistribute throughout the meat.

Instructions

Step 1: Prepare the Marinade
In a medium bowl, whisk together the balsamic vinegar, olive oil, honey, minced garlic, rosemary, thyme, Dijon mustard, salt, pepper, and red pepper flakes until well combined. The marinade should look glossy and emulsified. Set aside 3 tablespoons of the mixture in a separate container for basting during cooking.

Step 2: Prepare the Steak
Pat the flank steak dry with paper towels. Using a sharp knife, score the surface of the steak in a diamond pattern, making shallow cuts about ¼ inch deep on both sides. This helps the marinade penetrate the meat for more flavor and tenderness.

Step 3: Marinate
Place the steak in a large resealable plastic bag or shallow dish and pour the remaining marinade over it. Turn the steak several times to ensure it’s well-coated. Seal the bag or cover the dish and refrigerate for at least 4 hours, preferably overnight, turning occasionally if possible.

Step 4: Prepare for Cooking
Remove the steak from the refrigerator 30-45 minutes before cooking to allow it to come to room temperature. This ensures more even cooking. Preheat your grill to high heat (approximately 450-500°F) or heat a cast-iron skillet over high heat until smoking hot.

Step 5: Grill the Steak
Remove the steak from the marinade, letting excess drip off. Discard the used marinade. Place the steak on the hot grill or skillet and cook for 4-5 minutes on the first side without moving it. This allows a beautiful crust to form. Flip once and cook for another 3-4 minutes for medium-rare, or longer to your preferred doneness. During the last minute of cooking, brush with the reserved marinade for an extra flavor boost.

Step 6: Rest and Slice
Transfer the Mouthwatering Balsamic Flank Steak to a cutting board and tent loosely with foil. Allow it to rest for 10 minutes—this step is crucial for juicy results. After resting, slice the steak thinly against the grain at a slight angle. This cuts through the muscle fibers, ensuring tenderness with each bite.

Variations

Asian-Inspired Balsamic Flank Steak: Create an exciting fusion by adding 2 tablespoons of soy sauce, 1 tablespoon of grated ginger, and 1 teaspoon of sesame oil to the marinade. This variation complements the balsamic steak beautifully while adding complex umami notes. Garnish with sliced green onions and sesame seeds before serving.

Herb-Intensified Version: For herb lovers, double the fresh herbs and add 2 tablespoons of fresh basil and 1 tablespoon of oregano to the original marinade. This Mediterranean-inspired variation enhances the aromatic profile of the Mouthwatering Balsamic Flank Steak and pairs wonderfully with grilled vegetables.

Spicy Balsamic Flank: If you enjoy heat, transform this into a spicy delight by adding 1 tablespoon of chipotle in adobo sauce and doubling the red pepper flakes in the marinade. The smokiness of the chipotle complements the sweetness of the balsamic, creating a more complex flavor profile for your balsamic marinade for steak.

Storage and Serving

Storage: Properly stored, cooked Balsamic Flank Steak will keep in the refrigerator for 3-4 days. For best results, store the sliced steak in an airtight container with any accumulated juices to help maintain moisture. You can also freeze the cooked steak for up to 2-3 months, though the texture may change slightly upon thawing.

Reheating: To prevent the Mouthwatering Balsamic Flank Steak from becoming tough when reheating, warm it gently. Either microwave on 50% power with a damp paper towel over the meat, or place in a covered skillet with a tablespoon of water or beef broth over low heat just until warmed through.

Serving Suggestions: This versatile steak shines in numerous presentations. Serve it as the centerpiece of a meal with roasted potatoes and grilled asparagus for an elegant dinner. For a more casual option, thinly slice the balsamic steak and use in sandwiches with caramelized onions and blue cheese. It also makes an outstanding addition to salads—try it over arugula with shaved parmesan, pine nuts, and a light vinaigrette for a satisfying lunch.
