- 1/4 cup soy sauce – Provides a savory depth that complements the sweetness of the honey.
- 2 tablespoons honey – Balances the acidity with a touch of sweetness, enhancing the overall flavor profile.
- 2 cloves garlic (minced) – Fresh garlic infuses aromatic goodness, elevating your marinade’s taste.
- 1 teaspoon black pepper (freshly ground) – Adds a nice kick and enhances all the other flavors beautifully.
- 1 teaspoon salt – Essential for bringing out the natural flavors of the steak and marinade.

For the Steak

Steps to Create a Flavorful Flank Dish
1. Whisk Together Marinade: In a mixing bowl, whisk together 1/2 cup balsamic vinegar, 1/4 cup soy sauce, 2 tablespoons honey, minced garlic from 2 cloves, 1 teaspoon freshly ground black pepper, 1 teaspoon salt, and 2 tablespoons olive oil. This mixture will infuse the steak with rich flavors.
2. Marinate the Steak: Place 1.5 pounds of trimmed flank steak in a resealable plastic bag and pour the marinade over it. Seal the bag and refrigerate for at least 1 hour or up to overnight. This allows the steak to absorb all those delicious flavors.
3. Preheat the Grill: Preheat your grill to medium-high heat, which ensures that your steak cooks evenly and gets those beautiful grill marks. Aim for about 400°F for optimal grilling.
4. Discard Marinade: Remove the flank steak from the marinade and discard the marinade. This step prevents any burning on the grill while maximizing flavor.
5. Grill the Steak: Grill the steak for about 5-7 minutes on each side or until it reaches your desired doneness (130°F for medium-rare). Look for a nice char and juices bubbling through.
6. Let It Rest: Remove from the grill and let the steak rest for 5 minutes before slicing against the grain. Resting helps retain all those juicy flavors inside!
Optional: Serve with fresh herbs or a sprinkle of sea salt for an extra touch.
