Ingredients
  

For the Balsamic Marinade/Dressing

  • 1/4 cup balsamic vinegar
  • 1/4 cup extra virgin olive oil
  • 1 tablespoon Dijon mustard
  • 1 teaspoon honey
  • 1 large garlic clove minced or grated
  • 1/4 teaspoon salt
  • 1/4 teaspoon black pepper

For the Steak Caprese

  • 2 pounds flank steak
  • 2 cups cherry or grape tomatoes
  • 1 cup fresh buffalo mozzarella diced
  • 2 tablespoons fresh basil thinly sliced

Instructions
 

  • In a bowl, whisk together the balsamic vinegar, olive oil, Dijon mustard, honey, garlic, salt, and pepper until smooth.
  • Reserve half of the dressing for serving and pour the remaining half over the flank steak.
  • Cover and refrigerate overnight, allowing the steak to fully absorb the flavors.
  • Remove the steak from the marinade and gently shake off any excess.
  • Grill over medium-high heat for 3–5 minutes per side, or until your preferred level of doneness. This Balsamic Grilled Flank Steak is best served medium-rare to medium.
  • Transfer the steak to a cutting board and let it rest for 5 minutes.
  • Grill the cherry tomatoes for 3–5 minutes until lightly blistered. Alternatively, blister them in a hot skillet.
  • Slice the steak thinly against the grain.
  • Arrange on a serving platter and top with the grilled tomatoes, diced mozzarella, fresh basil, and the reserved balsamic dressing.
  • Serve immediately while warm.

Notes

  • Fresh mozzarella provides the best creamy texture.
  • Grape tomatoes work just as well as cherry tomatoes.
  • Leftover steak is excellent in sandwiches, wraps, salads, or grain bowls.
  • Pair with grilled vegetables, roasted potatoes, garlic bread, or a crisp green salad
