1.5 to 2 pounds flank steak
1/4 cup balsamic vinegar
2 tablespoons olive oil
2 teaspoons Dijon mustard
3 cloves garlic, minced
1 tablespoon fresh rosemary, chopped (or 1 teaspoon dried)
Salt and freshly ground black pepper to taste
Caprese Topping
2 large vine-ripened tomatoes, sliced
8 ounces fresh mozzarella, sliced
1/2 cup fresh basil leaves
1 tablespoon olive oil
Salt and pepper to taste
Balsamic Glaze (optional but recommended)
1/2 cup balsamic vinegar
1 tablespoon honey or brown sugar
In a bowl, whisk together balsamic vinegar, olive oil, Dijon mustard, garlic, rosemary, salt, and pepper. Place the flank steak in a zip-top bag or shallow dish, pour in the marinade, and coat evenly. Refrigerate for at least 30 minutes, up to 4 hours.
To make the balsamic glaze, simmer 1/2 cup balsamic vinegar with 1 tablespoon honey or brown sugar in a small saucepan over medium heat. Reduce heat and simmer for 10–15 minutes until thickened. Set aside to cool.
Preheat a gas or charcoal grill to medium-high heat. Lightly oil the grates to prevent sticking.
Remove steak from marinade, letting excess drip off. Grill for 5–7 minutes per side, or until internal temperature reaches 130°F for medium-rare or 140°F for medium.
Transfer steak to a cutting board, tent with foil, and rest for 10 minutes.
While the steak rests, layer sliced tomatoes, mozzarella, and fresh basil. Drizzle with olive oil, and season with salt and pepper.
Slice the steak thinly against the grain. Arrange on a serving platter and top with the Caprese mixture. Drizzle with balsamic glaze. Serve immediately.
Always slice flank steak against the grain to ensure tenderness.
You can substitute chicken breast for a lighter version.
Burrata can replace mozzarella for a richer topping.
Use heirloom tomatoes for added color and flavor.
