1-Marinate the steak for deep flavor: Start by whisking together 2 tablespoons olive oil, 2 tablespoons balsamic vinegar, honey, minced garlic, dried oregano, 1 teaspoon kosher salt, and 1/2 teaspoon pepper in a bowl or a resealable bag. This simple marinade is what gives Grilled Balsamic Steak Caprese its sweet, savory flavor. Place the flank steak in the bag, pour in the marinade, seal it well, and refrigerate for 2 to 12 hours. For best flavor, let it sit at least 2 hours, but do not go past 12 hours or the meat can turn soft. While the steak marinates, you can get the caprese topping ready. Combine the halved cherry tomatoes, drained mozzarella pearls, remaining olive oil, remaining balsamic vinegar, remaining salt, remaining pepper, and chopped fresh basil in a bowl. Toss gently so the cheese stays whole and the tomatoes stay juicy. Cover and refrigerate until you are ready to grill.

2-Preheat the grill and cook the steak: About 20 minutes before cooking, remove the steak from the fridge so it can warm slightly. This helps it cook more evenly on the grill. Preheat your grill to 500 degrees F, then oil the grates well to keep the steak from sticking. A hot grill is the key to good color and a nice sear on Grilled Balsamic Steak Caprese. Take the steak out of the marinade and pat it dry with paper towels. Drying the surface helps the steak brown better. Place it on the grill and cook for 6 to 8 minutes per side, depending on thickness and your preferred doneness. For medium rare, aim for 130 degrees F on a meat thermometer. This step matters because it gives you juicy steak instead of overcooked steak.

3-Rest, slice, and assemble: When the steak is done, transfer it to a pan and cover it loosely with foil. Let it rest for 5 to 10 minutes so the juices stay inside the meat. This resting step is easy to skip, but it makes a big difference in tenderness. After resting, slice the flank steak against the grain. Thin slices are best for this dish because they are easier to chew and look beautiful on the platter. Arrange the sliced steak on a serving platter. Spoon the caprese salad over the top or around the steak, depending on how you want to serve it. Add whole basil leaves for garnish, then drizzle with balsamic glaze if you want extra sweetness and shine. Serve right away while the steak is still warm and the tomato mozzarella mixture is cool and fresh.
