Ingredients

For the Balsamic Marinade:

  • 1/3 cup balsamic vinegar
  • 1/3 cup extra virgin olive oil
  • 1 tbsp Dijon mustard
  • 1 tbsp honey
  • 2 cloves garlic, minced
  • 1 tsp salt
  • 1/2 tsp pepper

For the Balsamic Glaze:

  • 1/2 cup balsamic vinegar
  • 2 tbsp brown sugar

For the Steak Caprese:

  • 1 1/2 pounds flank steak
  • 2 cups cherry or grape tomatoes, halved or quartered
  • 1 cup fresh mozzarella pearls, halved
  • 2 tbsp fresh basil, thinly sliced
  • 2 tbsp prepared balsamic glaze

Instructions

1. Marinade Magic:
Whisk together all the marinade ingredients in a bowl. Then let your flank steak take a soak in half of that delicious mixture overnight in the fridge. The longer it marinates, the better — but if you’re short on time, a few hours will do the trick.

2. Prepare Balsamic Glaze:
Pour balsamic vinegar and brown sugar into a small saucepan over medium heat. Bring to a gentle boil, then reduce and simmer until it’s thickened and syrupy, about 6–8 minutes. Set it aside to cool and work its magic.

3. Caprese Topping:
Mix the tomatoes, mozzarella, basil, and about a tablespoon of your balsamic glaze in a bowl. You’re basically building flavor fireworks here.

4. Grill It Up:
Shake off the excess marinade and grill your steak over medium-high heat. Cook for 3–5 minutes per side, depending on how you like your steak. Let it rest for 5 minutes before slicing thinly against the grain.

5. Assemble and Enjoy:
Pile the steak slices on a platter, top generously with that fresh Caprese mixture, and drizzle with balsamic glaze. Voilà! Dinner is served.

Pro Tips

  • Marinate for maximum flavor: Overnight is ideal, but even a couple of hours make a difference.
  • The balsamic glaze can be made up to two days ahead—simply keep it chilled in the refrigerator until you’re ready to use.
  • Cheese swap: No fresh mozzarella pearls? No worries! Regular fresh mozzarella cut into bite-sized pieces works beautifully.
  • Herb upgrade: Add oregano or parsley if you want to shake things up.
  • No grill? No problem! Use a grill pan or cast-iron skillet to get those lovely char marks.
  • Veggie add-ons: Grilled bell peppers or zucchini are great companions here.

Pairing Suggestions

  • Grilled Asparagus with a squeeze of lemon and a sprinkle of Parmesan — simple and elegant.
  • Watermelon, Feta & Mint Salad — sweet, juicy watermelon with salty feta and refreshing mint is a summer classic.
  • Charred Corn Salad — sweet corn grilled until smoky, tossed with lime juice, chili powder, and cilantro.
  • Herbed Quinoa — nutty and fluffy with fresh herbs like parsley, mint, and a touch of lemon zest.
  • Garlic Roasted Baby Potatoes — crispy, golden, and perfect for soaking up that balsamic glaze.
