Ingredients

Serves 4

• 1 1/2 to 2 pounds flank steak, trimmed
• 1/3 cup balsamic vinegar
• 1/4 cup extra-virgin olive oil
• 2 tablespoons honey or maple syrup
• 3 cloves garlic, minced
• 1 teaspoon Dijon mustard
• 1 teaspoon dried oregano or 1 tablespoon fresh, chopped
• 1/2 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon freshly ground black pepper
• 8 ounces fresh mozzarella, sliced
• 2 cups grape or cherry tomatoes, halved (or 2 large tomatoes, sliced)
• 1 cup fresh basil leaves
• Balsamic glaze (store-bought or homemade) for drizzling
• Optional: flaky sea salt for finishing

Notes: Want a lighter balsamic steak recipe? Use less oil or swap honey for a sugar-free sweetener. For a touch of heat, add a pinch of red pepper flakes to the marinade.

Step-by-Step: How to Make Balsamic Grilled Flank Steak Caprese

1. Make the marinade. In a medium bowl, whisk together the balsamic vinegar, olive oil, honey, minced garlic, Dijon, oregano, salt, and pepper. This simple mixture does the heavy lifting for flavor — no fuss, big payoff.

2. Marinate the flank steak. Place the flank steak in a resealable bag or shallow dish and pour the marinade over it. Massage the marinade into the meat so every inch gets some love. Let it sit at least 30 minutes at room temperature, or up to 4 hours in the fridge. Pro tip: if you’re short on time, 30 minutes still gives plenty of flavor.

3. Prep your grill. Preheat your grill to medium-high (about 400–450°F). If using a grill pan or cast iron on the stove, heat it until it’s shimmering hot. Oil the grill grates or the pan lightly to prevent sticking.

4. Grill the steak. Remove steak from the marinade and let excess drip off (discard remaining marinade). Grill the steak 4–6 minutes per side for medium-rare, depending on thickness — flank steak is lean and benefits from a quick, hot sear. Use an instant-read thermometer: 125–130°F for medium-rare, 135°F for medium.

5. Rest, then slice. Transfer the steak to a cutting board and tent loosely with foil. Rest for 10 minutes to let the juices redistribute. Slice thinly against the grain for the most tender bites.

6. Assemble the Caprese topping. On a serving platter, layer slices of steak with fresh mozzarella, tomato halves or slices, and basil leaves. Drizzle with a bit of extra olive oil and a generous swirl of balsamic glaze. Finish with flaky sea salt if you like.

7. Serve and enjoy. This steak is great warm or slightly cooled. Offer extra balsamic glaze and fresh basil at the table.

If you want a sidekick, this grilled caprese flank steak pairs beautifully with roasted asparagus, a crisp green salad, or creamy mashed potatoes.

Cooking Tips & Tricks

• Don’t skip the rest. Flank steak is thin and lean; resting keeps it juicy and forgiving.
• Slice against the grain. This makes each bite tender instead of chewy.
• No balsamic glaze? Reduce 1/2 cup balsamic vinegar with 1 tablespoon brown sugar over low heat until thickened for a DIY version.
• If your family is picky about tomatoes, halve cherry tomatoes and toss them in olive oil and a pinch of salt first — their flavor pops and they’re less watery.
• For an indoor-friendly version, use a hot cast-iron skillet and crank the heat. You’ll still get a great sear.
• Want to switch things up? Try a charred lemon squeeze over the finished dish for a citrus lift.

A Little Kitchen Story

This dish became a favorite in our household after a summer BBQ when Patricia decided to throw together a “fancy” dinner without the fuss. She marinated the steak for 45 minutes, grilled it while I set the table, and we both pretended we had been planning this elegant meal for days. Our kids declared it “restaurant steak,” which, coming from their picky palates, felt like culinary gold.

FAQs

Q: Can I use skirt steak or sirloin instead of flank steak?
A: Yes. Skirt steak is a great substitute and behaves similarly. Top round or sirloin can work, too — just watch cooking times and slice against the grain.

Q: How do I store leftovers?
A: Refrigerate sliced steak in an airtight container for up to 3 days. Reheat gently in a skillet or enjoy cold in salads or sandwiches.

Q: Can I make this ahead for a party?
A: Absolutely. Grill the steak ahead, slice, and reheat briefly before assembling with fresh mozzarella and tomatoes. Keep the basil fresh and add just before serving.

Q: Is this a good balsamic steak recipe for beginners?
A: Definitely. The marinade is forgiving, and the grill time is short, so it’s a great intro to cooking steak.

Q: My balsamic glaze turned out bitter — help!
A: If reduced too quickly on high heat, balsamic can taste burnt. Reduce on low heat, stir often, and remove when it coats the back of a spoon.

Serving Ideas & Variations

• Caprese Salad Plate: Arrange sliced steak over mixed greens with the Caprese toppings for a lighter meal.
• Steak Sandwich: Pile slices into toasted ciabatta with basil, mozzarella, and a drizzle of glaze.
• Kid-Friendly: Serve sliced steak with a side of roasted baby potatoes and a small bowl of cherry tomatoes on the side.

A small swap: use burrata instead of fresh mozzarella when you want to impress — the creamy center is pure luxury and worth the little splurge.
