Ingredients You’ll Need

Here’s the best part: most of these ingredients are fresh pantry staples or easy finds at your local market. I’m a stickler for quality here, especially when it comes to the steak and balsamic vinegar, because they really make the dish sing.

• Flank steak (1.5 pounds / 680g) — This cut is great for grilling and slicing thin. Look for a good quality piece with nice marbling. I usually buy from my local butcher or the meat section with good reviews.
• Extra virgin olive oil (3 tablespoons / 45ml) — Use good quality here to marinate and drizzle. It adds richness and helps the steak caramelize.
• Fresh garlic (3 cloves, minced / about 1 tablespoon) — Garlic is essential in the marinade for that punch of flavor.
• Fresh rosemary or thyme (1 tablespoon, chopped) — I like rosemary for its piney aroma, but thyme works well too.
• Salt and black pepper — Generous amounts for seasoning the steak and salad.
• Cherry or grape tomatoes (2 cups / 300g, halved) — Sweet and juicy, these bring brightness to the salad.
• Fresh mozzarella balls (bocconcini) (8 oz / 225g) — I buy the small balls for easy slicing and a creamy texture.
• Fresh basil leaves (1 cup / about 25g) — Tear them up for an herby, aromatic lift.
• Balsamic vinegar (½ cup / 120ml) — For the glaze. Use a good-quality vinegar—aged balsamic works best for sweetness and depth.
• Honey (2 tablespoons / 30ml) — Balances the acidity in the balsamic glaze with natural sweetness.
• Optional: Mixed greens (4 cups / 120g) — If you want to bulk up the salad and add more texture. I like arugula or baby spinach.

Quick note: If you want to switch things up, grilled skirt steak or sirloin can substitute for flank steak, but flank has the best balance of tenderness and flavor for this recipe.

Equipment Needed

You really don’t need fancy gear for this grilled flank steak Caprese salad. Here’s what I use and recommend:

• Grill or grill pan — I use a charcoal grill for that smoky flavor, but a gas grill or even a grill pan on the stove works fine.
• Mixing bowls — For marinating the steak and tossing the salad.
• Small saucepan — To reduce the balsamic vinegar into a luscious glaze.
• Sharp knife — For slicing the flank steak thinly against the grain.
• Cutting board — A sturdy one for carving the steak and prepping veggies.
• Tongs — To flip the steak on the grill easily.

Optional but handy:

• Meat thermometer — Helps you nail the perfect medium-rare without guessing.

How to Make It: Step-by-Step

Alright, let’s get this grilled flank steak Caprese salad going! I’m going to walk you through everything, including my marinade secrets and the magic balsamic glaze.

Step 1: Marinate the Flank Steak (30 minutes)

In a bowl, whisk together 2 tablespoons olive oil, minced garlic, chopped rosemary, salt (about 1 teaspoon), and pepper (½ teaspoon). Place the flank steak in a shallow dish or zip-top bag and pour the marinade over it. Rub it all over and let it sit at room temperature for 30 minutes. This boosts flavor and tenderizes the meat.

Step 2: Make the Balsamic Glaze (10-15 minutes)

While the steak marinates, pour ½ cup balsamic vinegar and 2 tablespoons honey into a small saucepan over medium heat. Bring to a simmer and let it reduce until thick and syrupy—about 10-15 minutes. Stir occasionally to prevent burning. When it coats the back of a spoon, it’s ready. Set aside to cool.

Step 3: Preheat the Grill

Heat your grill or grill pan to medium-high. You want it hot enough to get good sear marks and caramelization on the steak.

Step 4: Grill the Flank Steak (6-8 minutes total)

Place the steak on the grill and cook for about 3-4 minutes per side for medium-rare. If you like it more done, add a minute or two per side. Use tongs to flip just once. For best results, check internal temperature: 130°F (54°C) for medium-rare.

Once done, transfer the steak to a cutting board and let it rest for 5-10 minutes. Resting locks in the juices so every bite is tender and juicy.

Step 5: Prepare the Salad

While the steak rests, halve the cherry tomatoes, drain mozzarella balls, and tear fresh basil leaves. If you’re using mixed greens, toss them lightly in a bowl with a pinch of salt and a drizzle of olive oil.

Step 6: Slice the Steak and Assemble

Slice the flank steak thinly against the grain—that’s key for tenderness. Arrange the steak slices over the mixed greens (if using) or on a large platter. Scatter the tomatoes, mozzarella, and basil over the top.

Step 7: Drizzle and Serve

Drizzle the balsamic glaze generously over the salad. Finish with a final drizzle of extra virgin olive oil and a sprinkle of freshly ground black pepper. Serve immediately.

Total time: About 45 minutes (most of it hands-off).

Expert Tips & Tricks

• Marinate at Room Temperature — I’ve learned that letting the steak marinate and come to room temp before grilling helps it cook evenly and stay tender.
• Don’t Skip the Rest — Giving the steak 5-10 minutes to rest after grilling makes a huge difference. I’ve burned my mouth on hot steak more than once because I was too impatient.
• Thin Slices Make a Difference — Always slice against the grain. It breaks up the muscle fibers and makes the steak easier to chew.
• Make the Balsamic Glaze Ahead — You can make the glaze a day ahead and store it in the fridge. Just warm it slightly before drizzling.
• Use a Meat Thermometer — To nail medium-rare without guesswork.
• Swap Fresh Mozzarella for Burrata — For extra creaminess, try burrata if you can find it. It melts a bit on the warm steak and is heavenly.
• Double the Balsamic Glaze — Because more is almost always better.

Variations & Substitutions

Once you’ve nailed the basic grilled flank steak Caprese salad, here are some ways to switch it up:

• Add Avocado — Creamy avocado slices add richness and pair well with the balsamic.
• Swap Steak for Grilled Chicken — Marinate chicken breasts similarly and grill. I’ve had great results with my creamy chicken recipes, so this salad is a nice fresh change.
• Use Skirt Steak or Sirloin — Both work if flank is unavailable, though flank tends to be more tender when sliced thin.
• Mediterranean Twist — Add kalamata olives and a sprinkle of oregano. I sometimes pair this salad with my slow-cooked beef taco bowls for a fun fusion night.
• Make It Vegetarian — Skip the steak and toss the salad with grilled portobello mushrooms or halloumi cheese for a smoky, hearty touch.
• Gluten-Free — Naturally gluten-free, so perfect for everyone.

Serving & Storage

How to Serve

I love serving this salad right on a big platter so everyone can help themselves. It’s fantastic for casual dinners or backyard parties. Pair it with crusty garlic bread or a simple green salad. Freshly cracked black pepper and extra basil on top never hurt.

If you want to keep things light, a chilled glass of Pinot Grigio or Sauvignon Blanc complements the balsamic and steak beautifully.

Storage

This salad is best enjoyed fresh. The steak and fresh mozzarella don’t hold up well once dressed. If you do have leftovers, store the steak separately in an airtight container in the fridge for up to 3 days. The balsamic glaze can be stored for up to a week.

Reheat steak gently in a skillet or microwave, then add fresh mozzarella and tomatoes before serving again. Avoid storing the salad fully assembled to keep textures fresh.

I’m not a nutritionist, but here’s the scoop if you’re tracking macros: this salad is protein-packed thanks to the flank steak and mozzarella, with moderate carbs coming mostly from the tomatoes and balsamic glaze.

Frequently Asked Questions

Q: Can I use a different cut of steak for this salad?

A: Absolutely! Skirt steak and sirloin are great alternatives if flank isn’t available. Just remember to slice thinly against the grain to keep it tender. Flank steak is my favorite because it has a perfect balance of flavor and texture, but these substitutes work well too.

Q: How do I know when the steak is done?

A: Using a meat thermometer is the easiest way. Aim for 130°F (54°C) for medium-rare. The steak will continue to cook a bit as it rests. If you don’t have a thermometer, cook 3-4 minutes per side on medium-high heat and rest for 5-10 minutes before slicing.

Q: Can I make the balsamic glaze ahead of time?

A: Yes! It actually keeps well in the fridge for up to a week. Just warm it slightly before drizzling if it thickens too much. Making it in advance saves time on busy nights.

Q: What if I don’t have fresh basil?

A: Fresh basil really adds that signature Caprese flavor, but if you’re out, fresh oregano or even a sprinkle of dried Italian seasoning can work in a pinch. Just add it sparingly so it doesn’t overpower the other ingredients.

Q: Can I grill the steak indoors?

A: Yes! If you don’t have an outdoor grill, a grill pan on the stove works well. Preheat it until it’s hot, then cook the steak like you would on a grill. You won’t get the smoky flavor, but you’ll still get great sear marks and caramelization.

Q: How do I reheat leftovers without drying out the steak?

A: Reheat gently in a skillet over low heat with a splash of water or broth to keep it moist. Avoid the microwave if possible, but if you must, do short bursts with a damp paper towel over the steak to trap moisture.

Q: Can I add other vegetables to this salad?

A: Definitely! I sometimes add grilled zucchini, roasted peppers, or even thinly sliced red onions for extra crunch and flavor. Just toss them in with the tomatoes and mozzarella before drizzling the balsamic glaze.
