Step-by-Step Directions (simple and friendly)
- Make the marinade: In a medium bowl, whisk together the balsamic vinegar, olive oil, honey, minced garlic, Dijon, salt, and pepper. Taste — it should be balanced sweet and tangy. If it’s too sharp, add a little more honey.
- Marinate the steak: Place the flank steak in a shallow dish or zip-top bag and pour the marinade over it. Massage the marinade into the meat, pressing it flat so the flavors get in. Refrigerate for 30 minutes to 2 hours. If you’re short on time, even 30 minutes makes a difference.
- Prep the grill and toppings: While the steak marinates, slice the tomatoes and mozzarella and arrange the basil. If you like, toss tomato slices with a pinch of salt to bring out their juices.
- Heat the grill: Preheat your grill to medium-high. If using a grill pan on the stove, heat it over medium-high heat and brush with a little oil.
- Grill the steak: Remove the steak from the marinade and let excess drip off (don’t pat it dry — you want some of that flavor). Grill flank steak 4–6 minutes per side for medium-rare, depending on thickness. Flank steak is thin; watch it closely. For well-done, add another minute or two per side.
- Rest and slice: Transfer the steak to a cutting board and tent loosely with foil. Let rest 8–10 minutes — this step keeps the juices in the meat. Slice thinly against the grain for the most tender bites.
- Assemble Caprese-style: Top the sliced steak with mozzarella, tomato slices, and basil. Drizzle with balsamic glaze and a touch of olive oil. Finish with flaky sea salt and red pepper flakes if using.
- Serve: This shines with a simple arugula salad, roasted potatoes, or grilled bread to soak up the juices.
Quick Notes on Temperature and Timing
- Internal temps: Rare ~125°F, medium-rare ~135°F, medium ~145°F. Because flank is lean, I prefer medium-rare to medium for tenderness.
- If using a cast-iron skillet inside, sear steak 3–4 minutes per side and then finish in a 400°F oven for a few minutes as needed.
Cooking Tips (practical, with a wink)
- Don’t over-marinate: Flank steak benefits from acid (balsamic), but too long can break down texture. Two hours max.
- Slice against the grain: This is the biggest trick for tenderness. Look for the long muscle fibers and cut perpendicular to them.
- Mozzarella choice: Fresh is best — it’s creamier and melts slightly onto warm steak. If you have leftover burrata, that’s a dream.
- Balsamic glaze stand-in: If you don’t have a glaze, reduce 1/2 cup balsamic vinegar with 1 tablespoon honey over low heat until syrupy — watch it, it goes fast.
- Feed picky eaters: Serve components buffet-style. Let kids skip the basil or balsamic and still enjoy the steak.
Personal Story from My Kitchen
This recipe became a favorite at my house when Patricia and I were hosting an impromptu dinner for friends. I wanted something that felt special but wouldn’t keep me glued to the stove. The flank steak marinated in the afternoon, and by dinnertime the house smelled like a little Italian trattoria. Our guests loved assembling their own steak-and-Caprese bites, and someone asked if I’d ever considered opening a restaurant. We laughed and agreed — for now, we’ll stick to the blog and the occasional dinner party.
Frequently Asked Questions (FAQs)
Q: Can I substitute flank steak with skirt steak or sirloin?
A: Yes. Skirt steak is similar — slice against the grain. Sirloin is thicker and a little more forgiving with cooking times. Adjust grill time accordingly.
Q: How long can I marinate the steak?
A: 30 minutes to 2 hours is ideal. Any longer and the balsamic can begin to change the texture.
Q: Can I make this ahead of time?
A: You can marinate the steak ahead (up to 2 hours), and slice tomatoes and basil earlier. Assemble just before serving. Leftover steak stores well in the fridge for 3 days.
Q: What’s a good side for this dish?
A: Light sides complement the bold flavors: a simple arugula salad, roasted fingerling potatoes, or garlic bread. For a low-carb option, serve over grilled veggies.
Q: How should I reheat leftovers?
A: Gently warm slices in a skillet over low heat or microwave at 30% power to avoid drying them out. Add a splash of balsamic or olive oil to revive juices.
Q: I don’t have balsamic glaze — any alternatives?
A: A simple balsamic reduction works great (see tips above). A drizzle of aged balsamic or even a light swipe of pesto can be interesting swaps.
Pairing Ideas
- Wine: A medium-bodied red like Sangiovese or a fruity Zinfandel pairs nicely.
- Non-alcoholic: Sparkling water with lemon or a chilled iced tea balances the acidity.
Plating and Presentation (because it matters)
Lay the sliced steak on a long platter, alternate tomato and mozzarella slices, scatter basil like confetti, and finish with a generous drizzle of glaze. Serve with crusty bread so guests can sop up any remaining juices — it’s a visual moment that feels like you spent way more time than you did.
Make-Ahead and Leftovers
If you’re prepping for a gathering, marinade the steak earlier in the day and keep toppings chilled. Assemble at the last minute so the mozzarella stays fresh. Leftovers are excellent in sandwiches, salads, or even chopped into a breakfast hash.
Small Tweaks for Big Differences
- Add charred corn for summer vibes.
- Swap basil for mint or arugula for a peppery twist.
- Toss tomatoes with a touch of shallot and olive oil for a bruschetta feel.
A Few Troubleshooting Tips
- Steak too tough? Likely sliced with the grain or overcooked. Next time, slice against the grain and pull off the grill earlier.
- Sauce too thin? Reduce it over medium heat until it coats the back of a spoon.
- Tomatoes watery? Seed them or use cherry tomatoes to limit extra liquid.
