Pin it Transform your summer grilling with this stunning Mediterranean-inspired plate featuring succulent flank steak steeped in tangy balsamic marinade. The steak achieves perfect char-grilled marks while developing deep caramelized flavors from the vinegar-based marinade. Alongside, tender zucchini planks develop smoky sweetness and gorgeous grill lines, creating a beautiful vegetable component that perfectly complements the rich meat. The crowning element is silky whipped feta, blended until smooth with Greek yogurt and bright lemon juice, adding a cool, creamy contrast to the warm, smoky elements. This impressive yet approachable dinner comes together in just over an hour and serves four generously, making it ideal for summer entertaining or a memorable family dinner.
The first time I made this dish was during a summer rooftop dinner with friends. The balsamic marinade hit the hot grill and created this incredible aroma that had everyone peeking over the railing asking what was cooking. That night taught me that the simplest ingredients—vinegar, garlic, fresh herbs—can transform an ordinary weeknight into something that feels like a restaurant experience. Now it's my go-to when I want to impress without spending hours in the kitchen.
Last summer my neighbor smelled this cooking and actually knocked on my door to ask for the recipe. We ended up eating together on her back porch with way too much wine and these beautiful little plates. There's something about food cooked over fire that brings people together like nothing else. Now whenever I fire up the grill, she somehow appears with her own fork ready.
Ingredients
- Flank steak: This cut takes on marinades beautifully and becomes incredibly tender when you slice it against the grain
- Balsamic vinegar: The acidity tenderizes the meat while creating those gorgeous dark caramelized grill marks
- Fresh rosemary: Woody herbs hold up better to grilling than delicate ones like basil or cilantro
- Zucchini: Slice them lengthwise into planks instead of rounds so they don't fall through the grill grates
- Feta and Greek yogurt: This combination whips into the most luxurious spread that cuts through the rich meat
Instructions
- Marinate the steak:
- Whisk together the balsamic vinegar olive oil garlic rosemary Dijon mustard salt and pepper in a shallow dish. Add the flank steak turning it several times to coat every surface. Let it sit in the refrigerator for at least an hour though overnight is even better for deeper flavor penetration.
- Preheat your grill:
- Get your grill or grill pan nice and hot over medium-high heat. You want it hot enough that you hear a satisfying sizzle when the meat hits the grates. If you're using charcoal wait until the coals are covered with gray ash.
- Prep the zucchini:
- Brush those beautiful long zucchini planks with olive oil and sprinkle them generously with salt and pepper. The oil helps them develop gorgeous char marks while the seasoning enhances their natural sweetness as they cook down.
- Grill the steak:
- Shake off any excess marinade and place the steak on the hot grill. Let it cook undisturbed for 4 to 5 minutes per side for medium-rare or until it reaches your preferred doneness. The balsamic will create a dark flavorful crust that smells absolutely incredible.
- Rest the meat:
- Transfer the steak to a cutting board and tent it loosely with foil. Let it rest for at least 10 minutes so all those delicious juices redistribute throughout the meat. This step is absolutely crucial for a juicy result.
- Grill the zucchini:
- While the steak rests place the zucchini planks on the grill. Cook for just 2 to 3 minutes per side until they're tender with beautiful charred stripes. They should be soft but still hold their shape when you move them.
- Make the whipped feta:
- Combine the crumbled feta Greek yogurt olive oil lemon juice and black pepper in a food processor. Blend until completely smooth and creamy stopping to scrape down the sides as needed. The texture should be like a very light spreadable cheese.
- Assemble and serve:
- Slice the rested steak thinly against the grain into strips. Spread that gorgeous whipped feta across a serving platter then arrange the grilled zucchini and steak on top. Finish with fresh herbs and an extra drizzle of balsamic if you're feeling fancy.
Pin it This recipe has become my signature at summer dinner parties. Something about the combination of smoky charred vegetables and that bright tangy feta just makes people linger at the table longer. I've watched actual arguments break out over who gets the last spoonful of whipped feta. Food that brings that kind of joy is exactly why I love cooking.
Grill Temperature Secrets
Getting the right heat level makes all the difference between perfectly charred and burnt. Medium-high is usually around 375 to 400 degrees which creates those gorgeous sear marks without incinerating the exterior before the inside cooks through. If you're using gas turn one burner to high and leave the others on medium so you have a hot zone and a cooler zone.
Marinating Magic
The acid in balsamic vinegar actually breaks down muscle fibers in the meat making it more tender. But here's what most people don't realize—too much acid for too long can turn the texture mushy and weird. One to eight hours is the sweet spot for this particular marinade. Anything longer and you'll start to compromise that beautiful beefy texture.
Perfect Pairings
A bold red wine with some nice tannins stands up beautifully to the rich steak and tangy feta. Think Syrah Malbec or even a Cabernet Sauvignon. On the side a simple arugula salad with lemon vinaigrette cuts through the richness while roasted potatoes would soak up all those incredible juices.
- Try grilling some crusty bread alongside everything else to sop up the feta
- Cherry tomatoes on the vine grill up beautifully alongside the zucchini
- Leftover steak makes the most incredible tacos the next day

Recipe Q&A
- → How long should I marinate the flank steak?
-
Marinate the flank steak for at least 1 hour, though 8 hours yields the most flavorful and tender results. The balsamic vinegar and olive oil penetrate deeply while garlic and rosemary infuse aromatic notes throughout the meat.
- → What's the best way to achieve medium-rare flank steak?
-
Grill over medium-high heat for 4–5 minutes per side. The high heat creates a beautiful crust while keeping the interior juicy and pink. Always let the meat rest for 10 minutes before slicing to retain those precious juices.
- → Can I make whipped feta ahead of time?
-
Absolutely. Whipped feta can be prepared up to 2 days in advance and stored in an airtight container. Bring it to room temperature before serving for the creamiest texture and most vibrant flavor.
- → What vegetables pair well with this dish?
-
Beyond zucchini, consider grilling eggplant, bell peppers, or red onions. Cherry tomatoes grilled briefly add bursts of sweetness, while asparagus works beautifully during spring months.
- → What wine complements these Mediterranean flavors?
-
A robust red wine like Syrah or Malbec stands up beautifully to the balsamic's acidity and the steak's richness. For white wine lovers, a full-bodied Chardonnay or dry rosé also balances the flavors nicely.
- → How do I slice flank steak properly?
-
Always slice flank steak against the grain, cutting perpendicular to the muscle fibers. This technique ensures tender, bite-sized pieces rather than chewy strips. Look for the direction of the muscle lines running through the meat and cut across them.
