Balsamic Flank Steak With Grilled Zucchini

The balsamic marinade hit me first that evening at my friend Sarahs backyard dinner the sweet acidic scent cutting through the summer air. I watched her husband tend the grill while she whipped feta in a small food processor something I had never thought to do but immediately understood. The steak came off resting tented under foil while zucchini planks took their turn getting those perfect char marks. When she plated it with that creamy feta base I knew I needed this combination in my life permanently.

I made this for my parents on their anniversary last August. My dad is a steak traditionalist usually skeptical of marinades that might mask the meat but he went back for thirds. The whipped feta was the real revelation though my mom kept asking what I put in it because she could not place the Greek yogurt. They still talk about that dinner.

Ingredients

• Flank steak 1 ½ lbs: This cut is perfect for grilling and marinating slice it against the grain for maximum tenderness
• Balsamic vinegar ¼ cup: The acidity tenderizes while creating a gorgeous caramelized exterior on the grill
• Fresh rosemary 1 tbsp chopped: Woody herbs stand up to the bold balsamic flavor dried works in a pinch
• Feta cheese 6 oz: Block feta gives you better control over the texture than pre-crumbled
• Greek yogurt ¼ cup: This is the secret to making whipped feta actually creamy without adding heavy cream
• Zucchini 3 medium: Look for smaller ones they have fewer seeds and grill more evenly

Instructions

Whisk together balsamic vinegar olive oil minced garlic rosemary Dijon mustard salt and pepper in a shallow dish. Add the flank steak turning to coat completely then refrigerate for at least an hour and up to eight.

Prep the zucchini:

Grill the steak:

This recipe has become my go to for summer entertaining. Something about putting down that platter with the creamy feta and charred vegetables makes people feel taken care of. Last month my neighbor asked if I could teach her how to make it.

Choosing the Right Cut

Flank steak is lean and takes beautifully to marinades but you have to treat it right. Look for a piece with good marbling and uniform thickness. If your butcher has skirt steak that works too though it needs even more attention to slicing direction.

Marinating Magic

The balsamic does double duty here tenderizing and building flavor. I have done this with red wine vinegar in a pinch but balsamic gives that restaurant quality finish. Do not go longer than eight hours or the acid starts breaking down the texture too much.

Grilling Like a Pro

Hot grills and patience create those restaurant quality char marks. Do not flip too early let the protein develop a crust first.

• Clean grates with a brush while the grill is preheating
• Oil the grates right before adding food using a paper towel dipped in oil
• Let the grill do its work constant flipping prevents proper searing

There is something deeply satisfying about a meal that looks impressive but comes together this easily. Enjoy every bite.

Recipe FAQs

→ How long should I marinate the flank steak?

Marinate the flank steak for at least one hour, but up to eight hours yields the most flavorful and tender results. The acid in the balsamic vinegar helps break down the meat fibers while infusing it with tangy depth.

→ What temperature should I cook flank steak to?

Grill the steak over medium-high heat for 4-5 minutes per side to reach medium-rare (130-135°F). Flank steak is best served medium-rare to medium as it can become tough when overcooked due to its lean nature.

→ Can I make the whipped feta ahead of time?

Absolutely. The whipped feta can be prepared up to two days in advance and stored in an airtight container in the refrigerator. Bring it to room temperature before serving for the creamiest texture.

→ What can I substitute for the feta?

For a dairy-free option, try whipped hummus or a dairy-free cheese spread. Goat cheese also works well and creates a similarly tangy, creamy element that complements the balsamic flavors.

→ How do I slice flank steak properly?

Always slice flank steak against the grain (perpendicular to the muscle fibers) into thin strips. This shortens the muscle fibers and ensures each bite remains tender rather than chewy.

→ Can I cook this indoors?

Yes, a grill pan or cast-iron skillet works well for both the steak and zucchini. The skillet will create a nice sear, though you won't get quite the same smoky flavor from charcoal or wood grilling.
