How to Grill the Juiciest Marinated Flank Steak

You’re three steps away from steak bliss. Here’s a quick description before we dive in: This recipe is all about letting the marinade do the heavy lifting, a hot grill doing the rest, and a bright, fresh chimichurri for that final flavor punch. Follow these easy steps for dinner perfection!

Instructions

Make the Marinade: In a bowl, whisk together olive oil, soy sauce, lime juice, garlic, Worcestershire sauce, sesame oil, oregano, garlic powder, rosemary, salt, and pepper.

Prep the Grill: Heat grill to medium-high (about 450–500°F). Oil the grates for a no-stick situation.
Grill the Steak: Remove steak from marinade, let excess drip off. Grill over direct heat, 3–5 minutes per side for medium-rare (130°F in the center).

Ways to Serve Grilled Marinated Flank Steak with Chimichurri

You’re not limited to “slap it on a plate.” Try these:

Steak Tacos: Warm tortillas, some quick-pickled onions, and a dollop of sour cream.
Steak Bowls: Pile over rice or roasted potatoes with grilled veggies.
Epic Salad: Toss with greens, cherry tomatoes, blue cheese, corn, and your favorite vinaigrette.
Leftover Magic: Sandwiches, wraps, or even scrambled eggs with steak for breakfast (I see you, weekend warriors).

Storage Tips & Meal Prep

Fridge: Store sliced steak in an airtight container for up to 3 days. Chimichurri stays good for a week.
Freezer: Flank steak freezes beautifully! Slice first, wrap tight, and freeze up to 2 months.
Reheat: Gently, please. A quick zap in the microwave with a damp paper towel or a warm skillet—just until heated through.

The Story Behind My Steak Obsession

If you’ve hung around Meat & Melt for more than a hot minute, you know I’m all about comfort food that brings people together. This grilled marinated flank steak with chimichurri was inspired by a family road trip through Texas, where every roadside diner had its own “secret” marinade. I started testing at home, and—after many, many taste-tests—landed on this flavor-packed combo that my whole crew asks for on repeat. It’s easy enough for a weeknight, yet fancy enough for company. That’s what Meat & Melt is all about!

FAQ

How long should I marinate flank steak?

30–60 minutes is plenty! Too long and it can get mushy (thanks, lime juice). If you’re short on time, even 20 minutes will add flavor.

What if I don’t have a grill?

No worries! Use a cast iron skillet or grill pan on the stove. You’ll still get that seared, caramelized crust.

Can I make this ahead for meal prep?

Absolutely! Marinate the steak in the morning, grill in the evening. Leftovers are awesome in salads, tacos, or wraps for lunches.

What’s the best way to store leftovers?

Slice the steak, cool completely, and keep in an airtight container in the fridge for up to 3 days. Freeze for longer storage—just wrap it tight!
