Fall in Love with This Juicy Grilled Flank Steak and Chimichurri Sauce

There's something magical about the combination of a perfectly grilled flank steak and fresh chimichurri sauce that makes my heart skip a beat. As someone who grew up in South America, I can tell you that chimichurri isn't just a sauce – it's a celebration of fresh herbs and vibrant flavors that transforms any cut of meat into something extraordinary.

This recipe brings together two stars: a beautifully seasoned flank steak that cooks in mere minutes and a bright, garlicky chimichurri that packs a flavor punch you won't soon forget. The entire dish comes together in just 35 minutes, making it perfect for both weeknight dinners and weekend gatherings. What I particularly love about this recipe is how it manages to be both elegant and straightforward, impressive yet approachable.

The beauty of this dish lies in its simplicity and nutritional profile – each serving provides 42g of protein while remaining low in carbs, making it a fantastic option for those mindful of their macros without sacrificing flavor. It's a taste of Argentina that brings a touch of South American flair to your dining table.

Tips for the Perfect Flank Steak and Chimichurri

Let me share some game-changing tips that will elevate your flank steak and chimichurri to restaurant-quality levels:

  1. Temperature Matters: Don't skip the 30-minute rest at room temperature before cooking. This step ensures even cooking and a better sear.

  2. The Perfect Cut: Always slice against the grain when serving. This breaks up the muscle fibers and results in tender, easy-to-chew meat.

  3. Chimichurri Secrets: Make the sauce at least 30 minutes before serving to allow the flavors to meld. You can even prepare it a day ahead – it gets better with time!

  4. Oil Quality: Use good quality olive oil for the chimichurri. The sauce is raw, so you'll really taste the oil's flavor.

  5. Herb Freshness: Never substitute dried herbs for fresh in the chimichurri. The sauce's entire character depends on fresh parsley and cilantro.

  6. Heat Control: Keep your grill around 450°F (230°C) – this high heat creates a beautiful crust while keeping the inside juicy.

Serving Your Grilled Flank Steak with Style

This flank steak with chimichurri sauce serves 4 people generously, but trust me – everyone will be craving seconds! For the perfect plate, start with warm crusty bread to soak up any extra chimichurri (it's too good to waste). I like to serve the steak on a wooden board, sliced thinly against the grain, with the vibrant green chimichurri drizzled over top.

For a complete meal, consider pairing it with:

  • Grilled vegetables like zucchini and bell peppers
  • A simple arugula salad with lemon vinaigrette
  • Roasted fingerling potatoes
  • A glass of Malbec for the authentic Argentinian experience

Don't forget to serve extra chimichurri on the side – your guests will thank you!

A Taste of Home: My Chimichurri Story

The first time I made this chimichurri sauce, I was trying to recreate the flavors of my favorite parrilla (steakhouse) in Buenos Aires. I remember standing in my grandmother's kitchen, watching her add ingredients by feel rather than measurement. "Más ajo," (more garlic) she'd say, tasting as she went along. The smell of fresh parsley and cilantro would fill the kitchen, and the sizzle of the steak on the grill would draw everyone outside.

Years later, when I moved to the States, this recipe became my connection to home. Every time I make it, the aroma of the herbs and garlic takes me back to those warm evenings in Argentina. What started as a nostalgic cooking exercise has become my most-requested recipe among friends and family. It's amazing how a simple sauce made with fresh herbs and a perfectly grilled piece of meat can build such strong connections and create lasting memories around the dinner table.

Smart Substitutions for Your Flank Steak and Chimichurri

While this grilled flank steak with chimichurri sauce is perfect as is, I understand that sometimes we need alternatives. Let me share some tested substitutions that won't compromise the essence of this Latin American classic.

For the steak:

  • Skirt steak is the closest substitute for flank steak, offering similar texture and flavor
  • Flat iron steak or hanger steak work wonderfully too
  • Top round can be used, though it's slightly leaner

For the chimichurri sauce:

  • Fresh cilantro can be replaced with extra parsley if you're not a fan
  • Red wine vinegar can be swapped with white wine vinegar or fresh lemon juice
  • Fresh oregano can replace dried (use 2 tablespoons/6 grams fresh instead of 2 teaspoons dried)
  • If you don't have red pepper flakes, use a finely chopped fresh red chili or a dash of cayenne

For olive oil alternatives:

  • Avocado oil works great and has a high smoke point
  • Grapeseed oil is another neutral option
  • Regular vegetable oil will work in a pinch, though you'll miss some flavor complexity

Just remember, the beauty of chimichurri lies in its fresh ingredients. While dried herbs can work in emergencies, they won't deliver the same bright, vibrant flavors that make this sauce so special.

Frequently Asked Questions About Flank Steak and Chimichurri

Can I make the chimichurri sauce ahead of time? Yes! In fact, making it a day ahead allows the flavors to develop better. Store it in the refrigerator and bring to room temperature before serving.

Why is slicing against the grain important? Slicing against the grain breaks up the muscle fibers, making the meat more tender and easier to chew. This is especially important for flank steak.

Can I cook this steak in a pan instead of grilling? Absolutely! Use a cast-iron skillet over high heat, cooking for about the same time as you would on the grill.

How can I tell if my steak is done? For medium-rare, aim for an internal temperature of 135°F (57°C). The meat should feel firm but still have some give when pressed.

Why let the meat rest? Resting allows the juices to redistribute throughout the meat, ensuring every bite is juicy and flavorful.
