Ingredients for Chimichurri Marinated Flank Steak

Gathering ingredients for this recipe feels like a mini adventure through the farmers market – everything’s fresh, vibrant, and full of flavor. Here’s what you’ll need to make magic happen:

For the Steak:

• 1 lb flank steak – look for good marbling and that signature long grain
• 1/2 teaspoon chili powder – my secret weapon for extra depth
• 1/2 teaspoon each salt & pepper – basic but essential
• 1 lemon or lime – whichever looks juicier at the store

For the Chimichurri Sauce:

• 1 bunch fresh parsley (about 1 1/2-2 cups packed) – stems and all, we’re not fancy here
• 1 cup olive oil – the good stuff you’d drizzle on bread
• 5 cloves garlic – yes, five! (adjust if you’re garlic-shy)
• 1/4 cup red wine vinegar – that tangy backbone
• 1/2-1 teaspoon crushed red pepper flakes – start with less if you’re spice-wary
• 1 tablespoon dried oregano – my grandma’s must-have
• 1/4 teaspoon each salt & pepper – to balance all those bold flavors

Pro tip: If your parsley looks sad, grab two bunches – this sauce deserves the freshest herbs!

How to Make Chimichurri Marinated Flank Steak

Okay, let’s get cooking! This process is simpler than you think, but I’ve got some tricks to make sure your steak turns out perfectly juicy every time.

1. Prep your grill: Crank it up to medium-high heat (about 400°F) while you work on the steak. If you’re stuck indoors, a grill pan works too – just turn on that exhaust fan!
2. Season the steak: Pat your flank steak dry (this helps with browning), then sprinkle both sides evenly with chili powder, salt, and pepper. Don’t be shy!
3. Marinate magic: Here’s where the flavor happens! Coat the steak with about 1/4 cup of chimichurri sauce (we’ll make the rest for serving). Let it soak up those flavors for at least 30 minutes at room temp – or overnight in the fridge for serious depth.
4. Grill time: Toss that beautiful steak on the hot grill. Cook for 6-8 minutes per side for medium-well (less if you like it rare). Resist the urge to poke it constantly – let those grill marks form!
5. Rest is best: Transfer to a cutting board and let it rest for 5-10 minutes. This keeps all those delicious juices inside where they belong.
6. Final touches: Squeeze fresh lemon or lime over the top, then slice against the grain (those diagonal cuts make each bite tender). Pile on extra chimichurri sauce right before serving.

Preparing the Chimichurri Sauce

This vibrant sauce comes together faster than you can say “delicious!” Here’s how I make mine:

Grab your sharpest knife and finely chop the parsley (stems included!) and garlic. Toss them into a bowl with all the other ingredients and whisk like you mean it! The oil and vinegar will emulsify into this gorgeous green sauce that smells like heaven.

Pro tip: The flavors get better as they mingle, so make this first if you can. It keeps beautifully in the fridge for about a week, or freeze small portions for instant flavor boosts later. Just give it a good stir before using – the oil might separate, and that’s totally normal!

Tips for Perfect Chimichurri Marinated Flank Steak

Listen, I’ve made this steak more times than I can count, and here’s what I’ve learned the hard way so you don’t have to!

Marinate like you mean it: That 30-minute minimum? It’s fine, but if you’ve got time, let it soak overnight. The chimichurri works magic as both a flavor booster and tenderizer—trust me, it’s worth the wait.

Fresh herbs or bust: That bottled parsley won’t cut it here. Grab the brightest, crispest bunch you can find—the sauce should taste like a fresh herb garden exploded in your mouth.

Rest that steak! I know it’s tempting to dive right in, but those 5-10 minutes of resting time? They’re the difference between juicy perfection and a dry tragedy. Have patience—slice against the grain when you finally do cut in, and watch those perfect pink strips appear.

Serving Suggestions for Chimichurri Marinated Flank Steak

Oh, the possibilities! This chimichurri marinated flank steak plays so nicely with others. My absolute favorite way? Piled high on a wooden board with grilled asparagus and crusty bread to soak up all those glorious juices. For taco night, slice it thin and wrap in warm tortillas with pickled onions – total game changer! Check out more of our favorite dinner recipes here!

Weeknight dinners love it with garlic rice or roasted potatoes, while fancy gatherings call for grilled peaches on the side (trust me on this one). Leftovers? Toss cold slices into salads or breakfast scrambles – that chimichurri makes everything better!

Storing and Reheating Chimichurri Marinated Flank Steak

Here’s the deal – leftovers rarely happen with this steak (it’s that good!), but when they do, treat them right! Store any remaining steak separately from the chimichurri sauce in airtight containers. They’ll keep happily in the fridge for about 3 days – any longer and the herbs lose their vibrant punch.

When reheating, go low and slow – microwave bursts make the steak tough. I prefer tossing slices in a skillet over medium-low heat just until warmed through. The sauce? Give it a stir and serve cold – that bright flavor shines best at room temp. Pro tip: Freeze extra sauce in ice cube trays for instant steak upgrades later!

Chimichurri Marinated Flank Steak Variations

Listen, rules were made to be broken—especially in my kitchen! The beauty of chimichurri is how easily it adapts to whatever you’ve got on hand. Out of parsley? Cilantro lovers, swap it in for a totally different (but equally delicious) vibe. If red wine vinegar’s missing, squeeze in fresh lime juice—that tangy brightness works wonders! If you prefer a different herb profile, try our garlic herb steak recipe!

Want some heat? Toss in a chopped jalapeño (seeds and all if you’re brave!). Some days I’ll throw in a handful of fresh mint for an unexpected twist. Honestly? As long as you’ve got the garlic, oil, and acid ratio right, you can’t go wrong. Make it yours!

Nutritional Information

Now, I’m no nutritionist, but here’s the deal – this chimichurri marinated flank steak packs plenty of protein while keeping carbs low. That glorious green sauce? Mostly heart-healthy olive oil and fresh herbs, with just enough garlic to keep vampires (and possibly some neighbors) at bay. Exact numbers vary depending on your ingredients (especially that olive oil pour – we’ve all been there!), but it’s a balanced meal that tastes way more indulgent than it actually is. Serve with veggies and you’ve got dinner sorted!

Frequently Asked Questions

Can you marinate flank steak in chimichurri?
Absolutely! That’s actually my favorite way to use it. The acids in the chimichurri work wonders – 30 minutes gives you great flavor, but overnight (up to 24 hours) makes the steak incredibly tender. Just reserve some fresh sauce for serving!

When should I apply chimichurri to the steak?
Here’s my rule: marinate with some, serve with more! Always add that final dollop of fresh chimichurri right before serving – it keeps those herbs bright and vibrant instead of getting cooked out on the grill.

How long does chimichurri sauce last?
In an airtight container in the fridge? About a week. But honestly? Mine never lasts that long – I put it on everything from eggs to roasted veggies! If you need another quick dinner idea, try our Korean ground beef bowl!
