Medium rare flank steak sliced into strips topped with fresh chimichurri sauce

This chimichurri flank steak is crazy flavorful, thanks to a perfect chimichurri sauce. Cooked medium rare inside on the skillet, the flank steak is super tender, and it’s all easy and quick to throw together, coming together in about 30 minutes, not counting marinade time. Great for entertaining and good on the grill, too! Whole30, clean eating, paleo, low carb, and keto.

Show of hands: who loves chimichurri flank steak (or churrasco) as much as I do?

Wrong – trick question! Literally, no one loves chimichurri flank steak like your girl. Impossible! My mouth waters at the thought of hitting the local churrascaría for dinner. Oh, and there’s not even a question from my husband when a special occasion is coming up. He already knows where we’re going to dinner.

Where, you ask? Where the chimichurri flows freely, and the flank steak is super tender and coated in the stuff. Bonus points for Brazilian cheesy bread (pão de queijo, if you want to be fancy) and caipirinhas!

What Makes This Recipe So Good

The reason I love chimichurri flank steak so much is simple: it’s heavy on the flavor, but it’s surprisingly easy to make at home. While it does taste best when it’s been marinated, it takes only a few minutes to sear in a cast-iron skillet. And yes, you read that right! No need to bundle up in the winter or sweat your buns off in the summer to grill this chimichurri flank steak. I like it best seared in a super hot, heavy skillet: done quickly with a gorgeous crust. Perfection.

Oh, and that chimichurri sauce? I adapted the recipe from Texas de Brazil’s years ago, and it’s a favorite recipe on my site. It’s the ideal blend of parsley and cilantro, plus fresh garlic, dried oregano, spicy chili flakes, fresh lemon juice, and rich olive oil. We have a jar in the fridge at all times and have for the last six or seven years. Yes… it’s that good.

Why You’ll Love It

  • The chimichurri sauce is absolutely bursting with flavor and comes together super quickly in the blender or food processor.
  • Using flank steak makes this recipe affordable and easy. It’s a good cut of meat but not too expensive, like a nice ribeye or strip. However, it’s still super tender and doesn’t require a lot of work to make delicious!
  • Marinating the flank steak in the chimichurri sauce tenderizes the meat and injects it with tons of flavor.
  • The chimichurri sauce is my favorite, hands down. It’s the perfect blend of bright lemon juice, lots of fresh garlic, herbaceous parsley and cilantro, dried herbs, a bit of spiciness, and a salty touch.

Chef’s Tips

  • Make sure you cut the steak against the grain. To do that, look for little grooves or lines in the meat. They should all generally go one way. You will want to cut perpendicular to this grain or flow. So say the grain runs east to west from your vantage point, cut north to south (or south to north – same deal!) to cut against the grain. This makes a big, big difference in the tenderness of your chimichurri flank steak, believe it or not.
  • You can swap out other cuts of meat for the flank steak here, like skirt steak. Marinate the steak as you would in this recipe but increase or decrease your searing time, depending on how thin or thick the steak is.
  • Make the chimichurri sauce in the food processor: blitz the garlic first, followed by the herbs. Add in the remaining ingredients and blend until the desired texture. So quick and easy!

Can I Grill This Steak Instead?

Go for it! This recipe will give you some good guidance when it comes to actually grilling the flank steak. You’ll follow the directions of this recipe the same in terms of making the chimichurri sauce and marinading the steak. However, just follow their process when grilling!

TL;DR version: Heat the grill to 450º F. Grill 4-5 minutes per side or until your internal thermometer reaches 130-135 degrees. After that, carry on with the recipe as written here!

Ingredients

  • 1 ½ – 2 pounds flank steak

For the Chimichurri Sauce

  • 2 tablespoons fresh garlic peeled
  • ½ cup fresh parsley
  • ¼ cup fresh cilantro
  • 1 cup olive oil or avocado oil
  • ¼ cup fresh lemon juice
  • 1 tablespoon dried oregano
  • 1 tablespoon crushed red pepper
  • ½ tablespoon salt plus more to taste

Instructions 

For the Chimichurri Sauce

  • In a food processor, add the garlic. Pulse until minced. Add fresh parsley and cilantro and pulse until finely chopped. Add remaining chimichurri sauce ingredients and pulse until well combined. Set aside.

For the Steak

  • Marinate the steak: If the steak is large, about 2 pounds, or too big to fit into your skillet, cut it down the middle now. Make sure to cut against the grain (See Tips section in post content for help). Place steaks in a large baking dish or plastic food storage bag and add ⅓ cup chimichurri. Turn to coat. Marinate for at least 30 minutes, preferably 1-2 hours.
  • Sear the steaks: Heat a large cast iron skillet over medium-high heat for about 3 minutes. Remove steaks from chimichurri and scrape off excess marinade. Pat dry and sprinkle with a modest amount of salt.
  • If working with two pieces of steak, pour 1 tablespoon of avocado oil into a cast-iron skillet and let heat about 30 seconds or until shimmering but not smoking. If working with steak in one piece, pour 2 tablespoons avocado oil in and heat.
  • When the oil is shimmering, use a pair of long tongs and carefully place steaks in skillet. Cook 3-4 minutes on each side, depending on the thickness of the steak. See Notes for details.
  • Remove steak from skillet and let rest on a cutting board for 5 minutes. Repeat with the second piece of steak, if steak had been cut in two. After resting, cut the steak into ½" slices against the grain. Arrange on a large serving platter and top with fresh chimichurri sauce. Serve with additional chimichurri.

Notes

Cook Times (Approximate)
  • For a thicker piece of flank steak:
    • 3 minutes per side = medium-rare
    • 4 minutes per side = medium
  • For a thinner piece of flank steak:
    • About 2 1/2 minutes per side = medium-rare
    • 3 minutes per side = medium
 
Meat Thermometer Test for Doneness
  • Medium rare = 130–140°F (55–60°C)
  • Medium = 140–150°F (60–65°C)
  • Medium well = 150–160°F (66–69°C)
  • Well done = 160–170°F (70–75°C)
 
Touch Test for Steak Doneness
If you don’t have a meat thermometer, use your tongs to test for doneness. Gently poke the center of the steak whilst searing with a pair of blunt tongs pressed together.
  • Rare will feel very soft.
  • Medium rare will feel a bit firmer but still tender.
  • Well-done will feel very firm.

    My chimichuri comes out too thin. Should I reduce the olive oil? How do I measure the parsley and cilantro. Should I give it a rough chop first and then measure

      No need to chop the fresh herbs first – the food processor will take care of that. Just make sure to fill the measuring cup to the brim. Don’t be afraid of overdoing the herbs, either!

    The first time it turned out perfect, yummy best flank ever! Second time too salty – but then I realized that the recipe did not call for sea salt…is that possibly why it is too salty for some? I only used a teaspoon and it was way too salty.
    But I will say, that have gotten used to putting in a half of a medium poblano pepper to the sauce and it gives it an even more amazing flavor. I cut back on the red flakes by half when I do this.
    If you are using grass fed steak – let it marinade over night. You will never throw it in a crock pot again…5 stars

      Great tips! And yes, sea salt is a lot saltier than table salt. That could have easily been the issue. Regardless, glad you have enjoyed this recipe!5 stars

    This is my go to chimichurri recipe. It has WAY too much salt and way too much oil. I also lower the amount of red pepper flakes used by about half. Thats a preference.. The salt I use a half tsp and then the rest to taste. 1/2 tbsp salt sounds like a heart attack and I’ve tried it, its unbearable. Its perfect at about 1/4cup of lemon juice to 1/2 cup oil. If you follow the recipe it just becomes an oily, salty and sloppy mess that you can’t stir out.4 stars

        A few tweaks and this is such a good recipe, it really all depends on preference though. I’ve tried it with all of the red pepper flakes as well as with cilantro only, and I have also accidentally used lime juice instead of lemon. Still good either way. I’ve put it on steak, veggies, and about to try it on chicken… It definitely depends on what kind of salt you use as well. I follow the recipe except the oil and salt, I just add both until it balances out. Use it all the time and I put it on everything, thank you for sharing!5 stars

        Thank you so much, Ciana! You’re totally right, it’s a great recipe to adjust to preference, and there are a lot of ways to mix it up! This version is an exact copycat of Texas De Brazil’s chimichurri, but there are so many other ways to make the sauce and they’re all delicious. I’m so glad you enjoy it so much!

      It was overkill with a cup of oil. This is my first time making this and I just kept adding parsley and cilantro to thicken it up. I like things spicy but I wish I had read your comment before adding 1 tablespoon of red pepper flakes, as my boyfriend’s palate is more sensitive to heat than mine. Great color and I mixed lime/lemon juice.4 stars

    Is the sauce good on tuna steaks or other meats? And, if some is leftover, how long will it last in refrigerator?

      Leftovers will keep roughly 2 weeks as long as you refrigerate it in an airtight container. And yes, the chimichurri is good on a variety of proteins! We have a recipe for chimichurri shrimp you might like: https://40aprons.com/chimichurri-shrimp-skewers-whole30-keto/
