Why You Need Chimichurri Tacos

I used to work at a modern taco place and I've been in love with tacos since. There is so much room to mess with different taco combinations whether it's beef, pork, or Shrimp Tacos with Mango Lime Salsa. But the Chimichurri Steak tacos are so delicious and really quick to make. You can top these with fresh avocado, cilantro, and lime juice to finish them off perfectly and serve them with a side of Cowboy Caviar Salad.

Chimichurri is a traditional Argentinian sauce and it is one of my favorite oil and herb conglomerations. It gives these tacos a burst of flavor that makes my mouth water as I think about it. The combination of parsley, red chile peppers, oil, vinegar, and herbs is almost too much to handle. I love sauces that I can marinate my meat in like chimichurri or Cilantro Mango Vinaigrette!

Ingredient Notes and Substitutions

I separated the ingredients below for the chimichurri and the steak tacos. If you have a chimichurri recipe you prefer, you can substitute.

Chimichurri Ingredients

• Parsley. I use all parsley but you can also add a little bit of fresh cilantro into the mix.
• Jalapeno. Jalapeno is really easy to find but traditionally a red chili pepper is used.
• Lime. I like the flavor of lime, especially with steak. Lemon is traditionally used in chimichurri though and can definitely be substituted.
• Shallot and Garlic. I use both. I like the subtle flavor of shallot and just a little bit of garlic flavor. The longer the garlic sits in the sauce the more potent it becomes. I prefer a small amount of garlic and a shallot for this reason.

Steak Tacos Ingredients

Red Onion. Raw red onion is perfectly fine. But you can also use pickled red onion if you prefer.

Tortillas. I like to get the little tortillas. Sometimes they will be labeled as fajita tortillas. I always go with flour tortillas for these tacos. Chimichurri is an oily sauce and it always rips right through corn tortillas. I'm sure most people prefer corn because it is more traditional. Either will work though.

How to Make Chimichurri Sauce

Step 1: Coarsely chop parsley until it is evenly cut.

Step 2: Add parsley, to a bowl with chopped shallot, jalapeno, and minced garlic.

Step 3: Add olive oil, lime, crushed red pepper, and oregano to the mixture.

Step 4: Whisk the mixture together until combined and set aside.

Cast Iron Steak Directions

Step 5: Marinate the steak for 1-12 hours. Add ½ cup of chimichurri sauce to a bowl and toss the steak in it. Cover and refrigerate.

Step 6: Remove your steak from the fridge 30-60 minutes before cooking. Heat your cast iron to medium-high heat. Then drizzle with avocado oil. Once hot, place the steak on the pan and cook for approximately 5 minutes until the steak develops a crust.

Step 7: Flip the steak and cook for another 5 minutes or until the steak reaches 130° F, for a medium rare steak.

Step 8: Pull the steak off of the cast iron and allow it to rest for ten minutes. This is really important. Cut into the steak right away and you'll lose all of the juice. Slice the steak against the grain so that it is easy to chew.

Assemble the Tacos

Place a pan in the oven and preheat to 350° F. Pull the preheated pan out of the oven and place your tortillas on the pan. Add the pepper jack cheese and return to the oven until they are melted (about 3 minutes.

Toss the steak with the remaining chimichurri sauce. Then add the steak to the tacos. Top with red onion, avocado, cilantro, and lime juice. You can also substitute an Avocado Lime Crema for the avocado!

Chimichurri steak tacos are a fantastic option for a quick and easy weeknight dinner, and they're also a great way to mix up your usual steak meal. The tangy, herbaceous flavors of the chimichurri sauce combine perfectly with the seared flank steak. The soft flour tortillas provide the perfect base for all those bold flavors to shine.

Serve them with a side of Fried Green Tomatoes or a big Easy Chipotle BBQ Chicken Salad with Chipotle BBQ Sauce and Cilantro Lime Ranch Dressing!

Pro-Tips

1. Allow the steak to cook for at least 5 minutes without even touching it. The more you pick it up the more steam will be created. Get the best sear by letting it sit undisturbed. 
2. Always slice the steak against the grain, especially for tacos and sandwiches. This will make it a lot easier to bite into so it doesn't feel like you have to tear the steak with your teeth. 

Recipe FAQs

What goes well with Chimichurri steak?

I love to top it with pickled red onions or avocado. An avocado lime crema is a great addition to steak tacos! Serving it on tacos is my absolute favorite but you can also serve it with a side of roasted potatoes, over mashed potatoes, with roasted vegetables, or on a sandwich!

Is Chimichurri Mexican?

While Mexico has some of the best foods, they cannot claim chimichurri. It is an Argentinian creation made with parsley, olive oil, garlic, onion, red wine vinegar, and spices.
