What Are Chimichurri Steak Tacos?
Originating from Argentina, Chimichurri is a specialty sauce made from fresh parsley, garlic, vinegar, and olive oil, typically used to enhance grilled meats. Its bright, zesty flavor is absolutely irresistible and lends itself beautifully to tacos! When paired with tender grilled flank steak, the taste is a symphony of bold and fresh notes that explode in your mouth.
The unique combination of the rich, meaty steak and the vibrant chimichurri brings a delightful balance to each bite. Imagine the juicy steak nestled in a warm, slightly charred tortilla, topped with creamy avocado, crumbled cotija cheese, and the zing of pickled onions—it’s a flavor experience you simply can’t resist. I recommend making these tacos when you’re craving something more than just a regular taco night. Trust me, your taste buds will thank you!

Ingredients Section
- 1 large red onion, sliced: Adds sweetness and texture; feel free to substitute with white onion if preferred.
- 1/2 cup water: For pickling the onions; you can also use broth for extra flavor.
- 1/4 cup white vinegar: This gives the pickled onions a tangy kick, but apple cider vinegar works just as well.
- 1 tablespoon granulated sugar: Balances out the vinegar for the pickled onions; you can substitute honey or agave nectar here.
- 1 1/2 pounds flank steak: The star of our show! You can also use skirt steak or sirloin for similar results.
- 1 avocado, sliced: Adds creaminess to your tacos; feel free to use guacamole instead.
- Crumbled cotija cheese: This crumbly cheese elevates the taste; feta or queso fresco are great substitutes.
- 2 jalapeños, thinly sliced: For a spicy kick; if you prefer less heat, consider using bell peppers.
- 1 recipe my absolute favorite chimichurri sauce: Trust me, once you try this sauce, you’ll use it in all your meals!
- 8 white corn tortillas (or any taco shell of your choice!): Homemade or store-bought, the choice is yours!
- Cilantro (optional for garnish): Adds a fresh note; you can skip this if you’re not a fan.
Prep Notes:
- Ensure your flank steak is at room temperature before cooking for even cooking.
- For the best flavor, allow the pickled onions to sit longer, even hours if possible.
- Use extra virgin olive oil or avocado oil for the best results, as they have high smoke points for searing the steak.
Step-by-Step Instructions
Pickle the Onions: In a small saucepan, combine the sliced red onions, water, white vinegar, and sugar. Bring the mixture to a boil, then turn off the heat and let it sit for at least 15 minutes. The longer they sit, the more flavorful they become!
Season the Steak: Generously season the flank steak with salt and pepper on both sides. Let it rest while you preheat your cooking surface.
Heat the Pan: Preheat a large cast-iron skillet or grill over high heat. Add a high-heat oil (avocado oil works brilliantly!) to coat the surface of the pan.
Cook the Steak: Carefully place the steak in the pan and cook for 1 to 2 minutes on each side, creating a beautiful char. Don’t forget to sear the edges! Check the internal temperature with a meat thermometer; aim for 135°F for medium-rare, 140°F for medium, or 145°F for medium-well. Remove from heat and let the steak rest for at least 15 minutes.
Char the Tortillas: Preheat your oven to broil. Place the tortillas on a large baking sheet and broil for about 30 seconds on each side, or until they are warm and slightly crisp.
Slice the Steak: After resting, slice the steak into 1/4-inch thick pieces against the grain.
Assemble the Tacos: Lay a tortilla flat and add your desired amount of sliced steak, then top with avocado, crumbled cheese, pickled onions, jalapeño slices, and a generous spoonful of chimichurri sauce.
Serve: Enjoy these delicious tacos with chips, guacamole, and even a refreshing margarita!
Chef’s Tip: For an extra layer of flavor, consider grilling the tortillas over the stovetop instead of the oven for a bit of smokiness.

Expert Tips & Tricks
Storage: Leftover steak can be stored in an airtight container in the fridge for 3-4 days, but I recommend reheating it gently to avoid drying it out.
Make-ahead: Prepping the chimichurri and pickled onions the day before can save you a lot of time. They both develop rich flavors when allowed to sit overnight.
Troubleshooting: If your steak ends up too tough, it may have been overcooked. Use a meat thermometer next time to check the doneness! Remember: always slice against the grain for the best texture.
Reheating: If you have leftover tacos, reheat them gently in a skillet with a little oil to maintain the soft texture of the tortillas.
Serving Suggestions
These Chimichurri Steak Tacos pair excellently with a side of crispy tortilla chips and guacamole, or a fresh garden salad. For presentation, stack them on a colorful platter garnished with fresh cilantro and lime wedges, and bring these beauties to the table for casual gatherings or outdoor parties. They are perfect for taco night or even as the star of a celebratory feast!
Variations & Substitutions
Different Flavor Combinations: Spice things up by adding roasted corn, black beans, or even mango salsa for a tropical twist.
Dietary Restrictions: For a gluten-free option, ensure your tortillas are certified gluten-free. To make it vegetarian, substitute steak with grilled portobello mushrooms or marinated tempeh.
Seasonal Variations: Try adding seasonal vegetables like zucchini or bell peppers, grilled to perfection, during summer. In the fall, consider using squash to add warmth to the flavor profile.
