Ingredient Breakdown & Easy Swaps

What You Need for Grilled Steak Tacos

Flank steak: About 1 pound, sliced against the grain after grilling for that tender, juicy bite.
Salt: For seasoning and bringing out all the beefy flavor.
Oil: Olive oil or avocado oil works great for searing the steak and crisping up those tortillas.
White corn tortillas: Go for the real deal—corn brings way more character than flour here.
Cilantro chimichurri: Homemade or store-bought. If you’re a “herbs are life” person, double the batch.
Pickled red onions: Make your own in 10 minutes or grab them pre-made at the store.
Cotija cheese: Crumbly, salty, and made for taco greatness.
Fresh cilantro: For sprinkling over everything at the end.

Low-carb: Swap tortillas for lettuce cups.
Chimichurri twist: Add parsley or a little jalapeño for a spicy kick.

How to Make Grilled Steak Tacos with Cilantro Chimichurri

Ready to make taco night your best night? Here’s what you’re doing (it’s easier than you think):

Before you start:
Pat the steak dry and salt it up, then let it chill in the fridge for a bit. This simple step makes the meat super flavorful and tender.

Instructions:

Salt & Chill: Sprinkle salt generously over both sides of the steak. Wrap it up and refrigerate for at least 1 hour (or up to a day if you’re a planner).

Prep the Tortillas: Heat a little oil in a skillet over medium. Fry each tortilla for about a minute per side, until golden, puffy, and just a little crisp. Keep them warm under a towel.

Grill or Sear the Steak: Crank up your grill or heat a cast iron pan with a touch of oil. Sear the steak, flipping every couple of minutes, until it’s browned on both sides and hits 130°F in the center for medium-rare (about 8 minutes per side, but keep an eye on it!).

Rest & Slice: Let the steak rest on a board for 5–10 minutes, then slice thinly against the grain for tenderness.

Tips for the Juiciest Steak and Best Tacos

Don’t skip the rest: Letting the steak rest after cooking keeps it juicy.
Slice thin, slice against the grain: This is the trick for steak that’s never chewy.
Warm your tortillas: A quick fry in oil makes them sturdy enough to hold all the toppings and gives those irresistible crispy edges.
Make it your own: Taco night is for experimenting—pile on whatever you love.

Serving Ideas & Leftover Love

Storage & Make-Ahead Tips

Steak: Store leftover sliced steak in an airtight container in the fridge for up to 3 days.
Chimichurri: Lasts a week in the fridge. The flavors just get better!
Tortillas: Best fresh, but you can reheat in a dry skillet to bring them back to life.

FAQ

Can I use another cut of steak?

Absolutely! Skirt steak or flat iron work great. Just watch the cooking time—they’re thin and cook fast.

Slice red onions thin, cover with equal parts vinegar and water, plus a pinch of salt and sugar. Let sit 10–30 minutes.

Can I prep the steak ahead?

Yes! Salt, wrap, and refrigerate up to a day ahead. Grill just before serving for max juiciness.

What’s a good cheese substitute for cotija?

Feta, queso fresco, or even shredded Monterey Jack will work in a pinch.
