Why Is Flank Steak The Best Steak for Tacos?
Flank steak is one of the best cuts for tacos because it’s relatively thin and is quite easy to slice. It’s also got a particularly beefy flavor and is good at absorbing marinades due to its grain. For this easy taco recipe we’ll be using my flank steak recipe. I often have extras in the fridge just begging to be used and tacos is a simple idea that my entire family devours.
What You’ll Need
With a ridiculously easy ingredient list, the key to these flank steak tacos lies in the toppings you add to them. Check out the recipe card at the bottom of the post for full ingredient amounts.
- Tortillas – You can use homemade flour tortillas or homemade corn tortillas. Of course store bought works too if you don’t have time for homemade.
- Flank steak – Use my easy flank steak recipe. These tacos are one of our favorite ways to use extras! We will also freeze any leftover grilled flank steak for an easy dinner another night.
How to Make Flank Steak Tacos
With only 3 steps, these might be the easiest tacos you’ve ever made.
- Prepare the tortillas. Heat the tortillas in the microwave wrapped in a damp paper towel, over an open flame, or in a skillet over low heat. Wrap tortillas in foil to keep warm. You can also use a “tortillero” if you have one. A tortillero is a Mexican tortilla basket, here’s a tradtional tortillero and this is a more modern tortillero.
- Cut the steak. Slice flank steak, against the grain, into strips. Make them as thick or as thin as you like.
- Assemble the tacos. Fill each tortilla with sliced flank steak and desired toppings. Serve immediately!
Topping Ideas
These flank steak tacos are great with your favorite combination of the following toppings:
- Homemade Guacamole – Sliced avocado works well too.
- Pico de gallo – Try my favorite fresh Pico de Gallo recipe.
- Mexican crema – Sour cream is a good substitute, just thin it out with a little water to make it more drizzle-able like Mexican crema.
- Salsa – I’ve got a couple of good ones like my Avocado Salsa or Tomatillo Avocado Salsa, but feel free to use your favorite kind.
- Cilantro
- Queso fresco – Cotija cheese is perfect for a bit of sharpness and tang too.
- Lime wedges
- Diced onion – White or red onions both work!
What to Serve With Steak Tacos
Once loaded with toppings, these flank steak tacos are pretty filling on their own. However, you can pair them with a couple of low-carb sides (since the tacos already have tortillas) to complete the meal. For veggie sides, try my Mexican Street Corn Salad (Esquites) and Calabacitas Recipe (Mexican Squash). For more traditional bean-based sides, go for my Frijoles Charros (Charro Beans) or Frijoles Puercos (Mexican Bean Dip). And of course, some Mexican Rice is always a great idea as well.
How to Store & Reheat Leftovers
These flank steak tacos are best served immediately to make sure the steak is super juicy. However, that doesn’t mean you can’t prep ahead. You can refrigerate all the ingredients individually in an airtight container for up to 5 days.
When you’re ready to serve the tacos, sprinkle the steak with 1-2 teaspoons of water and microwave it for up to a minute or until warm. You can also heat it in a pan over medium heat for 4-6 minutes. The tortillas can be reheated as usual, according to the recipe instructions. None of the toppings need to be reheated.
