FLANK STEAK TACOS

Share this BBQ!

I love a good steak, but one of my absolute favorite things to eat are street tacos. I usually order chicken or pork tacos because the steak tacos tend to be a little chewy. That all changes with this flank steak tacos recipe. Every bite is super juicy and tender, and I’m pumped to be able to share this recipe with you.

These are the best flank steak tacos I've ever had. If you're looking for a simple carne asada marinade and a foolproof method to smoke a flank steak, look no further! This is the best way to prepare flank steak.

How to Make Flank Steak Tacos

Another name that you might be more familiar with for these is carne asada tacos. The key to these tacos is a flank steak that is marinated overnight. You can use any flank steak, but I believe the key to really getting these tacos extra tender is to upgrade the quality of your meat.

I used a Snake River Farms Wagyu Flank Steak for these tacos and the extra marbling in that meat made a huge difference.

Carne Asada Marinade

For the marinade you’ll need the following ingredients (full measurement details can be found in the recipe card at the bottom of this post):

  • Lime Juice
  • Garlic
  • Orange Juice
  • Cilantro
  • Salt
  • Black Pepper
  • Vegetable Oil
  • Jalapeno
  • White Vinegar

Combine all of the ingredients in a bowl. Place the flank steak in a large zip lock bag, and then pour the marinade over the flank steak. Place the bag in your refrigerator and let the flank steak marinate overnight.

How to Smoke Flank Steak Tacos

When you are ready to cook the flank steak remove it from the marinade and use paper towels to remove any excess marinade.

Set up your smoker to smoke and place the flank steak directly on your grill grate. Let it smoke for 10 minutes and then adjust the heat on your smoker up to 450 degrees. Let the steak cook until the internal temp hits 130 and then remove from the grill grates. It won’t take long for the steak to come up to temp – 15 minutes tops. Use your ThermoWorks products to spot check temp.

Building the Tacos

Let the flank steak rest for about five minutes and then slice it thin against the grain. Only slice what you’re going to use on the tacos. Leave the rest of the meat intact. This will help the flank steak retain moisture and keep the flavor just in case you have leftovers… Who am I kidding? You won’t have leftovers; but either way, slice the meat as you use it, not all at once.

these are without a doubt the best steak tacos I’ve ever had, and I’m sure they’ll be the best you’ve ever had too.
