How to Make the Best Flank Steak Tacos

Amazing citrus-marinated flanks steak tacos don’t have to be complicated (they can be easy like these Instant Pot Shredded Chicken Tacos). This quick and easy recipe requires just a few everyday ingredients to make flavorful, juicy flanks steak tacos.


The Ingredients

  • Flank Steak. Conquer this tough cut of meat with the power of marinade which tenderizes the meat making it flavorful and juicy (like these Slow Cooker Asian Pulled Pork Tacos). Quality comes into play with the flank steak itself too. You don’t need to break the bank, but beef is an area where you want to buy the best that fits your budget.

TIP!

Don’t forget to give your meat ample time to rest before cutting into it. Also, be sure to cut it against the grain for maximum tenderness.

  • Citrus Juice. A blend of orange juice and lime juice is all you need to make an epically flavorful flank steak taco marinade (or Instant Pot Carnitas) that tenderizes the meat.

Ingredient Note

Since there are so few ingredients in this recipe, be sure to use freshly squeezed orange and lime juice (this citrus press will be your friend). The bottled stuff will throw off the Flank Steak Tacos’ flavor.

  • Garlic. Adds plenty of zip and flavor.
  • Cumin. The ever-essential taco seasoning that adds lovely smoky depth (it’s also key to these Shrimp Tacos with Creamy Taco Slaw).
  • Salt and Pepper. Don’t skimp!
  • Tortillas. Flour or corn, whichever you prefer.
  • Toppings. I like to keep things simple with cilantro, avocado, and queso fresco to let the tender flank steak really shine but you can doctor up yours however you please (maybe with some of the Best Homemade Guacamole).

The Directions

  1. Mix up the marinade and pour it over the steak. Let it do its thing, covered, in the fridge.
  2. When ready to cook, remove the steak from the refrigerator and let stand at room temperature while you prepare any toppings and preheat the grill, oven, or stovetop.
  3. Cook the steak using your chosen method, flipping once.

Tip!

For medium-rare, the steak should read 135 degrees F on an instant-read thermometer.

  1. Remove the steak, cover with foil, and let rest before slicing (across the grain) into thin, 1/4-inch strips.
  2. Warm the tortillas, then assemble the tacos with toppings of your choice. ENJOY!

How to Make Steak Tacos Ahead

  • For ultra-quick flank steak tacos, you can prep the marinade and store it in the refrigerator the night before, pour it over the flank steak before you leave for work, and then come home and the meat will be ready to go.
  • Although you do need to build in time for the marinade portion of the recipe, the good news is once that hour is up, flank steak is freaky fast. The steak cooks in less than 10 minutes.
  • I don’t recommend marinating overnight in this case. I’ve found that anything more than 8 hours tends to break down the flank steak too much.

Frequently Asked Questions

What Can I Do with Leftover Flank Steak?

If you have leftover flank steak tacos (we did), I suggest gently reheating the pieces of steak in a lightly oiled skillet, just until warmed through. You can also cut the leftover steak into smaller pieces, heat it quickly in a skillet, then mix it with warm beans, rice, and your favorite Mexican toppings to create steak burrito bowls.

Is Flank Steak the Same as Skirt Steak?

No. Flank steak, also known as London Broil, is often confused with skirt steak. While these steaks both have a strong beefy flavor and tend to be tougher cuts of meat that require marinating, they are not the same. In fact, they come from entirely different parts of the steer.

Why Do You Cut Flank Steak Against the Grain?

Flank steak tends to be a tough cut of meat (even with an awesome marinade) because of its long, lean muscle fibers. Cutting the meat against the grain shortens these muscle fibers and effectively tenderizes the steak further.

Flank Steak Tacos

5 from 5 votes
Easy flank steak tacos with citrus marinade. This easy recipe for the grill, stovetop, or oven makes the BEST perfectly tender steak tacos.

Prep: 10 mins
Cook: 8 mins
Total: 1 hr 25 mins

Servings: 4 servings

Ingredients
  

For the Flank Steak and Marinade:

  • 1 pound  flank steak trimmed of excess fat
  • 2 tablespoons extra virgin olive oil
  • 2 cloves garlic minced (about 2 teaspoons)
  • 1/4 cup freshly squeezed orange juice
  • 2 tablespoons freshly squeezed lime juice
  • 1/2 tablespoon ground cumin
  • 1/2 teaspoon kosher salt plus additional for grilling the steak
  • 1/4 teaspoon black pepper plus additional for grilling the steak
  • Canola oil for coating the grill

For Serving:

  • 8 7-inch corn or flour tortillas
  • Shredded Monterey jack feta, or queso fresco cheese
  • Other toppings: chopped fresh cilantro diced red onion, sliced or diced tomatoes

Instructions
 

  • Place the flank steak in a baking dish. In a medium mixing bowl or large measuring cup, stir together the olive oil, garlic, orange juice, lime juice, cumin, salt, and pepper. Pour over the steak. Cover tightly with plastic and refrigerate for at least 1 hour or up to 8 hours (do not marinate for more than 8 hours or the steak will break down and soften too much).
  • When ready to grill, remove the steak from the refrigerator and let stand at room temperature while you prepare any toppings and preheat the grill.
  • Preheat an outdoor grill or indoor grill pan over medium-high heat (alternatively, you can cook the steak under your broiler—place your oven rack in the upper third, usually the second closest rack to the top). Brush the grill grates with oil. Remove the steak from the marinade, shaking off any excess. Grill (or broil) the steak for about 3-4 minutes per side, flipping once, until medium-rare (The steak should read 135 degrees F on an instant-read thermometer.) 
  • Remove the steak to a cutting board and cover with foil. Let rest for 5 minutes (this allows the juices to sink into the meat), then cut the steak into thin, 1/4-inch slices, slicing it across the grain.
  • Next, warm the tortillas. Place them in a dry skillet heated over medium-high or heat them on the grill for about 30 seconds per side, until warmed through.
  • To serve, fill the tortillas with a few slices of beef. Sprinkle with cheese and any desired toppings. Enjoy immediately.

  1. I just used that marinade for steak tacos last night and it was a hit! Really flavorful and well seasoned. I added a small amount of steak sauce to the marinade and it was a really nice balance of all the flavors. I also topped them with homemade mango salsa :)5 stars

    1. 48 hours at 135 degrees. I typically use a dry rub for flavor, but if you own a chamber vacuum sealer, you can put the meat in a marinade. I’d use lime juice, some olive oil, lots of salt, plus some cumin and coriander. You could also throw in some smashed garlic.

      1. Chef Mimi, thank you for the tip! I look forward to trying via sous vide. I know it will be awesome! Thank you!

  2. Recipe number … 6 or 7, I’m losing count! This one was surprisingly hard for me, and I suspect a lot of user error. The marinade itself was easy but the cooking tripped me up. It’s freezing here and our grill fell apart this summer, so broiling it was. The problem is that I have very little experience broiling. I followed your rack placement directions but didn’t remember to drain off the extra marinade, so that may have been part of the issue. After ten minutes on one side, the flank steak was still a sort of gray color. I flipped it and did another ten minutes on that side, but the steak was still raw in the middle. Then I moved the rack up and did each side another five minutes each, and it was ready. I let the steak rest but probably not long enough, because lots of juices ran as soon as I started cutting. The flavors were good, but I was expecting something stronger. I marinaded for two hours but maybe that wasn’t long enough? My husband and kids said they enjoyed it, but I think I need to try this one again on a grill. Onward!

    1. Thanks for trying the recipe and sharing your results, Marie! It does sound like the extra marinade didn’t allow the meat to brown properly. I’m happy you still enjoyed it, and I hope it goes even better next time!

  3. These were absolutely amazing! One of my boys worked around the Las Vegas area on a site and after he came home he kept raving about these tacos he had there. I was determined to make him some similar. I found this recipe and BOOM! Instant hit! I used flat iron steak since the other two mentioned were unavailable to me. I, personally, like flat iron better anyway. Per preference of each individual we used either corn or flour tortillas and warmed them in the pan first. This is a keeper and we’ll be making them again!5 stars

  4. Absolutely delicious! I have 2 very picky children, and typically have to make something different for them, but both loved this and even had seconds. I went a little over on the juices, though I did freshly squeeze both. While grilling I poured the remaining juice onto the other side once flipped. I added tzatziki sauce to mine just to change things up a bit!5 stars

    1. I’m so happy that you enjoyed the recipe, Kimberly! Thank you for sharing this kind review!

  5. This looks like a wonderful recipe! Im just wondering where the instructions for the oven baked recipe is? I couldn’t find it!😅

    1. Hi Estefania! Do you mean the for the tortillas? Step 3 gives you all of the details on how to heat them. Hope this helps!

  6. These were SO good and so tender! I marinated for 6-7 hours then grilled, making sure to cut against the grain! Will definitely be making again :)5 stars

  7. Very good marinade! Family loved it! Next time I am going to double the lime juice and garlic just based on preference. Thank you!5 stars
