Mexican food always has a special place in my heart. This is probably due to the fact I’ve lived in San Antonino for four years and in Texas my entire life.

And every time I try out a new restaurant, there is one item I HAVE to order.

The steak fajitas.

You can very quickly determine the authenticity of a restaurant based on this dish. If the beef is no good, chances are the rest of the menu will be subpar as well.

When we moved from San Antonio to Austin, it was difficult to find a restaurant that made them as good.

The solution? Learn how to make steak fajitas at home!

After quite a bit of tweaking and recipe testing, I was able to crack the fajita code. Plus, the steak fajita marinade also doubles to make chicken fajitas, too!

With one simple fajita marinade recipe you can have the best of both worlds.

The key ingredient?… Soy sauce!

It gives the flank steak a lovely umami flavor and the perfect amount of saltiness.

Ingredients

The simple ingredients you need to make these steak fajitas include:

  • Beef. A huge determinant of how tender or tough the fajitas will come out. You can use any cut of meat including flank, skirt, and flat iron. Make sure you get a cut that is no thicker than 1-inch for the best results. See below for more information.
  • Vegetables. The classic bell pepper and onion combo is my go-to. Feel free to add in some mushrooms, zucchini, or squash, too!
  • Taco Seasoning Mix. Homemade taco seasoning is the best and is what was used in this recipe, but store bought will also work if you’re pressed for time.
  • Honey. Pure maple syrup, agave nectar, or even a reduced amount of liquid stevia extract can be used as well.
  • Soy Sauce. This gives the perfect saltiness and umami flavor. Gluten-free soy sauce, or Tamari sauce, have both been tested in this recipe. Substitute for reduced sodium if needed.
  • Worcestershire sauce. Seemingly insignificant, but this gives a TON of flavor! Make sure you look for a gluten-free variety if you are Celiac as some may have hidden wheat.
  • Lime Juice. Definitely the best citrus to use, but lemon or orange juice can also be substituted.

Best Steak for Fajitas

There are a few different types of steak that are best to use when making beef fajitas:

  • Flank Steak – This cut of meat is very lean, which means it is also on the tougher side. It comes from the lower chest and abdominal muscles of the cow. Make sure to slice flank steaks against the grain.
  • Flat Iron Steak– Located in the shoulder of the cow, this is a very tender portion of the cow. It’s incredibly flavorful, due to the higher amounts of fat marbling throughout.
  • Skirt Steak – The toughest of the three, this cut is from the diaphragm muscle and has a fibrous texture. However, this lean cut of meat has incredible flavor. Marinate it well and slice thin for best results.

How to Make

The basic steps for making steak fajitas are simple to follow. Please see the recipe card for exact ingredient amounts.

Fajita Marinade

Whisk together the marinade ingredients in a large bowl. Add steak and let it sit for 1 hour or up to overnight in the refrigerator. The longer it marinates, the more flavorful and tender the beef will be.

Cook the Vegetables

Sauté sliced bell peppers and onions in oil in a cast-iron skillet over medium-high heat until slightly charred. You want them to be tender, yet still crisp. Remove from the skillet and set aside until ready to serve.

Sear the Steak

Cook steak over medium to medium-high heat for 4-5 minutes per side, or until cooked to your desired doneness. Let any excess marinade drip off the steak before adding it to the skillet. Check with a meat thermometer for doneness. A temperature of 130°-135° is medium-rare, 140° is medium.

Slice the Steak

Let steak rest on a cutting board for 5 minutes before slicing. This resting time will help keep all of the delicious juices in.

Cut steak into thin ¼-½” slices against the grain.

FAQs

What is usually in fajitas?

Fajitas generally consist of a meat like chicken, beef, or shrimp, along with peppers and onions. They are often served with tortillas, salsa, sour cream, guacamole, and cheese.

Should you cut steak before making fajitas?

It is not recommended to cut the steak before cooking, as you want them to be medium-rare or medium. Cutting them into smaller pieces before can cause over-cooking. Additionally, pre-slicing will release too many of the juices and result in dry and tough meat.

What is fajita steak called?

The most popular cuts of beef used in steak fajitas are skirt steak, flat iron steak, and flank steak.

Expert Tips and Tricks

  • Cut against the grain. This results in a more tender texture.
  • Make it at home. Homemade taco seasoning is not only healthier, but you can also control the spice level.
  • Marinate for the minimum. Let the steak sit in the marinade for at least an hour for the best flavor.
  • Cast-iron works best. The even and high heat gives the perfect char, and that restaurant sizzle!
  • Let it rest. Allow the cooked steak to sit before slicing to retain the juiciness.
