What Are Fajitas?

Fajitas are a Tex-Mex dish consisting of thin strips of grilled meat served in a sizzling skillet alongside sliced and sautéed bell peppers and onions. Fajitas usually come with a side of flour or corn tortillas and various toppings, so you can “DIY” your own fajita taco. I’m sharing my skillet version here, but you can also try my crock pot steak fajitas and these oven-baked sheet pan steak fajitas.

Steak Fajitas Ingredients 

  • Fajitas Seasoning: I use my homemade fajitas seasoning mix but you can use your favorite store-bought mix.
  • Steak: Lean sirloin or another quick-cooking cut of steak is best (see below).
  • Bell Peppers and Onions: Slice up a combination of green, red, and yellow bell peppers, and yellow onion.
  • Flour Tortillas: You can use regular or whole wheat flour tortillas, slightly warmed up.
  • Toppings: Shredded cheese, sour cream, and guacamole.

What Kind Of Steak Is Used For Fajitas?

The best steak for fajitas is a quick-cooking cut, like sirloin, skirt steak, or flank steak. You’ll slice the steak into thin strips before you start. When cutting the steak for fajitas, it’s important to cut against the grain. This means looking at which direction the lines run in the meat (the “grain”) and slicing across it. Cutting against the grain shortens the muscle fibers, which produces a juicer, more tender steak.

How to Make the Best Steak Fajitas

You’re going to LOVE this easy fajitas recipe, fo’ sizzle. Here’s how to make it:

  1. Sauté the peppers and onions. First, you’ll get the sliced bell peppers and onions sautéing in a cast iron skillet with oil and fajita seasoning.
  2. Add steak. Once the veggies are tender, remove them from the pan and add your steak strips. Stir in additional fajita seasoning and sear until the steak is done to your liking.
  3. Combine. Add the veggies back into the pan with the steak. Let everything heat through for a couple of minutes longer.
  4. Serve! Spoon your steak and veggies over a warm tortilla and top them with cheese, sour cream, and avocado. See further on for more serving ideas.

How To Meal Prep Steak Fajitas

  • To make ahead, simply slice up your peppers, onions, and steak strips the day before, store them in separate bags, and place the bags into the fridge. They’ll be ready to go the following day.
  • Bonus Tip! I love to marinate my steak with the chili lime marinade from my churrasco steak recipe. I just add it to the bag with the steak strips and let it soak. When ready to cook, discard the marinade and cook the steak as directed.

Storing and Reheating Leftovers

  • To store fajitas, place the cooled leftover steak and veggies into airtight containers and refrigerate within 1-2 hours of cooking. They’ll keep in the fridge for up to 4 days or in the freezer for up to 2 months. Defrost the fajitas in the fridge before reheating.
  • To reheat, warm the steak and veggies in a skillet on the stovetop or in the microwave until hot throughout.

    Amazing recipe, and very easy! I cut the meat and veggies earlier in the day, so it was a breeze to out it together! My husband and I both loved it and will definitely make it again!

    1. Katerina says:

      That’s wonderful! Prepping ahead of time is such a great idea. I’m thrilled to hear you both enjoyed it, and I hope it becomes a regular favorite. Thanks for sharing! 🙂

    1. Katerina says:

      That sounds fantastic! Using sirloin and strip steak for a tender, flavorful meal is a great idea. I’m glad you enjoyed it! 🙂

  3. Suzanne says:

    Can I freeze this if so at what stage

    1. Katerina says:

      Yes, you can definitely freeze the fajitas, cooked or uncooked, but you want to freeze only the filling. Freeze the flour tortillas separately.

  4. Ruth says:

    These came out great. I did chicken instead of beef and for the fajitas seasoning I used 1/4 tsp of chili. Will be making again. Thanks so much for sharing.
