The Very Best Steak Fajitas

Who’s a fan of fajita night!? WE ARE. And even better if fajita night can be prepped and cooked and on the table in under an hour. Hello, easy weeknight meal solution. The whole family will love these steak fajitas, and bonus: we’re sharing a fajita veggies recipe, too.

What are fajitas?

Fajitas are a Tex-Mex dish made with sauteed/grilled peppers and onions and sauteed/grilled meat cut into strips served in a flour or corn tortilla. Popular variations include beef, chicken, and shrimp.

What is the difference between fajitas and tacos?

The main difference between a fajita and a taco is how they are served. Typically, tacos are pre-made, whereas fajitas are assembled at the table.

Veggies + protein = a balanced meal!

Leftovers!

It really only takes 6 basic ingredients to whip up these steak fajitas in your own kitchen:

  • Flank Steak: we prefer a flank steak for these fajitas because it can easily be tenderized very thinly and is oh so tender when cooked. If you can’t find flank steak, skirt steak is a good alternative.
  • Homemade Fajita Seasoning: the key to amazing fajita veggies is making your own fajita seasoning. If you’re in a pinch, you can also buy a packet in stores, but do note that the packet has additives and a thickening agent in it.
  • Bell Peppers: feel free to use any color of bell pepper. We love a good rainbow so we used 3 different colors.
  • Onion: any color onion works. We love the pop of color a red onion adds!
  • Garlic: we’re using whole garlic cloves to really add a flavor blast.
  • Avocado Oil: avocado oil is great for cooking things at a higher heat. It’s also pretty mild in flavor. Feel free to swap for olive oil.

Best Ever Fajita Seasoning

Make a large batch of our homemade fajita seasoning to keep in your spice cupboard.

What spices are in fajita seasoning?

Homemade fajita seasoning is made up of chili powder, cumin, paprika, garlic powder, salt, and pepper.

Best Beef for Steak Fajitas

Flank steak can get a bad rap because it is a more affordable cut of meat (plus, it is quite lean), and can be a bit tough if you don’t cook it correctly.

We love flank steak here on Fit Foodie Finds because when you season and cook flank steak correctly, it’s deliciously flavorful and tender — which makes it a perfect cut of meat for these thinly sliced steak tacos.

Best Tortillas for Fajitas

When it comes to the tortillas, it’s really about personal preference. Are you a corn tortilla person or a flour tortilla person? Regardless, we recommend buying street taco-sized tortillas for the perfect bite every time.

How to Make Steak Fajitas

Tenderize Steak

Place the flank steak on a cutting board and cover it with plastic wrap and pound the steak with a meat tenderizer until the whole piece of meat is about ¾-inch thick. Once tender, season the steak with salt on both sides and massage into the steak.

Slice Fajita Veggies

Thinly slice the bell peppers, purple onion, and garlic into long strips.

Slice Steak

Slice the flank steak into thin strips, using a sharp knife to slice the steak against the grain of the steak. 

Cook Steak

Heat a large skillet with sides over medium/high heat and add the avocado oil to the pan. When the avocado oil is fragrant and hot, add the sliced steak to the pan. Sprinkle 1.5 teaspoons of fajita seasoning over the steak, and cook the steak for 2-3 minutes, tossing the steak occasionally.

Remove the steak from the pan with a slotted spoon (leaving the steak juices and drippings in the pan!) when it still has specks of pink on some pieces.

Sauté Veggies

Add the onion and garlic to the skillet and sauté in the beef drippings and avocado oil. Sauté the onion and garlic for 2 minutes and then add all of the sliced peppers to the skillet and toss with the onion and garlic.

Season the fajita veggies with the remaining 1.5 teaspoons of fajita seasonings. Cover the skillet and sauté the peppers for 5-6 minutes, removing the cover to toss the peppers periodically.

Add steak back

Once the peppers begin to soften, add the steak to the skillet and cook for an additional minute or until the steak reaches the desired doneness. 

Flank Steak Internal Temperature Guide

The best way to tell if your flank steak is cooked is by temperature. Here’s what the internal temperature needs to be:

  • Medium Rare: 130 – 135ºF
  • Medium: 135ºF – 145ºF
  • Well Done: 145ºF – 155ºF

Serve & Enjoy!

Top Tips

Don’t skip the homemade fajita seasoning: Homemade fajita seasoning is the way to go for these fajitas! But if you’re using store-bought, keep in mind that store-bought seasoning tends to be a bit saltier than homemade.

Choosing bell peppers: We use three different colors of bell peppers for these steak fajitas, but you can use any color combination you would like or have on hand.  

A thin flank steak is best: A thin flank steak will yield the best steak fajitas! Make sure you’re both pounding the steak with a meat tenderizer to 3/4 inch thick, and thinly slicing it into strips.

More Ways to Serve Fajitas

Looking to serve these steak fajitas in something other than flour or corn tortillas? Let us recommend any of the following:

Salad: Make a fajita salad! Chop up romaine lettuce and serve your steak fajitas with these fajita veggies, Mexican corn, and our avocado cilantro lime dressing.

Fajita Bowls: Not a tortilla person?! Make a fajita bowl instead. Pair your steak fajitas with cilantro lime rice and serve it with fajita veggies and salsa.

Burritos: chicken burritos and bean burritos are a favorite at FFF, but why not jazz things up with steak? Wrap your sliced steak in a large tortilla and then add Mexican rice, fajita veggies, and refried beans. BONUS – you can easily freeze these for later.

At first these seemed to be a little light on the seasoning, but I added another teaspoon of the fajita seasoning when I added the meat back to the pan, and it was perfect for us! My husband even went back for more and just ate the peppers and meat even after we ran out of tortilla. ๐Ÿ˜‚
