The absolute BEST Steak Fajitas you’ve ever had! This is my take on the Tex-Mex steak fajitas. Marinated for hours in lime juice, garlic, and cumin — so good you’ll never use another recipe again!

Holy Guacamole!

And I’m not just saying that because steak fajitas NEED guacamole. I’m saying it because you need these homemade fajitas. And I actually can’t believe it took me this long to make them for us. I mean, beef fajitas are a classic, and quite possibly the most delicious thing we’ve eaten around here. Hands down. Like EVER. So it’s totally my food blogging responsibility to bring these to you right now because they couldn’t possibly taste better than they do right now.

These fajitas were gobbled up quicker than anything I’ve ever made before – that’s saying a lot because I feel like I’m ALWAYS cooking. And these make A LOT, enough to feed 4-5 people! We enjoyed them in tortillas the first day and turned them into Chipotle-style fajitas bowls for lunch the next day, and we still had some leftovers! And nope, I’m not even complaining about them. I’ll definitely be making these over and over again on repeat.

You’ve probably made steak fajitas with store-bought fajitas seasoning a million times before. But I’m kind of reinventing this a little because my recipe is less focused on spices and more focused on overall ingredients that marinate, tenderize, and flavor the fajita meat. Because no one likes fajitas that are bland. What’s the point in that?

But this marinade! Oh my Lanta! It is unlike anything you’ve ever tasted before. I was never convinced you could make restaurant-style steak fajitas at home and make them taste better, but this totally does it. They are absolutely are the BEST steak fajitas of your life. The ingredients are simple and straight forward. Also, this isn’t a Harry Potter potions class – you don’t need anything super fancy to make the best fajitas of your life. There is one ingredient in particular that I use that isn’t a typical ingredient one sees in a fajita recipe but give it a try, I promise you, it’s a GAME CHANGER.

I like to use a colorful array of veggies for my fajitas.

You can do with the regular red and green peppers if you’d like, but I love the color and the flavor that yellow and orange peppers add to this recipe. I’m one of those people that eat with my eyes first. I also like to add in a BIG poblano pepper. Remove all the ribs and seeds, so the spice is gone. We just want the nice smokiness of the poblano sizzled with the onions and bell peppers — the flavor is out of this world. I can’t believe I had been making fajitas without poblanos for so long before this. I almost feel like I cheated myself out of the best fajitas.

And the secret ingredient in my steak fajitas is…

Okay, let’s do a quick walkthrough on the ingredients and how you’re going to make the marinade for the fajitas. Without any further suspense let me share with you the ONE ingredient that makes my steak fajitas better than the rest – PINEAPPLE JUICE. Um, yup. You read that right. Pineapple juice, the stuff that comes in a small/large cans in the juice aisle. I use the stuff that is 100% juice with no additional sugars added.

If you’re wondering what the function of pineapple juice is for fajitas, allow me to explain. Store-bought fajita seasonings usually contain enzymes that help tenderize the meat. So to mimic that same tenderization without any weird ingredients, we use pineapple juice. There are people that argue that fresh pineapple juice (that hasn’t been heated) works best. But honestly, for our recipe, canned pineapple juice works just fine! No need to grab a fresh pineapple and make fresh juice, unless you’d like to that is.

What else do you need to make fajitas:

The other ingredients are simple! A little lime juice, some Worcestershire sauce (this is Tex-Mex style fajitas after all!), garlic, chili powder, smoked paprika, cumin, a little olive oil, chopped cilantro, and a little salt and pepper. That is it! No cornstarch or sugar or a million other ingredients. These are simple, flavorful steak fajitas that shine on their own. You don’t need to put a million ingredients in them to taste good.

How to make the best steak fajitas

Now the instructions – combine the ingredients for the marinade and let marinate. It’s that simple. I like to let fajita meat marinate for at least 4 hours and ideally sometimes, overnight. The longer you let them sit, the tastier they are.

I made these indoors on a large cast iron skillet. You can grill the meat out on the grill in the summertime if you’d like. I know we definitely will once it stops raining here EVERY SINGLE DAY and once we purchase a grill. In the meantime, the cast iron skillet is making them just perfectly. ?? I use one large skillet to sear the meat, and while the meat is resting, I add in another tablespoon of oil and allow the veggies to sauté. I love the little bits of the charred marinade to coat the peppers and onions. If you don’t want that, use a separate skillet to make the veggies. Make sure to season them with a hint of salt and pepper.

Be prepared to make this meal on a weekly rotation, served both inside warm homemade flour tortillas and over a bed of cilantro lime rice.

Make it a Sunday tradition, because I have a feeling that this recipe is going to get ten thumbs up.

Ingredients 

Steak Marinade:

  • cup lime juice freshly squeezed
  • ¼ cup pineapple juice no sugar added
  • 2 tablespoons Worcestershire sauce
  • 3 tablespoons olive oil
  • 1 tablespoon minced garlic
  • 2 teaspoons ground cumin
  • 2 teaspoons chili powder or more to taste
  • 1 teaspoon kosher salt
  • 1 teaaspoon smoked paprika
  • ½ teaspoon black pepper
  • ½ teaspoon red pepper flakes or more to taste
  • ¼ cup chopped cilantro

Fajitas:

  • 1 ½ – 2 pounds skirt or flank steak
  • 1 tablespoon oil high heat
  • 2 medium white onions sliced
  • 1 large poblano ribs and seeds removed then sliced
  • 2-3 bell peppers thinly sliced (any color)

Optional:

Instructions 

  • STEAK MARINADE: Combine the ingredients for the marinade in a large shallow bowl or zip-top bag. Give it a taste to check for seasonings and adjust to preference. Coat the steak with the marinade and let sit covered in the refrigerator for at least 2-4 hours and ideally overnight (or see notes to freeze.) Remove from the refrigerator 30 minutes prior to grilling.
  • COOK: Set a large cast iron skillet or grill pan over high heat and let heat up for a couple of minutes. Add the steak to the pan and fry on each side for about 3-5 minutes or longer if you'd like it more done. Feel for desired firmness. The 3 minutes/side will yield a medium rare doneness. If the pan becomes too hot, reduce the heat to medium-high. Remove the steak from the pan and allow it to rest for several minutes, tented with a piece of foil.
  • FAJITA VEGGIES:Add the remaining tablespoon of oil to the pan over high heat, and add in the onions, poblano, and bell peppers. Let the veggies begin to sizzle and toss as necessary, cook for a total of 2-3 minutes or longer if you prefer them softer, season with a pinch of salt and pepper. If your pan is small, cook the veggies in a few batches so they don't steam.
  • SLICE:Slice the meat against the grain into thin slices. I like to do so on an angle so the meat slices are tender and thin. Add it back to the veggies if you'd like.
  • ASSEMBLY: Serve fajitas in corn or flour tortillas or with cilantro lime rice, topped with your favorite toppings!

Notes

  • Freeze: If you aren't planning on making the fajitas right away, marinate the meat in a zip-top bag and freeze immediately. Let the steak defrost in the refrigerator overnight, and you're ready to grill!

    Hands down the best steak fajitas recipe! The pineapple juice was stealthy; nobody knew it was in there but the end result was pure magic. Thank you for this!

  2. Jimmy says:

    I want to add shrimp. Should I marinate it with the steak? What do you recommend?

    This recipe was so good!!! I can’t express it enough. My husband and kids love fajitas and I have never been able to get it right. Flame!!

    Fantastic!!! Tripled the salt amount but kept everything else the same. 

  5. Jim says:

    I know this recipe came out quite a few years ago. So what? OMG, this was just THAT GOOD!

    I did use filet steaks, sliced after cooking. Marinaded for about 4.5 hours. Maybe go longer next time. But, no matter. Just delicious!

  6. NoNameHere says:

    Dumped the marinade in the veggies as they cooked. Turned out well

  7. Nancy says:

    Wow. Excellent combination of the marinade seasonings. Soooo good. 

  8. Natalie says:

    The steak marinade was amazing. Adding that touch of pineapple juice along with the paprika gave it a richer, deeper flavor than most marinades.

    If you’re looking for the very best beef fajita recipe anywhere, just stop right here! I came upon this a couple years ago, (sorry I’m just reviewing now) and it is the only one I use. My only tweak, because I live on a small island where ingredients are hit or miss, is swapping the poblano for a Fresno or even something spicier. Oh, and sometimes I add a dash of liquid smoke, for that, “almost fresh off the grill” flavor. Thank you so much for bringing this delectable bite of love into my life!

  11. Karen says:

    Hi Marzia. This is probably the best and easiest fajita recipe ever. My boyfriend and I enjoy it so much it has become one of our favorite meals when we’re on vacation in the campervan. Thank you!

    These were by far the best fajitas I’ve ever made and probably as good as the best I’ve had in restaurants as well. Perfect recipe, I didn’t change anything. The veggies were perfect, and the flank steak was so tender, juicy and flavorful. We used the grill for ours. No need to ever try another fajita recipe!

  13. Annie says:

    Can I cook the steak in an air fryer

  14. Lisa says:

    Fantastic Recipe – Thank you!!

    Some of the best fajitas I’ve ever had! I used filets instead of flank steak. So tender! Definitely marinade over night if possible. 

  16. Anna says:

    THEE BEST steak fajitas. We adjusted a few things to fit our preferences, but boy this recipe hit the spot. Marinading beforehand I makes the steak especially tender. 10/10 would recommend!

    Made this for the first time tonight. My husband said it was the best fajitas I’ve ever made (married 20 years).  I didn’t have quite all the ingredients, but it still turned out great. Thank you

  18. J. Moore says:

    hmm… I’d be careful marinating in pineapple juice for too long.  Pineapple juice contains the enzyme  bromelain, that can help tenderize meat by breaking down proteins, but prolonged marination can lead to over-tenderizing or even breakdown of the meat.  So 2-4 hours is probably fine, but I’d think twice about marinating overnight.

    This is our new go-to beef fajita recipe!  We cook a lot of Mexican/Tex-Mex and this is one of our favorites.  Wonderful flavor.  Thank you for the recipe!

    I tried this recipe on a whim today and must agree -they are the BEST steak fajitas I’ve ever had.  My husband and I ate way more than we should have!  I only had time to marinate for an hour and the flavor was amazing.
