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!

    I cut the steak before cooking it! Can I still pan sear it? I don’t want it to be tough. Thanks!

  2. Barb says:

    Wow, these were so authentic tasting. Due to limited resources of our current crisis, I subbed crushed pineapple for the amount of juice and it was still so delicious. I cooked my veggies in the cast iron skillet on top of the grill and the steak right next to the pan. I even grilled the corn tortillas. Thanks, I will definitely post up next time.

  3. Cassie says:

    Could i cook the steak in a normal non stick calphalon pan? 

    1. Marzia says:

      Yes, that will work, but it just may not develop as nice of a sear because the pan won’t get as hot as cast iron!

    So easy and so delish!  I made these beef fajitas for dinner tonight, and the flavor was incredible.  I think next time I’ll throw some jalapeños in the marinate, as I love spicy, but overall, the dish was magnificent!  Yum ? 

  5. Linda ?? says:

    Wow!  Easy and fun for the whole family.  Loved it so much, we will have it again for supper really soon.

  6. Eric says:

    Quick question. I have read that beef shouldn’t be marinated for more than two hours if your are using lime or lemon juice. The recipe you posted calls for marinating the meat longer than two hours. What am I missing?

    1. Bay says:

      What you’re missing is that skirt steak and flank steak are WAY tougher than other cuts of beef. Trust the recipe. It’s sublime.

  7. Susan K. says:

    Just made these for the first time and they are AWESOME! You can bet they will be in the regular rotation at our house.

    I have never made steak fajitas before – I don’t eat red meat, but my son was begging me to make these for him. I thought the ingredient list looked flavorful so off i went and bought a flank steak (which I have never cooked before) and made this tonite. My 2 sons devoured 2 pounds of meat in less than 10 minutes. This was awesome. We grilled the meat over charcoal – 3/3 min direct 1/1 indirect – perfect medium rare. This is a keeper.

    Excellent! I used Lemon instead of Lime and didn’t have any Cilantro on hand, and it was still wonderful. Will be adding this to my favorites! Thank you for sharing.

    These truly are the BEST fajitas!! Love them! I’ve made them many many times and it’s always my go-to recipe for when company is coming over, I want to impress, have something kid friendly, and easy. Great recipe!

    This has been my favorite fajita marinade for awhile! It’s so delicious and the pineapple juice is simply genius. I recently started Whole30 and had every aspiration to make some homemade worcestershire so we could have these fajitas. Got lazy and decided to use coconut aminos instead. It’s absolutely perfect! Just thought I would share for other Whole30ers out there. 

  12. Elissa says:

    Is there a reason it calls for no sugar added pineapple juice? I cannot find that.  Will it be too sweet if I use regular?

    It was my first time making a fajita. I used tenderloin steak. It was sooooooo good! Husband really enjoyed it! Would definitely make again! Thank you for the recipe!

    Absolutely crazy good
    You’ve just turned a Canadian into a Latino 
    Thanks

    Made this tonight and it was good, should have marinated it longer. My question is that we used a cast iron skillet and there was some smoke but the smoke was almost toxic, burned my throat and made me sneeze and cough (no I don’t cook well or often, I’m sure it was all my fault).

    1. PATRICIA LYNCH says:

      If they were smoking then the heat is way too high, especially indoors.

  16. Judy Johnson says:

    Awesome recipe! My family loved it and we will use it again. The only problem was the steak was tough. Not sure how to make it tender! I’d appreciate any help with that. Next time I’ll use it for the chicken too. Has anyone used this in the crock pot?
    Thanks for your help.

    These truly were the best Fajitas I have ever had.  We did a mix of chicken & beef.  I just finished dinner and sI can’t wait to have them again!  Thank you for sharing this delicious recipe.

    Thank you for taking time to post this recipe. I appreciate you and your effort.
    I tried this recipe tonight. I will not make this again because I keep only the best tasting recipes and this one is just average. Not worth the time and the effort. Some of the store bought fajita rubs are better in my opinion.

  19. Anna Machesky says:

    Definately the BEST fajitas ever!
    My husband and I love them!
    I do a small twist though, I add pinapple chunks and also shrimp.
    The other twist is that I prefer to broil my food, so I put it all (even the peppers and onions) on a sheet pan in the broiler for about 8 min. (Flipping the meat half way through)… and like I said, this recipie is so delish!
