Chicken fajitas are an easy and flavorful weeknight meal. A classic Mexican recipe, juicy chicken is seasoned, seared and cooked to perfection, then tossed with sauteed bell peppers and onions. A squeeze of fresh lime adds a punch of flavor and the chicken fajitas are served with warm tortillas and toppings. You can’t beat this healthy family favorite recipe.

Chicken Fajita Ingredients

Don’t you just love meals that only require a few basic ingredients? Well this chicken fajita recipe is just that. All you need is chicken, bell pepper, onion, lime juice and spices, plus tortillas and your favorite toppings. It’s incredibly easy.

It’s a one-pan recipe and in less than 30 minutes, you’ll have a tasty meal (I can’t get enough of those Mexican spices) that also makes for the best leftovers or meal prep.

Homemade Fajita Seasoning is Best

While you can buy pre-made seasoning packets, I’d caution against it. Nothing compares to the flavor of homemade fajita seasoning and it’s easy to whip up. Plus, you’ll avoid any unnecessary fillers and additives. You just need a combination of chili powder, ground cumin, garlic powder, paprika, oregano, salt, and pepper – that’s it!

How To Make Chicken Fajitas

Once you’ve made your fajita seasoning, the chicken fajitas come together fast. Just follow these simple steps:

  1. Season the chicken. Generously sprinkle the fajita seasoning on both sides of the chicken and use your fingers to press it in.
  2. Cook the chicken. Heat a large skillet over medium heat and lightly coat it with a drizzle of olive oil or avocado oil. Sear the chicken breasts for about 7-8 minutes on each side. Then remove them from the pan and let them rest for a few minutes before slicing into strips.
  3. Saute the bell peppers and onion. While the chicken is cooking, cut the bell peppers and onions into thin slices. Then saute them in the same skillet over medium heat for a few minutes until caramelized. You’re essentially making fajita veggies.
  4. Mix together. Add the chicken back into the skillet, squeeze fresh lime juice on top and stir everything together.
  5. Wrap it up. Serve immediately with tortillas and extra toppings.

Do You Need A Cast Iron Skillet?

When it comes to cooking the chicken, a cast iron skillet is ideal for searing. It gives a nice char to it and maximizes the flavors from the seasoning. Just make sure to season your cast iron properly to prevent sticking. But if you don’t own a cast iron pan, you can use a stainless steel pan as well.

Customize Your Chicken Fajitas

While chicken fajitas taste great on their own, toppings can make all the difference. From a dollop of sour cream to cheese or avocado slices, fajitas are a fun way to serve customizable options for your family or a large party! A few of my favorite toppings are pico de gallo and guacamole.

And if you’ve got some chicken fajitas leftover, don’t limit yourself to just wrapping them in tortillas. You can use butter lettuce to make lettuce wraps for a lighter option. Or, you can throw them in a bowl with some leafy greens, black beans, sweet corn and avocado for an easy fajita salad.

Can You Meal Prep Chicken Fajitas?

Absolutely! This is a great recipe to make ahead as the sautéed chicken and vegetables will keep for up to 5 days in the fridge. Just store them in a sealed container and then reheat before adding to a tortilla or salad.

  1. This recipe was…not it. Easy sure, but the fajita seasoning lacked the kick fajitas usually have. I was very excited to find such a simple recipe with such rave reviews but this is not deserving of 5 stars. 2 or 3 is my opinion. Barely any flavor, and not the proper seasoning mix, even when we added way more (proportionally) of each thing. Calling this fajitas is like calling salt & pepper flavorful spices.2 stars

  2. This is my go to for fajitas now and part of my regular rotation. It’s so quick and easy for weeknights! I make it just as described and the seasoning is perfect. I’ll never use a packet for this again. I’ve always cut the chicken into strips first but never again. Who knew?! I’m clearly not a natural cook lol. The sear you get and the juiciness that the chicken retains makes all the difference. I love fresh lime and we add cheddar cheese and sour cream. Yum!5 stars

  3. This is my favourite weeknight meal! I can’t count how many times I’ve made it and it always blows me away. So easy, delicious and healthy!5 stars

  4. I added in some portobello mushrooms as well since they were in the fridge. Used sour cream, your mango salsa (also amazing) and avocado in a tortilla wrap … soooo good!!! Will be using leftovers today in a chicken fajita salad!5 stars

  5. Damn this girl knows her way around a kitchen. I’m in love. If ever I turn up single… I’ll be asking her out. And if she’s married I guess I’ll ask them both out5 stars

  6. It was easy and delicious!! I didn’t change anything! It was perfect. I didn’t have lime, but it 3as still great! Thank you for the recipe5 stars

  7. So good! We ended up cutting the chicken in strips before cooking so the seasoning covers everything. This is such a great option for having guests over!

    1. Hi Rachel – Great way to make the most of the seasoning! I’m glad everyone loved this recipe.

  8. Best Fajita seasoning recipe I have found, hands down!! Followed the whole recipe exactly and they were the best fajitas I’ve ever made!!5 stars

  9. I was trying to think of something good to cook tonight for casual guests. This was perfect. I am allergic to onions and bell peppers, but I subbed those out for carrot shreds and zucchini spears.5 stars

  10. These are SO good! Question, what is a serving size of these? I see the nutrition info and that this makes 6 servings – but no serving size is listed and that would be super helpful for someone like me who is logging food to lose weight.5 stars

  11. Good. However it would be helpful to know the appx wt of the chicken breast you intended for this recipe. I guessed appx 6 to 7 each4 stars

    1. Loved loved this recipe! Thank you so much for sharing this. My family absolutely devoured it. I have tried your humus recipe as well. It’s easy and delicious. Your recipes will be my go to from now on ❤️

    1. I forgot to rate this recipe. 5 stars all the way! After trying this recipe, it’s a good idea for me to buy your cookbook! Thank you once again. 🥰5 stars

  12. Made this for dinner… Only catch was the chicken was frozen… So we sliced it before seasoning and cooking it. Wow was it yummy! This recipe is definitely a keeper.5 stars

  13. I absolutely love this recipe! So easy to follow with great results. Sometimes I will add sliced jalapenos to the peppers and onions if I have them on hand. But the recipe on its own is my go-to. I make it for dinner and always make enough so that there are leftovers for lunches. I originally found this recipe online but liked it so much I bought the cookbook! I was not disappointed. For someone who has a bookshelf full of cookbooks, I keep this one in the kitchen to help with meal plans. Thank you Lisa!5 stars

  14. I love the seasoning mix. If you cook it in advance, what is the best way to reheat it? Covered in a low oven temp? Slow cooker on warm?5 stars

  15. Planning to make this for dinner. Was wondering if the seasoning could be put on the chicken and kept in the fridge ahead of time. The recipe sounds like you season it and fry it right away. Didn’t know if doing it ahead would make the flavor too strong.
    Can’t wait to make it. Thank you!

  16. Tried this recipe for dinner tonight and I must say it was extremely tasty!! What would I change in recipe NOTHING taste just like all our local Mexican restaurants thank you for the recipe!5 stars

  17. This is a family favorite! These fajitas are SO easy to make, yet SO full of flavor and fresh-tasting. We make them so often that I prep a large batch of the rub to have on hand…making the recipe even easier. :) Lisa nailed it, once again….which is why Downshiftology is my absolute “go to” place to find THE best recipes to nourish my family with absolutely delicious, yet simple and healthy whole food.5 stars

  18. This was super easy and hubby liked it. Slicing the veg super thin helped cook it faster and made some caramelization.

      1. I did it! Thank you so much. This was delicious and easy enough. My 1st time was a great success5 stars

  19. The fajitas were a big hit with everyone on New Year’s Eve. I cut my chicken into strips and marinated for a half hour. Other than that, I followed your recipe exactly and used my cast iron fry pan. Very tasty. I tripled the fajita seasoning mix and now have it on hand for the next time!5 stars

    1. I’m glad you enjoyed the chicken fajitas, Becky! And so smart of you to triple the fajita seasoning. It will make it that much easier and faster for future fajitas!

  20. I’ve made this recipe several times and realized I hadn’t left a review. That ends today! My family and I have added this to our regular rotation. It’s a quick, easy, and delicious; a perfect meal for busy weeknights or any night for that matter. Absolutely delicious!5 stars

    1. Thanks so much for taking the time to leave a review, Paula! I’m thrilled you and your family love this recipe. :)

  21. This was absolutely delicious! I skipped the Paprika since I didn’t have any and I marinated the chicken (cut into strips first) in the spice mix + the juice of a lime + some avocado oil for a couple hours. It came out soooo tender and flavorful. I normally don’t repeat recipes within a few weeks but I made this Sunday night and I’m making it tonight (Thursday!) Excellent5 stars

    1. I suggest cooking the veggie portion first, then adding the cooked chicken back into the pan to warm them up! But, it’s best to make this recipe from scratch as you need to season the chicken as well.

  22. I am making this for my family right now. I am a vegetarian so I substituted mushrooms for my portion and seasoned and cooked it separately. It looks amazing already. They are going to love the chicken too.

  23. I just was a tad bit too tired tonight to put it together so I cheated and found this recipe. My goodness so glad I did! Perfect combo of seasoning.
    Thank you,
    GrammyRed5 stars

  24. This recipe is so delicious and easy! It’s my new go to Mexican dish recipe! I’ve made it 5 times at least. And usually my kids eat it well too.5 stars

    1. Wow! I followed your recipe exactly and it’s awesome! I did a combination of shrimp, left over prime rib and chicken breast for the meat. Thank you!
      Renee5 stars

  25. This looks very good,& I am glad you showed us what spices to mix for the fajitas. I didn’t know you could make your own. Thank you for showing me.5 stars

  26. These fajitas are so good! I always make this when chicken is on sale. It’s easy to make and so flavorful. I usually add some crushed red pepper and fresh jalapenos (or canned chiles) because my family likes it spicy :)5 stars
