Easy Chicken Fajitas

Easy Chicken Fajitas are one of our all time favorite dinners. Tender juicy chicken breasts, fresh crisp peppers and sweet onions tossed in an easy homemade seasoning and piled high in tortillas.

Top these easy fajitas with cheese, sour cream, lettuce and Pico de Gallo!

We love fajitas in our house!  Not only are they delicious and healthy, they’re one of my all time favorite Mexican foods!

These Easy Chicken Fajitas are the perfect weeknight meal because they’re on the table in about 20 minutes start to finish!  I used a combination of red and yellow peppers and also added in a sliced poblano pepper as well as it was what I had on hand!  These are quite forgiving so you can add in whatever you like!

How Do I Season Chicken for Fajitas?

These chicken fajitas are flavored with an easy homemade seasoning.  While you can purchase fajita seasoning packets, I find combining my own spices not only adds more flavor but has less salt and additives.   In a pinch you could use taco seasoning (but add a little bit of extra ground cumin if you have it on hand).

How to Make Chicken Fajitas

This chicken fajita recipe is a total breeze to make!  The chicken is flavorful and juicy while the peppers are perfectly tender crisp! You can have delicious chicken fajitas on the table in just 20 minutes, including prep!

  1. Mix seasoning blend.
  2. Cut veggies and chicken.
  3. Cook chicken in olive oil in a pan, add veggies. (You can make fajitas on the grill if you prefer).
  4. Fill your tortilla shells with your favorite toppings!

Be sure you don’t overcrowd the pan with your chicken or it won’t brown nicely (I do two smaller batches).

I usually soak the onions in cold water while I prep the rest of the ingredients to take a bit of the “bite” out of them for my kids.  This step is optional of course!

We top ours with lettuce, tomatoes, cheese, Homemade Salsa and sour cream…  but you can get creative with the toppings making it a fun family meal!  Olives, shredded veggies such as carrots or cabbage, guacamole or avocados, they all making amazing toppings!

We serve this with a side of  Spanish RiceCrock Pot Corn on the Cob and our favorite Mango Margaritas for a perfect meal!

  1. Cut onion into slivers & slice peppers.
  2. In a separate bowl, combine 1 tablespoon olive oil, juice of 1/2 lime, chili powder, paprika, onion powder, pepper, cumin and salt. Cut chicken into strips and toss with the spice mixture.
  3. Preheat 1 tablespoon olive oil over medium high. Add 1/2 of the chicken and cook until just cooked, about 3-5 minutes. Remove from pan and set aside. Repeat with remaining chicken.
  4. Set chicken aside and add 1 tablespoon oil to the pan. Drain onions well and cook 2 minutes. Add in sliced peppers and cook an additional 2 minutes or just until hot. Add chicken back to the pan and stir to combine.
  5. Squeeze additional lime overtop and serve over tortillas.

Recipe Notes

Optional: If I am serving these to kids, I find soaking the onions in cold water for a bit takes a bit of the "bite" out of them.

Are Fajitas Healthy?

Yes…. as written, these Chicken Fajitas are healthy.  The fajita filling in this recipe is definitely healthy, lean chicken, fresh peppers and homemade seasonings with a dash of olive oil.  I personally love to serve these with corn tortillas since I love the flavor.

These fit perfectly into the 21 Day Fix plan as well if you follow it (just be sure to use corn tortillas and use 1 teaspoon less oil) and they’re perfect if you’re a Weight Watcher!!  21 Day Fix count is 1 red (chicken), 1 green (peppers & onion) and 1 yellow (2 small corn tortillas). This excludes any toppings you may add (cheese, sour cream etc.)

If you’d like to have these as a healthier option, be mindful of your toppings.  Consider using low fat cheese and even use Greek yogurt in place of sour cream.  Load them up with crisp lettuce and juicy ripe tomatoes too!

    1. While I have only made this as written I believe you could make that substitution with success.

  1. Delicious!! I used chicken tenders to save a little time. Bell peppers don’t like me so I used fresh jalapeños instead. Thank you Holly

  2. How can I cook this in the instant pot? Can I just add a little water and cook it all together or should I sauté the chicken first and then add the peppers?

    1. These fajitas take just minutes to cook in the frying pan so I haven’t tried to cook it in the Instant Pot. If you are using an IP, you might just like to add oil and sear in on the SAUTE setting.

  3. I got my husband (grillmaster supreme!) a Camp Chef flat-top grill for xmas and we tried it out for the first time tonight with chicken fajitas. We followed this recipe, using boneless chicken thighs, and it was superb! The spices were right on point. I used a Chipotle Chili Powder, which added even a little more smoke, and also added 2 seeded sliced jalapenos to the peppers, which may have been a little too much for the hubby but worked for me just fine!. Thank you, Holly, it was truly delicious!!!

    1. The spices listed in this recipe make up the fajita sensing mix Michelle. You don’t need a separate fajita seasoning. Hope that helps!

  4. How much did the boneless, skinless chicken breasts in your recipe weigh?  Three chicken breasts is a little vague since chicken breasts come in different sizes. Thanks!

  5. Thank you for a great recipe. The toppings and creative ideas for additions to the basic recipe are so helpful! Any chance the notes section in the recipe print page could include this info to keep it all together? 

  6. This was awesome!! My family loved it and I will be making this again!! We have “taco Tuesday” once every week and this will now be added into our rotation of Mexican dishes!

  7. This was very good & mild. I will put this in my rotation. I did not have lime but used lemon instead & only used a few pinches of smoked paprika. I also added 2 pressed garlic cloves to the chicken.

  8. OMG (Oh! My! Gourmet!) This is the best fajita recipe EVER!!!! It’s definitely going in the “Go-To” recipe box!!

  9. I am planning on trying your easy chicken fajitas recipe. I am currently on the 21 day fix diet. Can you please send me the portion size and container breakdown. Thanks!

  10. So good! I’m wondering if that last tablespoon of oil is necessary (for the veggies) since there’s a lot of liquid in the skillet after cooking the chicken. I may give that a try next time. Thanks for the recipe; will definitely make this again.

      1. This recipe reheats perfectly. I would suggest making the filling and then when you’re ready to eat, just heat the filling portion and prepare your fajitas.

  11. I made this a few weeks ago, and it is by far the best fajita recipe we have tried!!(Beat the heck out of Chili’s and Applebees!) Thank you for sharing. I’m thinking I’m going to try it with some thin sliced pork filet cutlets!! Thank you again!!

  12. This is the BEST recipe for fajitas that I have ever made! So good and the leftovers are great on salad the next day! Just lettuce, the chicken and peppers mix and a little ranch dressing! So good! I have made this so many times and figured I would take a minute to say thanks for sharing! I have posted it so many times on my Facebook as well! :)

  13. Such an easy recipe and I loved it! I tweaked it a little and added more spice with extra chili powder and jalapeños but it was amazing! Thank you so much for sharing !

  14. I make this recipe all the time people would have never guessed that they were weight watchers approved!!so great! Even made a huge batch for a taco bar night and everyone loved them!

    1. I eat this as leftovers and it reheats perfectly. I would suggest making the filling and then when you’re ready to eat, just heat the filling portion and prepare your fajita.

    1. This would be 1 red (chicken), 1 green (peppers & onion) and 1 yellow (2 small corn tortillas). This excludes any toppings you may add (cheese, sour cream etc.)

  15. I added butter and garlic to the olive oil to cook the chicken and topped the fajitas with cilantro, avocado, cheese, and corn! Yum!!!

  16. This was sooooo good! The chicken was very tender. I cooked everything at the same time in different skillets. I topped it off with lime and cilantro and OMG I’m so happy. Thanks kindly…

  17. Hi Holly,
    Was just curious as to why you cook the chicken in two batches instead of just all at one time. I’ve never seen that before in fajita recipe directions. I personally have had to when all I had was a small skillet. -ps-I like your tip about the onion and I’m going to try it. -Thanks!

    1. I just find it cooks better and caramelizes a little better for me if the pan isn’t overcrowded. If you have a large enough pan, by all means do it at once!
      Enjoy Ellen!! :)

    1. This would be 1 red (chicken), 1 green (peppers & onion) and 1 yellow (2 small corn tortillas). This excludes any toppings you may add (cheese, sour cream etc.)

  18. May I ask why the onions soak in cold water? I’ve never heard of doing that before and wondered what the benefit is? I’m always looking for tips!!

    1. I just find it takes a little bit of the bite out, especially since they don’t cook very long. It’s completely optional but my kids prefer them if they’re a little bit milder. :)

  19. Delicious!Made it today and it was so good, everybody enjoyed it :)
    Will be a regular meal at home, thanks for sharing this recipe with us :)

  20. I’m planning on making this recipe for my firehouse tomorrow on shift, should I cut the chicken into strips before adding to the pan?

  21. My family went NUTS over this recipe! I made this for my boy friend’s dinner which we had with my family and everyone raved about how good this was! Comments I received from my family: ” it was the best fajitas they have ever had”. And it’s very easy!
