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, guacamole, and Pico de Gallo!

We love fajitas at our house!  Not only are they delicious and healthy, but they’re also 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 from start to finish!  I used a combination of red and yellow peppers and have also added in a sliced poblano pepper if I have it on hand!

A Healthy Meal

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.

I often top them with low-fat cheese and even Greek yogurt in place of sour cream.  Load them up with crisp lettuce and juicy ripe tomatoes too and fresh jalapenos!

How Do I Season Chicken for Fajitas?

These chicken fajitas are flavored with an easy homemade fajita 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).

Marinade: I add a bit of olive oil and some lime juice to create a chicken fajita marinade. Starting with the chicken, I allow it to sit in the marinade while I prep the rest of the ingredients.

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!

My Favorite Fajita Toppings

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!

  • 3 chicken breasts
  • 1 medium onion
  • 1 lime
  • 3 bell peppers red, yellow, green or orange
  • 3 tablespoons olive oil divided
  • 1 teaspoon chili powder
  • ½ teaspoon smoked paprika
  • ½ teaspoon onion powder
  • ½ teaspoon black pepper
  • ½ teaspoon cumin optional
  • salt to taste


  • Cut onion into slivers & slice peppers.
  • In a separate bowl, combine 1 tablespoon olive oil, juice of ½ lime, chili powder, paprika, onion powder, pepper, cumin and salt. Cut chicken into strips and toss with the spice mixture.
  • Preheat 1 tablespoon olive oil over medium high. Add ½ of the chicken and cook until just cooked, about 3-5 minutes. Remove from pan and set aside. Repeat with remaining chicken.
  • Set chicken aside and add 1 tablespoon oil to the pan. Drain onions well (if soaking per note below) 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.
  • Squeeze additional lime overtop and serve over tortillas.


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.

  1. This is so simple yet so delicious! I used the leftovers for a quesadilla the next day. Quick and easy for a weeknight meal, thanks!5 stars

  2. I’ve made this recipe too many times to count. It’s delicious, healthy, and the leftovers are great fried up. I always double all the seasonings even with 1-1.5lbs of chicken. Sometimes I omit the peppers, sometimes I add a drained can of black beans with the chicken at the end, sometimes I serve it over rice rather than tortillas.. it’s a flexible recipe you can’t go wrong with!!5 stars

  3. I added a small amount of brown sugar to the sauté pan with a little new olive oil to heat my leftovers. The brown sugar took away some of the heat and left it very flaborful. I thoroughly enjoyed eating the leftovers.5 stars

  4. I made two batches of your marinade … one for the chicken and one for the veggies. When I buy prepped fajita mixes both are in the marinade. I think I over did the marinade. I left the two batches in the frig for several hours before I prepared cooked the mix.

    The flavor was excellent, but it was a little too spicey.

    I don’t think you marinaded the veggies which would make a difference.4 stars

  5. This was easy to make. I used 2 large (almost a pound each) chicken breast. Did you use smaller breasts? Next time I will double the spices because you could hardly taste them and I figured it was because I had more chicken. Other than that, we really liked it. I would suggest you add approx how many pounds or ounces of chicken is needed. I’ve used many of your recipes. Thank you.4 stars

    1. Each chicken breast is approximately 6 oz so I use just over a pound of chicken. If you used almost 2 pounds of chicken you would want to increase the amount of seasoning. I hope this helps!

  6. I made this for dinner tonight and it was so delicious. The whole family loved it. I doubled the recipe, which meant I had more batches of chicken to cook, but it was well worth it. It does cook really fast and cooking the peppers separately like the recipe says makes it all PERFECT. This recipe here comes out well seasoned and so delicious. Thank you!5 stars

  7. What I do is pretty much make the same mixture, but I use a flour tortilla, add some of the filling, fold tortilla into a pocket, hold closed with a toothpick and fry it. Makes a fajita pocket. Great with salsa or guacamole.5 stars

  8. Love this recipe and have made it several times. My husband can’t wait until it’s fajita night. I made this with chicken thighs as that was what I had on hand. What would be the approximate weight of 3 chicken breasts. Thanks for this yummy recipe5 stars

    1. We estimate each chicken breast to be approximately 6 oz, so you will want to use just over a pound of chicken breasts. I am so glad to hear this recipe is a hit!

  9. Looks simple – definitely will try it out! One question – I am living a low carb diet, so watching carbs closely. I noticed that the nutrition info has 10g carbs. Although low (and 3g probably from the fiber), I was surprised that it was that much given the ingredients. Do you happen to know if this includes the tortilla? Thanks so much!5 stars

    1. Hi Dean, the nutrition information does not include the tortilla. The carbs in the recipe largely come from the peppers (about half the carbs do). I hope this helps!

  10. Delicious and very easy to prepare. I used the seasoning provided with the recipe but was about to make the homemade seasoning as well. Will definitely prepare it again.5 stars

  11. I haven’t made the recipe yet. I made the seasoning first and then you don’t even use the actual seasoning recipe and I don’t know how much to put in. You really should have put both options in instead of giving different portions of the seasoning with the fajita recipe.

    1. You will need 2 ½ teaspoons of seasoning mix to add to this recipe. You can add a bit more or less to your preference.

  12. I’m confused by your recipe. You mention you season the fajitas with the “homemade fajita seasoning”, which you provide a link for but then the recipe calls for mixing some of the spices contained in the seasoning mix with olive oil and lime. At what point is the homemade fajita seasoning used?

    1. You can use the spices listed in the recipe or fajita seasonings. The seasoning here contains the main ingredients of the fajita seasoning recipe, but is a little simpler. Feel free to use either seasoning recipe. They’ll both be great!
