Ingredients for Chicken Fajitas

This recipe really is so simple, you will for sure be adding this to your regular dinner menu. To make this recipe you will need some chicken breasts, peppers, onions and just a few spices. This is what you will need to make homemade chicken fajitas:

  • chicken breasts or chicken thighs– either will work in this recipe, make sure they are skinless and boneless. Slice into small strips
  • peppers– red, yellow and orange make for a tasty and colorful fajita
  • onion– a yellow onion is what is used in this recipe, but a red or white onion will work great as well.
  • avocado oil– for cooking everything in, another neutral oil will work also
  • limes
  • small tortilla shells– we prefer flour tortillas for this, but corn would be great too

How to Cook Chicken Fajitas in One Pan

Once you have gathered your ingredients, start by cooking the chicken in some avocado oil in a large skillet over medium high heat. Flip the chicken occasionally to make sure it browns on both sides.

The chicken will cook quickly since it is sliced into smaller pieces. Cook the chicken for 5-6 minutes, until fully cooked through.

Remove the chicken from the pan to a clean plate and then add in the sliced peppers and onion, add more oil if needed.

Cook and stir the onions and peppers over medium high heat until they are soft and browned in some places. This will take another 5-7 minutes for them to fully cook.

Add the chicken back into the pan.

Mix together the spice mix and pour over the chicken and vegetables in the pan.

Stir everything together in the pan until it is all coated in the seasoning. You can add a tablespoon of water to the pan to help the seasonings stick to the chicken and veggies if needed.

Squeeze fresh lime juice over the chicken fajita mixture just before serving for an extra kick of flavor.

Now it’s time to assemble your fajitas. Spoon some of the warm fajita mixture into flour tortillas and top with your favorite toppings. We love to load these up with home with fresh salsa, cilantro, avocados, guacamole and even some sour cream.

Tips for making Homemade Fajitas:

  • Heat the oil in the pan before adding in the chicken so that it will get a nice sear on the outside.
  • Use an instant read thermometer to make sure that the chicken is cooked to the right temperature, this will ensure that your chicken is not too dry or under cooked. The chicken should be cooked to 165º F
  • Don’t over cook the vegetables to the point that they are mushy
  • Serve with warm tortillas
