Air Fryer Chicken Fajitas Ingredients

  • Boneless skinless chicken breast
  • Oil – olive or avocado work great
  • Fajitas seasoning – we used homemade Whole30 Taco Seasoning
  • Veggies – sliced onions and peppers

We used organic chicken breasts from Butcher Box, but you could also use sliced chicken thighs if you prefer.

To make this part of your meal prep, slice chicken and veggies and marinate in the refrigerator for up to 24 hours. We simply keep ours in our favorite mixing bowl covered with a washable silicone lid.

Ready to reheat meals are a key component of our freezer essentials. You can prep and freeze marinated but uncooked chicken breasts in Stasher bags, use a vacumn sealer, or other freezer-safe containers.

I use frozen peppers and frozen onions that I already have on hand, but you can freeze everything together if you prefer.

Pro Tips/Recipe Notes

  • If using storebought fajitas mix, the 1 oz size will make one batch of these fajitas. 
  • Try to cut the chicken to a uniform size to get even cooking results.
  • If you want to prep the onions and peppers to marinate with the chicken, cut them slightly larger than normal to prevent burning during the longer cooking time.
  • To cook frozen chicken fajitas – place the bag in a bowl and defrost in the fridge overnight. Cooking time remains the same.
  • If you double the recipe or your air fryer is smaller, you may need to cook in batches. Place finished fajitas in a clean bowl and cover with a plate or tent with foil to keep warm while the second batch cooks.
  • All air fryers will cook differently. The only way to guarantee your chicken is cooked through is to use a meat thermometer. Chicken is safe to eat when the internal temp is 165 degrees F.
