A Word On Air Fryers
I held out a LONG time before getting an air fryer. As a chef, I just couldn’t see the use of a one-trick appliance like an air fryer. Then, multi-use devices started to come out on the market but I still resisted because my kitchen is small and I don’t have room for counter-top appliances.
Then, my oven went on the fritz. Until I could get it serviced, I bought this Cuisinart multi-use unit with a toaster, oven, broiler, AND air fryer.
I got my oven fixed, but, I’ve hardly used it since getting this neat oven and air fryer combo appliance.
I’m a convert! I love it! I love how quick and versatile it is, and I love that I can make so many things in it without firing up the BBQ or heating up the house with the oven.
BUT not all air fryers are equal. Always consult the manufacturer’s guide for cooking times and temperatures.
My Cuisinart model cooks HOT and 350-F was plenty hot to cook the chicken without drying it out. Adjust your cooking temperatures and times to suit your own air fryer model.
The instructions in this recipe are for a basket-type air fryer. I’m not sure how this would work out in other styles.
How To Make Air Fryer Fajitas
Start by mixing up a batch of this Fiesta Taco Seasoning. This is the fajita seasoning you’ll use to make your fajitas.
Slice two boneless, skinless chicken breasts into fajita-size slices. Toss with a bit of your favorite cooking oil and the Fiesta Taco Seasoning (exact measurements are below in the recipe).
For extra flavor, let the chicken, oil, and spices marinade in the fridge for a few hours ahead of time. But if you’re pressed for time, just move on ahead.
Clean and cut up some veggies. I used two medium-size bell peppers plus 1/2 a red onion.
Cook the chicken first by placing it in a single layer in your air fryer basket. I cooked it on 350-F for about 10 minutes, then flipped it over and added the veggies, and cooked for another 5-8 minutes until the chicken was cooked to 165-F.
What You Need to Make Air Fryer Fajitas

Chef Jenn’s Tips
- You can swap out sliced boneless and skinless chicken thighs instead of breasts.
- Stretch the chicken even further by adding more veggies. Zucchini, asparagus, green beans, or your favorite keto/low-carb veggies can all be added.
- Serve the air fryer chicken fajitas in lettuce wraps to keep it super low-carb, or use your favorite low-carb tortillas.
- For fajita seasoning, I use my Fiesta Taco Seasoning which is probably medium spicy. Add more heat with a pinch more chipotle powder or cayenne.

Are Air Fryer Chicken Fajitas Freezer Friendly?
To freeze, chill them completely in the freezer. Then, package them in an air-tight container, or better yet, use my best friend, a vacuum sealer to get all the air out and really protect your fajitas.
To reheat, thaw thoroughly then heat slowly on a very low heat in your air fryer, or pop them in the microwave.
Peppers will lose some of their texture and become limp when freezing/thawing, but they’ll be just as tasty.
