Fajita night just got easier and even more delicious. These Air Fryer Chicken Fajitas deliver tender, seasoned chicken and caramelized peppers with minimal effort. Smoky spices, a squeeze of lime, and fresh cilantro finish the dish for a bright, flavorful meal that’s on the table in under 30 minutes.
Sizzling fajitas are a family favorite, but making them in the air fryer saves time and mess. You won’t need to stand over a hot stovetop or clean greasy splatters. Simply slice the chicken and vegetables, toss with oil and seasoning, and air fry. The method is largely hands-off—just give the mixture a toss every few minutes for even cooking.

- Flavorful and wholesome: seasoned chicken, bell peppers, and red onion caramelize beautifully in the air fryer.

Recipe ingredients
This recipe uses classic fajita ingredients. A homemade taco seasoning keeps the salt lower than many store-bought blends, but any taco or fajita seasoning will work.
- Chicken: Boneless, skinless chicken breast or thighs. Slice into uniform 1/2″ thick strips for even cooking.
- Bell peppers: Any color works; use 2 large or 3 smaller peppers. Poblano can be added for extra flavor.
- Red onion: Halve and slice lengthwise into 1/2″ strips. Leaving part of the root intact when halving helps the slices hold together.
- Seasoning: Taco or fajita seasoning. If using a low-sodium homemade mix, taste and add up to 1/2 teaspoon salt if desired.
- Oil: 2 tablespoons of olive or avocado oil to help the seasoning adhere and encourage browning.
- Finishing: Lime and chopped cilantro to brighten the dish before serving.
