• Red onion – Yellow or white onions can be used as a substitute.

Step 4: Assemble and serve.

Warm the tortillas, then fill them with the chicken mixture. Top with cheddar and cilantro before serving.

Frequently asked questions

How thick should I slice ingredients?

Slice chicken, peppers, and onion evenly (about ¼–½ inch) so everything cooks through at the same time.

Can I bake the fajitas instead?

You can! Spread everything on a sheet pan and bake at 450 °F for 20 minutes. Keep in mind that they won’t get quite as crispy.

How do I prevent my chicken drying out in the air fryer?

Don’t overcook it! Check that the chicken reaches 165°F and no higher. Thicker slices may stay juicier, too.
