Air Fryer Chicken Fajita Ingredients

Below is a quick overview of what you’ll need. The recipe card further down lists exact amounts and steps.

• Chicken: boneless, skinless chicken breast or thighs, cut into strips.
• Bell Peppers: a mix of colors (red and green shown), sliced into strips.
• Onion: white, red, or sweet onion, sliced.
• Olive Oil: or another neutral oil such as avocado oil.
• Taco or Fajita Seasoning: a 1-ounce packet or about 3 tablespoons homemade seasoning.
• Lime: optional, for squeezing over the finished fajitas.

How to Make Air Fryer Fajitas

You’ll need a mixing bowl and an air fryer. A 4-quart air fryer may require two batches; larger or dual-basket models might handle everything in one go. Follow the steps below for juicy, well-seasoned fajitas.

Slice Chicken and Veggies

Trim and slice the chicken into small, uniform strips. Remove seeds from the peppers and slice them along with the onion into similar-sized strips. Uniform pieces cook evenly and fit better in tortillas.

Season the Chicken and Vegetables

Add the oil and taco or fajita seasoning, then toss the chicken and vegetables until everything is evenly coated. Generous seasoning helps develop a nice crust on the chicken as it cooks.

Air Fry

Preheat the air fryer to 390°F (about 200°C) for 3 minutes. Arrange the seasoned chicken and vegetables in a single layer in the basket—do not overcrowd. For a 4-quart air fryer you may need two batches. Cook for 5 minutes, toss, then cook another 4–5 minutes until the chicken is cooked through and peppers are tender. Finish with a squeeze of fresh lime if desired and serve in warm tortillas.

Serve

Traditionally served in warm tortillas with lime wedges. Popular toppings include sour cream, salsa, guacamole, or a creamy jalapeño dip. Sweet corn salsa or an avocado bacon dip also pair nicely.

Storing and Freezing

Store leftover fajita filling in an airtight container for up to 5 days. Keep the tortillas separate to prevent sogginess.

To freeze, cool completely and transfer the filling to a freezer bag. Frozen fajitas will keep for up to 3 months.

Reheat

Reheat leftovers in 30-second intervals in the microwave until warmed through, or heat in the air fryer at 350°F for about 4 minutes for best texture.

What air fryer should I use?

This method works with both basket and oven-style air fryers. If your air fryer is small, cook in batches. Larger or dual-basket models can likely cook the entire recipe at once.

Tips and Tricks

• Cut meat and vegetables into small, uniform pieces so they cook evenly and fit into tortillas.
• Don’t skip the lime—its acidity brightens the flavors.
• Use oil to help the seasoning adhere and to promote browning on the chicken and vegetables.
