Ingredients You Will Need
- 2–3 thin-sliced chicken breasts — cooks quickly and stays juicy; slice regular breasts thinly if needed.
- 1 ½ cups frozen mixed peppers and onions — choose a mix of colors for best flavor and appearance.
- 2 tablespoons olive oil — helps seasoning stick and promotes browning.
- 2 tablespoons fajita seasoning — store-bought or homemade both work.
- Salt and pepper — to taste after cooking.

How to Make Air Fryer Chicken Fajitas
Step 1: Preheat the air fryer to 380°F (193°C).
Step 2: In a large bowl, combine the chicken, peppers, and onions. Drizzle with olive oil and sprinkle with fajita seasoning. Toss until everything is evenly coated.
Step 3: Arrange the chicken and vegetables in the air fryer basket in a single, even layer. Cook for 5–6 minutes, shaking or stirring halfway through for even browning.
Step 4: Check the chicken’s internal temperature; it should reach 165°F (74°C). If using frozen vegetables added separately, add 1 ½ cups of frozen mixed peppers and onions on top of the chicken after the initial cook and continue for another 5–6 minutes until veggies are heated and slightly charred.
The vegetables should be tender with lightly browned edges. Toss everything together and serve with warm tortillas, rice, or over a salad.
How to Tell When Chicken Fajitas Are Done
The most reliable test is an internal temperature of 165°F (74°C). Other signs of doneness:
- No pink in the center
- Juices run clear
- Meat is firm but still moist
If needed, return to the air fryer for a few extra minutes until fully cooked.
Easy Homemade Fajita Seasoning (Optional)
If you don’t have a packet, mix common spices for a quick blend:
- Chili powder
- Garlic powder
- Onion powder
- Paprika
- Cumin
- Salt and pepper
This simple combination pairs perfectly with chicken and vegetables; store-bought blends are also convenient.
Best Air Fryer Tips for Chicken Fajitas
- Don’t overcrowd the basket — overcrowding causes steaming instead of crisping.
- Shake or toss halfway through cooking for even results.
- Slice chicken and vegetables evenly so they cook at the same rate.
- Add a touch more oil if the mixture looks dry before cooking.
What to Serve With Air Fryer Chicken Fajitas
- Warm tortillas for classic fajitas
- Rice for a hearty bowl

- Toppings: Greek yogurt or sour cream, pico de gallo, shredded cheese, or guacamole
Garnish with cilantro, lime wedges, or sliced avocado as desired.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the air fryer at 350°F (175°C) for 3–4 minutes or until warmed through to retain texture.
