Ingredients
  

  • Chicken: 1.5 pounds boneless, skinless chicken breasts or thighs, thinly sliced
  • Bell peppers: 3 medium (mix of red, yellow, and green), thinly sliced
  • Onion: 1 large yellow or red onion, thinly sliced
  • Olive oil: 2 tablespoons
  • Lime: 1 lime (zest and juice)
  • Garlic: 2 cloves, minced (or 1 teaspoon garlic powder)
  • Chili powder: 2 teaspoons
  • Cumin: 1.5 teaspoons
  • Paprika: 1 teaspoon (smoked paprika if you like a smoky flavor)
  • Oregano: 1/2 teaspoon
  • Salt: 1 teaspoon, plus more to taste
  • Black pepper: 1/2 teaspoon
  • Optional heat: 1/4–1/2 teaspoon cayenne or red pepper flakes
  • Tortillas: Warm flour or corn tortillas, for serving
  • Toppings: Fresh cilantro, avocado or guacamole, salsa or pico de gallo, sour cream or Greek yogurt, shredded cheese

Method
 

  1. Prep the chicken and veggies: Slice the chicken into thin strips about 1/2 inch wide. Thinly slice the peppers and onion so everything cooks at the same speed.
  2. Mix the seasoning: In a large bowl, combine olive oil, lime zest and juice, garlic, chili powder, cumin, paprika, oregano, salt, black pepper, and cayenne if using. Stir into a paste.
  3. Toss to coat: Add the chicken, peppers, and onion to the bowl. Toss until everything is evenly coated. Let it sit for 10 minutes while you heat the air fryer.
  4. Preheat the air fryer: Set to 390–400°F (200–205°C) for 3–5 minutes. A hot basket helps get better sear and caramelization.
  5. Arrange in the basket: Spread the mixture in an even layer. Avoid piling it too high. Cook in batches if needed to prevent overcrowding.
  6. Air fry: Cook for 10–13 minutes, shaking the basket or tossing halfway. The chicken should reach an internal temperature of 165°F (74°C) and the veggies should be tender with lightly charred edges.
  7. Warm tortillas: While the fajita mix finishes, warm tortillas in a dry skillet, microwave, or wrapped in foil in the air fryer for 1–2 minutes.
  8. Finish and serve: Taste and adjust salt or lime. Spoon into tortillas and add your favorite toppings. Serve immediately.
