Ingredients
  

  • 1 1/2 pounds boneless, skinless chicken breasts, thinly sliced (or use thighs for extra juiciness)
  • 3 bell peppers (mixed colors), thinly sliced
  • 1 medium red onion, thinly sliced
  • 2 tablespoons olive oil (or avocado oil)
  • 2 teaspoons chili powder
  • 1 1/2 teaspoons ground cumin
  • 1 teaspoon smoked paprika (regular paprika works too)
  • 3/4 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon dried oregano
  • 1/2 to 3/4 teaspoon kosher salt, to taste
  • 1/4 teaspoon black pepper
  • 1 lime, juiced (plus extra wedges for serving)
  • Warm tortillas (corn or flour), for serving
  • Optional toppings: chopped cilantro, sliced avocado, salsa, Greek yogurt or sour cream, shredded cheese

Method
 

  1. Preheat the air fryer: Set to 390–400°F (200–205°C) for 3–5 minutes. A hot basket helps the chicken sear fast.
  2. Slice the chicken and veggies: Cut chicken into thin strips about 1/2 inch wide. Slice peppers and onion to a similar thickness so everything cooks evenly.
  3. Make the seasoning: In a large bowl, combine chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, salt, and black pepper.
  4. Toss with oil and lime: Add chicken, peppers, and onion to the bowl. Drizzle with olive oil and the juice of 1 lime. Toss until evenly coated with the spice mix.
  5. Arrange in the basket: Spread the mixture in a single layer, avoiding heavy overlap. Cook in batches if needed to prevent steaming.
  6. Air fry: Cook for 10–13 minutes, shaking the basket or tossing halfway. Chicken is done when the thickest piece hits 165°F (74°C) and the peppers are tender with light char.
  7. Warm tortillas and prep toppings: While the fajitas cook, warm tortillas in a dry skillet or microwave under a damp towel. Prep your favorite toppings.
  8. Taste and finish: Add a pinch more salt if needed. Squeeze extra lime over the top for brightness.
  9. Serve: Load tortillas with chicken and veggies. Add cilantro, avocado, salsa, and a spoon of Greek yogurt or sour cream if you like.
