Step-by-Step Instructions

Step 1: Prep the Chicken and Vegetables

1. Slice the Chicken: Slice the chicken breasts against the grain into uniform ½-inch thick strips. Keeping them evenly sized ensures even cooking.

2. Slice the Veggies: Core and seed the bell peppers, then slice them into ½-inch strips. Peel the onion and slice it into strips of similar thickness.

Step 2: Season the Fajita Mix

1. Combine Spices: In a small bowl, mix together the chili powder, cumin, garlic powder, onion powder, smoked paprika, oregano, salt, black pepper, and optional cayenne pepper.

2. Coat Ingredients: In a large bowl, place the sliced chicken, bell peppers, and onions. Drizzle evenly with the 2 tablespoons of oil and fresh lime juice.

3. Mix: Sprinkle the spice mixture over the chicken and vegetables. Use tongs or clean hands to toss everything thoroughly until every piece is coated in spices and oil.

Step 3: Preheat the Air Fryer

1. Set your air fryer to 400°F (200°C) and let it preheat for 3 to 5 minutes. Preheating ensures immediate searing when the food hits the basket.

Step 4: Air Fry the Fajitas

1. Load the Basket: Transfer the seasoned chicken and vegetable mixture into the air fryer basket. Spread it out as evenly as possible. (If using a smaller 3-quart air fryer, cook in two separate batches to avoid overcrowding).

2. Set Timer: Set the air fryer to cook at 400°F (200°C) for 12 to 15 minutes.

3. Shake Halfway: At the 6-minute mark, open the basket and use tongs to shake or turn the chicken and veggies. This prevents burning and allows even browning.

4. Check Doneness: The chicken is done when it reaches an internal temperature of 165°F (74°C) on a meat thermometer and the peppers are tender with lightly charred edges.

Step 5: Warm the Tortillas & Assemble

1. While the fajitas rest for 2 minutes in the basket, wrap your tortillas in foil and warm them in the air fryer at 350°F (175°C) for 2 minutes (or microwave them wrapped in paper towels for 20 seconds).

2. Squeeze fresh lime juice over the warm fajita mix in the basket and sprinkle with chopped cilantro.

3. Serve immediately on warm tortillas with your favorite toppings.

Chef’s Tips for Success

• Don’t Overcrowd the Basket: For best results, air circulation is key. Overcrowding will cause the veggies and chicken to steam rather than roast and char.

• Uniform Slicing: Try to slice both the chicken and vegetables into uniform strips so they cook at the exact same rate.

• Adding Char: If you prefer extra charred edges, toss the chicken and veggies at 12 minutes and add an extra 2–3 minutes at maximum air fryer temperature (400°F–425°F).

Variations & Customizations

• Fajita Bowls (Low-Carb / Keto): Skip the tortillas and serve the air-fried chicken and veggies over a bed of cilantro-lime cauliflower rice or salad greens.

• Steak or Shrimp Swap:

  • Steak Fajitas: Use skirt or flank steak cut into strips. Reduce cooking time to 8–10 minutes at 400°F for medium-rare/medium.

  • Shrimp Fajitas: Cook the veggies alone for 6 minutes first, then add raw peeled shrimp and cook together for an additional 5–7 minutes until cooked through.

• Vegetarian / Vegan: Replace chicken with sliced Portobello mushrooms, black beans, or firm cubed tofu.
