If you enjoy a bit of heat, try making spicy Cajun chicken breasts in the air fryer. Season the chicken breasts with a Cajun spice blend or a mixture of paprika, garlic powder, onion powder, cayenne pepper, salt, and black pepper. Preheat the air fryer to 375°F (190°C). Place the chicken breasts in the air fryer basket and cook for 12-15 minutes, flipping once. The result will be perfectly seasoned and spicy chicken breasts with a crispy exterior.
