If you enjoy a bit of heat, this spicy Cajun air fryer chicken breast recipe is perfect for you. Use the food processor to create a Cajun spice blend by combining paprika, cayenne pepper, garlic powder, onion powder, dried thyme, and salt. Rub the spice blend onto the chicken breasts and let them marinate for at least 30 minutes. Place the seasoned chicken breasts in the air fryer and cook at 380°F for about 15-20 minutes until they are cooked through and crispy. The result is a spicy and flavorful chicken breast with a nice kick.
