Preheat the air fryer to 400°F (200°C).
In a large mixing bowl, combine the chicken pieces, broccoli florets, chopped zucchini, bell pepper, onion, minced garlic, olive oil, Cajun seasoning, salt, pepper, Italian seasoning, and red chili pepper flakes (if using).
Toss everything together until the chicken and vegetables are well coated with the seasoning and olive oil.
Place the seasoned chicken and vegetables in the air fryer basket.
Air fry for 12-15 minutes, shaking the basket every 5 minutes to ensure even cooking.
Once the chicken is cooked through and the vegetables are tender, remove the air fryer basket from the fryer.
Garnish with fresh chopped parsley.
Serve the air fryer chicken and vegetables hot and enjoy!
