Preheat your air fryer to 375 degrees F for optimal cooking results.

Spray or brush the raw chicken breasts with olive oil, ensuring an even coating. Sprinkle the spicy cajun seasoning, salt and pepper generously on both sides of the chicken breasts, pressing the spices onto the surface for maximum flavor.

Place chicken breasts in a single layer in the air fryer basket. Avoid overcrowding to allow proper air circulation.

Cook the Cajun-seasoned chicken breasts in the air fryer for 20-25 minutes, flipping halfway through. Adjust the cooking time based on the thickness of your chicken breasts and your specific air fryer model.

Use a meat thermometer to ensure the chicken reaches an internal temperature of 165°F (74°C). This guarantees a safe and perfectly cooked Cajun masterpiece.

Allow the Cajun chicken breasts to rest for 2-3 minutes before slicing. This ensures juicy, flavorful bites. Garnish with fresh parsley for a burst of color and freshness.
