Preheat your air fryer to 375 degrees F for a few minutes. This ensures the chicken cooks evenly and achieves that perfect golden-brown crispiness.

Drizzle a little olive oil over the chicken breasts or use a cooking spray for an even coating. Season with your favorite blend of spices, ensuring both sides are well-covered. 

Place the seasoned frozen chicken breasts in a single layer in the air fryer basket. Avoid overcrowding to allow proper air circulation, which ensures an even cook.

Cook the frozen chicken breasts for 16-20 minutes, flipping them halfway through. Cooking times may vary based on your specific air fryer model, so adjust accordingly.

Using a meat thermometer, ensure the chicken reaches an internal temperature of 165°F (74°C) to guarantee it's fully cooked.

Allow the air-fried chicken breasts to rest for a few minutes before slicing. This helps retain the juices for a juicy interior. Garnish with fresh herbs for a burst of flavor.
