Pat the chicken breasts dry with a paper towel. This helps the seasoning stick and prevents excess moisture from steaming the chicken instead of crisping it.

In a small bowl, combine Cajun seasoning, garlic powder, smoked paprika, salt, and pepper. Rub the chicken breasts with olive oil, then coat them evenly with the spice mixture, making sure every surface is covered.

Preheat your air fryer to 375°F (190°C) for about 3 minutes. Place the seasoned chicken breasts in the basket in a single layer, leaving a little space around each piece for air circulation.

Cook for 9–10 minutes, then flip and cook for another 7–9 minutes, or until the internal temperature reaches 165°F (74°C). The exact time may vary depending on the thickness of your chicken breasts.

Let the chicken rest for 3–5 minutes before slicing. This keeps the juices locked in so every bite stays tender and flavorful.
