Start by mixing cream cheese, chopped jalapenos, and shredded mozzarella in a bowl. It should feel creamy and come together nicely.
Rub the chicken breasts with olive oil, Cajun seasoning, onion granules, garlic granules, salt, and pepper. Make sure to coat all surfaces to maximally infuse flavor.
Spoon the cheese mixture onto one side of the chicken and fold over. Ensure it looks like a cozy little pocket without overstuffing to prevent filling from escaping.
Use toothpicks to seal the edges of the chicken, keeping the filling inside. After sealing, it should look like a neat bundle.
Place the stuffed chicken in the air fryer basket and cook until it’s golden and crispy outside, maintaining a nice browned finish.
Allow the chicken to rest for a few minutes before slicing. This period allows the juices to settle back into the meat, enhancing juiciness.
