1. Prepare the Chicken: Start by patting the boneless, skinless chicken breasts dry with paper towels. This helps the seasonings adhere better and promotes a crispier exterior. Then, cut the chicken into 1-inch bite-sized pieces. Aim for uniform pieces so they cook evenly.

2. Season the Chicken: In a medium bowl, combine the cut chicken pieces with olive oil, minced garlic, grated Parmesan cheese, Italian seasoning, salt, and black pepper. Toss everything together thoroughly until all the chicken pieces are well coated.

3. Preheat the Air Fryer: If your air fryer requires preheating, set it to 375 F (190 C) and let it preheat for about 3-5 minutes. Preheating helps ensure even cooking and a nice sear.

4. Arrange in Air Fryer Basket: Place the seasoned chicken bites in a single layer in the air fryer basket. Avoid overcrowding the basket, as this can steam the chicken instead of crisping it. You may need to cook the chicken in two batches, depending on the size of your air fryer.

5. Air Fry the Chicken: Cook the chicken bites for 12-15 minutes, shaking the basket halfway through the cooking time (around the 6-7 minute mark). This ensures all sides get golden and crispy.

6. Check for Doneness: The chicken is done when it’s golden brown on the outside and cooked through, with an internal temperature of 165 F (74 C). A meat thermometer is the best way to confirm doneness.

7. Garnish and Serve: Once cooked, transfer the chicken bites to a serving platter. If desired, sprinkle with fresh chopped parsley for a touch of color and freshness before serving immediately.
