Prepare the Air Fryer: Preheat your air fryer to 375°F (190°C). Lightly spray the basket with olive oil to prevent sticking and ensure even crispiness on the chicken strips.
Make the Coating Mixture: In a shallow bowl, mix the breadcrumbs, Parmesan cheese, salt, and pepper until well combined. This flavorful mixture will create a crispy exterior on the chicken strips.
Bread the Chicken: Dredge each chicken strip in flour first, ensuring it's fully coated. Then dip it into the beaten egg, allowing excess to drip off. Finally, coat it thoroughly in the breadcrumb mixture, pressing gently so the coating adheres well to create a crispy crust.
First Air Fry: Place the coated chicken strips in a single layer in the air fryer basket, leaving space between each piece for proper air circulation. Overcrowding will result in uneven cooking.
Cook Until Golden: Air fry for 8 to 10 minutes, flipping halfway through the cooking process, until the chicken is golden brown and crispy on all sides and fully cooked through.
Prepare the Buffalo Sauce: While the chicken cooks, warm the buffalo sauce in a small saucepan over medium heat until it's hot but not boiling. The warm sauce will coat the chicken better than cold sauce.
Buffalo Coat the Chicken: Once the chicken strips are done, dip each one into the buffalo sauce, coating them completely. Allow any excess sauce to drip off before moving to the next step.
Stuff with Cheese: Carefully stuff each buffalo-coated chicken strip with a piece of mozzarella cheese. You can make a small slit in each strip to insert the cheese or wrap the chicken around the cheese.
Second Air Fry: Return the stuffed chicken sticks to the air fryer and cook for another 3 to 4 minutes, until the cheese inside is melted and gooey, and the exterior is extra crispy.
Serve Hot: Remove from the air fryer and serve immediately while the cheese is still hot and stretchy. Pair with ranch or blue cheese dressing for dipping to balance the spice of the buffalo sauce.
