Preheat the air fryer to 375°F (190°C).
In a large bowl, combine the ground chicken, breadcrumbs, Parmesan, onion, garlic, salt, pepper, smoked paprika, and egg.
Using your hands, form the mixture into bite-sized balls, approximately 1 inch in diameter.
Spray the air fryer basket lightly with cooking spray to prevent sticking.
Arrange the formed bites in the basket in a single layer, making sure they aren’t touching.
Cook the bites for 10-12 minutes, flipping halfway through, until golden brown.
Check for doneness by ensuring the internal temperature reaches 165°F (74°C).
Once cooked, remove the bites from the air fryer and let them cool slightly before serving.
