Preheat the air fryer to 360º F while you prepare the patties.
In a bowl, mix together the ground chicken, onion, parsley, salt, garlic powder, paprika, and black pepper until evenly blended.
1 pound ground chicken, ½ small onion, 1 Tablespoon chopped parsley, 1 teaspoon salt, 1 teaspoon garlic powder, ½ teaspoon paprika, ¼ teaspoon black pepper
Form into 4 equal size patties. The ground chicken mixture will be sticky, so you can spray your hands with non-stick spray to help form the patties if necessary.
Place the patties in your hot air fryer and cook at 360º F for 9 minutes. After 9 minutes, place a piece of cheese over each one, and cook for 1 more minute.
4 slices cheddar or favorite cheese
Remove from the air fryer and serve on buns with desired toppings.
