01 - Preheat the air fryer to 360°F for 5 minutes.
02 - Divide pizza dough into 4 equal portions. Using a rolling pin, roll each portion into a 6-inch circle on a lightly floured surface.
03 - In a mixing bowl, combine chicken, mozzarella, Parmesan, Alfredo sauce, spinach if desired, garlic, Italian seasoning, salt, and black pepper. Mix ingredients thoroughly.
04 - Spoon one-fourth of the filling mixture on half of each dough circle, leaving a 1/2-inch margin along the edge.
05 - For extra crispiness, sprinkle a portion of cheddar cheese over the filling.
06 - Fold dough over filling to create a half-moon. Pinch edges firmly to seal, then crimp with a fork for additional security.
07 - Brush the tops with beaten egg, then apply olive oil lightly over each calzone using a pastry brush.
08 - Arrange calzones in the air fryer basket in a single layer. Cook in batches if needed.
09 - Air fry at 360°F for 12 to 15 minutes until golden and crisp.
10 - Allow calzones to cool for 2 to 3 minutes before serving.
