01 - Preheat air fryer to 360°F for 5 minutes.
02 - Divide pizza dough into 4 equal sections. Roll each portion into a circle about 6 inches in diameter on a lightly floured surface.
03 - In a mixing bowl, combine cooked chicken, mozzarella, Parmesan, Alfredo sauce, baby spinach if using, minced garlic, Italian seasoning, salt, and black pepper. Mix thoroughly.
04 - Distribute one-fourth of the filling onto half of each dough circle, leaving a 1/2-inch border at the edge.
05 - Sprinkle cheddar cheese over filling for additional crispiness, if desired.
06 - Fold dough over filling to create a half-moon shape. Firmly pinch the edges to seal, then use a fork to crimp for extra security.
07 - Brush tops of calzones with beaten egg, then lightly drizzle or brush with olive oil.
08 - Place calzones in the air fryer basket in a single layer. Cook in batches if needed to avoid overcrowding.
09 - Air fry at 360°F for 12 to 15 minutes, until calzones are golden and the crust is crisp.
10 - Allow calzones to cool for 2 to 3 minutes before serving to ensure optimal texture.
