Spray the air fryer basket with nonstick spray. Set aside.
Lay out the wonton wrappers on a clean surface.
25 wonton wrappers
Working 1 at a time, add 1 teaspoon of marinara sauce, a pinch (about 2 teaspoons) of mozzarella cheese, and 1-2 teaspoons of pizza toppings of your choice. Repeat until all wonton wrappers are topped.
1 cup marinara sauce, 2 cups shredded mozzarella cheese, Pizza toppings
Very lightly brush the edges of each wonton wrapper with water. Fold 2 opposite corners of the wrapper into the center, then fold the remaining 2 corners over the top of the first 2. This should create a square shape with the filling fully contained inside. Repeat until all pizza rolls are shaped.
Working in batches, place the pizza rolls seam-side down into the air fryer. Make sure not to overcrowd the basket.
In a small bowl, whisk the egg and water together. Brush the tops of the pizza rolls with the egg wash.
1 large egg, 1 teaspoon water
Cook the pizza rolls at 400°F for 8-10 minutes or until the pizza rolls are golden brown. Repeat until all pizza rolls are cooked and serve warm with marinara sauce for dipping.
To keep cooked pizza rolls warm while the remaining rolls finish cooking, place onto a baking sheet lined with parchment paper in a 250°F oven for up to 30 minutes.
