In a large mixing bowl, add all the ingredients, except for the potstickers, and mix well.
Lightly wet your hands and place the potsticker wrappers on a flat surface. Add a spoonful of the filling in the center and fold over. Use your fingers to pinch the top several times, to decorate.
Lightly brush water on the exterior of the potstickers. Add them to an air fryer basket and air fryer at 200C/400F for 6-7 minutes, turning halfway through.
Remove the potstickers from the air fryer and serve immediately.
To air fry frozen dumplings or potstickers, simply increase the cooking time by 2 minutes and shake the air fryer basket several times throughout. TO STORE: Leftovers can be stored in the refrigerator, covered, for up to five days. TO FREEZE: Potstickers can be frozen either uncooked or cooked. Place them in an airtight container and store it in the freezer for up to two months. TO MAKE AHEAD: Make the potstickers up to five days in advance and keep them stored in the refrigerator. When ready to air fry, lightly brush the exterior with some water before air frying them.
