Unroll the pie crusts or roll 2 homemade pie crusts to be ⅛-inch thick.

Use a 4½ to 5-inch-diameter round cutter to cut 4 circles from each of the crusts (8 total).

Place 4 to 5 slices of apple and about 1½ tablespoons of juices from the pie filling on one-half of each pie dough circle, leaving a ½-inch border.

In a small bowl, whisk together the egg and 1 tablespoon of water. Brush the edges of each circle with the egg wash.

Fold the empty halves of the dough over the pie filling to create 8 half circles. Crimp the edges with a fork and brush the outside of each with the egg wash.

With a paring knife, cut 3, ½-inch slits in the top of each hand pie. Sprinkle all over with the coarse sugar.

Place 2 to 4 pies in the basket of an air fryer. Air fry at 350°F for 10 to 12 minutes. Cool on a wire rack.

Repeat with the remaining hand pies. Serve them warm.
