Homemade apple turnovers are the ultimate fall treat! Flaky, golden puff pastry hugs a warm, spiced apple filling that’s cozy, comforting, and bursting with flavor. Perfect for breakfast, an afternoon snack, or dessert, these pastries bring a little bakery magic straight into your kitchen.
Line two baking sheets with parchment paper. Set aside.
Roll the puff pastry into a 10 inch by 10-inch rectangle, about ¼ inch thick. Cut into four 5-inch squares. Repeat with second puff pastry.
Place 6 squares on each baking sheet. Put the baking sheets in the refrigerator while preparing the filling.
For the filling, peel the apples, then grate them on a box grater. In a medium bowl, combine the grated apples with the sugar, lemon juice and salt.
Remove one baking sheet from the refrigerator. Working with one puff pastry square at a time, place 2 Tablespoons of apple filling in the center of the square. Dip your fingers in a small bowl of water and moisten the edges of the square. Take one corner of the square and fold it over to meet the opposite corner (creating a triangle). Use a fork to crimp the edges. Use a sharp knife to cut three small slits on top for steam to escape.
Repeat step 5 with remaining squares, then place the baking sheet in the refrigerator and repeat with the second sheet of dough squares.
Chill both baking sheets for at least 30 minutes and up to 24 hours.
Preheat oven to 375℉.
Add the cinnamon sugar coating. Whisk together the sugar and cinnamon. Remove one baking sheet from the refrigerator. Brush pastries with water and sprinkle with cinnamon sugar.
Bake at 375℉ for 30 to 35 minutes or until golden brown. Use a spatula to transfer the turnovers to a wire cooling rack. Serve warm or at room temperature.
