These delicious apple turnovers are perfect for when you want a warm, sweet treat. The flaky pastry filled with soft, cinnamon-spiced apples is a comfort food favorite. Whether you're baking for a special occasion or just indulging yourself, these turnovers are surprisingly easy to make. You can enjoy them fresh out of the oven or save them for a snack later.
Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a medium saucepan, melt the butter over medium heat. Add the diced apples, sugar, and cinnamon, and stir until the apples are coated.
Cook the apples for about 5 minutes, or until they begin to soften. Stir in the lemon juice and cornstarch, and cook for another 2-3 minutes, until the mixture thickens slightly. Remove from heat and allow the filling to cool.
Roll out the puff pastry on a lightly floured surface and cut it into 8 squares.
Place a spoonful of the apple filling in the center of each square. Fold the pastry diagonally to form triangles and press the edges together with a fork to seal.
In a small bowl, whisk the egg and water together to make an egg wash. Brush the tops of the turnovers with the egg wash.
Place the turnovers on the prepared baking sheet and bake for 20-25 minutes, or until the pastry is golden and flaky.
Let the turnovers cool for a few minutes before serving. Dust with powdered sugar if desired.
Use Granny Smith apples for a tart filling or Honeycrisp for a sweeter version. Add a pinch of nutmeg or cloves to the apple filling for extra warmth and spice. You can freeze the turnovers before baking and bake them directly from frozen. Just add a few extra minutes to the baking time. For extra flakiness, chill the assembled turnovers for 10 minutes before baking.
