Craving a bakery-style treat without the hassle? These Blueberry Turnovers with Puff Pastry are the answer! With a golden, flaky crust and a luscious homemade blueberry filling, they’re unbelievably easy to make—and even easier to devour.
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a medium bowl, mix the blueberries, granulated sugar, cornstarch, and lemon juice until the blueberries are well coated.
On a lightly floured surface, unfold the puff pastry sheets and cut each sheet into 4 equal squares.
Place about 2 tablespoons of the blueberry mixture in the center of each puff pastry square.
In a small bowl, mix the beaten egg with the water. Brush the edges of the pastry squares with the egg wash.
Fold each square into a triangle, pressing the edges together with a fork to seal.
Place the turnovers on the prepared baking sheet. Brush the tops with the remaining egg wash and sprinkle with coarse sugar if desired.
Bake for 15-18 minutes, or until the turnovers are golden brown and puffed. Serve warm.
