Ingredients

Blueberry Filling
- 1 1/2 cups blueberries, fresh or frozen
- 1/4 cup granulated sugar
- 1 tablespoon cornstarch
- 2 tablespoons water
- Zest and juice from 1/2 lemon
Turnovers
- 1 package (2 sheets) frozen puff pastry, thawed
- 1 large egg, beaten
Glaze
- 1 cup powdered sugar
- 2 tablespoons milk
Instructions
- Preheat the oven to 400°F. Position an oven rack in the lower third of the oven. Line two large baking sheets with parchment paper or silicone baking mats.
- Add the blueberries, granulated sugar, cornstarch, water, lemon zest, and lemon juice to a medium saucepan. Cook over medium heat until the mixture reaches a gentle simmer.
- Reduce the heat to medium-low and cook for 3–5 minutes, stirring frequently, until the blueberries burst and the mixture thickens to a jam-like consistency. Remove from the heat and let it cool slightly.
- Place the thawed puff pastry sheets on the prepared baking sheets. Cut each sheet into four equal squares, creating 8 squares total.
- Spoon 1–2 tablespoons of the blueberry filling into the center of each square. Avoid overfilling so the pastries seal properly.
- Fold one corner of each square diagonally toward the opposite corner to create a triangle. Press the edges together with your fingers or seal them with the tines of a fork.
- Cut a small slit in the top of each pastry to allow steam to escape. For especially flaky blueberry turnovers, place the filled pastries in the freezer for 10–15 minutes before baking.
- Brush the tops with the beaten egg. Bake for 15–20 minutes, or until the pastry is puffed and deeply golden.
- Let the turnovers cool on the baking sheet for about 5 minutes, then transfer them to a wire rack.
- Whisk the powdered sugar and milk together until smooth. Place parchment paper beneath the rack and drizzle the glaze over the cooled pastries. Allow the glaze to set before serving.

Tips & Tricks
- Keep the puff pastry cold: Cold pastry puffs better and produces more defined flaky layers.
- Cool the filling: Warm filling can soften the pastry and make sealing difficult.
- Don’t overfill: A modest amount of filling helps prevent leaks.
- Seal firmly: A fork makes an attractive edge while helping keep the blueberry filling inside.
- Use frozen blueberries: There is no need to thaw them before cooking.
- For a thicker filling: Cook it for another minute or two if it still looks loose.
- For a thinner glaze: Add a few drops of milk at a time until you reach your preferred consistency.

FAQ
Can I use frozen blueberries for blueberry turnovers?
Yes. Frozen blueberries can go directly into the saucepan without thawing. They may take a little longer to reach a simmer.
How do I keep turnovers from leaking?
Avoid overfilling the pastry and press the edges together firmly. Chilling the assembled turnovers before baking can also help them hold their shape.
Can I make these turnovers ahead of time?
Yes. Assemble the unbaked pastries and refrigerate them for several hours before baking, or freeze them for longer storage.
Why did my puff pastry not rise?
The pastry may have become too warm before baking. Keep it chilled while assembling and, when possible, freeze the filled turnovers for 10–15 minutes before placing them in the oven.
Can I make the glaze thicker?
Yes. Add more powdered sugar for a thicker glaze or a small amount of milk to loosen it.
Storage
Store baked turnovers at room temperature in a covered container for up to 2 days. For longer storage, refrigerate them for up to 5 days.
For freezing, place completely cooled turnovers in an airtight freezer-safe container or bag and freeze for up to 3 months. Thaw overnight in the refrigerator, then warm them in a 325°F oven until crisp and heated through.
