Ingredients

For the pastry:

• 1 sheet puff pastry, thawed
• 1 egg
• 1 tablespoon water
• 1 tablespoon coarse sugar or granulated sugar, for topping

For the blueberry filling:

• 2 cups fresh or frozen blueberries
• 1/4 cup granulated sugar
• 1 tablespoon cornstarch
• 1 tablespoon lemon juice
• 1 teaspoon lemon zest
• 1/2 teaspoon vanilla extract

Optional glaze:

• 1/2 cup powdered sugar
• 1 to 2 teaspoons milk or lemon juice

Instructions

1. Prepare the blueberry filling

In a small saucepan over medium heat, combine the blueberries, granulated sugar, cornstarch, lemon juice, lemon zest, and vanilla extract. Stir gently and cook for about 4 to 6 minutes, or until the berries begin to burst and the mixture thickens slightly. Remove from the heat and let it cool completely. The filling should be thick enough to spoon without running too much.

2. Prepare the puff pastry

Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

Lightly flour your work surface and unfold the thawed puff pastry sheet. If needed, roll it out just a little to smooth the folds. Cut the pastry into 6 rectangles or 8 smaller squares, depending on the size you want.

3. Fill the pastries

Place a spoonful of the cooled blueberry filling in the center of each pastry piece, leaving a border around the edges. You can either:

• fold them over to make turnovers, pressing the edges with a fork, or
• leave them open-faced like danishes by lightly scoring a border around the edge without cutting all the way through.

4. Make the egg wash

In a small bowl, whisk together the egg and water. Brush the edges of each pastry with the egg wash, then sprinkle the tops lightly with sugar for extra shine and crunch.

5. Bake

Transfer the pastries to the prepared baking sheet and bake for 15 to 20 minutes, or until the puff pastry is deeply golden, puffed, and crisp.

6. Cool and glaze

Let the pastries cool for at least 10 minutes before adding glaze. If using the glaze, whisk together the powdered sugar and enough milk or lemon juice to make a smooth drizzle, then spoon it over the cooled pastries.

Serving Suggestions

Tips for the Best Blueberry Puff Pastry

• Keep the puff pastry cold for the flakiest result.
• If using frozen blueberries, there’s no need to thaw them first.
• Let the blueberry filling cool completely before adding it to the pastry so the dough stays crisp.
• Don’t overfill the pastries, or the filling may spill out while baking.
• For an extra bakery-style touch, finish with a light dusting of powdered sugar before serving.

Storage

Store leftover pastries in an airtight container at room temperature for 1 day or in the refrigerator for up to 3 days. Reheat in the oven for a few minutes to bring back the crisp
