Blackberry Puff Pastry Galette is an easy summer dessert that uses frozen puff pastry instead of homemade pie dough for a crisp, buttery crust. Fresh blackberries are tossed with honey, vanilla, lemon, and salt, then baked until they naturally thicken into a soft, juicy filling without added starch. The butter-enriched egg wash gives the pastry rich flavor and a golden finish.

Instructions
Preheat the oven to 375°F (190°C). Line a medium baking sheet with parchment paper.
In a medium bowl, gently toss the blackberries with the vanilla extract, lemon juice, honey, and salt until evenly coated. Set aside.
2 cups (290 g) fresh blackberries, 1 tsp (5 ml) vanilla extract, ½ tbsp (8 ml) fresh lemon juice, 2 tbsps (42 g) honey, ½ tsp (3 g) kosher salt
Melt the butter and let it cool for 1 to 2 minutes. Whisk it together with the egg until smooth.
3 tbsps (43 g) unsalted butter
Unfold the thawed puff pastry onto the prepared baking sheet. Brush the entire surface of the pastry with the butter egg wash.
1 large egg
Spoon the blackberry mixture into the center of the puff pastry, leaving a 1½ to 2-inch (4 to 5 cm) border around the edges.
1 sheet (8-9 oz / 225-255 g) frozen puff pastry
Fold the edges of the pastry over the filling, overlapping and gently pressing the folds together as needed. Brush the folded edges with the remaining butter egg wash.
Bake for 25 to 30 minutes, or until the pastry is deep golden brown and the blackberry filling is bubbling.
Let the galette cool for 5 to 10 minutes before slicing. The filling will continue to thicken as it cools. Serve warm with vanilla ice cream, if desired.
Notes
Let the melted butter cool slightly before whisking it with the egg so it doesn't begin cooking the egg.
Keep the puff pastry cold until you're ready to assemble the galette for the flakiest results.
The blackberry filling will look loose when it comes out of the oven but thickens naturally as it cools.
Store leftovers covered in the refrigerator for up to 3 days.
Reheat in a 350°F (175°C) oven for 8 to 10 minutes until the pastry is crisp again.
