Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
Gently mix sliced strawberries with granulated sugar and lemon juice in a bowl. Let them sit for a few minutes to release their juices.
1 pint fresh strawberries, 2 tablespoons granulated sugar, 1 tablespoon lemon juice
Unfold the thawed puff pastry on a lightly floured surface.
14.1 oz frozen puff pastry
Use a heart-shaped cookie cutter to cut out hearts from the puff pastry.

Place half of the heart cutouts on the prepared baking sheet. Top each with a spoonful of the strawberry mixture.
1 pint fresh strawberries, 2 tablespoons granulated sugar, 1 tablespoon lemon juice
Place the remaining heart cutouts on top of the strawberry-filled hearts, creating a "sandwich."
1 pint fresh strawberries, 2 tablespoons granulated sugar, 1 tablespoon lemon juice
Gently press the edges of each heart to seal. You can also use a fork to crimp the edges for a decorative look.
Brush the top of each heart with the beaten egg. This will give them a beautiful golden shine.
1 egg
Bake for 15-20 minutes, or until golden brown and the pastry is puffed.
Let the baked hearts cool on a wire rack. Dust with powdered sugar, if desired, and serve immediately.
