Preheat your oven to 400°F (205°C) and line a baking sheet with parchment paper.
Unroll the puff pastry and cut it into 8 rectangles. Gently score a border around each one without cutting all the way through.
In a bowl, mix the cream cheese, sugar, and vanilla until smooth.
Spread a spoonful of the cream cheese mix inside the scored border of each rectangle.
Top with a small dollop of strawberry preserves and add a few slices of fresh strawberries.
Brush the edges with the beaten egg and sprinkle with coarse sugar.
Bake for 15–18 minutes or until golden brown and puffed.
Cool slightly before serving—if you can wait!
