Preheat oven to 400 degrees and line a baking sheet with parchment paper or foil (in case any of the filling leaks out of the turnovers, the parchment paper or foil will make for easy clean-up).

Unfold your thawed puff pastry dough. With a sharp knife, cut the dough into four equal squares. Set aside.

In a mixing bowl, mix whipped cream cheese, lemon curd, lemon zest, and 3 Tbsp of sugar together until well combined.

Place about 2 Tbsp of filling into the corner of each square of puff pastry. Fold the pastry diagonally, and crimp the edges with a fork. Brush the tops and edges of each turnover with egg wash, and sprinkle each with the remaining 1 Tbsp of sugar.

Bake for 18-20 minutes, or until pastry is puffed and golden brown.

Allow to cool for a few minutes and enjoy!
