Preheat the oven to 375°F (190°C) and line a baking sheet with parchment paper.
In a mixing bowl, beat together the softened cream cheese, granulated sugar, egg, flour, lemon juice, and zest until smooth and creamy.
Unroll the crescent roll dough and separate it into triangles on a flat surface.
Spoon a generous tablespoon of the cheesecake mixture onto the wide end of each triangle.
Roll the dough from the wide end toward the pointed end, enclosing the filling and forming a crescent shape.
Place the rolled crescent rolls on the prepared baking sheet, spacing them about an inch apart.
Bake in the preheated oven for 12-15 minutes or until golden brown.
Let the rolls cool on the baking sheet for a few minutes before transferring them to a wire rack.
Dust with powdered sugar before serving, if desired.
