01 - Preheat oven to 375°F. Lightly grease a mini muffin tin or tartlet pans with cooking spray or butter.
02 - Unroll the puff pastry and cut out 12 circles using a 2.5-inch round cutter. Press each circle gently into the prepared tin, shaping to form cups.
03 - Brush the pastry cups with beaten egg. Prick the bottoms with a fork to prevent puffing during baking.
04 - Bake for 12–14 minutes until golden brown and crisp. Cool completely in the pan before carefully removing.
05 - In a mixing bowl, beat cream cheese, heavy cream, lemon juice, lemon zest, powdered sugar, and salt until smooth and creamy.
06 - Spoon or pipe the lemon cream filling into the cooled tartlet shells, filling just below the rim.
07 - Top each tartlet with chopped chives, microgreens or dill, and lemon zest curls. Serve chilled or at room temperature.
