Preheat the oven to 400°F. Lightly grease 2 mini muffin tins (makes 24).
Unfold the puff pastry sheet and stab it all over with a fork. Cut into 25 squares. Press 24 of the squares into the muffin wells (you don’t need the last one).
Mix together the cream cheese, smoked salmon, and dill. Stir until combined. Divide the mixture among the 24 wells.
