Preheat your oven to 400°F (200°C) to ensure even baking and a golden color.
On a lightly floured surface, roll out each sheet of puff pastry if needed to smooth out creases, about 1/8-inch thick.
Spread a generous amount of the prepared spinach and artichoke dip evenly over each puff pastry sheet, leaving a small border around the edges.
Sprinkle shredded parmesan cheese evenly over the dip to add flavor and help bind the filling.
Starting from one edge, tightly roll the puff pastry sheet up, pinching seams to seal the filling inside.
Slice the rolled pastry into 1-inch thick pinwheels using a sharp knife or pizza cutter. Place on a baking sheet lined with parchment paper.
Bake the pinwheels for 15-20 minutes until golden brown and puffed, watching carefully to prevent burning.
Remove from oven, let cool a few minutes, and serve warm or at room temperature.
