Take your puff pastry out of the freezer to thaw. (You can either buy the already cut puff pastry rounds or thaw out one sheet of frozen puff pastry. If using sheet puff pastry, unfold the layers and cut out rounds with a biscuit cutter.) Place puff pastry rounds on a baking tray with parchment and brush with butter. Optional -Sprinkle with freshly grated Parmesan cheese and freshly ground pepper (you can season them with anything you like or nothing at all). Bake in a 400 degree F oven for 5-7 minutes. They will puff up and be perfect for topping your soup. If you are using the already cut puff pastry shells, follow the package directions for baking.
