Grease a medium baking pan with a little butter or oil and lay out one sheet of puff pastry from the package.

In a bowl, combine the heavy cream, cheeses, and a little black pepper (do not add salt, as regato cheese is already salty).

After mixing the ingredients, pour them into the baking pan and cover with the other puff pastry sheet, brushing the top with a little oil.

Bake in a preheated oven at 350–400°F (180–200°C) for about 30 minutes or until golden brown.
