Puff pastry filled with ricotta, mozzarella, and salami is a Neapolitan bakery classic. This protein-packed mediterranean pastry is a quick family snack that satisfies every craving.
Preheat oven to 375°F (190°C) and line a baking sheet with parchment paper for even heat distribution.
Combine ricotta, mozzarella (torn or diced), chopped salami, grated Parmesan, egg, black pepper, nutmeg, and sea salt in a large bowl, mixing until unified but maintaining some texture.
Unfold one puff pastry sheet onto the baking sheet and spread the cheese-salami mixture evenly, leaving a 0.5-inch border all around.
Moisten the border with water, then cover with the second pastry sheet, pressing edges tightly to seal and crimp with a fork.
Pierce the top with a fork in several spots for steam release, brush the surface lightly with beaten egg for shine, and bake for about 35 minutes, rotating the pan halfway for even browning.
Cool for 10 minutes to allow the filling to set and slice into portions while warm but not hot.
