Gattò di Patate, also called gateau di patate in Italy, is a wholesome and rustic dish that’s both comforting and delicious. Golden and crusty on the outside yet soft and hearty on the inside, it’s made with mashed potatoes, cooked ham, and plenty of cheese.

As with many Italian classics, every family and region have its own twist. Some add salami or mortadella instead of ham, while others choose provolone or caciocavallo for a sharper, tangier flavor. You might even come across lighter versions with vegetables folded into the potato base.
A Bit of History
The story of gattò begins in Naples at the end of the 18th century, during the reign of Ferdinand I of Bourbon, king of the Two Sicilies. His wife, Maria Carolina, adored French cuisine and brought French chefs to court. Over time, however, the Neapolitans made the dish their own, replacing the original Gruyère with local cheeses like mozzarella di bufala. That’s how a French gâteau transformed into the beloved Neapolitan gattò.
Gattò di patate is most often served as a main course, but any leftovers are wonderful the next day as a starter or side dish, enjoyed warm or cold. However you prepare it or fill it, this is one of those dishes you’ll want to make again and again.
