Fugazzeta is a mozzarella-stuffed pizza topped with onions, originating from Argentina. The onions should be thinly sliced, and they can be either raw or sautéed. The dough is usually made with milk, water, yeast, flour, sugar, salt, and olive oil.

It is believed that fugazzeta evolved from fugazza, a non-stuffed pizza that is topped with onions, and fugazza itself evolved from the Italian focaccia. When sautéed vegetables such as spinach are added to fugazzeta, it is then called fugazzeta de verdura, and when slices of ham are added to fugazzeta, it is known as fugazzeta con jamon.
