Stuffed pizza is an American pizza that started its way to popularity in Chicago a bit later than the deep-dish pizza, with which it shares many similarities. It has a more solid and smooth crust than the deep-dish pizza. The dough is also a bit drier and sweeter.
The pizza is topped with a generous amount of cheese and various other ingredients such as vegetables and crumbled sausages. The next thing that goes on top is another thin layer of dough (hence the name stuffed pizza), usually with slits cut into it so that it lets moisture out while it cooks.
