Sicilian pizza is a type of pizza that originated in Sicily, Italy. It is known for its rectangular shape and thick, fluffy crust. Some synonyms for Sicilian pizza include Grandma-style pizza, square pizza, thick-crust pizza, and Detroit-style pizza. Grandma-style pizza is similar to Sicilian pizza in terms of its thick crust, but it is usually round and has a thinner layer of sauce. Square pizza refers to the shape of the pizza, which is a square rather than a circle. Thick-crust pizza is self-explanatory, while Detroit-style pizza is a variation of Sicilian pizza that is baked in a rectangular pan, with toppings such as cheese and sauce added in reverse order.
