No Sicilian and deep-dish pizza is different. A deep dish is also known as Chicago-style pizza. It is almost like a pie, but not really a pie. It is baked in a deep-dish pan this is oiled generously to get a crispy crust. The slices can be 2-inch thick. The dough is usually made of cornmeal, semolina, and food color to get a yellow-colored crust. It has a unique texture.
