Chicago-style deep-dish pizza is a unique type of pizza that originated in Chicago in the 1940s. Unlike traditional pizzas, it features a thick, buttery crust that is baked in a deep, round pan, resembling a pie. The crust is layered with cheese, toppings, and a chunky tomato sauce, creating a hearty meal. This pizza is typically served in slices that are much thicker than regular pizza, making it a filling option. The combination of the crispy outer crust and the gooey cheese inside makes it a favorite among many pizza lovers.
