Deep Dish is a style of pizza that originated in Chicago in the 1940s. It is characterized by its thick, buttery crust that is baked in a deep pan, allowing for a generous amount of toppings. The pizza is typically layered with cheese, meats, vegetables, and a chunky tomato sauce on top, creating a hearty meal. Unlike traditional thin-crust pizzas, Deep Dish has a more pie-like structure, making it a filling option. The cooking method involves pre-baking the crust before adding the ingredients, which helps achieve a crispy exterior while keeping the inside soft and gooey.
