Real Chicago-style pizza is a deep-dish pizza that originated in Chicago, Illinois in the 1940s. It is made with a buttery, thick crust that is higher on the sides and has a crisp outer layer. The pizza is then filled with cheese and various toppings such as sausage, pepperoni, mushrooms, onions, and green peppers. The sauce is added on top of the toppings, and the pizza is baked for approximately 45 minutes. The result is a delicious, filling pizza that is meant to be enjoyed with a fork and knife. It is a true Chicago staple and a must-try for any pizza lover visiting the city.
