Chicago-style pizza, an innovative style of deep-dish pizza, with inverted layers of ingredients (compared with thin-crust pizza), that was developed in Chicago, Illinois, in the 1940s and is one of the culinary hallmarks of the city.
Hundreds of years ago in Naples, Italy, pizza (its name related to the Greek pita, or flatbread) was developed in its classic form as a thin layer of dough covered with tomato sauce and topped with mozzarella cheese and basil, a construction known as pizza Margherita. When Neapolitans began to arrive in North America in the 19th century, pizzas grew larger and had more abundant and various toppings, including pepperoni, sausage, onions, and mushrooms.
The Neapolitan pizza brought to Chicago underwent a transformation of a different sort at the Pizzeria Uno restaurant, which opened in 1943 and was owned by Ike Sewell. The pizzeria used a crust that was more appropriate to a pie (whence “pizza pie”) than a flatbread. Within that “pie shell,” a profusion of toppings were placed on a layer of mozzarella cheese, and the tomato sauce was layered on the top (not the bottom) of the toppings. The pizza pie was baked in a round cake pan coated with olive oil, which lent a crunchy quality to the crust. A topping of some Chicago-style pizzas is Italian beef with giardiniera, a blend of pickled peppers and other vegetables combined to lend a hot spicy tang to the food.
Some histories attribute the invention of Chicago-style pizza to members of the Malnati family who were associated with Pizzeria Uno, including Rudy Malnati, Sr., and his son Lou Malnati, who opened his own restaurant in Chicago’s suburb of Lincolnwood in 1971. To complicate matters, Rudy Malnati, Jr., claimed ownership of an original family recipe for the upside-down pizza. It is unlikely that the truth will ever completely emerge, but now hundreds of Chicago-style pizza restaurants can be found, both in the city and far outside Chicago, often opened by Chicagoans.
For all the popularity of Chicago-style pizza, however, most Chicagoans would seem, by volume of sale, to prefer a thin-crust pizza to the version that bears the city’s name. Compared with thin-crust pizza, Chicago-style pizza contains higher levels of calories, carbohydrates, and fat and should be eaten in moderation.
