Which city is known for deep-dish pizza? Chicago is the American city most closely associated with deep-dish pizza.

Chicago-style deep-dish pizza is baked in a tall, oiled pan that gives the crust a high edge. Unlike a typical flat pizza, its ingredients are often layered with cheese and toppings beneath chunky tomato sauce, helping protect the cheese during the longer bake.

The style is widely associated with Pizzeria Uno, which opened in Chicago in 1943 under Ike Sewell and Richard Riccardo. The restaurant's recipe helped establish the city's signature deep-dish tradition, while later Chicago institutions such as Lou Malnati's and Gino's East developed their own recognizable versions.

Chicago has more than one important pizza tradition. Tavern-style pizza, a thin and crisp crust cut into squares, is also deeply rooted in the city and may be more popular with some local residents. Detroit and St. Louis have distinctive pizza styles of their own, but deep-dish is the canonical Chicago association.
