St. Louis–style pizza is a type of pizza in St. Louis, Missouri, and surrounding areas.[1] The pizza has a thin cracker-like crust made without yeast, topped with sweet tomato sauce and Provel cheese, and is cut into squares or rectangles rather than wedges.
St. Louis–style pizza is available at local restaurants and chains such as Imo's Pizza. Frozen St. Louis–style pizzas are sold at local supermarkets such as Schnucks and Dierbergs Markets.
In contrast to the larger pie-like wedges seen in other pizza styles, St. Louis–style pizza is cut into three- or four-inch squares, referred to as a party cut or tavern cut.[3][4][5]
It has been suggested that the square-cut was inspired by Ed Imo’s former profession as a tile-layer.[6] The smaller slices and rigid crust help to support the weight of its toppings.[7]
The tomato sauce is seasoned with more oregano than other styles of pizza,[1][2] and is sweeter, which is likely due to the influence of Sicilian immigrants upon Italian foods in St. Louis.[1]
