Detroit-style pizza is a rectangular pizza with a thick crust that is crispy and chewy. It is traditionally topped with Wisconsin brick cheese, then tomato sauce layered on top of the other toppings (rather than directly onto the dough). This style of pizza is often baked in rectangular steel trays designed for use as automotive drip pans or to hold small industrial parts in factories. The style was developed during the mid-twentieth century in Detroit before spreading to other parts of the United States in the 2010s. The dish is one of Detroit's iconic local foods.
