Detroit-style pizza has gone from a regional curiosity to one of the most widely imitated pizza styles in the country over the past decade — but its origin story is genuinely tied to the city's industrial history in a way most pizza styles aren't.
The automotive-parts-tray origin story
Detroit-style pizza is generally credited to Buddy's Pizza, which reportedly began baking pizza in the 1940s using square, blue steel trays originally designed to hold small automotive parts on factory assembly lines — a detail that ties the pizza's entire shape and format directly to Detroit's identity as a manufacturing city. That pan shape, deep and rectangular with straight sides, is still the defining physical trait of the style today.
What actually makes it different from other rectangular pizzas
- The crispy cheese edge — cheese is spread all the way to the pan's edges, where it caramelizes against the hot steel into a distinctive crispy, almost fried border that's considered the style's signature feature
- Sauce on top, in stripes — unlike most pizza styles, sauce is typically applied after baking, in stripes across the top of the cheese, rather than underneath it
- A thick, airy crust — closer in texture to focaccia than a typical pizza crust, a result of the deep pan and specific dough hydration
Why it spread nationally so recently
Detroit-style pizza stayed largely a regional specialty for decades before experiencing a genuine national boom starting roughly in the mid-2010s, as pizzerias outside Michigan began adopting the format — a spread that food writers and industry observers have specifically credited to renewed national interest in regional American pizza styles more broadly during that period.
How it compares to Chicago deep dish
Despite both being thick, pan-based Midwestern styles, Detroit and Chicago deep dish are genuinely different: Detroit uses a rectangular steel pan and puts sauce on top after baking, while Chicago deep dish uses a round pan and layers cheese, then toppings, then a chunky sauce, before baking everything together. They're often mentioned in the same breath but aren't interchangeable styles.
