Detroit Style: Why the Square Pizza Took Over

Born in a bar, baked in an auto pan

The origin is 1946, at Buddy's Rendezvous, a neighborhood tavern on Detroit's east side. Owner Gus Guerra wanted to serve a Sicilian-style square like the ones from his wife's family recipe, and — the detail that made history — baked it in heavy blue steel pans commonly told of as coming from local automotive plants, where trays like them carried small parts and hardware.

The pan turned out to be a cheat code. Blue steel is thick, holds heat like cast iron, and seasons over time like a good skillet — decades-old pans are treated like family assets in Detroit shops. In a 500-550°F oven, the pan essentially fries the bottom and sides of the dough in oil while the top bakes, producing a crust that's airy like focaccia inside and crackling like a fritter outside. No stone, no dome, no $40,000 imported oven — just Motor City metallurgy.

The frico edge: the best part of any pizza, period

The signature isn't the shape — it's the perimeter. Detroit style spreads cheese all the way to the pan walls, no crust border left bare. Against the hot steel, that cheese fries into frico — the Italian term for crisped, caramelized cheese — forming a deep-brown, crunchy, salty crown around every edge piece.

The traditional cheese matters too: Wisconsin brick cheese, a high-fat, mild, buttery cheese that melts creamy and fries crisp without turning bitter. Shops that can't source brick blend mozzarella with white cheddar or jack to fake the fat content. And the sauce goes on top — ladled in stripes over the baked cheese, the "red top" — so the crust below stays crisp instead of steaming soggy under tomato. Cheese under sauce: where have you heard that before? Detroit quietly runs the same play as deep dish, in one-third the bake time, as covered in New York vs Chicago Deep Dish.

The technique: why it's hard to make badly (and easy to fake)

Real Detroit style is a multi-day project. The checklist that separates it from "thick square pizza":

• High-hydration dough, cold-fermented 24-72 hours — that's where the open, airy crumb comes from. The science is in Pizza Dough: Fermentation and Why It Matters.
• Proofed in the pan, in oil, for hours — the dough relaxes into the corners on its own.
• Cheese to the edge, sauce on top, in stripes, usually after the bake or in the final minutes.
• Often twice-baked: many shops par-bake the crust, then finish to order — that's how the bottom stays shatter-crisp under toppings.

The fakes skip the fermentation and the brick cheese, bake a same-day focaccia in a nonstick pan, and charge you the real price. The tell is the edge: pale, soft, or rimmed with bare crust means the shop bought the trend, not the technique.

The boom: how a regional square went national

Detroit style stayed a local secret for 60 years. Then came the 2010s wave of Detroit alumni opening shops on the coasts, a string of national pizza awards won with Detroit squares, and the pandemic takeout era — where Detroit style had a structural advantage: it survives the box. A Neapolitan is dead in 10 minutes; a Detroit square is still crisp after a 20-minute drive and reheats in a skillet almost better than fresh.

By 2021 the biggest chain in the country launched its own "Detroit-style" — the surest sign a trend has fully cashed out — and independents kept multiplying anyway, because the ceiling on quality is so much higher than the chain version. In 2026, Detroit style is no longer a trend; it's a permanent fourth seat at the American pizza table.

How to order it like you've been to Michigan

Order the corner pieces — an 8-square pie has four, they have two frico walls each, and regulars claim them first. The classic build is pepperoni under the cheese (old Detroit habit: the cup-and-char pepperoni crisps against the crust) with red-top sauce striped over. Eat it fresh but don't panic about speed; unlike the 10-minute-lifespan styles, a Detroit square gives you a forgiving half hour.

And reheat leftovers in a dry skillet, medium heat, lid off — five minutes and the bottom re-crisps to nearly day-one condition. The microwave is a war crime against frico.

The square deal

Here's the honest summary of why Detroit won the decade: it delivers what every other style promises. Thick, but light — the fermentation guarantees it. Crispy, but not dry — the oil-and-steel fry guarantees it. Cheesy to the literal edge — the frico guarantees it. And it costs slice-shop money, not deep-dish money, per square, as the price table in the pillar pizza guide shows.

New York gave America the slice, and Chicago gave it a casserole with confidence. Detroit gave it the corner piece — and once you've had one, you'll understand why the line starts at the pan's edge and works inward.
