Detroit-style pizza is a thick, rectangular pizza baked in a well-oiled blue steel pan, with cheese spread all the way to the edges where it caramelizes against the pan wall into a crunchy, almost-fried border. The tomato sauce goes on top of the cheese — not underneath it — usually added in streaks or pools after the cheese has set. The interior dough is soft, airy, and open-crumbed, more like focaccia than dense bread, which makes the pizza lighter than it looks. The result is a single slice with four distinct textures: a crunchy fried bottom, a caramelized cheese border on each side, a soft and open-crumbed interior, and bright acidic sauce sitting above it all.
The style was born in 1946 at Buddy's Rendezvous, a bar on the east side of Detroit, where a cook named Gus Guerra made the first rectangular pan pizza in the United States. The pan he used was a blue steel industrial tray — the kind used in Detroit's auto plants to catch oil and grease under assembly-line machinery. That industrial material turned out to be nearly perfect for pizza: it conducted heat evenly across the bottom and retained it at the high temperatures needed to fry and caramelize the cheese at the pan's edges. Detroit-style pizza is, in this sense, a byproduct of the automobile industry, in the same way that the city's music and architecture are products of the wealth and character of a particular place and time.
The blue steel pan is not a stylistic choice — it is the structural reason the pizza tastes the way it does. Blue steel is a carbon steel with a blue-gray color from the tempering process; it heats faster than stainless steel, distributes heat more evenly across the surface, and builds seasoning over time the way a cast-iron skillet does. The trays used at Buddy's in the 1940s were genuine industrial components, pulled from automotive suppliers. Those trays had steep sides, solid bottoms, and no nonstick coating — the cook had to oil them heavily before each bake, which set up the fried bottom crust that became the style's most distinctive quality.
The steep sides are the second critical element. Because the pan has walls rather than a low rim, the cheese can be pressed flush against the pan's interior edge. During the bake, as the oven temperature reaches around 500 degrees Fahrenheit, the cheese against the walls heats faster than the cheese in the center — and at that temperature, it moves through melting and into browning, then into what pizza cooks now call the frico crust: a lacy, bubbly, crackly layer of caramelized cheese fused to the pan wall. At Buddy's, the frico crust was so reliably produced that it became expected, then protected, then emulated. It is now one of the most imitated elements in American pizza, turning up at shops from Brooklyn to Portland that would not exist if Gus Guerra had used a different pan.

Not every thick square pizza is Detroit-style. Five elements need to be present for a pizza to genuinely fit the category.
The pan is the foundation — deep blue steel, well-seasoned and generously oiled before each use. The oil is not incidental; it creates the fried, crunchy bottom crust that is entirely different from the bready base of a Sicilian or standard pan pizza.
Wisconsin brick cheese is the traditional choice. It melts more evenly than mozzarella, with a mild, slightly nutty flavor and a fat content that produces the specific frico browning at the right oven temperature. Many modern Detroit pizzerias use a blend of brick and low-moisture mozzarella; brick cheese alone is now harder to source outside the Midwest.
Cheese to the edges is what creates the frico crust. The cheese must reach all four walls of the pan; if it stops short, there is no caramelization, no crunch, and the pizza reads as a standard pan pizza rather than a Detroit one.
Sauce on top is the most counterintuitive feature. The tomato sauce — typically seasoned simply with oregano and garlic — goes on after the cheese is placed, either before or after the final minutes of baking, depending on the shop. This keeps the sauce vivid and bright rather than cooked down into the cheese layer.
An airy, open interior distinguishes the crumb from denser styles. The dough is high-hydration with a long, cold ferment that produces large, irregular air pockets. Despite being thick, a proper Detroit slice is not heavy.
Two comparisons come up constantly, and both need untangling.
Detroit versus Sicilian: Sicilian-style pizza — the sfincione tradition from western Sicily, and the American sfincione-descended square — is the ancestor of the Detroit style. Both are square, both are thick, both are baked in oiled pans. But Sicilian pizza typically has the sauce applied to the dough before the cheese, produces a denser, breadier interior without the open crumb of a Detroit pie, and does not develop the steel-pan frico crust that is the Detroit style's signature. The cheese-to-edges caramelization and the reversed sauce position are the two differences that separate Detroit from its Sicilian predecessor. The connection is real — Gus Guerra's family had Sicilian roots, and sfincione almost certainly shaped his starting point in 1946 — but the resulting pizza is distinct enough to be its own category.
Detroit versus Chicago deep dish: The comparison is frequently made and rarely accurate. Chicago deep dish is baked in a tall, buttery pan with a crust that rises up the sides and has a texture closer to pastry than pizza bread. The cheese goes inside, the sauce goes on top, and the whole thing bakes for 30 to 45 minutes into something that many people eat with a fork. Detroit-style is thinner than deep dish, crisper, faster to eat, and closer to a traditional pizza eating experience. The two share the trait of having sauce on top, and that is roughly where the similarity ends. Calling them the same style because both are thick is like calling a cornbread muffin and a souffle the same dish because both are baked in a vessel.
Buddy's has expanded to around fifteen locations across the Detroit metro, but the original location on Conant Ave at 6 Mile Rd — where Gus Guerra made the first pan pizza in 1946 — is where the story began. The room has the feel of a neighborhood bar that became a landmark: dark wood, photographs, booths, and a crowd of regulars who have been ordering the same corner square for decades. The cheese pull and frico crust at the original Buddy's remain a reliable benchmark.
Michigan & Trumbull is named for the historic Detroit intersection where Tiger Stadium stood for 87 years. The restaurant operates at the Shed in the Corktown neighborhood and landed on Food & Wine's Best Pizzas in America list for 2026. Local critics frequently name it the finest single Detroit-style pizza currently being made in the city — the dough is carefully stretched and rested, and the frico crust is exacting.
Loui's Pizza in Hazel Park, a suburb northeast of Detroit, ranked first in a Metro Times survey of 25 Detroit-style pies across Wayne, Oakland, and Macomb counties. It has been making pan pizza since the 1970s, and its consistency over fifty-plus years earns it the kind of reputation that newer shops still measure themselves against.
Sgt. Pepperoni's, operating inside the Garden Bowl bowling alley at 4120 Woodward Ave, is the right choice for a late-night pizza in an only-in-Detroit setting. Order a square at the counter, bowl a few frames under neon lights, and discover that an excellent pizza and a genuinely analog entertainment venue are a perfect pairing.

Detroit-style went national more quietly than New York or Chicago's exports did, but it arrived. Restaurants in New York, Washington D.C., Los Angeles, and dozens of smaller cities now make Detroit-style pies as a primary offering. The mass-market version came from an unexpected source: Little Caesars, the Detroit-born chain, introduced its DEEP!DEEP! Dish Pizza as a commercial interpretation of the steel-pan style and brought the concept of a square pan pizza with caramelized cheese edges to millions of people who had never encountered the original.
The more important spread happened through individual pizza cooks who trained in Detroit and then opened their own shops elsewhere, and through the broader American pizza community's growing interest in regional styles beyond New York and Chicago. Detroit-style now has an identity clear enough that pizza writers compare new shops to it the way they once compared everything to New York thin-crust.
When ordering outside Detroit, look for mentions of a 'steel pan,' a 'frico crust,' or 'cheese to the edge' — those phrases signal that the shop has studied the original. A thick square pizza cut into portions and labeled 'Detroit-style' without those specific features is likely a marketing choice rather than a technique choice.
Is Detroit-style the same as Sicilian? Related, but no. Sicilian pizza has sauce under the cheese and bakes to a denser, breadier texture without the steel-pan frico crust that defines the Detroit style. The two are linked by ancestry — Sicilian immigrants in Michigan shaped the original Buddy's recipe — but they produce distinctly different results. Ordering one and expecting the other will leave you surprised.
What makes brick cheese essential? Wisconsin brick cheese melts at a lower temperature than mozzarella and has a fat composition that produces the specific caramelization the frico crust requires. Without it, or without a blend that includes it, the cheese edges brown but do not develop the same crunchy, lacy texture. Brick cheese is mild enough that it does not compete with the tomato sauce — it provides richness and structure rather than a strong dairy flavor.
When should you visit? Buddy's and Michigan & Trumbull operate year-round with no meaningful seasonal variation. Detroit summers — June through August — make it easiest to combine the pizza tour with a walk through Corktown and a visit to the Motown Museum, which is about ten minutes north of the original Buddy's on Conant. The city's food scene has expanded considerably since 2015, and a pizza tour now fits naturally into a broader Detroit visit with much more on offer than the pizza alone.
