St. Louis style pizza is the most polarizing regional pizza in America. People either love it passionately or find it deeply confusing. The crust is cracker-thin and crispy — no yeast, no chew. The cheese is Provel, a processed blend that tastes nothing like mozzarella. And it’s cut into squares, not slices. Once you get past the shock, you realize this pizza is actually brilliant.
What Is St. Louis Style Pizza?
St. Louis style pizza developed in the mid-20th century as a distinctly Midwestern take on pizza. It’s defined by three things: an unleavened cracker crust (made without yeast), Provel cheese, and a “party cut” — squares instead of wedges. It’s thinner than any other pizza style, sturdy enough to pick up, and built to eat in large quantities at a social gathering.
The Crust: No Yeast, All Crunch
The St. Louis crust uses no yeast whatsoever. It’s made from flour, water, oil, salt, and baking powder — essentially a flatbread or cracker dough. Because there’s no yeast fermentation, there’s no rise, no chew, and no air bubbles. The result is a perfectly flat, uniformly thin crust that bakes up completely crispy all the way through.
This crust is rolled out thin (about ⅛ inch) and baked at 450°F for 10-12 minutes. It snaps when you break it. That’s exactly what you want. The crunch is the whole point.
Provel: The Cheese You’ve Never Had
Provel is a processed cheese blend of provolone, Swiss, and white cheddar — invented specifically for St. Louis pizza in the 1940s. It melts at a lower temperature than mozzarella, creating a smooth, creamy layer that doesn’t stretch or pull when you bite into it. It also has a mild, slightly smoky, buttery flavor that’s completely different from mozzarella.
Provel is hard to find outside St. Louis, but you can approximate it by blending equal parts shredded provolone, white cheddar, and Swiss cheese. It won’t be identical, but it’ll get you close enough to understand what the fuss is about.
The Party Cut: Squares Only
St. Louis pizza is always cut into squares (or rectangles), never wedges. This is called a “party cut” or “tavern cut” — it originated in St. Louis taverns where pizza was served as a bar snack and cut into small squares so people could grab pieces while drinking without needing a plate. The square cut also means every piece has roughly the same ratio of crust to topping, which is hard to achieve with wedge cuts on a round pizza.
How to Make St. Louis Style at Home
This is one of the easiest pizza styles to make at home because there’s no dough rising or proofing involved. Mix your cracker dough, let it rest 10 minutes, roll it as thin as you can, and bake. The hardest part is sourcing Provel — if you can find it online, order it. If not, the provolone-cheddar-Swiss blend works well.
Classic St. Louis toppings lean traditional: pepperoni, sausage, mushroom, green pepper, onion. Don’t overthink it. The magic of St. Louis pizza isn’t in creative toppings — it’s in the texture contrast between that snappy cracker crust and the smooth, creamy Provel. Make it once and you’ll understand why an entire city is devoted to it.
