It isn't a casserole. Let's just get that out of the way immediately. If you’ve ever sat through a late-night comedy set where a New Yorker rants about how deep dish Chicago pizza is basically a "lasagna in a bread bowl," you’ve heard the cliché. It’s a tired joke. It's also factually incorrect.
True Chicago pizza is an engineering marvel.
When you walk into a place like Lou Malnati’s or Pizano’s, you aren’t just ordering dinner. You’re ordering a forty-five-minute commitment to a specific type of buttery, flaky crust that defies the laws of standard dough fermentation. Most people think "deep" means "thick dough." Actually, the dough is relatively thin. It’s the sides that are high. This creates a basin for an ungodly amount of mozzarella, followed by toppings, and finished with a crushed tomato sauce that looks like a chunky blanket.
Why the reverse order? Simple physics. If you put the cheese on top for a forty-minute bake, it would turn into a blackened, charred sheet of carbon. By burying the cheese under the sauce, it stays gooey, molten, and protected.
The Pizzeria Uno Origin Myth and the Real Players
History is messy. Most folks credit Ike Sewell and Ric Riccardo with inventing the style at Pizzeria Uno in 1943. That’s the official story. But if you talk to food historians like Peter Regas, who has spent years digging through dusty Chicago archives, the narrative shifts toward the kitchen staff—specifically Rudy Malnati Sr. and Alice May Redmond.
Alice May Redmond is a name you should know. She was a cook at Pizzeria Uno for years before she was headhunted by Gino’s East. She brought her dough recipe with her. That’s why the crust at Gino’s has that distinct, yellow, almost biscuit-like texture. Some people think there's cornmeal in there. There isn't. It’s actually a specific type of coloring or vegetable oil blend, but the legend of the "cornmeal crust" persists because humans love a good secret ingredient story.
The industry is tight-knit. It’s basically a family tree. Lou Malnati worked at Uno before opening his own spot in Lincolnwood in 1971. Rudy Malnati Jr. opened Pizano’s. These aren't just restaurants; they are legacies built on high-fat dough and proprietary sausage blends.
Why the Crust Is Actually a Biscuit
Standard New York pizza uses high-protein bread flour to get that "chew." You want gluten development. You want stretch.
Deep dish is the opposite.

You want "shortness." In baking, a short crust means the fat has coated the flour particles so thoroughly that gluten can't form long, elastic strands. This is why a Lou Malnati’s crust crumbles and flakes like a savory pie or a French galette. It’s heavy on the butter—or margarine, depending on the secret family recipe—and it's patted into a seasoned steel pan rather than being tossed.
It’s dense. It’s rich. It’s incredibly filling. One slice is usually enough to stop a grown adult in their tracks, yet we always order the large.
The Buttercrust Controversy
If you’re at Lou Malnati’s, you’ll see an option for "Buttercrust." It’s an extra buck or two. Do it. Honestly, it’s the only way to go. It adds a level of lamination to the dough that turns the edges into something resembling a savory croissant.
But here is a nuanced point: not all deep dish is created equal. You have two distinct sub-species:
- Traditional Deep Dish: This is the Uno/Malnati style. Single layer of dough, topped with cheese, then ingredients, then sauce.
- Stuffed Pizza: This is what you get at Giordano’s or Nancy’s. It’s even taller. There is a bottom crust, then cheese and fillings, then a second paper-thin layer of dough on top, and then the sauce.
Giordano’s was started by Italian immigrants Efren and Joseph Boglio in 1974. They used their mother’s recipe for "scarciedda," an Easter pie. Stuffed pizza is basically a structural upgrade. It allows for even more cheese because that second layer of dough acts like a lid, keeping the steam inside and turning the cheese into a literal lava pit. It’s decadent. Some purists hate it. They think it’s too much. They might be right, but try telling that to the crowds in the Loop on a Friday night.
The Sausage Patty: A Chicago Signature
When you order sausage on a deep dish Chicago pizza, don't expect crumbles.

In Chicago, the "patty" style is king. The pizzaiolo takes a massive hunk of raw, fennel-heavy Italian sausage and flattens it into a giant disc that covers the entire layer of cheese. One solid sheet of meat. This ensures that every single bite has a 1:1 ratio of sausage to cheese to crust. It also acts as a moisture barrier, preventing the fat from the sausage from soaking into the crust and making it soggy.
It’s smart engineering disguised as gluttony.
Where Most Tourists Get It Wrong
People go to the big chains and think they’ve seen the whole map. They haven’t. If you want to see the soul of the city, you look at the neighborhood spots.
- Burt’s Place: Located in Morton Grove. The late Burt Katz was a legend. He wore a captain’s hat and didn't take any crap. He pioneered the "caramelized crust"—where the cheese is pushed all the way to the edge of the pan so it burns slightly against the steel. It creates a black, crispy, salty ring of joy.
- Pequod’s Pizza: This is the current "it" spot. They use the Burt Katz method. The blackened edges look burnt. They aren't. It’s caramelized lactose and fats. It’s bitter and salty and perfect.
- The Art of Pizza: Often voted the best in the city by locals, it’s less about the "show" and more about a perfectly balanced sauce-to-cheese ratio.
The wait times are part of the ritual. You can’t rush this. If a place serves you deep dish in ten minutes, leave. It takes thirty-five minutes just to cook through that layer of raw sausage and melt the pound of mozzarella in the middle.
Is Deep Dish Actually for Locals?
There is a common myth that Chicagoans only eat thin-crust "tavern-style" pizza (square cut, cracker crust) and leave the deep dish for the tourists.
That’s a half-truth.
We eat tavern-style on a random Tuesday. We eat deep dish when someone is in town, for birthdays, or when we just want to feel something. It’s a "destination" meal. It’s heavy. It’s a commitment. You don't eat it before going for a jog. You eat it and then you sit on your couch for three hours questioning your life choices in the best way possible.
Health and Logistics
Let’s be real: this isn't health food. A single slice of stuffed pizza can clock in at 600 to 900 calories. It’s a sodium bomb. But the quality of ingredients matters. Real Chicago spots use Wisconsin whole-milk mozzarella. They use tomatoes grown in California's Central Valley or imported from Italy.
If you're trying to take one home, don't use a microwave. You’ll ruin it. The crust will turn into rubber. Put it in an oven at 375°F (190°C) on a baking sheet for 15 minutes. It’ll crisp back up.
How to Order Like a Pro
If you want the authentic experience, don't overcomplicate the toppings. The more veggies you add (onions, green peppers, mushrooms), the more water they release during the long bake. This can lead to a "soupy" pizza.
Keep it simple. Sausage and pepperoni. Or just the sausage patty. The "Chicago Classic" at Malnati’s—sausage, extra cheese, and buttercrust—is the gold standard for a reason.
Also, ask for it "well done" if you like that caramelized cheese edge. Most places will leave it in for an extra three or four minutes to get that Maillard reaction going on the crust.
Actionable Steps for Your Next Slice
If you’re planning a trip or just a local looking to branch out, here is how you handle the deep dish experience without failing:
- Call Ahead: Many places let you "pre-order" your pizza while you’re on the way or waiting for a table. Since the bake time is 45 minutes, this can save your evening.
- The Knife and Fork Rule: Don't try to pick it up immediately. It's too heavy. Use the tools. After about five minutes, the cheese sets enough that you might be able to go hand-to-mouth, but start with the cutlery.
- Check the Bottom: A good deep dish should have a fried-bottom texture. It shouldn't be doughy or wet. If it is, the oven temp was too low or the pan wasn't seasoned.
- Explore the Suburbs: Don't be afraid to leave downtown. Some of the best iterations of this style are in the strip malls of Des Plaines or the quiet corners of Morton Grove.
- The "Tavern" Pivot: If you’re with a group, order one deep dish and one tavern-style thin crust. It provides the perfect texture contrast and prevents "cheese fatigue."
The world of Chicago pizza is deeper than a steel pan. It's a history of immigration, kitchen secrets, and a stubborn refusal to make a "normal" pizza. Respect the process, wait for the bake, and always get the buttercrust.
