Chicago Deep-Dish Pizza

Read it from the bottom up: crust, cheese, sausage, tomato. The order is the whole argument. AI-generated illustration.

It is not a thick pizza. It is a pizza assembled in reverse, and every layer is where it is because of how long the thing has to sit in the oven.

Nobody can hand you a recipe for this from a document out of copyright, because the dish is younger than the public domain and the quantities below were worked out for this page. What there is instead is a very good paper chase. Peter Regas spent twelve years in the archives on it and laid the findings out for the Culinary Historians of Chicago in May 2021: a Chicago liquor licence application of November 1943 naming who actually owned the place, a Chicago Sun article of December 1943 describing it days after it opened, the 1944 partnership agreement, the run of licence applications for the address from 1939 to 1954, and photographs from the 1940s and 1950s showing a pizza noticeably thinner than what the city sells now. The address is 29 East Ohio Street and the restaurant opened in December 1943 as The Pizzeria, later Pizzeria Uno. A basement tavern called The Pelican had been a pizzeria at the same address until its owners closed up in November 1942, which is a detail worth sitting with before anyone says the building invented pizza in 1943.

From there the claims diverge and this page is not going to pick one. Uno's own website says the story begins in 1943 when Ike Sewell developed deep-dish pizza. Tim Samuelson, Chicago's cultural historian, told WTTW in July 2024 that there is no debate and that Ric Riccardo was the man behind opening The Pizzeria, with Sewell arriving slightly after; writing in the American Historical Association's Perspectives on History in November 2018, Elizabeth Elliott Poorman quoted him more bluntly still — Riccardo is deep-dish's father, period. Regas's reading of the documents agrees that Sewell very likely held no stake at the December 1943 opening, since it was his wife Florence who signed the 1944 agreement, and it also finds that Adolpho "Rudy" Malnati Sr., whose family has long been credited by its own account, was the pizzeria's third manager rather than its first. Alice Mae Redmond, a cook from Mississippi hired in the mid to late 1940s, is credited with reworking the dough into something closer to what is baked today. And the oldest first-person account is the one that reaches furthest back: a syndicated food page in the Forsyth County News of 17 June 1987, found in Georgia's newspaper archive, quotes Sewell himself saying that before he and Riccardo opened, pizza was not a meal, it was more of an appetizer, and that nobody except GIs who had been in Italy even knew what the word meant. Four names, one address, and no document that settles it.

Why this version works

The pan fries the crust. Two tablespoons of oil in a steel pan is not greasing, it is a shallow fry. The dough sits in it for thirty-five minutes at 425°F and comes out with a crisp, faintly blistered underside and a wall that holds its own weight. A non-stick pan, a glass dish or a springform will all give you a pale, steamed base instead.

The sausage goes in raw, as a sheet. A layer of raw bulk sausage pressed flat over the cheese renders into it and seasons the whole pizza from the inside. Pre-cooked crumbles give you dry pellets and no fat in the right place. Because the sausage is raw, the bake time is set by the meat and not by the crust, which is why the cheese had to be protected in the first place.

The tomato is barely cooked and goes on last. Whole peeled tomatoes drained and crushed by hand, with nothing simmered into them, finish cooking in the pan and keep their sharpness against all that fat. Put a long-simmered sauce on instead and you get something sweet and flat; put the tomato underneath the cheese and you get a wet crust and a scorched top.

Cheese on the bottom, and this is the load-bearing decision. Sliced mozzarella laid straight onto the dough does two jobs. It seals the crust against the water in the tomato, so the base stays crisp under half an inch of sauce, and it keeps the cheese away from the oven's direct heat, so it melts rather than browning to leather. The 1987 page describes the same order from the Chicago end: mozzarella first, thick-sliced or hand-shredded, then a more than ample portion of mildly seasoned sausage, then tomatoes lightly stewed and crushed by hand, then Parmesan and herbs.

Ingredient notes

Cheese: a pound of low-moisture whole-milk mozzarella, cut into slices about a quarter inch thick rather than grated. Slices lie flat and overlap into a seal; shreds leave gaps for the tomato to find. Fresh mozzarella is the wrong cheese here and will flood the pan.

Sausage: a pound of bulk Italian sausage, mild, fennel-forward, and definitely not lean. If you can only get links, slit the casings and use the meat. Chicago will sell you this pizza with the sausage as a single solid patty edge to edge, which is worth doing once.

Fat in the dough: olive oil and melted butter together. The fat is what shortens the crumb and what lets you press the dough up a two-inch wall without it springing back. It also means this dough does not need much gluten development — a short knead is right and a long one makes it tough.

Flour and cornmeal: plain all-purpose flour, not bread flour. This crust is supposed to be short and tender rather than chewy, closer to a biscuit than to a Neapolitan base, and high-protein flour fights that. The cornmeal is for texture and for the faint grit along the bottom that tells you which pizza you are eating.

Step by step

  1. Mix and rise. Stir the flour, cornmeal, yeast, salt and sugar together. Add the warm water, olive oil and melted butter and mix to a shaggy dough, then knead 4 to 5 minutes only, until smooth. Cover and leave 1 hour, until doubled.
  2. Press the pan. Pour 2 tablespoons of oil into a 12-inch round steel pan 2 inches deep and spread it up the sides. Press the dough into the pan and work it up the walls to the rim with your fingertips. If it springs back, wait 10 minutes and press again. Rest it 15 minutes.
  3. Crush the tomatoes. Drain the canned tomatoes well and crush them by hand into a bowl. Stir in the grated garlic, oregano, salt and olive oil. Do not cook this.
  4. Line it with cheese. Heat the oven to 425°F. Lay the mozzarella slices over the base and a little way up the walls, overlapping them so no dough shows through.

  5. Sausage, then tomato. Break the raw sausage over the cheese and press it flat into an even sheet. Spoon the crushed tomato over the sausage and level it. Scatter the Parmesan and a pinch more oregano on top.
  6. Bake and rest. Bake 30 to 35 minutes, until the wall of crust is deep gold and pulls away from the pan and the tomato has darkened at the edges. Rest it 10 minutes in the pan before cutting, or the whole thing slides out of its own wedge.
If the base came out pale and damp, the pan was not steel or the oven was not up to temperature before the pizza went in — run it 8 minutes on the floor of a 450°F oven and it will crisp. If tomato ran under the cheese and soaked the crust, the slices left gaps: next time overlap them and take them an inch up the wall. If the wall of crust slumped while it baked, the dough was pressed too thin at the top edge, so keep a visible lip when you press.

Storage and make-ahead

Leftovers keep 4 days refrigerated. Reheat cut wedges in a dry skillet over medium with a lid on for 6 to 8 minutes — the base re-crisps and the cheese loosens, which no oven and certainly no microwave will do together.

The whole baked pizza freezes for 2 months. Cool it completely in the pan, freeze it solid, then wrap it. Reheat from frozen, covered with foil, at 350°F for 35 minutes and uncovered for 10 more.

What to serve with it

Something bitter and cold on the side, because the pizza brings all the fat the table needs: escarole or romaine with lemon and anchovy, or a plain plate of pickled peppers.

For drinking, a lager or a sharp red with acid to spare. Sweet drinks flatten it.

Chicago Deep-Dish Pizza

A short, oily dough pressed up the walls of a steel pan, lined with sliced mozzarella, filled with sausage and covered with barely cooked tomato — built upside down so that half an hour in the oven does not burn the cheese.

Questions readers ask

Can I make it ahead?

Make the dough a day ahead and let it rise slowly in the fridge; it presses better cold and tastes better for the long ferment. Crush the tomato the same day you bake, since it sheds water once salted. The assembled, unbaked pizza should not sit — the raw sausage weeps into the cheese and the base goes grey.

Do I need a special pan?

You need steel, round, twelve inches across and two inches deep. A cake tin that deep will do, and so will a cast iron skillet of the same size, which gives an even better base and a shorter wall. What will not work is anything non-stick, glass or ceramic; those do not conduct fast enough to fry the bottom, and the crust steams instead.

So who actually invented deep-dish pizza?

No document says. The restaurant at 29 East Ohio Street opened in December 1943 and that much is on paper. After that: Uno's corporate site credits Ike Sewell; Chicago's cultural historian Tim Samuelson credits Ric Riccardo and calls it settled; Peter Regas's archival work finds Sewell had no ownership stake at the opening and that Rudy Malnati Sr. was the third manager rather than the first; and Alice Mae Redmond, hired later in the decade, is credited with the dough the city actually eats. Anybody who tells you it is decided is quoting a marketing department.

Why is there no standard for what pizza has to contain?

Because the federal government reserved the space and never filled it. Title 9 of the Code of Federal Regulations groups its definitions and standards of identity under headings, and the heading that covers meat snacks, hors d'oeuvres, pizza and specialty items opens at section 319.600 — which reads, in full, [Reserved]. Frankfurters get four hundred words of composition rules. Pizza gets an empty slot.
