Chicago Deep-Dish Pizza

Chicago deep-dish pizza is built in a deep round pan, its thick buttery crust pressed up the sides like a pie shell, cheese laid down first and a chunky tomato sauce spooned over the top rather than underneath. It was invented at Pizzeria Uno in Chicago in 1943, deliberately reversing the usual pizza order, and the city has kept it as a dish distinct enough that some locals refuse to call it pizza at all.

What it really is

An oiled, buttery dough presses into a deep steel pan and up its sides, giving the finished pizza real height rather than the thin, flat base most pizza is known for. Sliced mozzarella lines the base directly on the dough, then a thick, mostly uncooked tomato sauce — often just crushed tomatoes with basil and garlic — spoons over the top in place of the usual sauce-then-cheese order, since baking it the ordinary way would leave the middle undercooked. Sausage, when it's included, goes in as a full layer rather than scattered toppings. The whole thing bakes long enough for the crust to turn golden and crisp while the deep filling sets.

The reversed layering is the defining feature, not a stylistic flourish. Cheese sits closest to the crust specifically so the sauce on top can cook down without making the base soggy — building it the standard way changes the texture, not just the look.

How it's served

• Cut into thick squares, a knife and fork rather than eaten by hand.
• Straight from the pan it baked in, still visibly deep at the cut edge.
• As a full meal for one, rarely shared slice by slice the way thin-crust pizza is.

How to write it on the menu

• Flag the wheat in the crust and the dairy in the cheese.
• Say if sausage is a standard layer or an optional add, since a plain cheese version is common and naturally vegetarian.
• Note the wait time if it's baked to order — the depth means it genuinely takes longer than a thin-crust pizza.
