A Field Review: Chicago Deep-Dish Pizza

ByLori

What it is, and why it is not what you picture

Chicago deep-dish is the closest the city has to a defense of its own food. It is not thin. It is not folded. It is a deep, cast-iron pan of dough buttered on the sides like a pie crust, packed with a thick layer of low-moisture mozzarella, loaded with toppings, and then topped with tomato sauce — the reverse of the Italy you may expect. The sauce goes last so it does not turn the cheese to a rubbery slab; the cheese sits close to the bottom where it can brown. Cut it with a table knife, not a hand; you will use the back of a fork for the edges.

The origin

The standard telling is Ike Sewell and Pizzeria Uno in 1943, on the Lower East Side of Chicago. As Uno tells it, Sewell combined “authentic” Italian recipes with “impressive quantities of the finest meats, spices, vegetables and cheeses” to make pizza into a hearty meal, and when the place could not fit the crowd he opened Pizzeria Due on the corner. The restaurant still holds that lineage at 29 E. Ohio Street. The claim, like all origin claims, is a story; treat it as tradition with the confidence the city itself does.

The two houses people argue about

Pizzeria Uno

The original by any telling: cast-iron pan, 1940s recipes, sauce on top, and a buttery crust baked at the corner of the river. It is the reference point the whole argument orbits.

Lou Malnati’s

Open since March 17, 1971 in Lincolnwood, a northern suburb, and run by the Malnati family across generations after Lou himself died of cancer in 1978. Their pitch is craft and supply: a generation-old flaky butter crust, California vine-ripened tomatoes they select at harvest, and mozzarella from a single small Wisconsin dairy they have worked with for decades. They are the name locals are most likely to defend on the record.

The verdict

Deep-dish is an acquired taste in the narrow sense that it is not designed to be light. It is a dense, savory, butter-forward meal served by the slice or the half, meant to feed, not to snack. Its virtues are structural: the cast-iron pan and the buttered sides give a crust that is crisp where a thin crust would be, and the sauce-on-top layering keeps the cheese from going rubbery. Its vices are that it is heavy, slow to eat, and not the pizza you reach for when you want a quick thing. Pizzeria Uno is the thing to order if you want the origin; Lou Malnati’s if you want the version a Chicagoan is most likely to vouch for.
