History

It might be a good idea to start talking about deep dish pizza by taking some time to acknowledge Pizzeria Uno’s founder, Ike Sewell, without whom this day wouldn’t exist.

In fact, without him, the deep dish pizza wouldn’t exist–and that would be a very sad world.

Sewell is credited with creating the spectacular deep dish pizza in 1943 in Chicago, Illinois, USA.

This wonderfully tasty pizza, also known as Chicago-style pizza, is characterised by a superb buttery crust that can be as high as 3 inches tall along the edges, combined with generous amounts of flavoursome sauce, delectable toppings and cheese.

Once the idea for deep dish pizza caught on in Chicago, it was only a short time before it became a trademark of the city–and in doing so it became the exact opposite of its rival pie: thin crust pizza from New York.

How to celebrate

Grab a Deep Dish Pizza

On this day, get together with friends or family to visit your favourite pizza restaurant and enjoy a wonderful slice (or more) of cheesy goodness. But remember, unlike grabbing a slice of thin, New York pizza that takes about 10 minutes to bake, deep dish pizza is an exercise in patience. It might even be a good idea to order ahead because these pizzas are so thick that they can take up to an hour to bake in the oven! But don’t worry–most restaurants are happy to provide appetizers such as breadsticks, buffalo wings or garlic bread to keep hungry patrons happy, as well as soft drinks or beer. Just make sure not to get too filled up before the pizza comes.

FAQ

Did you know deep-dish pizza might have been inspired by an Italian Easter pie?

Rocco Palese, founder of Nancy’s Pizza, created stuffed pizza in 1971, drawing inspiration from his mother’s scarciedda—a savory Italian Easter pie filled with ricotta and meats.

Why is the sauce on top in a deep-dish pizza?

In deep-dish pizzas, the cheese and toppings are placed first, with the tomato sauce on top. This arrangement prevents the cheese from burning during the longer baking time required for the thick crust.

Is it true that deep-dish pizza is sometimes considered a casserole?

Some critics, especially fans of thin-crust pizza, argue that deep-dish pizza resembles a casserole more than a traditional pizza due to its thickness and layered structure.

How do Chicagoans feel about deep-dish pizza compared to other styles?

While deep-dish is iconic, many Chicago locals prefer tavern-style pizza, which has a thin, crispy crust cut into squares, viewing deep-dish as more of a tourist attraction.

Did you know there’s a debate about who invented deep-dish pizza?

While Pizzeria Uno’s founder Ike Sewell is often credited, some suggest that the original recipe came from the restaurant’s cook, Alice Mae Redmond, or manager Rudy Malnati Sr.

What’s the difference between deep-dish and stuffed pizza?

Stuffed pizza includes an extra thin layer of dough atop the cheese and toppings, beneath the sauce, creating a pie-like appearance, whereas deep-dish lacks this additional layer.

Is deep-dish pizza healthier than regular pizza?

Due to its thicker crust and higher cheese content, deep-dish pizza generally contains more calories and fat than regular pizza. However, it can still be enjoyed in moderation as part of a balanced diet.

Did you know deep-dish pizza has a unique baking method?

The crust is often pre-baked before adding toppings to ensure it remains crisp and doesn’t become soggy under the weight of the fillings.

How has deep-dish pizza influenced other regional styles?

Detroit-style pizza, with its rectangular shape and thick crust, was inspired by Chicago’s deep-dish but features its own unique characteristics, like a crispy, cheesy edge.

Did you know deep-dish pizza can be made with cornmeal?

Some recipes incorporate cornmeal into the dough to add texture and a subtle flavor to the crust.
