History of National Deep Dish Pizza Day

The origins of National Deep Dish Pizza Day are intimately entwined with the history of the deep dish pizza itself. This distinctive recipe was brought to life in the heart of Chicago, Illinois, by Ike Sewell, the proprietor of the renowned Pizzeria Uno, in 1943. Sewell wanted to redefine the pizza experience by creating a hearty, satisfying meal as opposed to the relatively thinner pizzas that were standard fare during that time.

The end product of Sewell’s vision was a tall-edged pizza pie abundant in cheese and topped with thick, chunky tomato sauce - the now-famous Chicago-style deep dish pizza. This innovation immediately won over the people of Chicago, a love affair that has spanned over seven decades.

This inventive culinary creation sparked a revolution within the pizza industry, leading to numerous pizzerias creating their own versions of the deep dish, some even daring to experiment with different kinds of fillings, cheese, and sauce.

National Deep Dish Pizza Day, revered as a day to appreciate this popular form of pizza, seems to have cropped up in the past ten years or so. The day has likely come to be as a marketing strategy employed by restaurants. Regardless, it serves as a wonderful excuse for pizza enthusiasts nationwide to enjoy a slice or more of this thick and cheesy delight.
