Deep Dish Pizza Day

Deep Dish Pizza Day History

Deep Dish Pizza Day celebrates the Chicago-styled deep crust pie. Deep-dish pizza differs from regular pizza in the way that it is baked. Using a high-edged pan, the crust thickens and deepens. This allows a multitude of toppings to be used including meats, vegetables, and cheeses. Finally, the deep-dish pie is topped with a tomato sauce and left to bake.

It is believed that deep-dish pizza was invented in 1943 at a pizzeria in Chicago called Pizzeria Uno. The founder Ike Sewell claimed it was his idea but others claim the idea was his pizza chef Rudy Malnati’s. Nonetheless, Deep Dish Pizza Day celebrates the popular baked dish and encourages everyone to enjoy a slice. This day is observed annually on April 5th.
