Hailed as one of the best things to ever come out of Chicago, traditional deep dish pizza is in a class all its own. Although it contains many of the same ingredients as a classic pizza, Chicago deep dish pizza is assembled in reverse. Built upon a sturdy base of dough with high sides, the toppings of cheese, Italian sausage, peppers, and onions are layered on the bottom—with an ample covering of zesty tomato sauce on top! Pizza Pro’s recipe for this Chicago staple tastes delicious baked in an Ooni pizza oven and cast iron skillet.
