A good Chicago-style pizza is defined by its deep-dish crust, which is made from a buttery, flaky dough and is thick enough to hold a generous amount of toppings. The sauce should be centered on top of the cheese and not hidden underneath it, and the cheese should be a combination of mozzarella and a second cheese, such as provolone or cheddar. The toppings should be high-quality and plentiful, with sausage and pepperoni being popular choices, but options like spinach, mushrooms, or roasted red peppers are also widely used. A good Chicago-style pizza is a true masterpiece of flavor and texture, with a crispy crust, gooey cheese, and a perfect balance of savory, tangy, and sweet flavors from the sauce and toppings.
