Traditional Italian pizza virtually always has thin crust
Though it’s a widely known fact that pizza is a dish that originated in Italy, American cooks have played around with the formula so much over the years that most of the pizzas ordered on this side of the Atlantic in any given day actually bear little resemblance to the pizza eaten in Italy. Most of the disparity is due to the crust, which on authentic Italian pizzas is virtually always thin. It goes without saying that Chicago-style deep dish is an entirely American variation on an Italian dish, but as it turns out, the same is true for most of the pizzas served by big chains like Little Caesars, Pizza Hut, Papa Johns, or Dominoes. If you go to an authentic Italian restaurant, either in the United States or on a vacation in Italy, expect thinner crusts.
