We’d wager that pepperoni is still America’s number-one, most-popular pizza topping. This singular topping even graces the pizza emoji! It makes sense if you really consider everything that is good about pepperoni: The salty and slightly spicy taste holds its own against waves of melty, gooey cheese and gets ever-so-slightly crisped in the hot oven in such a crave-worthy way that no one can resist pulling them straight from the smoldering hot pizza and dropping them directly into their mouths.

A combination of tomato sauce, cheese, ham, and pineapple that is as beloved as it is despised still makes our list of iconic pizzas. Hawaiian pizza was reportedly invented in Canada, not the American islands it is named for. Like BBQ chicken pizza, those who love it cite the sweet and savory combination as the biggest draw to this popular pizza.
