The word “crostone” is derived from the Italian “crostino,” which means “little crusts” (of bread). The bread can either be toasted or grilled, and can be topped with a variety of toppings like meats, cheeses, and veggies. This dish is usually served as an appetizer or as a snacks.
Crostone is just simply the larger form of crostino. Instead of using small-bite sized pieces, crostone uses bigger pieces of bread as a vehicle for the toppings.
