Every year on February 9, people around the world celebrate National Pizza Day, honoring one of the most beloved dishes globally. This day pays tribute to pizza, which originated in Italian cuisine, evolving from flatbread recipes in Naples during the late 1700s or early 1800s. Today’s pizza usually features a dough base topped with sauce, cheese, and a variety of ingredients, with the classic Neapolitan Margherita pizza highlighting tomatoes, mozzarella, and basil. In the United States, pizza became widely popular in the early 1900s, giving rise to unique styles like Chicago’s deep-dish pizza and the often-debated Hawaiian pizza. National Pizza Day is part of a larger set of food celebrations dedicated to different pizza types, such as National Cheese Pizza Day and National Pepperoni Pizza Day. The holiday gained extra attention starting in 2021, when Google celebrated pizza with a Doodle on December 6 to mark the recognition of the Neapolitan “Pizzaiuolo” craft as a UNESCO Intangible Cultural Heritage.
