Grandma pizza is attributed to which New York region? It is attributed to Long Island.

Grandma pizza is a thin, rectangular style associated with Long Island, New York. It is traditionally baked in a sheet pan and cut into small squares, giving it a home-kitchen character rather than the airy, thick crust commonly associated with Sicilian pizza.

The style grew from Italian-American home cooking in the early 20th century. Immigrants from southern Italy adapted pizza to ordinary American ovens and pans, using simple ingredients. Its name evokes the first-generation cooks who prepared these pies at home, without a specialized commercial pizza oven.

Long Island pizzerias helped popularize the term beyond family kitchens. Around 1994, Umberto Corteo introduced a “Sicilian Grandma” pizza at his Long Island restaurants. Despite the name, grandma pizza is usually thinner than classic Sicilian pizza. The cheese is commonly placed before the tomato sauce, another feature that can distinguish it from more familiar pizza styles.
