Italian-American cuisine was born from the sudden abundance of meat, cheese, and eggs.

In short: For impoverished Italian immigrants arriving in the United States, the move meant more than just a new home; it meant a radical culinary shift. While retaining the simple preparation of their homeland, they embraced a newfound prosperity, transforming peasant traditions into the rich, red-sauce staples we recognize today.

In the late 19th and early 20th centuries, Italian immigrants faced severe food insecurity, surviving on a sparse, mostly vegetarian diet of hard bread and soups. Meat was a luxury reserved only for rare celebrations. Upon arriving in the United States, these immigrants found higher wages, allowing them to afford ingredients that were previously inaccessible, such as meat, cheese, eggs, and olive oil. This reaction to abundance defined Italian-American cuisine, which heavily emphasizes these rich ingredients while maintaining the simple, efficient techniques of the Italian cucina povera, or 'cuisine of the poor'.

While Southern Italian traditions—specifically Neapolitan and Sicilian—form the base of this style, Northern Italian immigrants also left their mark. For instance, cheesemakers Paolo Sartori and Count Julio Bolognaisi leveraged Wisconsin's milk supply to produce Parmesan cheese. This regional fusion occurred as immigrants from different parts of Italy settled in the same neighborhoods and exchanged recipes. Over time, this cuisine became so ingrained in American culture that by the late 1990s, studies indicated that more than nine out of 10 consumers were familiar with Italian, Mexican, and Chinese cuisines.

The evolution of this food was also shaped by external forces. During Prohibition, from 1919 to 1933, many Italian-American wineries survived by producing sacramental wine or grape juice, effectively salvaging America's viticulture heritage. Meanwhile, the perception of Italian-American cooking has shifted; while once portrayed as a simplified version of authentic Italian food, it is now recognized as a distinct cultural expression. Today, there is a growing push toward producing more authentic dishes using native Italian techniques, even as American-influenced creations like carbonara—which may have emerged following the 1944 liberation of Rome—remain popular fixtures in the American diet.
