Italian-American cuisine is a fusion of traditional Italian cooking and American flavors, developed by Italian immigrants in the late 19th and early 20th centuries. It features popular dishes like spaghetti and meatballs, pizza, and lasagna, often adapted to suit local tastes and available ingredients. This cuisine emphasizes hearty portions and bold flavors, with an emphasis on tomato-based sauces, cheeses, and various meats. While it retains some elements of authentic Italian cuisine, such as the use of fresh herbs and olive oil, it has evolved into a distinct culinary style enjoyed across the United States.
