Cincinnati chili is a Mediterranean-spiced meat sauce used as a topping for spaghetti or hot dogs ("coneys"); both dishes were developed by immigrant restaurateurs in the 1920s. Its name evokes comparison to chili con carne, but the two are dissimilar in consistency, flavor, and serving method; Cincinnati chili more closely resembles Greek pasta sauces and spiced-meat hot dog topping sauces seen in other parts of the United States.

Spaghetti is a long, thin, solid, cylindrical pasta. It is a staple food of traditional Italian cuisine. Like other pasta, spaghetti is made of milled wheat, water, and sometimes enriched with vitamins and minerals. Italian spaghetti is typically made from durum-wheat semolina. Usually the pasta is white because refined flour is used, but whole wheat flour may be added. Spaghettoni is a thicker form of spaghetti, while spaghettini is a thinner form. Capellini is a very thin spaghetti, while vermicelli refers to intermediate widths, varying between the United States and Italy.
