About Marconi

Based in
Des Plaines, Illinois
Founded
1898
Known for
Chicago-style giardiniera

In 1898 Vincent Formusa, an Italian immigrant newly settled in Chicago, began importing Sicilian foods. Vincent later widened the business with his son Peter, adding pickled vegetables, olive and vegetable oils, tomatoes and pasta. The family business, V. Formusa Co. and Marconi Foods, is now based in Des Plaines, Illinois, with the fourth generation in its leadership.

Marconi calls its giardiniera a staple across Chicagoland and the cornerstone of the Italian beef sandwich. Chicago-style giardiniera is small pieces of vegetables pickled and then kept in oil, and since it has no true recipe, each maker sets its own heat and blend.

Pile giardiniera on beef, sausage or a muffuletta-style sandwich, spoon it onto pizza, or toss pickled peppers into pasta and pan sauces.

It goes on an Italian beef sandwich or a slice of pizza, or is eaten on its own as an antipasto, an Italian starter course.
