Chef Boyardee, formerly Chef Boy-Ar-Dee, is a brand of canned pasta products sold internationally by ConAgra Foods. The company was founded by Italian immigrant Ettore "Hector" Boiardi in Cleveland, Ohio, U.S.A., in 1928.
In 1924, Boiardi opened Il Giardino d'Italia restaurant at East 9th Street and Woodland Avenue in Cleveland, Ohio.
The idea for Chef Boyardee came about when restaurant customers began asking Boiardi for his recipes. He opened a factory in 1928, moving production to Milton, Pennsylvania, ten years later, where enough tomatoes and mushrooms could be grown. He decided to name his product "Boy-Ar-Dee" to help Americans pronounce his name.
