The Filet-O-Fish was created for Friday customers in a neighborhood with many members of which church? The answer is the Roman Catholic Church.

McDonald’s franchisee Lou Groen developed the sandwich in 1962 at his restaurant in Cincinnati’s Monfort Heights neighborhood, which had a predominantly Catholic population. Many Catholics traditionally abstained from eating meat on Fridays, causing hamburger sales to fall sharply at Groen’s restaurant.

Groen proposed a fish sandwich as a way to serve those customers. Ray Kroc agreed to test it against his own meatless alternative, the Hula Burger, which used grilled pineapple and cheese. The Filet-O-Fish won the trial decisively and was added to McDonald’s menus in 1963 before becoming nationally available in 1965.

The question refers to the community’s religious makeup, not to a particular Catholic denomination or a church building. Anglican, Greek Orthodox, and Lutheran customers may also eat fish on Fridays, but the historical origin story specifically identifies a predominantly Roman Catholic neighborhood and Catholic abstinence practices.
