Which McDonald’s sandwich is served with just half a slice of American cheese instead of a full slice?
Big Mac
McChicken
Filet-O-Fish
Cheeseburger
Fact: The Filet-O-Fish is the only standard McDonald’s sandwich traditionally made with half a slice of American cheese. The sandwich was introduced in 1962 by Cincinnati franchise owner Lou Groen, who created it to appeal to Catholic customers looking for a meatless option on Fridays during Lent. McDonald’s found that a full slice of cheese overwhelmed the mild flavor of the fish, so the recipe was adjusted to use only half a slice—a practice that has remained part of the sandwich’s iconic and signature preparation for decades.
Correct Answer: Filet-O-Fish
