Which fast food chain pioneered the breakfast sandwich with the Egg McMuffin? McDonald’s pioneered it.
The Egg McMuffin was created for McDonald’s in 1972 by Herb Peterson, a franchise operator and former McDonald’s advertising executive. Peterson wanted a portable breakfast inspired by eggs Benedict, but hollandaise sauce was impractical for fast-food service. His solution combined a toasted English muffin, Canadian bacon, a cooked egg, and American cheese.
The sandwich was first developed and sold at a McDonald’s restaurant in Goleta, California, near Santa Barbara. Peterson cooked the egg in a ring mold to give it the distinctive round shape that fits the muffin. The product helped McDonald’s establish breakfast as a major part of the fast-food day, rather than limiting the chain’s business to lunch and dinner.
People sometimes credit Ray Kroc because he helped approve and expand the product nationally, but he did not invent it. Peterson and his assistant Donald Greadel developed the sandwich, while McDonald’s turned their franchise experiment into a corporate menu staple. The “McMuffin” name also refers to a broader family of McDonald’s breakfast sandwiches, not only the original egg version.
