McMuffin is a family of breakfast sandwiches sold by the international fast food restaurant chain McDonald's. The Egg McMuffin is the signature sandwich, which was invented in 1972 by Herb Peterson to resemble eggs Benedict, a traditional American breakfast dish with English muffins, ham, eggs and hollandaise sauce.

Product description

In the US and Canada the standard McMuffin consists of a slice of Canadian bacon, a griddle-fried egg, and a slice of American cheese on a toasted and buttered English muffin. The round shape of the egg is made by cooking it in a white plastic ring surrounded by an outer metal structure.


The sandwich was invented in 1972. Former McDonald's President Ray Kroc wrote that Herb Peterson and his assistant, Donald Greadel, the operator of a Santa Barbara, California franchise, asked Kroc to look at something, without giving details because it was:

... a crazy idea — a breakfast sandwich. It consisted of an egg that had been formed in a Teflon circle with the yolk broken, and was dressed with a slice of cheese and a slice of grilled ham. It was served open-faced on a toasted and buttered English muffin. The advent of the Egg McMuffin opened up a whole new area of potential business for McDonald's, the breakfast trade.

The first McDonald's corporate-authorized Egg McMuffin was served at the Belleville, New Jersey, McDonald's in 1972.
