#12: Egg McMuffin, 1972
Price: $0.63
With the Egg McMuffin, McDonald’s entered the breakfast market in a serious way. Featuring a real cracked egg, Canadian bacon, and English muffin, it felt surprisingly upscale. Its success transformed mornings into a new profit window and reshaped fast food permanently.

Still a cornerstone of the breakfast menu, the Egg McMuffin now costs around $4.00–$5.00. While competitors have expanded breakfast offerings dramatically, this original item remains influential, representing one of the most successful menu expansions in fast-food history.
