There is a difference, even if just a small one (or more than that depending on who you ask). Originally, it is said that eggs Florentine was made much the same way as eggs Benedict, with a half of an English muffin, topped with steamed spinach instead of bacon, then a poached egg covered with mornay sauce (cheese sauce).However, some people believe that the two dishes are the same except for the addition of steamed spinach.
