The horseshoe is an open-faced sandwich originating in Springfield, Illinois, United States. It consists of thick-sliced toasted bread (often Texas toast), a hamburger patty, French fries, and a "secret" cheese sauce. Sometimes ham or some other meat is substituted for the hamburger, and sometimes more than one type of meat is used. The French fries can also be replaced with tater tots, or other forms of fried potatoes.
A smaller portion, with one slice of bread and one serving of meat, is called a pony shoe.
Ross' Restaurant in Bettendorf, Iowa is known for a similar dish called the Magic Mountain. Instead of a hamburger patty, the sandwich contains steamed loose-meat. It has been enjoyed by politicians and celebrities including Barack Obama and Bette Midler.
The sandwich was created in the late 1920s by chef Joe Schweska at the Leland Hotel in Springfield, Illinois located on the corner of Sixth and Capitol (now an office building). The Leland Hotel, the leading hotel of Springfield, was built in 1867, and has housed hundreds of prominent Americans. The structure is five stories high and contained 235 rooms.
In the 2015 Thomas' Breakfast Battle, hosted by Thomas' Breads, Mike Murphy won a $25,000 prize for his breakfast horseshoe. The contest featured chefs from throughout the country combining local flavor with Thomas' English muffins. Murphy's winning horseshoe included eggs, bacon, cheese sauce, sausage gravy and hash browns on top of the English muffin. He prepared the dish on an episode of Fox & Friends to promote the contest.
