French fries are made from thinly sliced potatoes, which are deep-fried until crispy. They are typically served hot with seasonings or condiments and can have a soft or crunchy consistency depending on the maker’s preference.

People typically eat French fries for lunch or dinner or have them as a midday snack.

There are various French fry styles, including standard cut, crinkle cut, potato wedges, curly fries, steak fries, waffle fries, shoestring fries, cottage fries and more.

Who invented the French fry?

While "French" is in the dish’s name, multiple countries claim to be the originators of fries.

In France, the first French fry recipe was documented in 1795 with Madame Mérigot’s "La Cuisinière Républicaine" cookbook – which translates to "The Republican Cook," in English.

French fries were a popular Parisian street food in the 18th- and 19th-century, according to a 2019 article from Le Figaro – a French daily morning newspaper.

The lore of Belgian fries reportedly dates back to the 1980s. Belgian journalist Jo Gérard wrote an article claiming to have found an 18th-century family manuscript that states fries were created before 1680 in the Meuse valley, where people reportedly fried potatoes when waters froze over and prevented fishing.

However, the manuscript Gérard mentioned was never made available to the public. 

Critics doubt the story because potatoes were considered a New World colony crop and weren’t easily accessible in the region during that time for working-class groups, according to French historian Thomas Beaufils, who wrote: "Les Belges" ("The Belgians"), a tourist guide.

Belgian-made French fries are known as "frites" and are a popular dish in the country.
