Confit (, French pronunciation: ​[kɔ̃fi]) (from the French word confire, literally "to preserve") is any type of food that is cooked slowly over a long period as a method of preservation.

Confit, as a cooking term, describes when food is cooked in grease, oil, or sugar water (syrup), at a lower temperature, as opposed to deep frying. While deep frying typically takes place at temperatures of 160–230 °C (325–450 °F), confit preparations are done at a much lower temperature, such as an oil temperature of around 90 °C (200 °F), or sometimes even cooler. The term is usually used in modern cuisine to mean long, slow cooking in oil or fat at low temperatures, many having no element of preservation, such as in dishes like confit potatoes.

For meat, this method requires the meat to be salted as part of the preservation process. After salting and cooking in fat, confit can last for several months or years when sealed and stored in a cool, dark place. Confit is a specialty of southwestern France.
