Golden, tender, and warm papa rellenas are traditional Peruvian stuffed potatoes, a type of croquette consisting of fried mashed potatoes with a meat filling on the interior. The filling usually consists of chopped beef that is mixed with onions and cumin.
In Peru, the typical accompaniment to papa rellena is salsa Criolla (hot Creole sauce). The dish is popular as a street food, but it is also served at restaurants and prepared at home. A popular theory suggests that the dish was invented in 1879, in the height of the War of the Pacific by Peruvian soldiers who needed durable, pre-made food, so they would cook the meat, season it, and place it into the hollowed potatoes, which were later fried and wrapped in cloths.
