Goguma-jeon (고구마전) is a Korean savory pancake made primarily from sweet potatoes, classified as a type of "jeon" (전), a term for pan-fried battered or coated foods in Korean cuisine. Traditional preparation involves peeling and slicing sweet potatoes into thin rounds or matchsticks, coating them lightly with wheat flour, and pan-frying them in oil until golden and crisp on the outside. Occasionally, egg wash is used to enhance the texture and flavor.
Goguma-jeon is typically consumed as a banchan (side dish) or as a snack, and it is known for its subtle natural sweetness from the sweet potatoes.
