Isombe is Rwanda's national dish. It consists of cassava leaves (pounded and cooked until tender) simmered with meat or fish, often flavored with onion, garlic, eggplant, peanut butter, and palm oil. The result is a rich, dark-green stew with a slightly smoky, earthy flavor.
Isombe is served at weddings, umuganura (harvest festival), family gatherings, and to honor guests. Its preparation is labor-intensive, traditionally a communal activity.
Similar cassava-leaf dishes exist across Central and East Africa (e.g., saka-saka in Congo, matembele in Uganda), but Rwanda's version is distinct for its frequent use of peanut butter and palm oil.
