A deeply flavourful Burundian dish of slow-cooked cassava leaves with peanuts, palm oil, and aromatic spices.
Isombe is one of the most celebrated dishes in Burundian cuisine, made from cassava leaves that are pounded, boiled, and then simmered in a rich sauce of ground peanuts, palm oil, and aromatics. The cassava leaves undergo a transformation during cooking — their bitterness and toxicity are removed through extended boiling, leaving a silky, deep green sauce with an earthy complexity that is unique. Isombe is eaten throughout the Great Lakes region of central Africa, where cassava is a dual-purpose crop providing both starchy roots and protein-rich leaves. In Burundi it is a dish of cultural pride, often served at celebrations.

If using fresh leaves, boil in a large pot of unsalted water for 45 minutes, changing the water twice to remove bitterness. If using frozen, thaw and squeeze out excess liquid. Drain well and roughly chop.
Heat palm oil in a large pot over medium heat. Fry onion for 5 minutes until softened. Add garlic and chilli, cook 1 minute.
Stir in the pre-cooked cassava leaves and cook for 5 minutes, stirring frequently.
Whisk peanut butter into the water or stock until smooth. Pour over the leaves and stir to combine.
Simmer on low heat for 20–30 minutes, stirring occasionally, until the sauce is thick, creamy, and fully flavoured. Season with salt and pepper.
Serve hot with ugali, rice, or fried plantain.
Changing the water while pre-cooking fresh cassava leaves is essential — it removes harmful cyanogenic compounds.
Frozen cassava leaves are widely available in African grocery stores and eliminate the pre-boiling step.
Red palm oil gives isombe its characteristic golden-orange hue — do not substitute with regular oil.
Pruebe y ajuste la sal al final — los sabores se concentran a medida que los líquidos se reducen, y un último pellizco de sal escamosa afilará todo el plato.
Isombe with smoked fish: add flaked smoked fish in the last 10 minutes of cooking.
Isombe with coconut milk: replace stock with coconut milk for a creamier, milder version.
Vegetariano: cambiar la proteína por hongos ostra real asados, tofu ahumado o garbanzos cocidos — ajustar el condimento ligeramente hacia arriba para compensar.
Spicier: add a finely chopped fresh chile or a teaspoon of crushed Aleppo/Urfa pepper to the aromatics for warm, layered heat instead of a single sharp hit.
Refrigerate for up to 4 days. The flavours deepen overnight making it even better the next day. Freezes well for 1 month.
Isombe is believed to have been part of Burundian and Rwandan cuisine for several centuries, predating the introduction of cassava to the region. Similar dishes appear across the Great Lakes region from DR Congo to Tanzania, reflecting shared culinary heritage among Bantu-speaking communities.
Yes, once properly prepared. Fresh cassava leaves must be boiled with water changes to remove cyanogenic glycosides. Commercially frozen and dried leaves have been pre-processed and are safe to use directly.
Coconut oil with a pinch of turmeric for colour is the closest substitute, though the flavour will differ.
Sí — la mayoría de los componentes se pueden preparar con un día de anticipación y refrigerar por separado. Recaliente suavemente y ensamble justo antes de servir para que las texturas se mantengan distintas.
Manténgase cerca del papel que juega cada ingrediente: cambie los aromáticos por otros similares (chalote por cebolla, lima por limón), y mantenga el equilibrio de grasa-ácido-sal intacto. Las mezclas de especias generalmente se pueden aproximar con lo que está en la despensa.
