Nutrition, per serving
Calculated from the raw ingredient quantities in the recipe below, divided by four servings.
Cassava leaves are unusual among leafy greens for how much protein and fiber they carry once pounded fine — about 7 g of fiber per serving here, largely from the leaves themselves, with the peanut paste adding both protein and most of the dish’s fat.
History
Isombe is a daily dish in Rwanda and Burundi made from fresh cassava leaves, finely pounded then slowly simmered with peanut paste, palm oil, and sometimes dried fish or local eggplant.
Pounding the leaves, traditionally done in a mortar until a coarse purée-like texture is reached, takes considerable preparation time even before cooking begins. Served with rice, plantains, or maize porridge, this dish embodies the importance of cassava in the daily diet of Africa’s Great Lakes region.
Ingredients — serves 4
- 500 g (1.1 lb) cassava leaves (fresh or frozen, pounded)
- 3 tbsp peanut paste
- 2 tbsp palm oil or vegetable oil
- 1 onion, sliced
- 1 eggplant (optional)
- Salt, chili to taste
Isombe, step by step
- Pound or finely blend the cassava leaves until you get a coarse purée-like texture.
- Heat the oil and sauté the onion until translucent.
- Add the pounded cassava leaves and a little water, then simmer covered.
- Stir in the diluted peanut paste and the diced eggplant, if using.
- Simmer gently for a long time until the mixture is soft and well blended.
- Serve hot with rice, plantains, or maize porridge.
Cooking method
Technique: fine pounding of the leaves before a long, gentle cooking, to fully soften the plant fiber.
Traditional equipment: wooden mortar and pestle, cast-iron pot for extended simmering.
Signs of doneness: the leaves should be fully tender and melted into the sauce, with no perceptible fiber left to chew.
Economic context
Cassava leaves are typically a byproduct of growing cassava for its root, and peanuts are a widely cultivated local crop — both keep isombe firmly within reach of everyday cooking in Rwanda and Burundi, eaten as routinely as any staple dish in the region.

Who this dish suits
Fits well with
- Vegetarian or plant-forward meals, when prepared without dried fish
- Diets tracking fiber intake from vegetables, given the cassava leaves’ notable fiber content
Worth knowing
- Contains peanuts — relevant for those tracking this allergen
- Cassava leaves must be cooked thoroughly and for a long time; this is a food-safety requirement of the raw leaf, not an optional step
- Often served with dried fish, which adds protein and sodium not counted in the figures above
