Burundi's affordable everyday vegetarian main — red beans and cassava chunks slow-cooked with onion, leek, garlic, tomato, and palm oil into a thick, hearty, dark-amber stew. Served with mutsima or rice. A protein-dense staple of the rural and urban poor that has fed Burundi through every economic season.
Renge is a Burundian everyday plant-protein meal combining two staples that grow in every Burundian home garden: red beans (known locally as ibiharage) and cassava (umuhogo or imyumbati); the bean-and-cassava combination is also known simply as imyumbati na ibiharage. It comes straight out of the country's farming traditions: kitchen gardens, mixed cropping (beans + cassava + sweet potato + plantain on the same plot), and a sustainable starch-and-protein pairing. Beans are Burundi's most popular and beloved food — cheap, ubiquitous, and nourishing — and fried beans (ibiharage) are regarded as a national dish. Bujumbura's working-class neighborhoods serve this daily; rural northern Burundi has it 4-5 times a week. It is plain, filling, and nourishing.
Spoon up renge from a deep bowl — chunks of pale-yellow cassava soft and creamy, dark-red beans glossy with the tomato-palm-oil gravy, leek and onion barely visible after the slow cook. First bite: the cassava breaks under the spoon (slightly chewy outer, soft inner), beans creamy-earthy, gravy rich-savory with tomato sweetness and palm-oil's tropical-fruity note. Salt-grounded, ginger-warming, chili-back-burning. With mutsima to scoop, this is rural Burundi's everyday-perfect meal.
Cassava and beans cook together in the final stage because they have compatible textures — cassava is starchier (50% starch), beans are protein-rich (25%). The cassava's pectin acts as a natural thickener for the gravy. Mashing a few cassava pieces at the end intentionally releases starch, thickening the sauce. The palm oil's natural color (from carotenoids) deepens the gravy's red-amber hue without artificial additives.
Variations
Renge ya inyama adds 250 g cubed beef or goat for festive versions. Renge ya ndagala adds 100 g smoked sardines for fish-protein. Plantain renge substitutes plantain for cassava — coastal-Burundi variant. Sweet-potato renge uses sweet potato — sweeter and softer. Pure-bean renge skips the cassava — Rwanda-influenced. Modern Bujumbura version adds coconut milk and curry powder for a fancier preparation.

How it's made
12 steps · 30 min active + 1 hour 10 min waiting
- 1480 min
Soak 350 g dried red kidney beans overnight (8+ hours) in cold water with 1 tsp salt. Drain.
- 250 min
Boil beans in fresh water with 2 bay leaves 40-50 min until tender. Drain, reserving 300 ml liquid.
Watch outBoil the kidney beans until fully tender before they join the pot — reserve some of the cooking liquid, because that starchy water loosens and enriches the final gravy.
- 318 min
Peel and cube 700 g cassava root into 3-cm chunks. Boil in salted water 15 min until just-tender. Drain.
- 411 min
In a heavy pot, heat 3 tbsp red palm oil over medium heat. Sauté 1 large chopped onion + 1 chopped leek 8 min until golden.
- 52 min
Add 4 minced garlic cloves + 1 tbsp grated ginger + 1 minced bird's eye chili; cook 1 min.
- 63 min
Add 1 tbsp tomato paste + 1 tsp paprika + 1 tsp salt + ½ tsp pepper. Cook 2 min.
- 77 min
Add 2 chopped tomatoes; cook 6 min until thick.
Watch outCook the tomatoes down until thick and jammy — you want the watery rawness gone before the beans and cassava go in, or the gravy stays thin.
- 83 min
Add the cooked beans + cassava + 250 ml reserved bean liquid. Stir gently.
- 917 min
Cover; simmer on low 15-18 min, letting the flavors meld. The cassava should be fully tender and starting to fall apart at the edges.
- 102 min
Mash a few cassava pieces against the pot side to thicken the broth.
Watch outOnce everything's melded, mash a few cassava pieces against the pot side — that released starch is what thickens the broth into a proper clingy gravy.
- 112 min
Taste; adjust salt. Stir in 1 tbsp lemon juice and chopped scallions.
- 123 min
Serve hot in deep bowls over mutsima or rice. Drizzle with a touch of palm oil for color.
