Groundnut Stew: West Africa's Other Great Peanut Dish
Not groundnut soup. Groundnut stew — thicker, earthier, built around tomatoes and a paste that takes patience. Ghana and Sierra Leone have been arguing about the original for generations.
The confusion between groundnut soup and groundnut stew is understandable and worth clearing up because they are genuinely different dishes that happen to share a primary ingredient.
Groundnut soup (maafe in its Senegalese and Malian form, nkate nkwan in Akan, peanut butter soup in diaspora shorthand) is lighter — more broth-forward, the peanut paste dissolved into a liquid that moves. It is eaten with rice, fufu, or banku, and the sauce is the thing.
Groundnut stew is thicker. It is built from a tomato base that you cook down seriously before the peanut paste enters. The peanut paste does not disappear into a broth — it becomes the body of the stew. It coats. It sticks to the spoon. Eaten over rice, it sits rather than pools.
Ghana claims the form. Sierra Leone has its own version with different spicing. Both are correct. The principle is the same.
## The Architecture of the Stew
The tomato base is not optional. Groundnut stew without a properly cooked tomato base is peanut sauce, which is a different and lesser thing. The tomatoes — fresh, blended, cooked in oil until the water is completely gone and the paste is frying — are what give the stew its depth and its color. This step takes twenty minutes of patience. You cook the tomatoes until they have lost all their raw acidity and have become something else: concentrated, slightly caramelized, dark.
Onion goes in first, in oil, until soft. Then the blended tomatoes. Then you wait. The tomatoes will bubble and spit and gradually tighten. When the oil begins to rise to the surface and the paste is frying rather than steaming, you are ready for the next step.
The peanut paste is the body. Natural peanut butter — the kind with one ingredient, peanuts — is the correct diaspora substitute for fresh-ground West African groundnuts. Do not use American commercial peanut butter with sugar and stabilizers. The sweetness is wrong. The texture is wrong.
Thin the paste with warm water before you add it to the pot. Adding cold paste to a hot base seizes it. Warm the water separately, mix it into the paste until you have a smooth, pourable consistency, then introduce it to the tomato base gradually while stirring.
The paste will thicken the whole stew immediately. Keep stirring. Keep the heat medium. It will try to stick to the bottom and burn if you ignore it.
The protein is flexible. Chicken is the most common — bone-in, skins on, cooked with the stew rather than separately so it takes on the color and flavor of the sauce. Goat meat works well. Beef works. For Sierra Leonean groundnut stew, smoked fish is often added alongside the meat, which gives the stew a depth that is different from the Ghanaian version.
## Full Recipe — Groundnut Stew (Ghanaian version, serves 4)
- 1 whole chicken, cut into pieces (or 1 kg bone-in chicken pieces) - 3 tablespoons neutral oil - 2 large onions, one blended, one sliced - 4–5 large tomatoes, blended (or one 400g tin + 2 fresh) - 1 tablespoon tomato paste - 250g natural peanut butter - 500ml warm water (for thinning the paste) - 2 tablespoons ground crayfish - 1–2 scotch bonnet peppers, blended - Salt to taste - Maggi or equivalent (optional but common in Ghanaian cooking)
Season the chicken with salt, blended onion, and scotch bonnet. Set aside for at least 30 minutes. Parboil if you prefer — many Ghanaian cooks parboil their chicken before finishing in the stew. Others add it raw to the stew and let it cook through. Both work.
Heat oil in a heavy pot. Add sliced onion and cook until translucent and beginning to brown at the edges.
Add blended tomatoes and tomato paste. This is the patience step. Cook on medium heat, stirring occasionally, until the tomatoes have fully cooked down — no more bubbling from water content, oil beginning to surface. Twenty minutes minimum. The color will deepen from bright red to a darker, richer shade.
Add the chicken to the tomato base. Stir to coat. Add enough water to almost cover. Bring to a boil, reduce heat, and simmer for 20–25 minutes.
While the chicken cooks, thin the peanut butter with the warm water. Stir until completely smooth and pourable.
Add the ground crayfish and blended scotch bonnet to the pot. Taste for salt.
Reduce heat to low before adding the peanut paste. Add it slowly, stirring constantly. The stew will thicken dramatically. If it becomes too thick, add a small amount of water. You want it to coat a spoon but still be scoopable.
Continue cooking on low heat for 20 minutes, stirring frequently to prevent sticking. The stew is ready when the oil rises to the surface in small pools — this is the visual signal that the peanut paste has fully cooked and the raw flavors are gone.
Serve over white rice. Plain rice, nothing added — the stew is enough.
## The Sierra Leonean Version
The key differences: smoked fish (herrings or catfish) added with the meat, creating a more complex umami layer. Some versions use leafy greens (cassava leaves, potato leaves) stirred in near the end. The spicing can include Maggi as standard rather than optional, and some versions add ginger alongside the scotch bonnet.
The Sierra Leonean version is slightly less sweet — the peanut paste is used more sparingly so the stew is thicker relative to a smaller peanut component.
Both are correct. If you have Ghanaian relatives and Sierra Leonean relatives, do not introduce this topic at a family gathering.
## What to Do With Leftovers
Groundnut stew gets better the next day. The flavors settle overnight. The oil, which has risen to the surface, integrates back in when you reheat it. Reheat gently on low, stirring — do not microwave at high heat or the paste will seize.
Cold groundnut stew straight from the refrigerator, with bread, is a private pleasure that many diaspora people have but do not advertise.
The stew freezes well. Portion it into containers after it has cooled completely. Thaw in the refrigerator overnight, reheat gently. The peanut paste may need a small splash of water to loosen as it thaws.
