Mbongo Tchobi is a bold, aromatic black stew originating with the Bassa people of Cameroon. Its distinctive deep color and flavor come from mbongo spice, an intensely fragrant seed that is traditionally charred, ground, and added to the sauce. Because of its rich, smoky aroma and satisfying heat, the dish has become popular across Cameroon and in Cameroonian communities abroad.

The ground mbongo spice is commonly sold in markets in Cameroon under names like “mbongo spice” or the French “épice mbongo.” Outside the country, you may find it in specialty African food shops. In addition to mbongo, the stew typically includes tomatoes, onions, garlic, pepper, and njangsa, a nutty seed used in Cameroonian cooking that adds depth to soups and stews.

Mbongo is most often served with a starchy accompaniment such as boiled plantains, yams, or cassava. I enjoyed mine with white yam — perfectly boiled and crumbly — which complements the earthy, nutty sauce.

Below is a clear, practical recipe for making Mbongo Tchobi at home. The method is straightforward and can be adapted if you prefer chicken or pork instead of fish.

Ingredients
- 2 large fish of choice (I used tilapia) about 2 pounds
- 4 teaspoons ground mbongo spice
- 30 seeds njangsa
- 2 seeds African nutmeg (Ehuru/Pebe) peeled
- 3 small seasoning cubes (Maggi)
- 1 1/2 teaspoon salt
- 2 large tomatoes (or four small ones) roughly chopped
- 1 large onion
- 1/2 celery stalk chopped
- 1/2 stem of leeks chopped
- 7 garlic cloves, peeled
- 1/2 inch ginger root, peeled
- 1/2- 1 cup vegetable oil
- 1/4 teaspoon white pepper (optional)
- 1 habanero or hot pepper (optional)
- 2 stems green onions (optional) for garnish
Instructions
-
Clean the fish and cut it into steaks. Rinse well, sprinkle with a pinch of salt, and set aside.
-
In a blender, combine tomatoes, half the onion, garlic, ginger, leeks, celery, African nutmeg, njangsa, and mbongo spice with about 1/2 cup water. Blend to a smooth paste.
-
Pour the blended mixture over the fish and allow it to marinate briefly while you prepare the pan.
-
Heat the vegetable oil in a pot. Chop the remaining onion and sauté until fragrant.
-
Add the fish with the blended spice mixture to the sautéed onions. Crumble the seasoning cubes over the mixture and add salt. If using white pepper and hot pepper, add them now—either blended with the paste or whole, depending on your heat preference.
-
Cover and cook for about 15 minutes. Check seasoning and adjust to taste. If the stew is very thick, add a little water to loosen it, then cook for another 5 minutes.
-
Serve warm with boiled yams, plantains, or your preferred starchy side. Garnish with chopped green onions if desired.
Notes
If you want more heat, blend the hot pepper with the other ingredients; otherwise add it whole to release milder heat.
