What Are Bambara Beans?

Bambara beans (Vigna subterranea), also called Bambara groundnuts, are edible legumes native to Africa. Although their name includes the word “groundnut,” they are not the same as peanuts. Bambara beans belong to the legume family and develop their pods underground, a growth habit they share with peanuts.

The plant is cultivated in several African countries, particularly in regions where farmers need crops that can tolerate relatively dry conditions. It is also grown in some parts of Asia and other tropical regions.

Bambara beans typically have round or slightly oval seeds, with colors that may include cream, brown, red, black, or combinations of these shades. Their flavor is mildly nutty and earthy, and their texture becomes soft and satisfying after cooking.

These beans are traditionally used in porridge, soups, stews, steamed dishes, snacks, and flour-based foods. They can be especially useful in diets that rely on plant foods because they provide both energy and protein.
