Lupini beans

Lupini beans are the edible seeds of lupin plants, especially species such as *Lupinus albus*.

By Ethan Anderson| Reviewed by Olivia Bennett, Standards & Fact-Checking Lead| Updated July 26, 2026|2 min read| Fact-checked

Lupini beans are the edible seeds of plants in the genus *Lupinus*, particularly species such as *Lupinus albus*. They are a traditional food in the Mediterranean basin, North Africa, and parts of Latin America, where they are commonly eaten pickled, brined, or as a snack. Known for their high protein and fibre content, they require processing to remove naturally bitter alkaloids before eating.

Description

Lupini beans are yellow, firm legumes with a mild flavour and a slightly bitter edge. They are distinct from many other beans because of their very low starch content and their use as a snack food rather than only as a cooked ingredient.

Culinary use

They are commonly served brined, pickled, or canned and may be eaten on their own or added to salads, bowls, and stews. In some regions they are a traditional street or bar snack.

Nutrition

Lupini beans are widely described as high in protein and fibre and a source of minerals such as iron, magnesium, potassium, zinc, and manganese. Their macronutrient profile is often noted for low digestible carbohydrate compared with many other legumes.

Preparation and safety

Many lupin varieties contain bitter alkaloids that must be removed by soaking, rinsing, or brining before consumption. This preparation is essential to make the beans palatable and safe.
