groundnuts

Nuts & SeedsGroundnuts are harvested in autumn (September through November in the Northern Hemisphere), though as a dried, shelf-stable commodity they are available year-round globally. Regional variations in harvest timing apply to major producing countries including India, China, and West Africa.

Groundnuts are rich in plant-based protein, healthy monounsaturated and polyunsaturated fats, and contain substantial amounts of vitamin E, magnesium, and folate. They also provide dietary fiber and resveratrol, a beneficial polyphenol antioxidant.

About

Groundnuts (Arachis hypogaea), commonly known as peanuts in North America and Australia, are legumes native to South America that develop their fruit underground after pollination. Unlike tree nuts, groundnuts are members of the Fabaceae family and consist of an edible seed kernel enclosed in a thin papery shell within a woody pod. The plant grows as a bush, producing distinctive flowers that elongate and push into the soil where pod development occurs. Groundnuts have a mild, slightly sweet nutty flavor with an oily texture when raw, and develop richer, deeper flavors when roasted. Major cultivars include Spanish, Valencia, Virginia, and Runner varieties, which vary in size, oil content, and flavor intensity.

Culinary Uses

Groundnuts are a versatile ingredient used extensively across African, Asian, and American cuisines. Roasted whole kernels serve as snacks or are pressed into peanut butter, a staple ingredient in both sweet and savory applications. In African cuisine, groundnuts feature prominently in stews, sauces (particularly West African peanut-based gravies), and as a thickening agent for curries. Asian cuisines incorporate ground peanuts into satay sauces, noodle dishes, and desserts. The ingredient may be blanched, roasted, salted, or processed into paste, oil, and flour; roasting amplifies the characteristic peanut flavor and is the preferred preparation method for snacking and most culinary applications.

Forms & Preparations

Whole roasted kernels (in-shell or blanched) — Roasted peanuts retaining the skin or blanched to remove it; used as snacks, garnishes, or crushed for incorporation into dishes. Whole kernels provide texture and visual appeal.
Peanut butter — Ground whole kernels processed into a smooth or chunky paste; a staple spread and baking ingredient used in both sweet and savory preparations.
Ground peanuts (powder/flour) — Finely ground dried kernels used as a thickening agent in stews, curries, and sauces, or as a coating for fried foods and baked goods.
Peanut oil — Cold-pressed or refined oil extracted from kernels; used for cooking, frying, and as a neutral-flavored culinary oil with a high smoke point.
Raw/blanched kernels — Unroasted peanuts with or without the papery skin; used in cooking applications where a milder flavor is desired, or as a base for further processing.
Peanut flour (defatted) — Ground peanuts with most oil removed; used in baking and as a protein supplement with reduced fat content compared to whole-kernel flour.

Substitutes

Unknown — Similar nutritional profile and versatility; can replace whole roasted groundnuts 1:1 in snacking applications, though flavor is milder. May replace in sauces but will alter the final flavor profile.
Unknown — Richer, buttery flavor; use in equal amounts as a substitute in sauces and pastes, though the result will be less earthy. Better for sweet applications than savory stews.
Unknown — More intense flavor and lower oil content; use at 75% of the groundnut quantity in sauces and dishes, as sesame is more pungent. Works well in Asian-style preparations.
Unknown — Milder, slightly sweet profile; substitute 1:1 in baking and desserts, but will not replicate the earthiness in savory dishes. Better suited to sweet applications.
Unknown — Use at reduced quantity (50-75% of groundnut butter called for) due to stronger flavor; best for dressings and sauces rather than direct paste replacement.
