peanut oil for cooking

Oils & FatsYear-round; peanuts are harvested annually in late summer and fall in major producing regions, but refined peanut oil is shelf-stable and commercially available throughout the year.

Peanut oil is rich in unsaturated fats, particularly oleic acid (monounsaturated) and linoleic acid (polyunsaturated), and contains vitamin E as a natural antioxidant. It contains no trans fats in its naturally refined state.

About

Peanut oil is a vegetable oil derived from the seeds of Arachis hypogaea, the peanut plant, which is native to South America but now cultivated extensively in Asia, Africa, and North America. The oil is extracted through pressing or solvent extraction of dried peanut kernels, yielding a clear, mild-flavored oil with a pale golden hue. It contains approximately 80% unsaturated fats, including oleic and linoleic acids, and features a neutral taste with a subtle nutty undertone. Refined peanut oil has a high smoke point (around 450°F/232°C), making it suitable for high-heat cooking, while unrefined or crude peanut oil retains more peanut flavor and aroma but has a lower smoke point.

Culinary Uses

Peanut oil is widely used in cuisines where high-heat cooking is essential, particularly in Chinese, Southeast Asian, and Indian cooking traditions. It is the preferred oil for stir-frying, deep-frying, and wok cooking due to its high smoke point and ability to impart minimal flavor interference. The oil is also used in salad dressings, marinades, and as a finishing oil in unrefined form for enhanced peanut flavor. In West African and American Southern cuisines, it is employed for frying and sautéing. Its neutral character makes it versatile for both sweet and savory applications.

Forms & Preparations

Refined oil — Processed and filtered to remove impurities and allergens; neutral flavor, high smoke point, suitable for all cooking methods.
Unrefined (crude) oil — Minimally processed, retaining peanut flavor and aroma; lower smoke point, best used in dressings, finishing, and low-heat applications.
Cold-pressed oil — Extracted without heat or chemicals, preserving nutrients and flavor; typically unrefined with a robust peanut taste and lower smoke point.
Roasted peanut oil — Made from roasted peanuts, delivering deeper, richer nutty flavor; often used in finishing applications and dressings rather than high-heat cooking.
