About Walnut Oil

Walnut oil is an edible oil pressed or extracted from walnut kernels. It is used in salad dressings, finishing, marinades, baking, and gentle cooking, especially when a walnut character is desirable. It is a liquid ingredient rather than a source of the kernel’s solids or crunch.

Unrefined walnut oil is aromatic, nutty, and sometimes slightly bitter, while refined oil is generally milder and more neutral. It is smooth and free-flowing, with no pulp or pieces in a clear filtered product. Heat can reduce its delicate aroma, so it is often added after cooking or used in cold dishes.

Colour ranges from pale yellow to golden or amber, depending on the walnuts and processing. The oil may be sold unrefined, refined, or blended. It can be drizzled directly, whisked into dressings, incorporated into doughs, or used sparingly in pan cooking.

Reference values for the specific food form shown. Other varieties, brands and preparations can differ.

Portions & preparation

Identify whether the oil is expeller-pressed, refined, toasted, blended, flavored, or intended for finishing, and use the actual liquid portion. A dressing or sauce may contain water, vinegar, salt, sweetener, dairy, egg, or herbs. Do not substitute walnut oil for whole walnuts when matching a reference.

Compare the right form: Match a reference for the exact walnut oil form, such as refined, unrefined, toasted, or blended oil, and specify the liquid portion used.

Diet considerations

Walnut oil is plant-derived when it is made solely from walnuts, but blends and flavored products require ingredient-list confirmation. The oil itself contains no cereal ingredient, while dressings, marinades, and sauces may add sugar, vinegar, dairy, egg, or other components. The accompanying recipe determines carbohydrate patterns and compatibility.
