How to use Acorn Squash in the kitchen

Wash, carefully halve, remove the seeds and roast until tender, or cook into soup, puree or stuffed dishes. Do not confuse the raw reference weight with the weight of a cooked serving.

Cooking, peeling, draining and added oil or sugar can change nutrition values. The calculator scales the recorded reference values by weight.

Direct USDA records are used where available; closest-profile entries are explicitly labelled and remain approximate. Blank fields mean that the source did not report a value. General information only; not medical advice. Primary composition reference: USDA FoodData Central.
