A small, deeply ribbed winter squash with dark green skin and sweet yellow-orange flesh, often halved, seeded, and baked with butter and brown sugar. It is one of the most widely cultivated Cucurbita pepo varieties, prized for its mild, nutty-sweet flavor.
History & Origins
Acorn squash was domesticated by Indigenous peoples of North and Central America thousands of years ago as part of the Cucurbita pepo lineage, which also gave rise to pumpkins and zucchini. Following sustained cultivation by tribes such as the Iroquois and Pawnee, it spread to Europe after sustained contact in the 16th century. Today it is grown commercially across the United States, Mexico, and parts of Europe, with popular cultivars including 'Table Queen' and 'Cream of the Crop.'
