Delicata squash, like other winter squashes, has its peak season during the late summer to early fall. Depending on the region, delicata squash starts to appear in farmers’ markets and grocery stores from late August to early September. The season typically extends through late fall, sometimes into the early winter months. It’s best to purchase and consume them during this time for the freshest taste and texture. However, since it’s considered a winter squash, delicata can be stored for several months in a cool, dry place, allowing you to enjoy it even outside its peak season.
