Of all the winter squash, delicata has the shortest shelf life. It’s so thin skinned and the flesh is also pretty thin, so it just doesn’t have the keeping qualities of a thick skinned butternut. That said, a few have been known to last up to two months at my house … but you can’t count on that. They will start to develop small mold spots and soon the squash is ruined. Rinse them off to remove the farm dirt and let them dry, then store in a cool, dry place. It doesn’t have to be dark. As a matter of fact, I like leaving them out on the counter in a wire rack so I can see them daily and give them a little visual inspection to be sure nothing’s starting to spoil.
