Expiration & Storage Tips
When does kabocha squash expire?
Kabocha squash can be quite a long-lasting vegetable. If it's kept unopened and in a cool, dark place, it can last for about 1 to 3 months. Compared to the print date on the package, the squash should still be in good condition upon purchase, as it's typically harvested when mature. Once it's been cut open, however, you should refrigerate any leftovers and aim to use them within 1 to 2 weeks. If you freeze cooked kabocha squash, it can last for several months, though the texture may change slightly upon thawing. If the squash was already cut at the store, it'll likely last for about a week if kept refrigerated.
How do you tell if kabocha squash is bad?
The easiest way to know if your kabocha squash has gone bad is by checking its skin. If there are any soft or moist spots or signs of mold, it's likely time to throw it out. You should also sniff the squash — if it has an off or sour smell, that's another indication that it's spoiled. If you've cut into the squash and stored it in the fridge, always remember to check for any slimy texture or foul smell before use.
Tips for storing kabocha squash to extend shelf life
• Keep the squash in a cool, dark place like a pantry or basement for optimal lifespan.
• If you cut into the squash but don’t use all of it, wrap the cut side tightly in plastic wrap, then store it in the fridge. This will help prevent moisture loss.
• To freeze kabocha squash, roast or steam it first, then let it cool completely before dividing it into portions and freezing it in freezer-safe bags.
• Remember to properly thaw frozen squash before use — you can do this by placing it in the fridge overnight, or using a microwaving it on a low setting until it's easy to cut or puree.
