Winter varieties like butternut squash can be a filling addition to cool weather staples like stews and casseroles. Some types are substantial enough to be the star of the meal when they’re stuffed, such as acorn or spaghetti squashes. And according to Harvest to Table, there are some winter squash varieties that are best when used for baking or in desserts, like a pumpkin pie. No matter how you use winter squash, there’s one thing you need to remember to get the most longevity from these vegetables.
As reported by All Recipes, winter squashes are a type of food that should never be refrigerated. Because of the high humidity and cold temperatures in the fridge, winter squashes can deteriorate rapidly. To get the most longevity out of your winter squash varieties, store them in a cool, dry place that is between 50 and 55 degrees Fahrenheit. If stored correctly, winter squashes can stay good for up to six months.
