Butternut squash is a versatile fall staple, but once it hits the oven, its shelf life changes. When stored properly in an airtight container, cooked butternut squash remains a delicious and safe addition to your meals for several days. Because of its dense texture and low moisture content compared to leafy greens, it holds up well, but you should still monitor it closely as the days pass. Watch for changes in texture or any signs of fermentation to ensure your next bowl of roasted goodness is perfectly fresh.

Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
