How to Tell if Your Butternut Squash Has Gone Bad?

Here are some ways that you can tell if your butternut squash has gone bad and needs to be thrown out. As always, when in doubt, throw it out.

Feel it: Pick up your butternut squash and give it a good feel. Your butternut squash should feel firm; if you notice any spots that feel soft or mushy, your squash has gone bad. If your butternut squash feels hollow or if it is leaking liquid, it needs to be thrown out.

Appearance: Check your butternut squash for visible signs of rot or mold. Mold is generally most common on cooked butternut squash. Make sure that the color, both on the surface and inside the butternut squash, is normal.

Deal with rot: If you notice only small parts of your butternut squash have begun to rot, it’s actually still safe to consume the other parts. Just cut away the rot and consume as normal.

How to Store Butternut Squash?

You know that you can keep your butternut squash outside, in the fridge, or in the freezer for so long, and how to tell if it has gone bad. Now, let’s talk about how to make sure you’re storing it in the correct way.

Store it at the right temperature: The best temperature for uncut butternut squash, and the one that will give the longest shelf life, is between 50 and 60 degrees Fahrenheit, or 10 to 15 degrees Celsius. If you don’t have access to a place at this temperature, just keep it in a cool place.

Remove the packaging and store it alone: If your butternut squash came in any kind of packaging, remove it once you get it home. Make sure to keep it stored by itself, or at the very least away from any fruits that are preparing to ripen. Ripening fruits that are near butternut squash will cause it to deteriorate faster.

Keep it sealed: After you’ve cut, sliced, or cooked your butternut squash, put it in an airtight container or wrap it up in aluminium foil or plastic wrap.

How to Freeze Butternut Squash?

We established above that you can freeze butternut squash, so how do you do it? Let’s talk about it so that you know exactly how to keep your butternut squash in perfect condition for months.

Remove the skin, stem, and seeds: If you’re going to be freezing raw butternut squash, you need to skin it and remove the stem and seeds before freezing it.

Chunk it or mash it: After you’ve done the above step, then you need to cut the raw butternut squash up into chunks or mash it. Chunks need to be lined out on wax paper and frozen for an hour before they can be placed in a freezer bag or freezer-safe container and stored.

Label it: Cooked butternut squash should also be stored in a freezer-safe container. Regardless of what you’re putting in the freezer, put the date of freezing on the container or somewhere you’ll remember it. This way, you’ll know exactly how long it’s been in there for when you take it out of the freezer ages from now.

How to Thaw Butternut Squash?

Now that you know how to freeze your butternut squash, it’s time to learn how to thaw it back out again when you’re ready to consume it.

Unlike a lot of foods, the fridge isn’t the best place for thawing out frozen raw butternut squash. Doing this will cause it to develop a mushy texture and lose quality. Cooked butternut squash, on the other hand, can be thawed in the fridge overnight.

Raw butternut squash should be cooked straight out of the freezer to preserve its quality. Remember to use your butternut squash before the two-year mark, as otherwise it will start to go bad.
