Butternut squash is a versatile vegetable. It can be cooked, preserved, and frozen. This squash is also a good source of vitamins and minerals. The taste is sweet and nutty. Besides being nutritious, it is a low-calorie food.

Butternut squash can be frozen for longer periods. If you have a pressure canner, it can be canned. A half-pint jar holds 350 grams of butternut squash.

To freeze, slice the squash into uniform, one-inch cubes. Place the slices on a cookie sheet in a single layer. Cover with plastic wrap. Leave about a half-inch of headspace. Refrigerate the jars for 24 hours.

Before freezing, it is important to ensure that the jars have been sterilized. Wash the jars and rims. Once the jars are filled, you can process them in a pressure canner for 90 minutes for quarts and 55 minutes for pints.

When preparing the jars, remember to leave about 1 inch of headspace. Also, don’t forget to close and seal the jars. Having the proper lids and rings is important.

If you aren’t using a pressure canner, you can freeze butternut squash in a freezer bag. You can also dehydrate the squash. But be sure to keep the jars in a cool, dark place.

Most hard, root vegetables, including swede, carrots, and parsnips, can be prepared using this technique.

Butternut squash is frequently prepared by roasting it with other veggies and herbs. While there are many vegetable combinations you can attempt, we advise you to start with carrot, squash, leeks, onion, and celeriac.

Here is how we cook butternut squash and freeze it:

  • Prepare your vegetables by coarsely cutting them all into the same size pieces.
  • Vegetables are roasted by placing them in a roasting pan, dousing them with olive oil, and then flavoring them with herbs. Roast for 30 to 40 minutes at 200C in the oven, or until everything is cooked through and starting to brown.
  • Allow everything to cool.
  • Put the servings in freezer bags that can be sealed after they have cooled. Each bag should include a part of the food. This eliminates the need for flash freezing and enables you to take a portion as needed.
  • Last but not least, put it in the freezer. After 30 minutes, you can shake the bag to keep it from clumping altogether.

What does Blanching do?

Squash that has been blanched before freezing prevents the development of enzymes that alter the flavor of frozen squash. It’s not for safety; rather, it’s to keep the squash’s flavor, texture, color, and nutrients.

Whether you blanch it or not, its shelf life is the same. The taste and texture of the squash should be ok if consumed within 4 to 6 months.

Still, blanch those butternuts for the finest results! Look at this recipe for blanched kale for a fantastic illustration.

How to Prepare your Squash?

Okay, let’s discuss freezer preparation. What steps must you take to prepare your butternut squash for freezing? A freezer-safe storage container is required. You can use any freezer-safe plastic container or resealable freezer bag. Your storage container needs to be both airtight and sizable enough to accommodate all the squash comfortably without exploding.

The squash doesn’t even need to be blanched, even though some people advise it. In my experience, freezing squash that has been blanched or not makes no difference. I usually think it tastes the same and always comes out fresh, but you might have a different opinion. To determine whether the way tastes better, it could be worthwhile to test both.

The butternut squash can be blanched by boiling it for a brief period at a high temperature in a pot of water, then immediately dropping it into an ice bath. Then, immediately place it in your freezer. Make sure to first wipe off any extra water.

This prevents enzymes from gradually degrading over time. It is intended to prevent the squash from spoiling so rapidly and prolong its freshness. This is crucial for berries and many other types of fruits and vegetables since it makes them last longer in storage and tastes better when you’re ready to utilize them. The butternut squash may benefit from it as well, but I don’t think it’s required.

The squash can be kept either raw or cooked. Both ways are effective, and you can use essentially the same technique in any case.

How should raw butternut squash be frozen? Immediately put it in a freezer-safe container. Make sure to let out as much air as you can if you’re using a plastic bag. You can slice, dice, or even eat the squash whole. I’ve found that cutting it into more manageable portions that I can then break off as needed works best for long-term storage. To avoid having to break off any frozen squash to utilize it, you could also wish to freeze smaller chunks in separate bags.

What about cooking butternut squash and freezing it? Use the same procedure as described above to freeze squash, but allow it to cool to room temperature first before storing it. Once more, before storing the squash, you might want to cut it into manageable, little pieces. It could be difficult to remove only what you need from the squash once it has frozen firm.

Does Butternut Squash Freeze Well?

Depending on how it will be prepared, fresh or frozen food may be preferred. Fresh squash works best in dishes where texture counts because frozen squash has a distinct consistency from fresh squash. However, frozen works just as well for purees, soups, and stews.
