ToggleHow to freeze butternut squash the right way

Step 1: Prepare the squash
Begin by washing the squash thoroughly. Next, peel the skin, cut off the stem, and remove the seeds with a spoon.
Afterward, cut the squash into smaller, manageable chunks or cubes, typically around one inch in size. This step not only makes it easier to store but also speeds up the cooking process when you’re ready to consume it.
Step 2: Blanch
Blanching the squash before freezing is an optional step, but it can help preserve its color, texture, and nutritional value.
To blanch, boil the squash pieces for about 3-5 minutes, then immediately transfer them to an ice bath to stop the cooking process. After cooling, pat the squash dry with paper towels.

Step 3: Flash freeze
After blanching, the next step is flash freezing. This process ensures that the pieces remain separate, making it easier to use just the amount you need later on.
To do this, spread your cut butternut squash on a parchment-lined baking sheet in a single layer and freeze them for a couple of hours.
Step 4: Store the squash
Once the squash is frozen, transfer the pieces to airtight freezer bags or containers. Make sure to remove as much air as possible before sealing the bags.
Label and date the containers, and store them in the freezer. Properly stored, butternut squash can last for up to a year.
Alternative methods for freezing butternut squash
In addition to freezing cubes or slices, you can also freeze butternut squash in other forms:
Pureed squash
If you often use squash in soups or as a baby food, consider pureeing it before freezing. This method ensures a smooth texture and makes it easy to thaw and use directly.
Squash noodles
Spiralized squash noodles can be frozen uncooked. Just place them in a freezer bag, removing as much air as possible, and they’ll be ready to toss into a stir-fry or boil as a pasta substitute.
Cooked squash
You can also freeze cooked butternut squash. Simply allow it to cool before freezing, ensuring it’s stored in portion sizes convenient for future meals.
Tips for using frozen butternut squash
When you’re ready to use your frozen squash, there are several options depending on how it was prepared.
For raw, cubed squash, you can add it directly to stews, casseroles, or soups, allowing it to cook from frozen. If you’ve frozen squash puree or soup, it can be thawed in the refrigerator overnight or reheated directly on the stovetop.
It’s important to note that while frozen squash may have a slightly softer texture after thawing, this should not deter you from using it in various dishes.
Roasting, for example, can help to bring back some of the firmness and enhance the natural sweetness of the squash.
