Wash the butternut squash as thoroughly as possible.
Use a sharp knife to cut the unpeeled squash in half.
Use a spoon to scoop all the seeds out of the halves.
Put each half in a separate heavy-duty freezer bag and store the bags in your freezer.
Notes
Don’t forget to flash freeze the butternut squash cubes in a single layer as it prevents the cubes from clumping together.
Always label the freezer bags with the current date so that you know how long the squash has been in your freezer.
If you are cutting butternut squash into small squares, don’t discard the smaller chunks. You can use the smaller pieces to add flavor to quinoa, rice pilaf, and risotto.
