Yeah, I did think about that. But I'm running out of room in my freezer and a bag of pureed squash takes up less room than two quarts of soup.
Thanks everyone, you cleared things up for me!
I am 8 months pregnant and am in the process of freezing a bunch of stuff so my husband can cook easily after the baby is born. There is a butternut squash recipe soup we love, and I have a fresh squash that I want to cube and freeze. I've never frozen butternut squash before, so I'm wondering...
