Yes they are, I did this with squash, carrots, and some others that I can't think of right now. I would put the cut up pieces in individual serving size baggies, then put 10 or so of these into a big freezer bag. Can thaw in fridge or dip in cool water for a bit. It's been a while since I did this, DS is nearly 4, but I made all of his food with guidance from the book Super Baby food.
