Even well drained it sounds too wet to me to freeze really well. OTOH, the water could just crystalize out and you'd be able to pour it off and have a cheesy, creamy, good dip that was softer and dippier than ever.

So you have a whole lot. It's not going to keep nicely in the fridge for more than a few days. Why not freeze at least some and see what happens? If it doesn't come out well from the freezer, make a half batch next time.

Good point. I will at least try - better than tossing it. (Or I will just eating nothing else for the next few days.)

Agree the texture could be compromised by freezing but not the flavor. If it's too thinned out to your liking after thawing, maybe try tossing it with hot pasta.

I was going to suggest tossing with pasta. I have never done it, but it sounds good to me. But then, everything sounds good to me, just started a diet, and has been a long, long time since I have been on a serious diet. Feeling glum.

Mayo typically doesn't freeze and thaw well....but there is enough other stuff in there that I think it would be fine. as for being watery? The vegetables have been cooked and should have released most of the water.....and I trust the spinach was squeezed a bit as well to get rid of the juice. The parm will go a long way toward sopping up any goo....I think ti will freeze just fine! Give it a good stir when thawed and of course defrost slowly preferably in the refrigerator.
