I'd say go ahead and freeze it. Obviously, won't be as good as fresh, but what generally is after you've frozen and reheated somethng (okay people, don't actually go answering that, because I'm sure there are recipes that make the statement wrong).
I froze and reheated (I think it was) LauraB's California Dreamin' Baked Potato Soup. Freeze potatoes AND sourcream AND cheese you say???
Well, it was left to my RM to finish it up, so I wasn't too concerned
ANYWAY! Go ahead and freeze it - there's no harm in trying!
