NOTE:- Question at the end!
So I made the recipe and froze four individual dishes. A bit stuffed, I could have easily done 5 or even 6 small ones.
There is ground beef (and onion) on the bottom. Then some frozen green beans and corn (was supposed to be frozen but I used canned corn).
then a Mushroom soup and a Celery soup on top.

the soups were very thick but I left them that way (piled in the centre) thinking they would spread out and dilute with the frozen vegies underneath. I had made this dish twice previously in a 9x13 dish and both times the soup 'melted' into the vegies and meat. The only difference was the vegies, before I used frozen peas and corn (diced) and this time, as said above.

Then the Tator Tots are piled on top. I ate that last one in the middle, raw.
(Hey! Com'on! what was I supposed to do? Put one lonely tator back in the freezer? all by itself? would get so lonely!)
Then I wrapped in foil and also plastic wrap and then ziplock and froze.
I defrosted and baked in oven (with foil for 3/4 of the time) til it measured about 175 in the middle and seemed to be bubbling around the edges.
Was certainly hot enough but the soup did not become gravy and soak into the rest of the "casserole".
How do I save the next ones?
After defrosting,
do I deconstruct?
remove tator tots?
Mix a bit of milk thru the balance? or maybe water?
All suggestions welcome!
