When my grandmother became very ill, my mother was called to see her and knew she would be away from home for over a month. She completely cooked the dinners and packaged them for my father and sister who were left behind. They turned out much better than meals you would get at the supermarket.
She cooked everything through as if to serve it then. Second, she ensured everything was cooled to room temperature prior to packaging it for the freezer. She put a layer of wax paper over the top and completely encase the meals in heavy foil. Then she would label on top of the foil with a magic marker. Her instructions to my father and sister was to thaw in the fridge by setting the meals on the bottom shelf in the AM, remove the foil, and then cooking them like they would heat up a plate in the evening.
My mother made stuffed peppers, stuffed cabbage, baked fish, spaghetti with meat sauce, etc. She found that fried dishes like fried chicken and fish did not taste as good when reheated. The baked fish and chicken dishes needed a sauce not to taste dry. Mashed potatoes froze and reheated well, but potato chunks did not.
I remember when she did this. She made over sixty pre-packaged meals. It looked like a stoeffers explosion in her kitchen
Hope this helps!
