I would like to cook a reasonable amount of food, such as 6 or 8
servings of a casserole or chicken divan or beef stroganoff, and then
freeze each individual serving so that it can be easily heated in a
microwave. What should I freeze the food in? plastic wrap? ziploc
bags? How long can I keep the food in the freezer? How long do you
think I should heat a serving in the microwave so that it is warmed
thoroughly but not dried out? I am hopeful that an experienced cook
will help a beginner like me. Thanks.

Greetings,
There are plastic containers that are freezer-to-microwave, look like
Tupperware, who may have such.  Heating in a microwave is dependent on
weight and the temperature of the food, obviously longer for frozen
food than for such at room temperature.  Your pamphlet for the
microwave will probably have some instructions.

This is just a free comment, not an "answer" to your question.

Good luck, Myoarin

Hi Myoarin,

I appreciate your ideas. I'm going to experiment with Glad Press'n'Seal.

Thanks, SusieQ123
