Can you freeze casseroles?
USDA FoodKeeper gives no freezer time for casseroles. USDA's leftovers guidance says you can reheat a frozen casserole without thawing it first. It takes longer, so cover it and check that the middle reaches 165°F.
How to store casseroles
Cut what is left into portions or move it to shallow containers so it cools fast. A full, deep dish takes a long time to get cold in the middle.
How long can casseroles sit out?
No more than 2 hours at room temperature, or 1 hour when it is above 90°F, such as at a summer picnic. After that, USDA says to throw it out.

How to tell if casseroles have gone bad
Go by the days, not by the smell. The germs that cause food poisoning usually do not change how food looks, smells or tastes, so food past its time can seem fine and still make you sick. Mold, a sour smell or a slimy feel mean it has spoiled, but food without them is not safe just because it seems fine. Never taste food to check it. When in doubt, throw it out.
How to reheat casseroles
Heat leftovers until the middle reaches 165°F on a food thermometer, and bring soups, sauces and gravy to a rolling boil. Cover the food while it heats so it stays moist and heats all the way through. In a microwave, stir or turn it halfway. You can reheat frozen leftovers without thawing them first. It takes longer.
