How do you know when breakfast casserole is done? Just stick a knife into the center of your egg casserole recipe after 55 minutes of baking. If it comes out clean, your baked egg casserole is ready!

Pre-cook the veggies. Veggies are naturally watery. As they cook, they release that moisture. If they only cook in the casserole, all that extra moisture will also be IN your casserole.

Myth: You shouldn't put hot foods in the refrigerator.

Perishable foods should be put in a refrigerator that is 40 degrees or below within 2 hours of preparation. If you leave food out to cool and forget about it after 2 hours, throw it away.

Always Drain Your Meat To Avoid Rubbery Eggs

But no worries, this doesn't mean you have to forgo meat in your egg casserole altogether. The fix is simple and doesn't require much extra effort. The hack that can help preserve the texture of your eggs is to always drain meat before adding it to a casserole.

Plan 15 to 20 minutes additional heating time for the refrigerated cold casserole. Heat until it's hot and steamy throughout (165 °F as measured by a food thermometer).

High heat cooks the outside faster than the inside, leaving the middle uncooked. Reducing the temperature distributes heat more evenly, allowing the middle to cook through. If uncooked in the center then cover at the same temperature and ad 15 minutes before checking again.

Whisk together equal parts cornstarch and cold water in a small bowl. Use one tablespoon of cornstarch per cup of liquid you would like to thicken. Stir out all the lumps. A few minutes before your casserole is done, add it a little at a time until you are happy with the thickness.

The answer depends on what's in it. Casseroles with raw protein (meat, poultry, seafood) should be completely cooked before freezing. However dishes with pre-cooked meats or no meat are fine to go in the freezer uncooked.

Unless food will be frozen, it's safest and will provide the best quality product to start preparing most perishable foods no more than a day before a meal. For example, assemble a vegetable casserole a day in advance, refrigerate and then bake the day of your dinner.

Cool to room temperature. Wrap tightly with foil or plastic wrap and refrigerate overnight, then reheat in a 375 F oven for 30 minutes the next morning until the casserole is browned and heated through.

Let your cooked casserole cool to room temp for about an hour after cooking, then cover and chill in the fridge overnight. Never put a hot casserole (or anything else for that matter) into your fridge or freezer; you will raise the temperature of your appliance which can be unsafe for your food.

How long does it take a refrigerated casserole to come to room temp? Depending on the size of the dish and the density of its contents, it takes about an hour for to come up to room temperature. Add more time for a larger pan or one with dense contents.
