When it comes to cooking in the kitchen, my motto is “Eat all the things.” I'm just kidding. It’s "Work smarter, not harder."

I cook for a small army every day, and I have found that I am most productive when working in batches. This means that if I’m already exerting the energy to get food out and cook it and get dishes dirty, I might as well roll up my sleeves and get to work by making extra food for later.

Think of it as your little BOGO meal. Except maybe it’s MOGO—MAKE ONE, GET ONE. Ha!

Since you’re already making a casserole for your family, you might as well spend a few extra minutes making another one to freeze for later. That way, when life gets crazy and you’re desperate for an easy meal, you’ve already got one in the freezer ready to cook at a moment’s notice. High-fives for everyone!

These casseroles can all be frozen as one whole casserole or as individual portions. Simply bake them, cool them completely, and wrap them tightly in foil. They will keep for up to 3 months.

To reheat the casseroles, cover them loosely with foil in a 350°F oven. It's best to reheat individual portions in the microwave.

TIP! Don't want your casserole dish tied up in the freezer? Line the dish with foil, bake, then cool and freeze the casserole. Once the casserole is solid, lift it out, wrap it in foil, and transfer it to a freezer bag. When ready to bake, unwrap the casserole and transfer it back to the original casserole dish.

Simply Recipes Contributor Nick Evans says, "While I like making my own sauce for this casserole, I prefer using frozen hash browns over fresh. They are a consistent product and easy to use. Plus, frozen hash browns are par-cooked so there is little risk that you will end up with uncooked potato in the center of your casserole."

Simply Recipes Founder Elise Bauer says, "Bread that is a little bit dry will hold up better in the casserole and provide more structure, which is why breakfast casseroles tend to call for "day old" bread. If your bread is fresh or soft, after you cube it, spread it out on a sheet pan and put it in a 200°F oven for 10 to 12 minutes."
