I’m not sure I would do so well in a world without casseroles. They’re just so creamy, usually freeze well, (if you actually have leftovers), and they’re easy to customize and throw together.

Let’s get into the deets!

The Best Cheese for Casseroles

Cheese is always creamier and melts better if you shred it fresh at home, as opposed to buying it pre-shredded.

Low moisture mozzarella melts the best and is what you’ll want to use in this recipe.

Can You Freeze Leftover Casserole?

• Reames Frozen Egg Noodles hold up well when frozen. Creamy casseroles such as this won’t have quite the same flavor or consistency when reheated, but freezing is definitely a fine way to make use of leftovers.
• When ready to reheat, let the casserole defrost in the fridge for 24 hours, then reheat at 350°, covered, for about 20 minutes.
• Frozen casserole is best if used within 3 months of freezing.

Using Rotisserie Chicken in Casseroles

I love the convenience of using rotisserie chicken in casseroles because it eliminates the steps in having to cook the chicken, and rotisserie chicken packs a ton of flavor.

If you do happen to cook your own chicken:

• Add a tablespoon of vegetable oil to your skillet and sear the chicken on each side before you cook the onions.
• Remove the chicken and proceed with cooking the onions afterwards. The benefit of doing it this way is that the seared chicken adds even more flavor to the pan which transfers into the casserole!
