I don’t think it gets any better than living in New England in the Fall, staring at the colorful leaves outside, and cooking up a creamy casserole in your kitchen while the football game is on.

MY LATEST VIDEOS

Ever since I learned of this awesome chicken noodle soup recipe that uses Reames Frozen Egg Noodles, I started using them in my cooking whenever possible, and knew they’d be perfect for my creamy casserole.

They have all the goodness of homemade noodles without the hassle. I love how thick they are – they hold up wonderfully in casseroles, whereas regular dried egg noodles fall apart far more easily. The taste sets them apart too, you can just tell your family you made them from scratch and no one would ever know! 😉

The Best Cheese for Casseroles

Cheese is always creamier and melts better if you grate 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.

It’s best to wrap the casserole in foil, then place it in a labeled freezer bag with the date.

When ready to reheat, let the casserole defrost in the fridge for 24 hours, then reheat at 350 degrees, 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 instead, simply 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!
