Italian Chicken Spaghetti is a twist on the classic cheesy chicken spaghetti casserole most are familiar with. This recipe has a red sauce, like what you would find in a traditional spaghetti dish. This dish is super flavorful and simple to make. This may become your family's new favorite casserole dish.

I love the convenience of casserole dishes. Having everything in one dish that is easy to make, and meal prep friendly, makes busy days much easier. Plus, there are almost always leftovers for another night. This is especially true for pasta casseroles like this one. It's hard to make small portions, so you are usually left with leftovers. Which are easy to reheat in the oven, on the stovetop or in the microwave.

I usually serve this chicken spaghetti with garlic bread on the side. What's pasta without garlic bread, right? Since there are english peas and tomatoes in the casserole, I typically don't make any other side dish.

Use leftover roasted chicken.
Add or substitute veggies. Zucchini, summer squash, mushrooms and spinach are all great in this recipe.

u003cstrongu003eHow to Freeze Italian Chicken Spaghettiu003c/strongu003e

You can freeze the casserole two different ways. In a casserole dish or in a gallon freezer bag. I recommend freezing it in a casserole dish. It makes it easier when you decide to cook it. All you will need to do is thaw overnight then pop the dish in the oven.

Freezing the Casserole in a Freezer Bag

After mixing all of the ingredients together, allow to cool completely, then place in a gallon freezer bag. Lay the bag flat in the freezer. This will take up less space in the freezer.

When you are ready to cook the casserole, thaw in the refrigerator overnight. Place in a lightly greased baking dish and top with the remaining cheese. Wrap with foil and continue with the baking instructions.

Freezing the Casserole in a Baking Dish

Follow the directions entirely, until you get to baking the casserole. Instead, allow the casserole to cool completely (un-covered). Once the casserole has completely cooled, wrap in plastic wrap and foil. Place in the freezer until needed.

Thaw the casserole in the refrigerator overnight. Remove the plastic wrap, place the foil back on and continue with the baking instructions.

You can also freeze your leftovers!
