If you've ever had classic chicken spaghetti, you know it's usually creamy, cheesy, and totally comforting. This Italian Chicken Spaghetti is a little different, it's made with a simple, flavorful red sauce instead. Think of it like a mash-up between your favorite baked spaghetti and a cozy chicken casserole.

It's one of those easy, from-scratch dinners I turn to when I want something hearty but don't want to stand over the stove all evening. The sauce comes together quickly, then it all gets tossed with spaghetti, English peas, and chicken, topped with cheese, and baked until bubbly and golden.

I love this one because it's freezer-friendly, make-ahead friendly, and always a hit with my family. If you're looking for something a little different for spaghetti night but still want those classic flavors, this is it.

I love the convenience of casserole dishes. Having everything in one dish that is easy to make. 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.

Freezer Tips

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.

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.

Casserole 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.
