Baked Spaghetti Casserole with Meatballs

This baked spaghetti casserole recipe starts with cooked spaghetti noodles.  The sauce layer is your favorite jarred or homemade marinara (this is my favorite 30 minute marinara recipe) doctored up just a little bit.  The cheese mixture includes ricotta cheese, sour cream, garlic, parsley and Italian seasoning. Then it’s topped with a layer of meatballs and a blanket of mozzarella.

One of my favorite things about this spaghetti casserole bake is I can easily adjust the amount.  Many times, I end up doubling the recipe and freezing one so that I have an extra spaghetti meatball casserole for another meal.  This is a huge time-saver on busy nights when we’re running around to activities.

Other times, I will halve the recipe and make smaller portions to share with my mother in law.  I simply cut the ingredients in half (you can even adjust the servings in my recipe card below to change the amounts of the ingredients) and layer them in a disposable loaf pan.

Or make a full batch, and split the ingredients between two loaf pans.  I just low how flexible this easy baked spaghetti casserole is.

For the meatball layer in this casserole, I simply sliced each meatball in half and arranged them in an even layer on top of the spaghetti and cheese layers.

How to Make This Spaghetti Casserole Recipe

Begin by placing a layer of cooked spaghetti noodles in a baking dish.  Then top it with the cheese mixture, followed by another spaghetti layer.

Next, place an even layer of meatballs on top of the casserole and cover it with slices of mozzarella cheese.  You can also use shredded mozzarella if you prefer.

This recipe is often referred to as Million Dollar Spaghetti Casserole and it’s easy to see why – it taste like a million bucks!
