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.

    This is such a wonderful recipe! I love that the recipe can be halved. Since my husband and I are “almost” empty-nesters, we don’t need to make as much as we used to. So happy it’s freezer friendly too!

  5. I tend to put dinners in my freezer and then forget about them… But this I would NOT forget about ever! In fact, it might not even make sense to freeze it because I’d just be thawing it the next day LOL. Seriously though, it looks fabulous- also the perfect meal to bring to friends who have just had a baby!
