Ingredients for Baked Spaghetti and Meatballs

- Spaghetti. One pound of your favorite brand of traditional spaghetti.
- Olive oil. This will make sure the pasta does not stick to the large skillet or baking dish. You can also use cooking spray to spray the baking dish.
- Mozzarella Cheese. Shredded so it is easy to sprinkle over the top of the casserole.
- Italian Meatballs. One bag of your family's favorite meatballs. You can keep them frozen or thaw them. You don't have to have all the meatball ingredients on hand to make your own, buy the bags at the grocery store!
- Pasta Sauce. One 23 ounces jar of your favorite marinara sauce. If you are making your own tomato sauce, you will need 3-4 cups of marinara sauce.
- Parmesan. If you have fresh grated parmesan cheese, that's best, but whatever type you have is great!
