🥘 Ingredients

• Pasta: Any long pasta will work in this dish. Spaghetti or thin spaghetti pasta noodles are my preferred picks. However, smaller pastas like penne, rigatoni, farfalle (bowtie pasta), shells or whatever you have on hand will work in a pinch!
• Sauce: Homemade spaghetti sauce, arrabbiata sauce, or marinara are all wonderful, but for the sake of time your favorite store bought sauces can also be used. Spice up commercial sauces to taste like homemade by adding fresh Italian herbs like basil and oregano or using my spaghetti seasoning. One of my secrets for amazing spaghetti sauce (and pizza sauce) is to grind up dried fennel seeds and add them to any store bought or homemade sauce.
• Meatballs: This is one component that I always prefer to use homemade meatballs. Meatballs can be made ahead of time and frozen for serving later, or cooked up fresh for a spaghetti dinner and/or this easy casserole. I like to use mild or sweet Italian sausage for my Italian meatballs, but sausage can also be combined with ground beef or the meatballs can be made with hamburger meat only.
• Cheese: Mozzarella and Parmesan cheeses are a must have for this tasty dinner! Mix freshly grated mozzarella into the spaghetti and sauce layers, or add in between layers. A layer of Ricotta or mascarpone cheese can also be added between spaghetti layers. You also can make your cream cheese or cottage cheese 'Italian-ey' with added fresh basil for a substitution.
• Vegetable Stir-Ins: (Optional) Add some more vegetables to this saucy dish! Mushrooms are a family favorite, plus everyone likes some zucchini or red peppers and my daughter requests olives on occasion.

🔪 Step-by-Step Instructions

1. Start with preheating your oven to 350ºF (175ºC). Next, grease or spray your casserole dish with non-stick cooking spray while you cook your pasta. Start your pasta in a large pot or Dutch oven with salted water. Boil and cook the pasta per the package instructions, minus 2 minutes for an al denté texture. (Since the pasta will cook while baking too.)
2. Drain the cooked pasta without rinsing and return it to your stock pot or Dutch oven. Toss to coat the pasta with a tablespoon of extra virgin olive oil and a teaspoon of Italian seasoning.
3. Add the marinara or spaghetti sauce, the fully cooked meatballs ( see below for homemade beef meatballs instructions ), and a half cup portion of the grated mozzarella cheese. Toss to combine thoroughly.
4. Transfer the combined casserole ingredients into your prepared baking dish, spreading the contents evenly. *To make your casserole look like the photo. (Yum!) Reserve several meatballs to place on the top of the pasta. Cut fresh, baby mozzarella balls into halves and place between the meatballs. (Instead of topping the casserole with the remaining ½ cup portion of grated mozzarella after 30 minutes of baking time.) Bake for 35 minutes.
5. Bake at 350ºF (175ºC) for 30 minutes, then remove from the oven and top with the remaining half cup portion of grated mozzarella cheese.
6. Return to the oven and bake for an additional 10 minutes, or until the cheese is fully melted and the casserole bubbles slightly around the edges.
7. Remove from the oven and serve immediately. Garnish with freshly grated Parmesan cheese, young basil leaves, chopped fresh basil or parsley, and/or Italian seasoning.

Bake Your Homemade Meatballs

1. To make your homemade meatballs you can use one pound of beef as noted in the recipe below. You can also use a combination of beef and ground pork or Italian sausage, all ground pork, or all Italian sausage. (I like mild or sweet Italian sausage for meatballs.)
2. Combine all of your meatball ingredients in a large mixing bowl: ground beef, beaten egg, Parmesan cheese, breadcrumbs or Panko, garlic powder, onion powder, salt and pepper. Use clean hands or a large mixing spoon to combine thoroughly.
3. Roll out your meatballs into roughly 1 ¼ to 1 ½ inch sized meatballs. Then transfer to your casserole or baking dish that has been coated with one tablespoon of extra virgin olive oil. Bake at 350ºF (175ºC) for 20 minutes, or until the meatballs are no longer pink inside.

Remove the meatballs from the oven when done. Then combine with pasta and sauce as directed above and in the recipe card below. Enjoy!

💭 Angela's Tips & Recipe Notes

• Fully cooked meatballs should have an internal temperature of 165ºF (74ºC) as read by your digital meat thermometer. This is more important in the case of a casserole that you are putting together to bake later.
• Store bought meatballs, a can or jar of spaghetti sauce, and some boiled pasta work in a pinch for a freshly made version that comes together ALMOST as quickly as leftovers!
• Make ahead and bake later, or freeze! This casserole is a great way to use leftovers, but is also a great dish for freezing.
