    🔪 How To Make A Million-Dollar Spaghetti Casserole

    One of the best things about this casserole is that it's so easy to prepare, whether you're a seasoned chef or a beginner in the kitchen! Simply take out some measuring cups, measuring spoons, a grater set, a silicone spatula set, a large stockpot, a colander, and a 9x13 baking pan to get started!

    This recipe will yield around 12 hearty servings! There's plenty for a large crowd to enjoy, plus you might even have some tasty leftovers for lunch the next day.

    Cook Pasta & Prepare Casserole Ingredients

    Process image 2 showing added Italian sausage and garlic.
    Process image 3 showing browned Italian sausage.
    Process image 4 showing added tomato sauce and seasoning.
    Process image 5 showing added tomato sauce and seasoning combined with meat.
    Process image 6 showing cottage cheese, cream cheese, and seasoning in a mixing bowl.
    Process image 7 showing added mozzarella cheese
    Process image 8 showing noodles tossed with sauce.
    1. Preheat. Preheat your oven to 350°F (175°C).
    2. Cook pasta. Heat a large pot of salted water to a boil, then add the 16 ounces of spaghetti noodles. Cook pasta according to package instructions minus about 1-2 minutes for the perfect al dente texture.
    3. Drain pasta. Drain into a colander and return the cooked pasta to your pot. Add the first 1 jar or 24 ounces (3 cups) of 48 ounces of spaghetti sauce and combine. Set aside.
    4. Saute. Bring a large skillet to medium heat with 1 tablespoon of olive oil. Once the oil is shimmering, add 1 cup of yellow onion and saute until beginning to soften, about 3 minutes. Add the 1 tablespoon of garlic and continue sauteing for an additional 30 seconds to a minute.
    5. Brown sausage - Add 1-1½ pounds of sweet Italian sausage and the first half of the 1 tablespoon of dried Italian seasoning to the skillet, and cook until browned with no remaining pink. Drain the excess grease. Add the second 1 jar of 48 ounces of spaghetti sauce. Stir to combine and set aside.
    6. Combine cheese. Mash the softened 8 ounces of cream cheese so it will blend well with the additional cheese-filling ingredients. Once smooth, add the 8 ounces of cottage cheese, ¼ cup of sour cream, the first 1 cup of 3 cups of mozzarella, and the remaining half of the 1 tablespoon of dried Italian seasoning. Set aside.

    Build Casserole & Bake

    Process image 11 showing cheese filling layer.
    Process image 12 showing spaghetti and butter layer.
    Process image 13 showing meat sauce layer.
    Process image 14 showing casserole topped with cheese before baking.
    1. Arrange casserole. Arrange half of the ½ cup butter slices in the bottom of your 9x13 baking dish. Place half of the spaghetti mixture in the dish, then evenly distribute the cream cheese mixture on top of the pasta.
    2. Finish adding ingredients. Spread the remaining second half of the spaghetti over the cheese mixture. Then place the remaining butter slices on top. Pour tomato meat sauce evenly over the top layer of spaghetti.
    3. Bake casserole. Top with remaining mozzarella and bake in preheated oven at 350°F (175°C) until casserole is heated through about 40-45 minutes. *I suggest an aluminum foil-lined baking sheet under the pan to catch any drippings.

    This hearty casserole is a filling main course on its own, but you can serve it with a few sides if you'd like! Try my simple Caesar salad or oven garlic bread. Enjoy!

    💭 Angela's Tips & Recipe Notes

    • Use 1 tablespoon of salt per gallon (4 quarts) of water. For more tips on cooking spaghetti to perfection, see my article on how long to cook spaghetti.
    • You can substitute the cottage cheese for equal amounts of ricotta cheese if preferred.
    • If you'd like to add some heat to this casserole dish, feel free to add a pinch of crushed red pepper or use diced jalapenos.
    • While this recipe traditionally calls for mozzarella, you can try using different types of cheese, like cheddar or Monterey Jack, if desired.
    • If you want to add vegetables to this casserole, bell peppers, mushrooms, or spinach can add extra flavor and nutrition!

    🥡 Storing & Reheating

    Once completely cooled, transfer any leftover spaghetti casserole to an airtight container. Store in your refrigerator for up to 3-4 days.

    Freezing Million Dollar Spaghetti Casserole

    After baking, allow your casserole to cool completely. If you plan on freezing individual portions, wrap each piece with plastic wrap and a layer of aluminum foil. Then place them in a heavy-duty freezer bag or freezer-safe containers. Alternatively, you can freeze larger amounts in a freezer-safe baking dish with a lid for up to 3-4 months. When ready to use, thaw in the refrigerator overnight and follow the reheating instructions below.

    Reheating Million Dollar Spaghetti Casserole

    To reheat, preheat your oven to 350°F (175°C) and transfer your leftovers to a baking dish. Cover loosely with a sheet of aluminum foil and cook for about 20-30 minutes or until heated through to your liking. *If the casserole appears dry, add a bit of spaghetti sauce before reheating. Alternatively, you can reheat individual portions in the microwave in 30-second increments.

    ❓ FAQ

    Can I Make This Million Dollar Spaghetti Casserole Vegetarian?

    Absolutely! You can either omit the Italian sausage in the recipe or substitute it with your favorite plant-based protein alternative!

    Can I Prepare Million Dollar Spaghetti Casserole Ahead Of Time?

    Yes! You can prepare this million-dollar spaghetti casserole up to 24 hours ahead of time. Simply follow the recipe instructions up until the point of baking and allow the casserole ingredients to cool completely. Then cover the top of the 9x13 baking pan with plastic wrap and store it in the refrigerator until you are ready to bake and serve.

    Why Did My Million Dollar Spaghetti Casserole Turn Out Dry?

    If your million-dollar spaghetti casserole turned out dry, it be could a result of a few things. Overcooking the spaghetti before assembling the casserole can result in a dry texture. It's important to stop cooking them about 1-2 minutes before the completed time on the package instructions, as they will continue to cook in the oven. Also, if you didn't have enough sauce or the ratio of sauce to spaghetti was off, it could lead to dryness.
