Ingredients You’ll Need

16-ounce package of uncooked spaghetti noodles: The base of the dish; feel free to use whole grain or gluten-free pasta for alternatives.
1 pound ground beef: Ground turkey or a meat substitute works well if you’re looking for a lighter option.
1 small onion, diced: Adds aromatic flavor; white or yellow onions are best for this recipe.
24 ounces marinara sauce: A good quality sauce brings depth to the casserole; homemade or store-bought works great.
19 ounces canned diced tomatoes: Adds texture and flavor; you can substitute with fresh tomatoes if they’re in season.
8 ounces of cream cheese, softened: Provides a rich creaminess; leave it out to soften before mixing for the best consistency.
¼ cup sour cream: Enhances creaminess and tang; Greek yogurt can be an excellent substitute.
1 cup ricotta cheese: This adds a lovely, creamy layer; you can use cottage cheese for a lower-fat option.
2 cups shredded mozzarella cheese: Melts beautifully; a mix of mozzarella and provolone can add extra flavor.
⅔ cup shredded parmesan cheese: Adds a salty, nutty element; fresh grated is always best for maximum flavor.
2 tablespoons fresh parsley (if desired): A sprinkle on top adds a fresh touch, but it can be omitted if you don’t have any on hand.
Salt and pepper to taste: Essential for enhancing the flavor of the dish.

How to Make Million Dollar Spaghetti Casserole

Preheat the Oven: Start by setting your oven to 350 degrees Fahrenheit. While it warms up, spray a 9×13 casserole dish with non-stick cooking spray so your pasta won’t stick.
Cook the Ground Beef: In a large skillet over medium heat, brown 1 pound of ground beef. After draining excess grease, add in the diced onion, cooking until soft, about 3-5 minutes. Then, stir in the 24 ounces of marinara sauce and 19 ounces of diced tomatoes, mixing everything well. Set aside to let the flavors meld.
Cook the Spaghetti: Prepare 16 ounces of uncooked spaghetti noodles according to the package instructions, cooking just until al dente. Drain and rinse the pasta under cool water to stop the cooking process.
Make the Cream Cheese Mixture: In a small bowl, blend together 8 ounces of softened cream cheese, ¼ cup sour cream, and 1 cup ricotta cheese until smooth and creamy.
Layer the Casserole: Pour half of the cooked spaghetti into your prepared baking dish, followed by half of the meat sauce. Spread the cream cheese mixture evenly on top, then layer with the remaining noodles. Pour the rest of the meat sauce over the noodles and smooth it into an even layer.
Add the Cheesy Topping: Finish off by sprinkling 2 cups of shredded mozzarella cheese and ⅔ cup of shredded parmesan cheese evenly over the top.
Bake: Cover the casserole with aluminum foil and place it in the preheated oven. Bake for 30 minutes, then remove the foil and continue cooking for an additional 10 minutes or until the cheese is melty and bubbly.
Cool and Serve: Once out of the oven, let the casserole rest for about 15 minutes to allow it to set. Before serving, garnish with fresh parsley, if desired.

Storing & Reheating

To store leftovers, cool the casserole completely before transferring it to an airtight container. It can last in the refrigerator for up to 3-5 days. If you want to freeze it, wrap it tightly in plastic wrap and then aluminum foil for up to three months. For reheating, simply pop it back in the oven at 350 degrees Fahrenheit for about 20-25 minutes or until warmed through. While the texture may slightly change after freezing, it still keeps all the comforting flavors intact. For a little freshness, consider adding a sprinkle of fresh cheese before reheating.

Chef’s Helpful Tips

If your spaghetti is sticking together, try tossing it with a little olive oil after draining.
Make sure your cream cheese is softened properly to avoid lumps when mixing.
For a more organized layering process, assemble the casserole in individual ramekins for personal servings.
Adjust the cooking time based on your oven, as some can vary in heat intensity.
If you’re feeling adventurous, consider adding veggies like spinach or bell peppers to the meat mixture for an extra nutritional boost.

Whether you’re feeding a family of eight or prepping for a potluck, this dish is bound to please. Don’t hesitate to play with the ingredients, try new variations, or even serve it alongside a crisp salad or garlic bread. Enjoy the process of creating this delightful meal, and savor every cheesy, hearty bite!
