Ingredients
For this indulgent Million Dollar Spaghetti Casserole, you will need:

- Salt, for boiling, enhancing the overall flavor of the pasta.
- 1 lb lean ground beef, packed with juicy, meaty goodness that’s sure to satisfy.
- 1 (24 oz) jar marinara sauce, offering a rich, tangy flavor that elevates the dish.
- 1 tsp Italian seasoning, bringing a delightful herbal aroma that will fill your kitchen.
- 1/2 tsp garlic powder, lending a savory kick to the sauce.
- 8 oz cream cheese, softened, which adds a creamy, rich texture that melds beautifully with the pasta.
- 1 cup sour cream, providing a tangy contrast that balances the richness.
- 1/2 cup grated Parmesan cheese, one of the key ingredients for a savory, cheesy layer.
- 2 cups shredded mozzarella cheese, ensuring a gooey, melty finish with that iconic cheese pull.
Step-by-Step Directions

Bring a large pot of salted water to a boil. Add spaghetti and cook until just shy of al dente. Drain and set aside to keep it from becoming overly soft.
In a skillet over medium-high heat, cook the ground beef until browned, which should take approximately 5-7 minutes. Drain any excess fat to keep the dish flavorful but not greasy.
Stir in the marinara sauce, Italian seasoning, and garlic powder. Allow it to simmer for about 5 minutes, letting those aromatic flavors deepen.
In a large bowl, combine cream cheese, sour cream, and Parmesan cheese until smooth. This creamy blend will coat the hot spaghetti perfectly, ensuring every bite is rich and delicious.
Lightly grease a 9×13-inch baking dish. Layer half of the meat sauce on the bottom, followed by the creamy spaghetti mixture, and then top it off with the remaining meat sauce.
Preheat the oven to 350°F (175°C) and sprinkle the shredded mozzarella cheese generously on top for a gooey finish.
Bake uncovered for about 30 minutes or until bubbly and golden. You’ll know it’s ready when the cheese is melted and the edges are perfectly browned.
Allow the casserole to rest for 10 minutes before serving, giving it time to set for the ultimate serving experience.
Tips & Tricks
For an extra depth of flavor, consider adding sautéed onions or bell peppers to the ground beef while cooking. You can also sprinkle some fresh basil or oregano on top before serving to enhance the dish’s aroma. Additionally, using freshly grated cheeses will elevate the texture and flavor profile.
