Million Dollar Spaghetti is the ultimate comfort food casserole that never fails to impress a hungry crowd. Creamy alfredo-coated noodles are topped with rich meat sauce and a generous blanket of gooey cheese for a dinner that feels both decadent and effortless. This is the dish my friends beg me to bring to every potluck and family gathering.
I love how this dinner brings everyone to the table without complaint. The first time I made it for extended family, there was not a single bite left and even the picky eaters wanted seconds.
Ingredients
- Spaghetti noodles: Choose a high quality brand and cook until al dente for the best texture
- Ground beef: Pick lean ground beef to avoid excess grease and get a hearty flavor
- Onion and green bell pepper: Fresh diced onion and bell pepper add sweetness and depth to the meat sauce
- Cajun seasoning Garlic powder Onion powder Dried Italian seasoning: Essential spices for rich, savory notes in every bite
- Marinara sauce: Use your favorite jarred brand or homemade, just make sure it has a bold tomato flavor
- Unsalted butter: Needed for the alfredo layer so you can control the saltiness
- Garlic: Fresh minced garlic creates a fragrant base for the creamy sauce
- Heavy cream: Makes the alfredo luxuriously thick
- Shredded parmesan cheese: Adds sharp, nutty flavor to the sauce and the topping
- Kosher salt and black pepper: Enhances all the other flavors
- Shredded mozzarella cheese: Melts beautifully for that gooey golden top
- Dried parsley flakes: For a pop of color if you want to garnish at the end
Step-by-Step Instructions
- Prep and Cook Spaghetti:
- Boil spaghetti noodles in salted water until just al dente. Drain and set aside so they do not overcook in the oven.
- Sauté and Season Meat:
- In a large skillet, brown ground beef over medium-high heat. Add diced onion, bell pepper, cajun seasoning, garlic powder, onion powder, and dried Italian seasoning. Fully cook the beef and soften the veggies for about ten minutes, which builds the hearty foundation.
- Simmer Meat Sauce:
- Drain excess grease. Stir marinara sauce into the beef mixture. Lower the heat and gently simmer for fifteen minutes, allowing flavors to deepen and thicken. Stir occasionally so nothing sticks.
- Make Alfredo Sauce:
- While the meat sauce simmers, melt butter in a large pot over medium heat until just bubbling. Add minced garlic and sauté for thirty seconds to unlock its fragrance. Pour in heavy cream and sprinkle with shredded parmesan cheese, salt, and pepper. Stir constantly until the cheese melts and the sauce thickens slightly for a silky coating.
- Coat Spaghetti with Alfredo:
- Add cooked spaghetti to the alfredo sauce. Toss carefully to evenly coat all noodles. This creates a creamy base layer that holds up to baking.
- Layer and Assemble:
- Pour the alfredo-coated spaghetti into your prepared baking dish. Spread it out evenly. Carefully layer the savory meat sauce over the top without mixing.
- Add Cheese Topping:
- Sprinkle shredded mozzarella and a little extra parmesan cheese all over the top. This step ensures a golden bubbly finish after baking.
- Bake and Serve:
- Place in the oven uncovered and bake for fifteen minutes until cheese is melted and edges are bubbling. Garnish with dried parsley if you like a splash of green. Serve hot and watch it disappear.

My absolute favorite part of this recipe is how the parmesan in the alfredo sauce brings everything together. My kids always say the cheesy top is the best bite and love helping to sprinkle it on before baking.
Storage Tips
Keep leftover spaghetti covered in the refrigerator for up to four days. Reheat slices in the microwave or cover with foil and warm gently in the oven at three hundred fifty degrees until heated through. This casserole also freezes well. Let it cool completely before wrapping tightly and freezing for up to two months. Thaw in the fridge overnight before reheating.
Ingredient Substitutions
Swap ground beef for ground turkey or Italian sausage for a lighter or bolder option. Gluten free spaghetti noodles work well if needed—just be sure not to overcook. If you want extra veggies, try adding finely chopped mushrooms or spinach to the meat mixture for more flavor and color.
