How to Make Million Dollar Spaghetti
Step 1: Preheat and Prepare
Preheat the oven to 350°F. Spray a 9×13-inch baking dish with cooking spray and set it aside. Cook the spaghetti noodles according to the package directions until they reach an al dente texture.
Step 2: Cook the Beef Mixture
In a large skillet over medium-high heat, add the ground beef, onion, green bell pepper, Cajun seasoning, garlic powder, onion powder, and Italian seasoning. Cook until the beef is no longer pink and the vegetables have softened, about 10 minutes. Drain any excess grease, stir in the marinara sauce, and let it simmer for 15 minutes.
Step 3: Prepare the Alfredo Sauce
For the alfredo sauce, melt butter in a large pot over medium heat. Add minced garlic and cook for about 30 seconds until fragrant. Stir in the heavy cream, parmesan cheese, salt, and pepper; continue cooking until the cheese melts and the sauce thickens.
Step 4: Combine and Assemble
Combine the cooked spaghetti with the alfredo sauce, thoroughly coating the noodles. Pour this mixture into the prepared baking dish, then top with the meat sauce. Sprinkle shredded mozzarella and additional parmesan cheese over the top.
Step 5: Bake to Perfection
Bake for 15 minutes until the cheese is melted and bubbly. If desired, garnish with dried parsley flakes before serving. Enjoy your delicious creation!

Pro Tips from My Kitchen
✓ Drain the Meat – Make sure to drain the excess grease from the beef after cooking. This helps keep your dish from becoming greasy and allows the flavors to shine through.
✓ Test the Noodles – Cook the spaghetti until al dente for the best texture. Overcooked noodles can become mushy once baked.
✓ Fresh Ingredients Matter – Use fresh garlic instead of garlic powder for a more intense flavor in the alfredo sauce. Fresh ingredients elevate any dish.
✓ Mix Sauces Gently – When combining spaghetti and the alfredo sauce, toss gently to avoid breaking the noodles. This helps maintain their integrity while coating them evenly.
✓ Let it Rest – Allow the baked spaghetti to rest for a few minutes before serving. This helps the layers set, allowing for perfect serving portions.
What Makes This Recipe Work
- The combination of creamy alfredo and rich marinara sauce creates a delightful contrast of flavors that keeps every bite exciting. The sauces meld beautifully in the oven, making the dish even more flavorful as they cook together.
- Using a combination of cheeses not only gives great flavor but also ensures a perfect gooey texture on top. The melted mozzarella and parmesan create that classic baked pasta experience that we all love.
- The selection of spices and sautéed vegetables enhances the overall taste profile, giving depth to the layers. This attention to seasoning helps the dish stand out, turning a simple spaghetti bake into a memorable meal.
Frequently Asked Questions About Million Dollar Spaghetti
