A cozy baked spaghetti casserole with creamy cheese layers, hearty meat sauce, and a golden, bubbly finish.
The Comfort-Food Classic, Made a Little Smarter
Million Dollar Spaghetti earns its name from the rich, layered combination of pasta, savory meat sauce, and a creamy cheese filling that bakes into something far more indulgent than an ordinary weeknight spaghetti. This version keeps that familiar casserole character while using lean ground beef, a measured amount of cheese, and a balanced tomato sauce so the dish stays hearty without becoming overwhelmingly heavy. The cream cheese, cottage cheese, and mozzarella create the signature creamy center, while the meat sauce adds plenty of savory depth. It is an excellent make-ahead dinner for family meals, potlucks, or nights when you want leftovers that reheat well. The recipe has not been independently human-tested by The Healthy Plate Lab; it is developed from established cooking methods and standard recipe ratios, so ingredient brands and individual ovens may affect the final result.

Time Breakdown & Servings
Prep Time: 25 minutes
Cook Time: 40 minutes
Total Time: 1 hour 5 minutes
Servings: 8
Ingredients You’ll Need
- 340 g (12 oz) spaghetti
- 450 g (1 lb) lean ground beef, preferably 90–93% lean
- 1 tablespoon olive oil
- 1 small yellow onion, finely diced (about 120 g)
- 3 garlic cloves, minced
- 700 g (24 oz) marinara or tomato-basil pasta sauce
- 1 teaspoon Italian seasoning
- 1/2 teaspoon salt, divided
- 1/4 teaspoon black pepper
- 225 g (8 oz) low-fat cottage cheese
- 115 g (4 oz) reduced-fat cream cheese, softened
- 1 large egg
- 60 g (1/2 cup) grated Parmesan cheese, divided
- 150 g (1 1/2 cups) shredded part-skim mozzarella, divided
- 1 tablespoon chopped fresh parsley, optional
Ingredient Notes & Practical Substitutions
- Spaghetti. Whole-wheat spaghetti works well if you prefer more fiber. Cook it just until al dente because it will continue cooking in the oven.
- Ground beef. Lean ground turkey can replace the beef. If using very lean meat, keep the olive oil so the sauce does not become dry.
- Cottage cheese. Small-curd cottage cheese blends smoothly into the filling. Ricotta can be substituted for a more traditional baked-pasta texture.
- Cream cheese. Reduced-fat cream cheese keeps the filling creamy with less fat. Full-fat cream cheese also works if that is what you have.
- Mozzarella. Part-skim mozzarella gives a good melt without making the casserole excessively greasy. Provolone can be used for a slightly sharper flavor.

Step-by-Step Instructions
- Cook the spaghetti.. Bring a large pot of salted water to a boil. Cook the 340 g spaghetti until just al dente according to the package directions. Reserve about 120 ml (1/2 cup) pasta water, then drain. Do not rinse.
- Build the meat sauce.. Heat 1 tablespoon olive oil in a large skillet over medium heat. Add the 120 g diced onion and cook for 3–4 minutes. Add 3 minced garlic cloves and cook for 30 seconds.
- Brown the beef.. Add 450 g lean ground beef. Cook for 6–8 minutes, breaking it into small pieces, until browned and cooked through. Drain excess fat if needed.
- Season and simmer.. Stir in 700 g marinara sauce, 1 teaspoon Italian seasoning, 1/4 teaspoon salt, and 1/4 teaspoon black pepper. Simmer gently for 5 minutes. If the sauce seems very thick, loosen it with a splash of the reserved pasta water.
- Make the creamy filling.. In a bowl, mix 225 g cottage cheese, 115 g softened cream cheese, 1 large egg, and 30 g (1/4 cup) Parmesan until evenly combined.
- Combine the pasta.. Toss the drained spaghetti with about half of the meat sauce, adding a little reserved pasta water if necessary to coat the strands. The pasta should be moist but not soupy.
- Layer the casserole.. Lightly grease a 9 × 13-inch baking dish. Spread half of the spaghetti mixture across the bottom. Spoon the entire creamy cheese mixture over it and spread gently. Add the remaining spaghetti.
- Add the topping.. Spoon the remaining meat sauce over the spaghetti. Sprinkle with the remaining 30 g Parmesan and 150 g shredded mozzarella.
- Bake until bubbly.. Cover loosely with foil and bake at 190°C (375°F) for 25 minutes. Remove the foil and bake for another 10–15 minutes, until the cheese is melted and lightly golden.
- Rest and serve.. Let the casserole rest for 10 minutes before slicing. Finish with 1 tablespoon chopped parsley if using.
Expert Tips for Best Results
- Cook the pasta al dente. Slightly firm pasta gives the casserole enough structure after baking.
- Do not overfill the cheese layer. Spread the creamy mixture gently so it stays distinct between the spaghetti layers.
- Use a flavorful marinara. Since the sauce carries much of the tomato flavor, choose one you already enjoy.
- Cover before uncovering. Foil keeps the casserole from drying out while the center heats through; uncovering at the end gives the mozzarella a better finish.
- Rest before cutting. Ten minutes allows the cheese layer to settle, making cleaner portions.
Common Mistakes To Avoid
- Overcooking the spaghetti. Mushy pasta becomes soft and difficult to portion after baking.
- Using a watery sauce. Excess liquid can make the casserole loose. Simmer thin sauce briefly before layering.
- Skipping the rest time. Cutting immediately can cause the creamy filling to spread instead of staying layered.
- Overbrowning the cheese. If the top is darkening too quickly, loosely cover the dish again.
- Under-seasoning the components. Taste the meat sauce before assembling so the finished casserole has enough savory flavor.
Recipe Variations
- Turkey million-dollar spaghetti. Replace the lean beef with lean ground turkey.
- Vegetable-packed version. Add finely diced bell pepper, mushrooms, or spinach to the meat sauce.
- Extra-herby version. Add fresh basil or oregano to the tomato sauce before layering.
- Spicy version. Stir a small amount of crushed red pepper into the meat sauce.
- Chicken version. Use cooked shredded chicken in place of ground beef and pair it with a tomato sauce seasoned with Italian herbs.
