Ingredients

  • 16 Ounces spaghetti
  • 6 Tablespoons butter melted
  • 36 Ounces marinara sauce
  • 1 Pound lean ground beef
  • ½ Pound Italian sausage
  • 8 Ounces cream cheese softened
  • 1 Cup cottage cheese
  • ½ Cup sour cream
  • 2 Cups mozzarella cheese shredded
  • ½ Cup Parmesan cheese grated
  • 2 Teaspoons Italian seasoning
  • 1 Teaspoon garlic powder
  • ½ Teaspoon onion powder
  • ½ Teaspoon salt
  • ¼ Teaspoon black pepper
  • 2 Tablespoons chopped fresh parsley optional

Instructions

Preheat the Oven

  • Preheat the oven to 350°F.
  • Grease a 9 x 13-inch baking dish with 4 Tablespoons of the melted butter.

Cook the Spaghetti

  • Bring a large pot of salted water to a boil.
  • Cook the spaghetti following the package directions. Drain well.
  • I recommend that you cook your spaghetti to al dente, because it's going to soften some more while baking later.
  • Return the spaghetti to the pot and toss with the remaining 2 Tablespoons of melted butter and about one-third of the marinara sauce until evenly coated.

Prepare the Meat Layer

  • Meanwhile, cook the ground beef and Italian sausage in a large skillet over medium heat until browned and fully done, breaking the meat into crumbles as it cooks.
  • Don't forget to drain any excess grease to prevent a greasy casserole.
  • Stir the remaining marinara sauce, Italian seasoning, garlic powder, onion powder, salt, and black pepper into the meat.
  • Simmer for 10 minutes.

Prepare the Cheese Layer

  • In a large bowl, combine the cream cheese, cottage cheese, sour cream, ¼ Cup Parmesan cheese and ½ Cup mozzarella until smooth.

Assemble the Casserole

  • Spread half of the spaghetti into the prepared baking dish.
  • Evenly spread the cheese mixture over the spaghetti. Sprinkle ½ Cup mozzarella over the cheese mixture.
  • Top with the remaining spaghetti.
  • Pour the meat sauce evenly over the top.
  • Sprinkle with the remaining 1 Cup mozzarella and ¼ Cup Parmesan.

Bake the Million Dollar Spaghetti

  • Cover loosely with foil and bake for 30 minutes.
  • Remove the foil and continue baking for 15 minutes, or until the cheese is melted, bubbly, and lightly golden.
  • Sprinkle the finished dish with chopped fresh parsley, if liked.
  • Let the casserole rest for 10 minutes before slicing and serving - it will hold together better!

Notes

Cook the spaghetti to al dente: Take the pasta off the heat as soon as it reaches al dente. Softer spaghetti can get too soft during the long bake.
Soften the cream cheese completely: I find room temperature cream cheese much easier to mix smoothly with the cottage cheese and sour cream.
Let it rest: Give the casserole a full ten-minute rest before cutting into it. I find the portions hold together much better if I don’t rush this part.
