Preheat oven to 350 degrees F.

Make Meat Sauce: In a large skillet cook and crumble the ground beef and Italian sausage and season with salt and pepper. Remove most of the grease. Add onions and garlic and cook for a few minutes until onion is translucent. Add all but 1/2 cup of the marinara sauce (reserve 1/2 cup for later) to the mixture and stir to combine. Set aside.

Prepare noodles: Cook Spaghetti according to package instructions, just until “al dente”. Drain, and place hot spaghetti in a large mixing bowl with butter and 1/2 cup reserved marinara sauce and toss to combine.

Make Cheese layer: Combine cream cheese, sour cream and cottage cheese in a bowl and mix well.

Assemble: Pour HALF of the pasta into a 9x13’’ pan. Smooth cheese layer on top. Top with remaining noodles. Add meat sauce on top and smooth into an even layer. Top with mozzarella cheese and parmesan cheese.

Bake for 30-40 minutes or until hot and bubbly. Check it around 20 minutes and if the cheese is browning too quickly, tent a piece of tinfoil over it. Wait at least 15 minutes before cutting and serving, to allow it to set up. Enjoy!
