Cook the noodles according to package directions, then drain and add the butter, tossing to coat. Stir in one jar of marinara sauce.
While the noodles are cooking, heat a large skillet over medium heat. Cook the sausage, beef, onion and garlic until the meat is no longer pink.
Add the Italian seasoning and one jar of marinara sauce, stirring to combine. Remove from heat and set aside.
In a medium sized bowl, stir to combine the cottage cheese, cream cheese, heavy whipping cream, egg and 1 cup of mozzarella.
Preheat the oven to 350°F and spray a 9x13 inch pan with non-stick cooking spray.
Place a couple tablespoons of the meat sauce into the bottom of the pan, then layer the pasta over the meat. Top with more meat sauce, then spread the cottage cheese sauce mixture over the meat.
Place in the oven and bake for 20 minutes. Remove and top with remaining cheese. Place back in the oven and bake for 10 minutes more.
If the cheese hasn’t browned enough, you can turn on the broiler and brown the cheese for a couple of minutes.
Remove and allow to sit for 10 minutes before serving. Sprinkle with parsley and serve!
