02 - Bring a large pot of well-salted water to a boil, add spaghetti and cook until just al dente; drain in a colander and set aside.
03 - Heat a large skillet over medium heat, add ground beef, Italian sausage and chopped onion; cook, breaking up the meat, until browned and the onion is softened; drain excess fat.
04 - Add minced garlic to the skillet and cook 1 minute, then stir in marinara sauce, dried basil, dried oregano, salt and pepper; reduce heat and simmer 5 to 7 minutes, then remove from heat.
05 - In a mixing bowl, blend softened cream cheese, ricotta, sour cream, grated Parmesan and chopped parsley until smooth and homogenous.
06 - Arrange half of the cooked spaghetti in an even layer on the bottom of the prepared baking dish.
07 - Evenly spread the cheese mixture over the first spaghetti layer, smoothing to the edges.
08 - Top the cheese mixture with the remaining spaghetti, spreading it to create an even top layer.
09 - Pour the prepared Alfredo sauce over the top spaghetti layer and spread gently to cover evenly.
10 - Spoon the meat sauce evenly over the Alfredo layer, distributing to cover the surface.
11 - Sprinkle shredded mozzarella and the remaining grated Parmesan evenly over the top.
12 - Cover the dish with foil and bake at 350°F for 30 minutes; remove foil and continue baking 10 to 15 minutes more until the cheese is golden and bubbling.
13 - Allow the casserole to rest 10 minutes to set, then slice and serve with desired accompaniments.
