# How to Make It:
01 - Preheat oven to 350°F. Lightly grease a 9x13-inch baking dish with oil or nonstick spray.
02 - Bring a large pot of salted water to a rolling boil. Add spaghetti and cook until just al dente according to package instructions. Drain 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 translucent. Drain off excess fat. Add minced garlic and cook 1 minute until fragrant.
04 - Stir in marinara sauce, dried basil, dried oregano, salt and black pepper. Reduce heat and simmer gently 5–7 minutes to meld flavors, then remove from heat.
05 - In a mixing bowl, beat together softened cream cheese, ricotta, sour cream, grated Parmesan and chopped parsley until smooth and homogenous.
06 - Spread half of the cooked spaghetti in an even layer across the bottom of the prepared baking dish.
07 - Spoon and spread the cheese mixture evenly over the bottom spaghetti layer, smoothing to the edges.
08 - Arrange the remaining spaghetti over the cheese layer, pressing lightly to form an even surface.
09 - Pour the prepared Alfredo sauce over the upper pasta layer and spread to cover. Spoon the meat sauce evenly over the Alfredo layer.
10 - Distribute shredded mozzarella and the remaining grated Parmesan evenly over the assembled layers.
11 - Cover the dish tightly with foil and bake for 30 minutes to heat through and marry flavors.
12 - Remove the foil and return to the oven for 10–15 minutes more, or until the cheese is golden and bubbling.
13 - Allow the casserole to rest 10 minutes out of the oven to set, then slice into portions and serve.
