# Method:
01 - Preheat oven to 350°F. Lightly grease a 9x13-inch baking dish.

03 - In a large skillet over medium-high heat, brown ground beef and Italian sausage, breaking up meat with a spoon. Drain excess fat.
04 - Add diced onion and minced garlic to meat mixture. Sauté until onion softens, about 3 to 4 minutes.
05 - Stir in marinara sauce, dried Italian herbs, salt, and black pepper. Simmer for 5 minutes then remove from heat.
06 - In a bowl, combine ricotta cheese, Alfredo sauce, sour cream, and egg. Mix until smooth and uniform.
07 - Spread half of the cooked spaghetti evenly in the bottom of the prepared baking dish. Pour half of the Alfredo mixture over the spaghetti and spread evenly. Top with half of the meat sauce, followed by 1 cup mozzarella and 1/2 cup Parmesan cheese.
08 - Repeat layers with remaining spaghetti, Alfredo mixture, meat sauce, and finish by sprinkling with remaining mozzarella and Parmesan cheeses.
09 - Cover the baking dish with foil and bake for 30 minutes.
10 - Remove foil and continue baking for an additional 10 minutes until cheese is bubbly and lightly browned. Let rest for 10 minutes before slicing and serving.
