Cook spaghetti. Bring a large pot of lightly salted water to a boil. Cook the spaghetti in a large pot of lightly salted boiling water until it is cooked through but still firm to the bite, about 8 to 12 minutes. Drain.
Cook the ground beef. While the pasta is cooking, brown the ground beef over medium heat until it is cooked throughout, about 5 to 7 minutes. Drain and discard any grease. Stir in the marinara sauce.
Mix the cheese layer. Stir together the cream cheese, ricotta cheese, sour cream, and Stone House Seasoning in a medium bowl.
Layer the casserole. Add 1/2 of the butter slices to the bottom of the 9x13 baking dish. Top with 1/2 of the cooked noodles, then 1/2 of the cheese layer mixture, then 1/2 of the beef and marinara sauce. Repeat the layers (butter, noodles, cheese mixture, and beef marinara sauce).
Bake. Bake in the preheated oven for 30 minutes. Top with the mozzarella and Parmesan cheeses and bake for an additional 15 minutes until the cheese is melted.
