Instructions
- Preheat oven to 350°F (175°C) and lightly grease a 9×13 inch casserole dish.
- Bring a large pot of salted water to a boil, cook 16 ounces of spaghetti until just shy of al dente, drain and set aside.
- In a large skillet over medium-high heat, brown 1 pound ground beef, breaking it up as it cooks. Season with 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon Italian seasoning, salt, and black pepper. Drain any excess fat.
- Stir 24 ounces marinara sauce into the browned beef and simmer for about 5 minutes to meld flavors, then remove from heat.
- In a mixing bowl, beat together 8 ounces softened cream cheese and 1 cup sour cream until smooth, fold in 1 cup cottage cheese to create the creamy layer.
- Place half of the butter pats on the bottom of the prepared casserole dish, spread half of the cooked spaghetti over the butter in an even layer.
- Spread the cream cheese, sour cream, and cottage cheese mixture evenly over the first spaghetti layer.
- Spoon half of the meat and marinara mixture over the creamy layer, spreading to cover.
- Add the remaining spaghetti as the next layer, place the remaining butter pats on top of the pasta, then spread the remaining meat sauce evenly over it.
- Top the assembled casserole with 2 cups shredded mozzarella and 1/2 cup grated Parmesan, spreading the cheese into an even layer.
- Cover the casserole dish with foil and bake in the preheated oven for 30 minutes.
- Remove the foil and continue baking for an additional 15 minutes, or until the top is bubbly and golden.
