1️⃣ Preheat Oven:

• Preheat your oven to 350°F (175°C).
• Lightly grease a 9×13-inch baking dish and set it aside.

2️⃣ Cook the Spaghetti:

• In a large pot of salted boiling water, cook the spaghetti according to package instructions until al dente.
• Drain the pasta and set aside.

3️⃣ Cook the Meat:

• In a large skillet, heat the olive oil over medium heat. Add the diced onion and sauté for 3-4 minutes until softened.
• Add the ground beef (or turkey) and cook until browned and fully cooked, breaking it up as it cooks.
• Drain any excess fat, then stir in the marinara sauce, garlic powder, onion powder, salt, and pepper. Let it simmer for 5-7 minutes, then remove from heat.

4️⃣ Prepare the Creamy Layer:

• In a mixing bowl, combine the softened cream cheese, sour cream, cottage cheese (or ricotta), and half of the shredded mozzarella cheese. Mix until smooth and creamy.

5️⃣ Assemble the Casserole:

• Spread the cooked spaghetti evenly in the prepared baking dish.
• Layer the creamy cheese mixture over the spaghetti, spreading it out to cover evenly.
• Pour the marinara and meat sauce over the creamy layer, spreading it evenly across the top.
• Sprinkle the remaining mozzarella and grated Parmesan cheese on top.

6️⃣ Bake the Casserole:

• Cover the baking dish with foil and bake for 25 minutes.
• Remove the foil and bake for an additional 10-15 minutes, or until the cheese on top is melted and bubbly.

7️⃣ Garnish and Serve:

• Remove from the oven and let it rest for about 5 minutes.
• Garnish with fresh parsley, if desired, and serve hot.
