Step-by-Step Instructions
1. Cook the Spaghetti
Bring a large pot of salted water to a boil. Cook spaghetti according to package instructions until al dente.
Drain and set aside.
2. Prepare the Meat Sauce
Heat olive oil in a skillet over medium heat. Add chopped onion and cook until softened, about 3 minutes.
Add garlic and cook for 1 minute.
Add ground beef and cook until browned, breaking it up as it cooks. Drain excess fat if needed.
Stir in marinara sauce, Italian seasoning, salt, and pepper. Simmer for 5–10 minutes to develop flavor.
3. Make the Creamy Layer
In a bowl, mix ricotta cheese, sour cream, and Parmesan cheese until smooth and well combined.
4. Assemble the Casserole
Preheat oven to 180°C (350°F).
- Spread a thin layer of meat sauce on the bottom of the baking dish.
- Add half of the cooked spaghetti.
- Spread the creamy mixture evenly over the pasta.
- Add the remaining spaghetti on top.
- Pour the remaining meat sauce over everything.
- Sprinkle mozzarella and extra Parmesan cheese evenly on top.
5. Bake
Bake uncovered for 25–30 minutes, or until the cheese is melted, bubbly, and slightly golden.
6. Rest and Serve
Let the casserole rest for 5–10 minutes before serving. This helps it set and makes slicing easier.
Garnish with fresh parsley or basil and serve warm.
