1. Cook the Pasta
Boil the spaghetti until just al dente (it will bake more later). Drain and set aside.
2. Make the Meat Sauce
Brown the ground beef (or sausage) in a skillet. Drain excess grease. Stir in the marinara sauce and let simmer for 5 minutes.
3. Prepare the Creamy Cheese Mixture
In a medium bowl, combine cream cheese, sour cream, and cottage cheese until smooth and creamy. This is the magic “million-dollar” layer.
4. Assemble the Layers
- Grease a 9×13-inch baking dish.
- Lay half the butter slices on the bottom.
- Spread half the cooked spaghetti over the butter.
- Spread the entire cheese mixture evenly on top.
- Add the remaining spaghetti over the cheese layer, followed by the rest of the butter slices.
- Pour the meat sauce over everything.
5. Top with Cheese
Sprinkle mozzarella and Parmesan over the casserole until it’s fully covered in cheesy glory.
6. Bake
Bake at 350°F (175°C) for 35–40 minutes, uncovered, until bubbly and golden.
