How to Make Million Dollar Spaghetti

1. Cook the Pasta

Cook the spaghetti in salted water until al dente. Drain and lightly toss with a little butter if desired.

3. Make the Cheese Filling

Mix together the softened cream cheese, ricotta cheese, and sour cream until smooth.

4. Assemble the Casserole

Layer half of the cooked spaghetti in a greased 9×13-inch baking dish. Spread the creamy cheese mixture over the pasta, then top with the remaining spaghetti. Spoon the meat sauce over the top and finish with mozzarella and Parmesan cheese.

Bake at 350°F for 30–35 minutes until the cheese is melted and bubbly. Let rest for about 10 minutes before serving.
