Step 4: Preparing the Creamy Topping
In a separate bowl, combine:
1 cup sour cream
1 cup ricotta cheese
This is the secret to this casserole’s signature creamy flavor. If you’re unsure about the ricotta, don’t worry! Once baked, it melts into the dish, adding rich flavor without making it heavy.
Step 5: Assembling the Casserole
Preheat the oven to 175°C (350°F).
In a greased 23 x 33 cm (9 x 13 inch) baking dish, arrange the ingredients in the following order:
Half of the cooked pasta
All of the creamy ricotta and sour cream mixture
Half of the meat sauce
The remaining pasta
The remaining meat sauce
Sprinkle the top evenly with cheddar and mozzarella cheese.
Optional: Garnish with fresh parsley for a touch of color.
Step 6: Baking
Cover the dish with aluminum foil and bake in a preheated oven for 25 minutes.
