Directions
1. Preheat the Oven:
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish lightly with butter or nonstick spray to prevent sticking. This step ensures the casserole slides out easily and develops a perfectly browned, cheesy crust.
2. Make the Creamy Sauce:
In a large mixing bowl, combine the softened cream cheese, milk, garlic powder, salt, and black pepper. Stir or whisk until smooth and creamy. The milk helps thin the cream cheese into a silky sauce that coats the pasta evenly.
3. Combine with Pasta:
Add the cooked and drained spaghetti to the bowl, tossing gently to coat every strand in the cream cheese mixture. Stir in half of the shredded mozzarella cheese — this adds stretchiness and creamy texture throughout the dish.
4. Assemble the Casserole:
Pour the spaghetti mixture into the prepared baking dish, spreading it out evenly. Sprinkle the remaining mozzarella cheese and the grated Parmesan evenly over the top. The mozzarella melts into a gooey topping, while the Parmesan adds a savory, golden crust as it bakes.
