Preheat your oven to 350°F (175°C). In a large pot, boil salted water and cook the cavatappi pasta according to package instructions until al dente. Drain and set aside.

Make the Cheese Sauce

In a large saucepan over medium heat, melt the butter. Stir in the flour and cook for about 1-2 minutes, stirring constantly. Gradually whisk in the milk until smooth. Continue to cook, stirring frequently, until the sauce thickens.

Add Cheeses

Once the sauce has thickened, reduce the heat to low and add the cream cheese, cheddar cheese, mozzarella cheese, and parmesan cheese. Stir until all the cheese has melted and the sauce is creamy. Season with salt, black pepper, garlic powder, and paprika.

Combine Pasta and Sauce

Add the cooked cavatappi to the cheese sauce, stirring well to combine. Pour the mixture into a greased 9x13 inch baking dish.

Prepare the Topping

In a small bowl, mix the breadcrumbs with olive oil until evenly coated. Sprinkle the breadcrumb mixture over the mac and cheese.

Bake

Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and crispy.

Serve

Remove from the oven and let sit for a few minutes before serving hot.
