Copycat Costco Mac And Cheese
  1. Cook the Pasta: Bring a large pot of salted water to a boil. Cook the cavatappi pasta according to the package instructions until al dente. Drain and set aside.

  2. Make the Roux: In a large saucepan over medium heat, melt the butter. Once fully melted, whisk in the flour. Stir continuously for about 1 minute until the mixture is smooth and bubbly.

  3. Create the Cheese Sauce Base: Gradually add the heavy cream and whole milk to the roux, whisking continuously to maintain a smooth consistency. Continue cooking, stirring frequently, until the mixture thickens and begins to simmer.

  4. Melt the Cheese: Reduce the heat to low and stir in the Romano and Parmesan cheeses. Mix until the cheeses are fully melted and the sauce is creamy and smooth.

  5. Season the Sauce: Add the salt, white pepper, paprika, and garlic powder. Stir well, then taste and adjust the seasonings if needed.

  6. Combine with Pasta: Stir the cooked cavatappi into the cheese sauce, ensuring the pasta is fully coated.

  7. Bake: Preheat the oven to 400°F. Transfer the mac and cheese into a greased baking dish, spreading it evenly. Sprinkle the shredded cheddar cheese over the top. Cover the dish tightly with foil and bake for 20–25 minutes, until the cheese is fully melted and gooey.

  8. Serve: Let the mac and cheese cool slightly before serving. Enjoy!
