Bring a pot of water to a boil and add the pasta. To keep it from sticking together, you can add 1 teaspoon of oil into the boiling water. After cooking for the time indicated on the package, rinse with cool water and set aside.
In a saucepan over low-medium heat, melt the butter until just dissolved. Then stir in the flour, white pepper, garlic powder, salt, and onion powder until a smooth paste forms.
To this mixture, pour in the heavy cream slowly while stirring continuously to make sure everything is light and creamy.
Add the grated white cheddar cheese, cream cheese, and Romano cheese and stir until fully melted into the sauce. Remove from heat.
Pour the cheesy sauce over your cooked macaroni and mix until evenly coated.
For a tasty topping, sprinkle extra cheese on top before serving.
Enjoy a hot, delectable White Mac And Cheese just like that served in Arby’s Restaurant!
