In a saucepan over medium heat, melt butter. Whisk in flour, and then slowly add in the warmed milk, whisking continuously. Cook for 5 minutes, stirring so it doesn't stick, until smooth and thick. It should be able to coat the back of a spoon.
Cook the ziti 2 - 3 minutes less than the package instructions. (To ensure it won't get too soft when the dish is baked). Drain and rinse with cool water.
Preheat oven to 350℉. Spray a deep 9x13 inch dish with nonstick spray.
