06 - Sprinkle 6 tablespoons all-purpose flour into the butter mixture, whisking continuously until a paste forms.
07 - Slowly whisk in 3 cups whole milk in increments of ¼ cup, ensuring a smooth mixture before adding more.
08 - Allow sauce to simmer for 4 minutes while whisking occasionally until thickened.
09 - Evenly pour the prepared sauce over the cheese layer, spreading carefully to reach all corners.
10 - In a small bowl, combine 1 ½ cups Panko breadcrumbs with 4 tablespoons softened butter. Spread mixture evenly on top of the sauce.
11 - Bake uncovered for 30 to 40 minutes, until sauce is bubbling and breadcrumb topping is golden brown.
12 - Remove from oven and let rest for 5 minutes to set the sauce. Garnish with chopped parsley if desired and serve warm.
