Combine buffalo sauce and chicken add more or less to taste. Set aside.
Make cheese sauce by melting butter and stirring in flour cook over medium heat a few minutes. Slowly whisk in milk to make a cream sauce. Add cheese and seasoning.
Stir seasoned chicken into cheese sauce.
Stir in cooked macaroni. Add some of the pasta water if you want a thinner consistency. You can serve it now topped with blue cheese but I like to bake it for extra yumminess.
Pour into a glass casserole dish and top with blue cheese crumbles.
Sprinkle with panko bread crumbs on top and spray with oil.
Broil until topping is crisp. Do not leave unattended the breadcrumbs can burn quickly.
Serve and enjoy!
