In a saucepan, melt butter. Stir in flour and milk and cook on medium heat until thick. Add salt and pepper. Stir constantly. Add shredded cheese and stir until all cheese is melted into the sauce. Spoon the cheese sauce onto cooked macaroni in a greased baking dish. Top with breadcrumbs and paprika. Bake 30 min at 350 degrees.
Add in ideas: Chopped and cooked leaks or onions (cook in the butter at the beginning) and/or cooked bits of bacon.
