Macaroni and Cheese

5 cups uncooked pasta shells
1/4 cup plus 2 tbsp butter
1/2 cup flour
4 cups whole milk
4 cups shredded cheddar cheese
1/2 tsp dry mustard
1/4 tsp pepper
1/8 tsp sea salt
1 cup bread crumbs
1/4 cup parmesan cheese
1 tsp paprika

Cook the macaroni according to package directions.  Drain and set aside.

In a large saucepan, melt the butter and reserve 2 tbsp for the topping. Stir in the flour slowly. Keep stirring and brown slightly. Slowly add the milk, stirring continuously and cook until the mixture thickens to a sauce. Add the dry mustard, pepper and salt. Add the cheese, stirring, until melted. Pour the sauce over the macaroni and stir gently.

Pour the macaroni and cheese into a prepared 9x14 inch casserole dish. Rub the remaining 2 tbsp of butter into the bread crumbs and spread evenly over the casserole. Combine the parmesan cheese and the paprika and sprinkle over the bread crumbs. Bake for 30 minutes or until browned and bubbling.
