I layer in a casserole, noodles, salt, pepper, butter chunks, a little flour sprinkled on and sharp cheese. Finishing with cheese on top. Mix 1 can milk with 2 tbsp of flour and pour over the top, enough to come up maybe an inch from the top (may need more) . Bake for about 30 minutes at 350 covered then uncover and back about 10 mins till golden and bubbly. You could use any kind of cheese but we like the extra sharp. My friend makes a similar recipe but she shortens the time by making a roux with the butter and flour, mixing in the milk and cheese, salt and pepper then pouring over the top of the pasta and baking 15 mins till bubble, if you want it golden on top save a little cheese to add to the top.
