Macaroni and Cheese

My second favorite food (mashed potatoes wins first place)! All day, I have been craving macaroni and cheese. It just doesn't fit in my diet since I am trying to manage my weight. So, I don't buy it or eat it often. But tonight, I will be indulging. I can't wait! Macaroni and Cheese 3/4 c dry breadcrumbs 4 T butter (divided) 8 oz butter 1 T all-purpose flour 1 small onion, minced Salt and pepper to taste 1/4 t dry mustard 1 1/2 c milk 2 c shredded sharp cheddar Preheat oven to 350. Grease a 2 qt casserole dish. Mix bread crumbs and. 2 T melted butter in a small bowl and set aside. Cook macaroni according to directions, drain and put in the casserole dish. While the pasta is cooking, melt 2 T of butter in a saucepan over medium heat. Cook the onion in the butter until translucent (about 5 minutes). Stir in the flour, pepper, salt and dry mustard. Pour in the milk and bring to a simmer. Stir constantly until the sauce has thickened (about 10 minutes). Remove from heat and stir in the cheddar cheese until melted. Pour the sauce over the macaroni. Add the breadcrumb mixture evenly to the top. Bake for 20 minutes or until the top is golden and bubbly.
