"I have been making this recipe every Thanksgiving for the family for years now. Now, I would love to share this recipe with Allrecipes as a special treat! This is macaroni that I will always treasure as one of the best recipes I have come across! Kids and Adults love it."
Preheat oven to 350 degrees. Boil the macaroni in a 2 quart saucepan in plenty of water until tender, about 7 minutes. Drain. Add back to the saucepan, mix butter and cheese. Stir until the cheese melts. Add in the eggs, sour cream, soup, salt, milk, mustard and pepper and stir well.
Grease an 11x7 glass baking dish. Add in the macaroni mixture. Bake in the oven uncovered for 40 minutes. Cool for 5 minutes before serving.
