This is a result of experimentation from trying to find a macaroni and cheese recipe that appeals to kids but also has enough flavor and difference to be appetizing to adult tastes. This one has it in my book. I hope that all of you enjoy it if you like macaroni and cheese.
1Preheat your oven to 350 degrees (325 if using a glass baking dish) lightly butter a casserole and set aside. Saute the onion in the margarine until the aroma is clear and the onion is slightly "tanned".
2Stir in the flour and cook whisking all the time for 2 minutes or until a smooth paste is formed.
3Slowly add the milk stirring all the time and allow to thicken.
4Add the cheeses and continue stirring and add the salt, pepper and dry mustard. Continue on medium heat and stirring constantly until the cheese is melted.
5Stir in the precooked macaroni and stir to combine and pour into the prepared casserole.
6Crush the Cheetos corn puffs into coarse pieces and sprinkle atop the casserole and put in oven to bake until bubbly and heated all through.
