Here is the recipe (with the modifications i have made.
8 ounces of macaroni (i don't use the elbow shaped, i typically use the spirals or coil shaped noodles)
1 cup whole milk
3/4 cup heavy cream
1/4 teaspoon sugar
large pinch of cayenne pepper
3/4 teaspoon sea salt
1/2 tablespoon (heaping) ranch seasoning
10 ounces of sharp cheddar cheese grated
5 ounces of monterey jack cheese grated
6 ounces of parmesan cheese grated
I typically use the lazy(pre-shredded) cheese
pre-heat oven to 350 degrees, cook macaroni according to package, drain and set aside. In a large mixing bowl, beat the eggs. Add the milk, heavy cream, sugar, cayenne pepper, salt, ranch seasoning. mix well. mix in the noodles and stir till they are coated. Add in the cheese and mix until fully incorporated. Pour into large baking dish, cover with foil and bake for 30 to 35 minutes. Remove foil for last 5 minutes.
There ya have it. And yes, it is as healthy as it sounds.
