Here's my recipe and it will feed A LOT...
-1 lb. elbows
-1 can evaporated milk (not sweetened condensed milk)
-4 cups milk total including the can of evaporated milk. I use 1/2 & 1/2 or whole milk.
-1 1/2 lbs. shredded extra sharp cheddar cheese.
-4 eggs
-1 stick on unsalted butter
In a large bow, mix the milk and eggs together. Cook the elbows and drain. Melt the butter in an aluminum. I use the small pan because I like thick macaroni and cheese. If you like it thin, use the large pan. Put the hot noodles in the pan with the melted butter and stir in the cheese. Here's where you can adjust the flavor by adding any cheese you like such as Asiago, Parmesan, Gouda, Swiss, etc. We like cheese with a bite so I'll add in 8 ozs. or so of Parmesan. Now pour in the milk/egg combination and stir well to combine. Bake at 350℉ for about an hour or until it's bubbly and the cheese starts to brown. Top with more shredded cheese and cook until golden brown.
I often make this up and just let it sit on the counter until I'm ready to cook it. The noodles may absorb most of the milk and it may look dry, but it is fine. I try to time it to be ready with whatever else I'm smoking or grilling.
