Mac N Cheese to feed a crowd

Next week we are hosting "The Great Consular Section Thanksgiving Extravaganza!" Ok, well, it's not actually all that impressive, that's just how I refer to it in my head... Anyway, we are hosting DH's section for a Thanksgiving lunch.  All totaled we are looking at about 20 people to come and eat Turkey.  I went to the fish market this morning and bought two 10lb turkeys to serve.  I took my camera, but was too focused on not slipping on the muck to take any pictures, but I intend to go back so I will be sure to snap some pictures next time.
Anyway, last night I made the Macaroni and Cheese to put in the freezer for the extravaganza and I realized that for this I actually have my own recipe.  It tastes very similar to my Aunt P's recipe which uses cream of mushroom soup and old bay seasoning, but since I have neither cream of mushroom soup nor old bay seasoning I can't make that.
Anyway, I made this recipe, but tripled the recipe.  I took the double portion, without the bread crumbs and put it in the freezer for next Wednesday.  In case your wondering, this is what a double portion of Mac n Cheese looks like.

The third portion I topped with bread crumbs right away and served it for dinner with sweet and sour cabbage and a tomato, cucumber and basil salad.
