"I made this for thanksgiving in one large casserole dish. I substituted a bunch though, a different pasta, and a combo gruyere/cheddar, and I used half and half instead of whole milk. It came out nice, but could have been a bit more creamy with a little bit more flavor. I think next time I will use the brie and maybe buttermilk instead, or half the whole milk and half 1/2 and 1/2. Might add a little more color next time. Loved the butter breadcrumbs :)
