Sometimes you just need something super decadent =) Yummm!

Blue Ribbon Recipe

This is not the mac and cheese you grew up eating... it's super rich and decadent. The creamy cheese sauce is a nice mixture of the mild Fontina with the zesty Asiago. Caramelized onions add a wonderful flavor and texture. Topping this, though, with croutons and Gruyere brings this mac and cheese to a whole new level. This is not a recipe you'd make every day, but great for special occasions.
