Bacon mac and cheese

Mac and cheese is that kind of dish that everybody just love. This dish is one of children favorites and there are lots of variants you can cook them.
What I love most about the mac and cheese is its amazing taste and simplicity. Every time I eat mac and cheese I instantly think of my childhood, maybe this is one of the reason I love them so much.
As you, I have tried lots of mac and cheese recipe but this one is so far my favorite one: the subtle taste of rosemary is just wonderful.
