I about died when I saw a version of this recipe on Martha Stewart's website. I am a huge potato fanatic and these just looked stunning! I altered a couple of things in her recipe, but followed her technique and concept.
I used some pancetta in my version. Bacon may work fine, too.
They key to this recipe is getting the potato slices as thin as you can, so prepping the potatoes takes a little time. Also, patience is a must as this dish bakes for about two hours total. (It's totally worth it - trust me!)
This is a dish that is super impressive-looking and would really wow at a dinner party!
