SLOW COOKER au Gratin Potatoes - not only is this recipe ideal for any day of the week, along side chicken, pork or beef BUT it's going to be a GAME CHANGER for the holidays. No more potato dish taking up that valuable oven space! Now you've got room and time! I will admit, I wasn't sure this recipe was going to work. I don't like potatoes that have weird consistency but these had the perfect consistency to them. I'm so glad I tried this!
