CrockPot Au Gratin Potatoes

Side dishes are the under-appreciated course of a meal. I think we take them for granted, and push them to the side of our main course.Well tonight the star of the show, and the crockpot, was these Au Gratin Potatoes. Sure I could have opened a box of Au Gratin Potato Mix, but it would not have tasted nearly this good, or made my house smell near as savory! Plus, if you are in a hurry or don’t want to heat the house up, these bad boys can cook in the crockpot instead of the oven! How cool is that!?

Recipe tips!

Use your food processor to slice the potatoes. This make this super easy and much faster! Seriously less than 30 seconds and the potatoes were perfectly sliced.

You can place a smaller casserole dish inside of your crockpot. If you are making a smaller dish your item will cook faster and more evenly in a casserole to fit the recipe.
