Slow Cooker Au Gratin Potatoes and Ham is comfort food at its best! It is also a great recipe to use up leftover ham after a holiday dinner. You can use any kind of baked ham or spiral ham and it will taste great.
This is a no-fuss slow cooker recipe. All of the ingredients can be prepared quickly and easily. I especially like the use of thyme leaves in this Au Gratin dish. Thyme has a light mint and lemon scent and taste. Just a little bit of thyme goes a long way and really adds a delicious flavor to this dish.
The term “Au Gratin” is French and refers to a dish topped with grated cheese and/or browned bread crumbs. It is difficult to achieve the browned look of au gratin when cooking in a slow cooker, but the taste of the dish is pretty much the same. The potatoes along the sides and bottom of the slow cooker do brown a little as they cook, and gently stirring the potatoes before adding the cheese on top will bring some of the more browned potatoes to the top. Ham freezes very well. I usually freeze leftover ham and save it for recipes like this. The ham can be added frozen to the slow cooker. It will thaw and warm as the potatoes cook.
If you want to make this a vegetarian dish or use it only as a side dish, you can substitute mushrooms, carrots, or extra potatoes for the ham.
