Cheesy crock pot au gratin potatoes are the best side dish for any meal. They are creamy and topped off with cheese. Mmmm, so delicious. They make a great contribution to any dinner, or if you want you could even just eat them with a vegetable.

For about the last 15 years, we have done a fundraiser to help pay for our kids scout camp. We would hook up the trailer and head to Idaho. Then we would buy 200, 50# bags of potatoes. Then we brought them back home and deliver them around the neighborhood. Those who had ordered them, would get first dibs and then if there was extra, we would sell the rest of the potatoes. We usually kept 3 bags for ourselves. Like a lot of the families in the neighborhood, we don’t need that many potatoes this year, since we don’t have as many children at home anymore. But I tell my husband, that I need potatoes from Idaho. We both grew up in Idaho and we really miss those famous Idaho potatoes.

So when I got my 50# pound bag of Russet potatoes, I knew that I just had to make some potatoes in the crock pot. I like that you can put them in and leave them. When they are done, they come out perfect and delicious. However, I did have to laugh because when my son came home from work, he told me that the house stunk (garlic) and that we needed to get something that made our house smell like pumpkin!!! I guess I will have to find a candle because if I make pumpkin treats all the time I will be in trouble. They are some of my favorites!

Like I said, I did use Russet potatoes, but you can use Reds or even Yukon golds. I guess that we are use to the Russet potatoes, because that is what we grew up with. Even my husband grew up with Russets, and he raised potatoes in his younger years. However, I do love the reds with a little bit of skin left on them and country gravy on top! I invite you to try this cheesy crock pot au gratin potatoes recipe and I hope that you will enjoy it as much as we did!
