Easy Slow Cooker Cheesy Scalloped Potatoes

Slow Cooker Scalloped Potatoes is an easy casserole dish that is flavorful, creamy, and cheesy. It is one of the best comfort food to serve during the holiday season such as Thanksgiving or Christmas. You can serve it as a main dish or side dish. No matter how you serve it, we guaranteed that you will love every single bite of it!

To make it, all you have to do is layer your potatoes between the homemade cream sauce and cheese. Then, let the crockpot do its magic. I also love the oven version, but the slow cooker version is richer, creamier, and cheesier. Because the slow cooker maintains the moisture and heat, the sprouts end up super tender, creamy, and very flavorful.

Also, I like to serve them crispy on top. Once they are done cooking, I quickly pop the casserole into the oven for a few minutes and broil it. As a result, the dish is tender and creamy inside, and crispy on the outside, with a golden brown color. This extra step just makes this dish so much better!
