Extra creamy and comforting Slow Cooker Potatoes au Gratin. Quick, easy, a smooth cheese sauce and delicious flavor. A versatile side dish!

There’s one side dish the whole family goes crazy for: cheesy potatoes. It doesn’t matter what kind of cheese or what kind of potato or how they are cooked. If potatoes are covered with a cheese sauce, then the family is in!

Some potatoes au gratin use fancy cheeses and are cooked in the oven, but we made our recipe a little extra comforting by adding Velveeta (which yes, does melt super creamy…there’s nothing like it!) and cream cheese. This recipe? Easy and delicious!

What is the difference between au gratin and scalloped potatoes?

The main difference between au gratin potatoes and scalloped potatoes are the addition of cheese. Scalloped potatoes are generally just cooked in a white sauce, while potatoes au gratin have cheese.

You can also make “au gratin” recipes with vegetables other than potatoes. Think broccoli au gratin, carrots au gratin….you get it. Just add cheese!

How to Make Slow Cooker Potatoes au Gratin

  • Heat the milk in a small saucepan over medium low heat until bubbles start to form around the outside at the top of the milk and it starts to steam. Remove from the heat.
  • Add the cream cheese, Velveeta, garlic, nutmeg, paprika and black pepper and stir until smooth. The milk should be hot enough to melt the cheese.
  • Spray a slow cooker with cooking spray. Layer ¼ of the potatoes on the bottom of the slow cooker. Add ¼ of the sliced onions, then ¼ of the cheese mixture.
  • Repeat until all ingredients are used.
  • Cover and cook on low for 6-7 hours until most of the liquid has been absorbed. Do not leave cooking longer as this recipe will burn.
  • Serve immediately. Add more milk to refresh leftovers if needed.

Frequently Asked Questions

Can you put raw potatoes in a slow cooker?

Yes! Potatoes cook best with liquid in a slow cooker, so it’s important to add the sauce to cover the potatoes.

Do you have to peel potatoes for au gratin?

Nope! I like to leave the skin on, but you can peel them if you’d like.

Can I cook this on high?

Because milk can curdle, it’s best not to cook these potatoes on high.

Can you make potatoes au gratin in advance?

For the best texture, these potatoes should be served the same day you make it. nce completely cooled store in the refrigerator, covered, for up to 4 days.  When reheating add a splash of milk to freshen up.
