How many of you like potato au gratin but hate how it takes so long to make in your oven?? It’s taking up precious space that needs to be used for other dishes (like the main dish)!
That’s where this Crock Pot Potato Au Gratin helps free up that space. While it does need time to cook as any crock pot dish does but at least your oven is free. It’s still delicious, cheesy au gratin potatoes but way easier!
Ingredients needed for this Crock Pot Au Gratin Potatoes:
- Potatoes
- Monterey Jack cheese
- Sharp Cheddar cheese
- Butter
- All purpose flour
- Onion
- Garlic powder
- Milk
- Salt and pepper
A few other great potato side dish recipes are: Slow Cooker Baked Potatoes, Loaded Hasselback Potatoes, Old Fashioned Potato Salad, Cheesy Hashbrown Casserole and Roasted Sweet Potatoes with Cinnamon Glaze. Those slow cooker baked potatoes are life changing, just saying!!
I grew up eating potato au gratin and scalloped potatoes often. Most of the time it was served on a Sunday along with ham, roast, or chicken. Or if we had a little bit of leftover ham my mom would make one of my favorites. Ham and potato au gratin. There is something magical about cheesy potatoes and ham, am I right?!
About this Crock Pot Au Gratin Potatoes:
- You can use Russet or Yukon Gold potatoes for this recipe. You can also peel them or leave the peel on.
- Cut them 1/8″ thick. You can try for 1/4″ but every time I did I had to cook them a lot longer. But every brand of crock pot cooks differently.
- I like to use a combination of cheese. Monterey Jack to make it creamy and smooth and sharp cheddar for the flavor.
- Don’t use pre-shredded cheese for this recipe. They come with powdery additives and may not melt well.
- Use a mandoline or food processor to slice the potatoes as it makes the job much easier!
- This dish doesn’t do well on the warm setting.
- Let the potatoes stand for 20 minutes before serving. This will allow for the sauce to thicken a little and it will continue to thicken as it cools.
You want to know something else?? You can make these comforting potatoes in the summer because…..dun dun dunnnn you are using the crock pot! No turning on the oven, no heating up your house, and yet you can still have these tender, cheesy, and creamy potatoes.
Can you tell how much I love these potatoes?? Better yet, can you tell how much I love my crock pot?? I know the Instant Pot is going crazy wild right now and maybe someday I’ll join in on the fun. But for right now I am going to keep loving my slow cooker and using it for ALL THE THINGS!

Roasted Sweet Potatoes with Cinnamon Glaze
Hi Julie
I am new to your recipes but I was looking for crock pot AuGratins and walla
I want to try them next Easter to make things simpler
Do you see any problems with mixing all together in a bowl and then placing in 9×13 crock pot
Thank you and will be looking for more of your recipes
Hi Linda! I’m glad to hear that you’re trying the recipe. I do not see any problems mixing it all together in a bowl and then placing it in your crock pot! I hope you LOVE this recipe and many others too!
Can this be made with half and half instead of whole milk?
Hi Mary. I haven’t tired making it with half and half but you could try it! It may change the consistency a little bit but probably would be delicious! Hope you enjoy it!
It was amazing and delicious! I recommend stirring during cooking so doesn’t overcook on bottom layer. I’ll definitely make again
Wonderful! I’m so glad you enjoyed them!
Been 4 hours still not cooked did exactly what was stated. Unfortunately I think its the crock pot, maybe I should of pre boiled them for a quicker cooking time. I cut them fairly thin too, they taste great. Just not having good luck with Christmas dinner. Thank you for the recipe though!
Oh bummer! I’m glad you still enjoyed them!
This is so easy and fabulous! I love creamy au gratin potatoes and I know they are a side dish but I could eat these as a main dish! YUM!
Same here, so good! Glad you loved them!
These look so bright and sunny! The only times I’ve tried to make scalloped potatoes, they come out undercooked and gray! But your crock-pot version looks perfect! I’ll have to give them a try!
You’ll love them!
Can’t go wrong with crockpot versions of the classics!
