Cheesy Slow Cooker Scalloped Potatoes

These slow cooker scalloped potatoes are simply amazing just by themselves but work even better as a side dish.

Slow Cooker Scalloped Potatoes

As I just mentioned, you can eat this dish on its own or as a side to another recipe. It’s entirely up to you but keep in mind the amount of food this will create, perfect if you need to feed a crowd. If you do end up with any leftovers, make sure you keep them as they will last a few days in the fridge. You may find the cream will split if you reheat it in the microwave.

Using a mandoline slicer is a great way to speed up the slicing of the potatoes while also getting more consistent slices. The only downside is that they can be very dangerous so make sure you use the guard that comes with it. I just sliced the potatoes by hand when I cooked and filmed this delicious recipe.

Keep in mind, like almost every slow cooker recipe that is an adaptation of an oven recipe there is likely to be some differences between the two. The oven cooks with dry heat so that moisture will evaporate, a slow cooker, however,  retains moisture, so there is likely to be more fluid.

Scalloped Potatoes

There are many different types of potatoes around the world. If possible, I recommend using a potato such as russet, Desiree or one similar to those two.

Recipe Tips

  • If you’re running low on time or can’t be bothered, then you can skip the layering of the ingredients. Just simply mix all the ingredients in the slow cooker and cook for the same amount of time. It’s important to note that it might not come out to be as nice than if you were to layer it.
  • You can cook on low for 8 hours, but you might find the texture of the potatoes might not be as nice. They will be mushier and less crisp around the edges but should still certainly be a great dish.
  • Removing the lid for 15-30 minutes towards the end will allow the sauce to thicken.
  • The video in the middle of this page is a fantastic way to see how to layer this dish correctly.

There are so many potato dishes that you’re able to do in the slow cooker. For example, something like the cheesy hash brown casserole is a perfect alternative to this dish, but it’s a bit unhealthy.

    can you double the recipe in the crockpot?

    1. Gus on

      I can’t see why not, it should work just fine.

  3. Carrie L Burgett on

    Can i use half and half?

    1. Gus on

      It should work fine, but I can’t guarantee it as I haven’t tested using half and half.

    I made this yesterday and they are delicious my only concern was the sauce did not thicken and was very watery what did I do wrong?

    1. Gus on

      There are many reasons why it may not have thickened. I will list a few suggestions for next time.

      You could try leaving the lid slightly ajar for the last hour of cooking. This method will allow the liquid to evaporate.

      You could try mixing in some cornstarch or something similar at the start of cooking. Simply mix in with the cream, this mixture should help thicken the cream.

      Lastly, you can try reducing the cream by half. This will ensure there isn’t as much liquid at the end.

    It flopped. Rather I flopped it, but it came together anyway. I was making a big Sunday meal. Turns out I should’ve started the prep sooner.

    Fearing it wouldn’t be ready on time, I decided to par boil the potatoes briefly. Overdid it. Tried to layer them in crockpot but decided they didn’t need slow cooking at that point So moved it all to 13×9 pan, followed the layering. Cooked it 45 minutes.

    Turned out great, because potatoes and cheese are infallible in my family.

    I gave this recipe 5 / 5
