Tips for Crockpot Au Gratin Potatoes:

  • Slicing Potatoes – We recommend slicing potatoes about the same size. This allows the potatoes to cook evenly.
  • Cheese – When preparing this dish, we recommend shredding cheese from hunk cheese. Pre shredded cheeses have added ingredients that are not necessary. Freshly shredded cheese melts and taste better in this recipe.
  • Paper Towel – We like to add a paper towel to the top of the slow cooker before adding the lid. This allows for the paper towel soak up the moisture and gives the top a crispy texture.
  • Prepare Crock Pot – Make sure to spray the slow cooker with cooking spray before layering the ingredients. This helps for easy clean up and to easily serve this dish.
  • Thicken the Sauce – Allow the milk mixture to thicken before layering in the slow cooker.
  • Cooking Au Gratin Potatoes – This side dish works best when cooking on high.
  • Rest before Serving – We recommend allowing this side dish to rest for about 20 minutes with the lid off to thicken the sauce.

Substitutions and Additions:

  • Change the Potatoes – We used Russet Potatoes in this recipe but you can also use Yukon gold potatoes or red potatoes.
  • Potatoes – We prepared the potatoes by peeling them, but you can easily leave the peel on. It is your preference on how they are prepared.
  • Change the Cheese – Sharp Cheddar Cheese adds delicious flavor, but you can easily use other types of cheese. Mix in pepper jack cheese or Colby Monterey Jack Cheese is a great options.
  • Seasoning – Feel free to change the seasoning. Italian seasoning is great variation or for extra spice by adding in red pepper flakes.
  • Milk – For a creamier texture, feel free to substitute the milk for heavy cream.

We always have so much leftovers after our Christmas dinner. The good thing is the cheesy potatoes reheat well. Store the leftovers in an air tight container in the fridge. They will last about 3 to 4 days.

Reheat in the leftovers in the microwave or you can reheat in the oven. Place in a baking dish and cover with foil to reheat. Place in a preheated over at 350 degrees. Heat until potatoes are warm.
