  • Layer the potatoes. Then layer a ⅓ of the sliced potatoes in the bottom of the crock pot.  Pour approximately ⅓ of the sauce on top of the potatoes.  Continue with these layers 2 more times. 
  • Add paper towels on top. Place a few paper towels on top of the crock pot and then add the lid (this will soak up the extra moisture and make the top of the potatoes crispier). 
  • Cover and cook. Then cook on high for 3-5 hours until the potatoes are tender and cooked through.  Remove the lid for the last 30 minutes of the cook time to allow the sauce to thicken.

Crock pot au gratin potatoes tips:

  • Use freshly shredded cheddar cheese so that it melts smoothly and evenly in this recipe. The texture will be so much smoother and creamier. Pre-shredded bags of cheese have additives that do not melt well.
  • Slice the potatoes thinly and evenly. This will ensure they cook at the same speed.
  • Placing a layer of paper towels under the crock pot lid helps to make the top crispy like oven baked au gratin potatoes. This trick is super handy.
  • Generously spray the slow cooker with cooking spray. You can also use crock pot liners. Either option will greatly help with clean up.
  • Allow the potatoes to sit before serving. This will give the potatoes time to thicken.
  • Use real butter in this recipe Margarine contains oil and can make the dish greasy.
  • If you have a mandoline tool, this is the easiest way to slice the potatoes and ensure they are even. Each slice will be the exact same thickness.
  • Cook the flour with the butter for the required 2 to 3 minutes. This will help to remove the flour taste from the mixture. It also helps the flour to act as a thickening agent which results in a thick and creamy sauce.
  • Prevent the sauce from curdling by using medium high heat on the stove top.

Variations

  • Yukon Gold or Russet Potatoes make great options for this recipe.
  • You can peel the potatoes or leave the peeling on.
  • Sharp cheddar gives this amazing flavor but you can also combine various types. Monterrey Jack and Sharp Cheddar combine perfectly.
  • Try adding other seasonings such as paprika to the potatoes.
  • Heavy cream can be substituted for the milk in this recipe.

How to store:

Place the potatoes inside an airtight container. Refrigerate up to 4 to 5 days.

They are best served warm but can still be reheated. You can use the microwave until heated through.

If using the oven, cover the potatoes in foil. This will help to prevent them from drying out and getting too brown.
