Scalloped Potatoes in the Oven or Slow Cooker

Sometimes you just need a choice.  I usually do homemade scalloped potatoes in the oven, but this time I needed to make them early in the day.

It was  one of those nights when you rush in the door at dinner time and need it to put itself on the table.

You know the kind.

Slow cooker to the rescue.  Again.

Here’s what you’ll need:

  • About 2 lbs. potatoes, any variety (I used 7-8 good sized red)
  • 2 Tbs. butter
  • 2 Tbs. flour
  • 2 cups hot milk
  • salt and pepper

Scrub the potatoes.  You can peel them or leave the peels on.  Slice thinly.  (I love my Rada Cutlery Cook’s Knife for this job.)

Melt the butter over medium heat in a skillet.  Stir in the flour and cook for a minute or two.  Whisk in the hot milk.  Keep whisking until smooth.  Cook until bubbly and slightly thickened.  Season with salt and pepper.

Butter the crock of a slow cooker or a casserole dish if you’re using the oven.  Put in the potato slices.  Pour sauce over the potatoes.

Cook on low 7-8 hours or high 5-6 hours.  Or bake uncovered at 350 degrees for 1 1/2 hours or until the potatoes are tender when poked with a fork.

Serves 6-8 people.

      Technically it is Scalloped Potatoes if it is without cheese and AuGratin if it has cheese in it. But I have always called my Mother wonderful cheesy potatoes Scalloped Potatoes anyway.

    What size crockpot did you use? Thanks!

    • My crockpot is 6 quart, but this would fit in a smaller one. It probably would fit in a 4 quart.

      • Thanks! I just ‘assembled’ it. Increased it by 50% – 11 potatoes, 3 c of milk, etc. Seemed right size for my 5 qt slow cooker. My slow cooker doesn’t work well if it isn’t mostly filled. I guessed on the salt – 1/2 tsp. Any idea what you put in? Also, the liquid didn’t cover the potatoes. Does that matter? Thanks for your help! This is a trial run for in-law dinner this weekend :).

  8. hi can I use Half & half for the milk? do I have to heat it? I have a recipe that uses half & half.
    its an oven recipe, scallop potatos, then slices of onion, slices of butter and start the next layer, finish off with half & half and bake in oven. but i want to do it in the crock pot. thanks

    • For this recipes you make a white sauce, which is typically made with milk. I think it would be pretty thick if you use half and half.

  9. Thank you for this wonderful scalloped potato recipe. Frustrates me when people post scalloped potato recipes with cheese in the ingredients. If I wanted cheese in it I would search for au gratin potatoes and not scalloped.
