Slow Cooker Cheesy Potatoes Recipe

cheesy potatoes

I am trying to get away from boxed pastas and potatoes. In years past it was so easy to just make boxed scalloped potatoes. Now that I am paying attention to ingredients a bit more, I would rather make homemade items. It’s actually very easy to make cheesy potatoes from scratch- especially if you use a slow cooker!

For this recipe, I use a mandolin to slice the potatoes. A mandolin ensures that the potatoes are sliced a consistent thickness. This ensures even cooking. Be cautious using a mandolin though as it’s easy to cut yourself if you don’t use it correctly!

cheese sauce

Before the ingredients are placed in a slow cooker, a cheese sauce is made. This is done by sauteing the onions in butter until soft. Then add the cream of mushroom soup,water, cheese and seasoning.

Make sure you spray the slow cooker with cooking spray. Layer half of the potatoes on the bottom of the slow cooker pot. Pour half of the cheese sauce over the sliced potatoes.

Then place another layer of potatoes and top with the remaining cheese sauce. The cheese sauce will incorporate with the potatoes as it cooks.

Recipe: Slow Cooker Cheesy Potatoes


  • 4 large potatoes, peeled and thinly sliced
  • 1/2 cup chopped onion
  • 1 tablespoon butter
  • 1 can condensed cream of mushroom soup (10.75 ounce) or homemade cream of mushroom soup
  • 1/2 cup water
  • 1 cup shredded Cheddar cheese
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon black pepper


  1. In a sauce pan melt butter and saute onions until soft.
  2. Add cream of mushroom soup, water, cheese and seasoning. Heat until the cheese melts and it becomes a smooth sauce.
  3. Spray a slow cooker with cooking spray.
  4. Place a layer of potatoes on the bottom of the slow cooker. Pour some sauce over them. Place another layer of potatoes and then the remaining sauce over the top.
  5. Cook on high for 4 hours.


  • Add a cup of cubed ham for a whole meal.
  • Experiment with other cheeses.
  • You can also use cream of chicken soup if you don’t like mushrooms.

    Thank you so much for posting a recipe that just doesn’t come from a box. I am so tired of these ‘easy’ or ‘fast’ recipes that only use foods that are already prepared. We love cooking from scratch in our home, and are always delighted to come across a good recipe like this one. Recipe has been Pinned.

    • Hi Danielle,
      Thanks so much for the pin! I am trying to cook more from scratch and cooking ahead. Look for a recipe coming soon for copycat Parmesan Pasta Roni! I was experimenting this weekend for a make ahead seasoning mix for pasta to make like the boxed stuff. Still fine tuning, but it is super easy to make!

  2. My son will love these. Can you freeze it once the recipe is made?Trying to fill up my freezer with”homemade” pre-made foods!!

    • Hi Cat,
      So sorry for the late reply. I am not sure if you can freeze the potatoes. I have never tried it. You can freeze cooked potatoes though so my best guess is that it will work! Good luck!

  3. I just turned on the crock pot!! I am so excited for these! I am a bit concerned that I don’t have enough sauce to cover the potatoes, they were pretty big! hope they turn out well! :)

  4. I can already tell these are going to be good and they haven’t even finished cooking yet! I’m so excited for dinner tonight, I paired them up with a meatloaf and beans for a yummy homemade meal!
