These Slow Cooker Cheesy Mashed Potatoes are a cheese lover’s dream. Very easy to make in the slow cooker and keep warm for dinner or a potluck.

Hi Slow Cooker Friends! How good do these potatoes look? I knew that this dish would be good, but I had no idea it would be the best potatoes I’ve ever ate! You may wonder why I add the chicken bouillon cubes.

The chicken bouillon adds a hint of flavor, just like it does it in a few of my meatless soups. No chicken flavor I promise. Just perfectly seasoned potatoes.

I made Fried Mashed Potato Patties the next day for breakfast. Have you ever made these? Fried mashed potato patties are leftover mashed potatoes that are lightly battered (this helps keeps them from sticking and falling apart). Then fried in butter. These patties are best served with over easy eggs and toast.

How to make Slow Cooker Cheesy Potatoes:

  • Start by peeling 4 pounds of russet potatoes, cubing them and add them to the slow cooker.
  • Add enough water to cover the potatoes.
  • Add 2 chicken bouillon cubes.

  • Cover and cook on high for 4 hours without opening the lid during the cooking time.
  • When the cooking time is done, drain the water off the potatoes.
  • Add salt, sour cream and 1 cup of shredded cheese.
  • Blend together with a hand-held mixer.
  • Add 2 more cups of shredded cheese to the potatoes and replace lid for 10 minutes or until cheese has melted.

My tips for slow cooker cheesy mashed potatoes:

  • Why dirty a strainer? Wearing oven mitts, hold the slow cooker insert with the lid opened a crack and pour the water down the sink drain.
  • Take care to not over mix the potatoes; they will become gluey in taste and texture.
  • Be careful not to scrape the beaters against the ceramic slow cooker insert as much as possible.

      This did not work for me. Potatoes were not soft enough to mash. Cooked on high in the slow cooker for 4 hrs. Such a disappointment

      Can you substitute butter for the sour cream?

        Yes, personally if I was omitting the sour cream, I would do 1 stick of butter and a splash of milk.

      Easy and cheesy! Just the way it should be. I love the convenience of not using the stove, perfect for when you are making a lot of food!

      I love how easy and cheesy these are! I think I will serve this as a side for Easter dinner, since preparing them in the crock pot will free up my stove top for other things!

      I love cheese and mashed potatoes – this looks like a match made in heaven. I was thinking of adding some cloves of garlic and using chicken broth, what do you think?
