Slow Cooker Potato Soup

Soup doesn’t get much easier than making it in the slow cooker, does it? And here we have one of the ultimate comfort food soups made in the slow cooker. I’ve already posted four slow cooker soup recipes this season and they’re quickly becoming my favorite way to make soup so I figured I may as well post another.

Potato soup is definitely one of my favorite soups. I make it probably two or three times a month, especially during the winter.

Tips for This Recipe

  • Don’t skip the bacon or cheese. They add lots of flavor.
  • Try it with some ranch dressing in place of sour cream.
  • Check the soup at the earlier time noted, several reviews have commented that they’re soup is coming out more like a puree so some slow cookers cook hot and I’ve adjusted those times.

    Have this in the slow cooker now, hoping it is cooked through by dinner time since I got a late start on it. I added garlic just because I love garlic. Do you serve this as a main dish and if so, what sides do you serve with it?

      I love it with fresh bread but for a healthier option you could serve it with some kind of salad.

    I made this today and for some reason after 5 hours on high my potatoes were still nearly raw. I think it is my crockpot, it’s pretty old so maybe the high setting does not get hot enough for potatoes. I ended up transfering the mixture to a large pot and cooking it on the stove until the potatoes were done. I put it back in the crockpot and finished as the recipe called. Even though it didn’t work out as planned the soup turned out great! My family loved it!

  • melissa

    Maybe I missed something, but what is the sour cream fo Garnish is what I am assuming since there is i cant find any mention of where it goes.

    Any suggestions how I could make this soup safe for for someone allergic to gluten??

      I know there are a few thickeners out there that can be used in place of flour but I think the most common is probably cornstarch. I would just omit the flour and replace it with 2 1/2 Tbsp cornstarch mixed with 2 1/2 Tbsp water (and don’t cook it with the butter. Rather just add the butter to soup in slow cooker and stir in cornstarch mixture, then let it heat a bit longer, stirring occasionally, until thickened). Hope that helps!

    Great recipe!. The last one we made was like thick mashed potatoes. This recipe turned out soup. We tend to eat vegetarian so we used vegetable broth instead of chicken and it worked perfectly. Also mashed about half of the potatoes and kept half as full chunks. Everyone loved it. Thanks!
