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.

    Do you add the ingredients you cook on the stove to the slow cooker before or after you start cooking everything in the slow cooker? A little confused…

      After, it helps thicken up the soup but if it cooked with it the whole time it would separate.

  • Brittany

    I would definitely add the evaporated milk last. I didn’t and the milk separated and curdled. The house smells amazing though.

  • Kara

    I made this soup today and it was delicious! Best potato soup I’ve ever had! I did make two alterations though. The first one was I used half & half, as this was all I had. The second was I omitted the flour all together due to gluten allergies. I considered using rice flour or potato starch but decided if it was too thin I’d mash some of the potatoes. I added the butter directly to the soup. Once it was cooked, I stirred it a bit and that thicken things up perfectly. Like I said, it was so delicious! So much so, that there was none left!!! Thank you!

  • Victoria

    This was amazing!!! Will definitely be adding this recipe to my book for dinners! Thanks for sharing!

    I made this today and for some reason it seems to have a strong flour after taste. I prepared it the way the instructions said. My husband and I added more broth and added all of the topping into the soup. I doubled the sour cream and added an additional 1/2 c of evaporated milk. It tastes better, but I can still taste it. I’m disappointed

      I might recommend cooking the butter/flour mixture longer as that helps rid the flouriness you might be tasting, it should become lightly golden.

        Great news! We left it in the crockpot for 4 additional hours on low and it tastes fantastic! I can’t wait to have a bowl of it this afternoon during the snow/ice storm we’re expecting.

      I’ve tried freezing potato soups in the past and I don’t like the way they thaw, they separate.

    • Kris

      I have a Tuscan Soup that has evaporated milk and I freeze it. When I thaw it, it looks to be curdled but, after reheating it in the microwave, it surprisingly seems to smooth out again. I’d try freezing and reheating just to see how it comes out for you.

    First time making soup in a crock pot. Everyone loved it. The only difference was I used caramelized onions, sauteed in the bacon fat. I also added extra cheese and sour cream. :) Potatoes cooked perfectly, actually in 3.5 hours on high.
