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 i do the second part with the flour and everything else after the 8 hours on low?

  • Christine

    Could I use turkey bacon and Greek yogurt in place of the sour cream for healthier options or would that change the taste alot?

    • Jaclyn

      I think that should be fine, it won’t be quite as rich but Greek yogurt is a great sub for sour cream and turkey bacon for a healthier alternative to the regular.

    I only have a 3.5 qt cooker, so I took your advice and halved the ingredients but left all cooking times the same. It was so good! The flavor is amazing. The only complaint was that it was a bit grainy – kind of a ā€œmalt o mealā€ quality. Any idea what may have caused this? Other than that, though, it was delicious! A new family favorite!

      I would cook it longer because the potatoes/veggies probably weren’t tender enough which would cause an off texture. Hopefully that helps!

    Thank you for the recipe! I have made it twice, and both with amazing results. The first time, I did not have evaporated milk so I just put in half & half and gave everything a good stir. Additionally, I didn’t have time to make the roux, so I took some of the heated chicken broth from the crockpot and dumped in a few tablespoons of flour, stirred until it combined, and then placed the mixture back into the soup and gave everything a big stir again. Two thumbs up!

    I made the soup again last night (I realised the first time I omitted the sour cream at the end) and this time I added heavy cream, and again did the same thing with the roux as the first time. It was delish!

    Thank you!

  • Laura

    When do you add the butter/flour?! After the 8 hrs ?? Can you do it before ?

    • Jaclyn

      Jaclyn Bell

      You add it after the 8 hours, I wouldn’t add it before or it will likely separate and not thicken the soup properly.

  • RoseAnna

    did anybody else have their evaporated milk turn into small chunks in their crockpot? Is this normal???

    • Jaclyn

      Jaclyn Bell

      Not sure why that would have happened, it may have cooked too long or gotten too hot?

  • Madison

    I saw a few people comment about preparing this ahead of time! I always prepare crockpot meals on Sunday for the week. For this one, there’s chicken broth in the first few ingredients, so I prepared a Ziplock (on Sunday) with the potatoes and onion and chicken broth and everything still looked fresh today (on Tuesday) when I put it in the crockpot. I waited until today to do the evaporated milk. Everything seems to be going well, hah! Looking forward to it tonight!!

  • Katelyn

    Did you use three 14.5 oz cans of chicken broth? Or 14.5 oz total?? I only have 32oz and don’t know if that’s enough!

    • Jaclyn

      Jaclyn Bell

      It is three of the 14.5 oz cans, you could sub water for the last 14.5 oz can and bouillon or chicken base if you have it, if you don’t it should be a big deal because you still have the two cans.
