Slow Cooker Cajun Potato Soup Recipe FAQs
What type of potatoes should I use for this soup?
For the best texture in your Slow Cooker Cajun Potato Soup, I recommend using russet potatoes. They act as a natural thickener due to their high starch content and break down slightly as they cook, creating that creamy, hearty consistency. Avoid using waxy potatoes like red or Yukon since they won’t achieve the same smooth results.

How long can I store leftovers in the fridge?

Absolutely! You can freeze the soup without the dairy for up to 3 months. To freeze, allow the soup to cool completely, then portion it into airtight containers.

What if my soup is too thick after cooking?
If you find your soup has thickened more than you’d like, don’t worry! Just add a little extra chicken broth or milk while heating it on the stove, and stir until well combined. This will help return it to your preferred creamy consistency.
Is this soup gluten-free?
