- Use half-and-half instead of heavy cream for a lighter texture without sacrificing creaminess.
- If you prefer a smoother soup, blend it more thoroughly with an immersion blender.
Storage
Store leftover soup in an airtight container in the refrigerator for up to 3 days. To reheat, warm it gently on the stove over medium heat, stirring occasionally until heated through. You may need to add a splash of broth or cream to loosen the consistency if it thickens during storage.

FAQs
Can I make this soup without a slow cooker?
Yes, you can prepare this soup on the stovetop by simmering the ingredients in a large pot over medium heat for about 45 minutes, or until the potatoes are tender. Then proceed with mashing and adding the cream and butter as instructed.
Is it possible to freeze Cajun Potato Soup?
Freezing this soup is not recommended because the cream and potatoes may separate or become grainy after thawing. It’s best to enjoy it fresh or refrigerate for a few days.
