Cajun Potato Soup is the dinner I turn to when I crave comfort food with a bold kick. With plump andouille sausage, tender potatoes, and just the right dose of heat, this creamy soup combines rich flavors with Cajun flair. It comes together easily, making it perfect for chilly nights or whenever you need something that satisfies in every way.
I tasted a version of this on a road trip through Louisiana and it instantly became a favorite. My family loves how deeply flavored and hearty it is and they ask for it year round not just in the cold months.

Step-by-Step Instructions
- Sauté the Sausage:
- In a large heavy pot over medium heat add the vegetable oil and swirl to coat the bottom. Once the oil is shimmering lay in the sausage slices in a single layer. Let them cook undisturbed for about two minutes then stir and brown the other sides. When well caramelized after three to four minutes remove the sausage to a plate leaving the flavorful oil in the pot.
- Cook the Vegetables:
- With the pot still over medium heat add the diced onion celery and red bell pepper. Scrape up any brown bits from the sausage with your spoon and stir the vegetables well. Cook for six to eight minutes stirring often until they are softened and starting to become golden. At this point stir in the minced garlic and cook for one minute just until fragrant never longer so the garlic does not burn.
- Simmer the Soup Base:
- Add the Cajun seasoning kosher salt black pepper paprika and cayenne pepper directly into the pot of vegetables. Stir the spices in well so they coat the veggies and release their aroma. Pour in the chicken broth and carefully add the cubed potatoes. Bring to a gentle simmer then reduce the heat to maintain the simmer. Cover loosely and let the potatoes cook for twenty to twenty five minutes until fork tender and easy to break apart.
- Finish and Serve:
- Return the browned sausage and any juices to the pot. Pour in the heavy whipping cream and scatter the shredded cheddar cheese across the surface. Stir gently and allow the soup to simmer five more minutes so the cheese melts fully and everything becomes thick and velvety. Taste and adjust seasoning if needed. Ladle into bowls and sprinkle with chopped parsley for a bright finishing touch.

I have always been drawn to the smoky snap of a sliced andouille sausage. Its deep flavor transforms any soup but in this dish it shines against the mild potatoes and creamy broth. My family always gathers in the kitchen when this is bubbling on the stove and those spicy aromas never fail to bring smiles.
Storage Tips
Cajun Potato Soup can be cooled and stored in airtight containers in the refrigerator for up to four days. The flavors actually deepen overnight which makes for fantastic leftovers. If you plan to freeze the soup leave out the cream and cheese then add them when reheating to keep the texture smooth.
Ingredient Substitutions
If you cannot find andouille sausage try another smoked spicy sausage like kielbasa or even chorizo for a twist. Sweet potatoes can be swapped for russets for a little extra sweetness and color. If cheddar is not available a blend of Monterey Jack and mozzarella also melts well and tastes great.
Serving Suggestions
This soup is hearty enough to be a meal on its own but it pairs beautifully with warm crusty bread or a simple green salad. Sometimes I serve it with cornbread or sprinkle extra cheese and green onions on top for added color and flavor.

Cajun cuisine grew from French Acadian settlers living in the swamps and prairies of Louisiana.
