Ingredients:
- 1 tablespoon vegetable oil
- 1 ring (13.5 ounces) andouille sausage, sliced into ¼-inch rounds
- 1 large onion, diced (about 1 cup)
- ½ cup diced celery (about 1 rib)
- ½ red bell pepper, seeded and diced
- 2 teaspoons garlic, minced
- 1 teaspoon Cajun seasoning
- ½ teaspoon kosher salt
- ½ teaspoon black pepper
- ½ teaspoon paprika
- ¼ teaspoon cayenne pepper
- 4 cups (960 g) chicken broth
- 4 large russet potatoes, peeled and cubed
- ½ cup (119 g) heavy whipping cream
- 1 cup (113 g) mild cheddar cheese, shredded
Sautéing the Sausage and Aromatics
- Begin extract by heating the vegetable oil in a large pot or Dutch oven over medium-high heat. Once the oil is shimmering, add the sliced andouille sausage. Cook the sausage for about 5-7 minutes, stirring occasionally, until it is nicely browned and has rendered some of its flavorful fat. This initial browning is crucial for developing a deep, smoky flavor that will infuse the entire Cajun Potato Soup. Using a slotted spoon, remove the browned sausage from the pot and set it aside on a plate, leaving the rendered fat in the pot. We’ll be adding the sausage back later.
- Reduce the heat to medium. To the flavorful sausage drippings remaining in the pot, add the diced onion, diced celery, and diced red bell pepper. This classic combination of vegetables, known as a “holy trinity” in Cajun and Creole cooking, forms the aromatic foundation of our soup. Cook these vegetables for 8-10 minutes, stirring frequently, until they are softened and the onion has become translucent. Don’t rush this step; allowing the vegetables to soften properly will create a smoother soup base.
- Add the minced garlic to the pot with the softened vegetables. Cook for another minute, stirring constantly, until the garlic is fragrant. Be careful not to burn the garlic, as this can impart a bitter flavor to your soup. Immediately after the garlic is fragrant, add the Cajun seasoning, kosher salt, black pepper, paprika, and cayenne pepper. Stir well to coat the vegetables and toast the spices for about 30 seconds. Toasting the spices releases their essential oils and intensifies their flavor, which is key to achieving that authentic Cajun kick.
Building the Soup Base
- Pour the chicken broth into the pot, scraping the bottom with a wooden spoon to loosen any browned bits that may have stuck. These bits are full of flavor and will enhance the soup. Bring the mixture to a simmer.
- Add the peeled and cubed russet potatoes to the simmering broth. Ensure the potatoes are fully submerged in the liquid. Cover the pot and let the soup simmer gently for 15-20 minutes, or until the potatoes are fork-tender. You should be able to easily pierce a potato cube with a fork. Once the potatoes are tender, you have a couple of options for achieving your desired soup consistency. For a chunkier soup, you can leave the potatoes as they are. For a creamier, smoother soup, use an immersion blender to partially or fully blend the potatoes directly in the pot. Alternatively, you can carefully ladle about half of the soup, including the potatoes, into a regular blender and blend until smooth, then return it to the pot.
Finishing Touches and Serving
- Stir in the heavy whipping cream and the reserved browned andouille sausage into the soup. Let the soup heat through gently for another 5 minutes over low heat. Do not bring the soup to a rolling boil after adding the cream, as this can cause it to curdle. The gentle simmering will allow the flavors to meld beautifully and the soup to thicken slightly.
- Just before serving, stir in the shredded mild cheddar cheese. Continue to stir gently until the cheese is completely melted and incorporated into the soup, creating a wonderfully rich and creamy texture. Taste the soup and adjust seasonings if necessary, adding a pinch more salt or cayenne pepper if desired.
- Ladle the hot Cajun Potato Soup into bowls. For an extra touch, you can garnish with a sprinkle of fresh parsley or a dollop of sour cream. This hearty and flavorful soup is perfect for a chilly evening and is sure to become a favorite.

Frequently Asked Questions:
Can I make this soup ahead of time?
Absolutely! Cajun Potato Soup is even better the next day as the flavors have more time to meld. Simply store it in an airtight container in the refrigerator for up to 3-4 days. Reheat gently on the stovetop or in the microwave, adding a splash of broth or milk if it becomes too thick.
What if I don’t like spicy food? Can I reduce the heat?
Yes, you can easily adjust the spice level. Omit the cayenne pepper entirely if you prefer a mild soup. You can also reduce the amount of Cajun seasoning or opt for a milder blend. The heat from the sausage (if used) will also contribute, so consider that when making adjustments.
How can I make this soup vegetarian or vegan?
To make this Cajun Potato Soup vegetarian, simply omit the sausage and use vegetable broth. For a vegan version, use vegetable broth and ensure your Cajun seasoning is vegan-friendly. You can also substitute the dairy-based toppings (sour cream, milk) with vegan alternatives like cashew cream or coconut milk.
