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
Cooking the Base
Step 1: Searing the Sausage and Building Flavor
Let’s start by getting some fantastic flavor built into our Cajun Potato Soup. Heat the vegetable oil in a large pot or Dutch oven over medium-high heat. Once the oil is shimmering, add your sliced andouille sausage. You want to cook this sausage for about 5-7 minutes, stirring occasionally, until it’s nicely browned and has released some of its delicious, spicy fat. This rendered fat is going to be the flavor foundation for our entire soup, so don’t rush this step! Once the sausage is browned, use a slotted spoon to remove it from the pot and set it aside on a plate lined with paper towels. This will allow some of the excess grease to drain off. Don’t discard the grease left in the pot – that’s pure gold!
Step 2: Sautéing the Aromatics
Now that our sausage has done its job, it’s time to add the aromatic vegetables to that flavorful pot. Reduce the heat to medium. Add the diced onion, diced celery, and diced red bell pepper to the pot. Cook these vegetables for about 8-10 minutes, stirring frequently, until they have softened and the onion is becoming translucent. This process, called sautéing, gently cooks the vegetables and coaxes out their natural sweetness. If at any point the bottom of the pot starts to look dry, you can add a tiny splash more vegetable oil or even a tablespoon of chicken broth. After the vegetables have softened, stir in the minced garlic and cook for another minute until it’s fragrant. Be careful not to burn the garlic, as it can become bitter.
Simmering the Soup
Step 3: Blooming the Spices and Adding Liquids
It’s time to infuse our soup with all those wonderful Cajun spices. Add the Cajun seasoning, kosher salt, black pepper, paprika, and cayenne pepper to the pot with the softened vegetables. Stir everything together and cook for about 1 minute, allowing the spices to toast slightly in the residual heat and oil. This blooming process intensifies their flavors and aroma. Now, pour in the chicken broth. Scrape the bottom of the pot with your spoon to loosen any browned bits of sausage and vegetable that may have stuck. These bits are packed with flavor and will dissolve into the broth, making your soup even richer. Bring the mixture to a boil.
Step 4: Cooking the Potatoes
Once the broth is boiling, carefully add the peeled and cubed russet potatoes to the pot. Make sure the potatoes are mostly submerged in the liquid. Reduce the heat to low, cover the pot, and let the soup simmer gently for about 15-20 minutes, or until the potatoes are fork-tender. You should be able to easily pierce a potato cube with the tip of a fork. Avoid overcooking the potatoes, as they can become mushy. Stir occasionally to ensure even cooking. This is also a good time to taste the broth and adjust the seasoning if you feel it needs a little more salt or spice. Remember, you can always add more, but you can’t take it away!
Finishing Touches
Step 5: Creaming and Cheesy Goodness
Now for the creamy, decadent part of our Cajun Potato Soup. Once the potatoes are tender, stir in the heavy whipping cream. Allow the soup to heat through gently for a couple of minutes, but do not bring it back to a rolling boil after adding the cream, as it can sometimes curdle. The soup should thicken slightly as it heats. Return the reserved browned andouille sausage slices to the pot. Finally, stir in the shredded mild cheddar cheese. Continue to stir until the cheese is completely melted and incorporated into the soup, creating a wonderfully creamy and cheesy texture. This makes the soup incredibly rich and satisfying. Ladle the hot Cajun Potato Soup into bowls, making sure each serving gets plenty of sausage and creamy broth. Garnish with extra shredded cheese or a sprinkle of fresh parsley if desired.

Frequently Asked Questions:
How can I make this Cajun Potato Soup spicier?
To increase the heat, you can add more cayenne pepper, a pinch of red pepper flakes along with the other spices, or even a dash of your favorite hot sauce at the end of cooking. You could also incorporate some diced jalapeños or serrano peppers when sautéing the onions and celery.
Can I make this soup ahead of time?
Yes, absolutely! The Cajun Potato Soup reheats beautifully. In fact, the flavors often meld and deepen overnight. Store it in an airtight container in the refrigerator for up to 3-4 days. When reheating, you may need to add a little extra broth or water to reach your desired consistency.
What type of potatoes are best for this soup?
While Yukon Golds are excellent for their creamy texture and ability to hold their shape, Russets are also a great choice, especially if you prefer a thicker, starchier soup. You can even use a combination of both for a delightful balance.
