- ½ cup diced celery, about 1 rib
- ½ red bell pepper, seeded, diced
- 2 teaspoons garlic, minced
- 1 teaspoon Cajun seasoning
- ½ teaspoon kosher salt
- ½ teaspoon black pepper
- ½ teaspoon paprika

Cooking Instructions
This soup comes together quite easily, and the aroma that fills your kitchen as it simmers is absolutely divine. The key to its depth of flavor is building a good base, so don’t rush those initial sautéing steps!
- First things first, let’s get our foundational flavors going. Heat the tablespoon of vegetable oil in a large Dutch oven or heavy-bottomed pot over medium-high heat. Once the oil is shimmering, add the sliced andouille sausage. We want to get a nice sear on this spicy sausage, rendering out some of its delicious fat and infusing the oil with its smoky essence. Cook the sausage for about 5-7 minutes, stirring occasionally, until it’s browned and slightly crispy on the edges. Once it’s nicely browned, use a slotted spoon to remove the sausage from the pot and set it aside on a plate. Leave the rendered fat in the pot – this is liquid gold for our soup!
- Now, we’re going to build our aromatic base. To the same pot with the sausage drippings, add the diced onion, diced celery, and diced red bell pepper. Sauté these vegetables over medium heat for about 8-10 minutes, or until they’ve softened and the onion is translucent. This is often referred to as the “holy trinity” in Cajun and Creole cooking (onion, celery, and bell pepper), and it forms the flavor backbone of so many delicious dishes. Stir them frequently to prevent sticking. Once the vegetables have softened, add the minced garlic and cook for another minute until fragrant. Be careful not to burn the garlic, as it can turn bitter.
- It’s time to introduce our spice blend. Sprinkle the Cajun seasoning, kosher salt, black pepper, paprika, and cayenne pepper over the softened vegetables. Stir everything together well and cook for about 1-2 minutes more, allowing the spices to bloom and release their full aroma. This step really intensifies the flavors and creates a wonderfully fragrant mixture. You should be able to smell the wonderful, complex aroma of the spices mingling with the vegetables and sausage drippings.
- Next, we’ll add our liquids and potatoes. Pour in the 4 cups of chicken broth, scraping the bottom of the pot with your spoon to loosen any browned bits that may have stuck there – these bits are packed with flavor! Add the cubed russet potatoes to the pot. Russet potatoes are perfect for this soup because they break down slightly as they cook, helping to thicken the soup naturally. Bring the mixture to a boil, then reduce the heat to low, cover the pot, and let it simmer for about 15-20 minutes, or until the potatoes are fork-tender. Check on them periodically to ensure they aren’t sticking.
- This is where our soup transforms into pure creamy deliciousness! Once the potatoes are tender, stir in the reserved cooked andouille sausage. Then, gradually stir in the ½ cup of heavy whipping cream. Allow the soup to heat through gently for a few more minutes, but don’t let it come to a rolling boil once the cream is added, as it could curdle. Finally, stir in the 1 cup of shredded mild cheddar cheese. Keep stirring until the cheese is completely melted and the soup is smooth and creamy. Taste and adjust seasonings if necessary. If you prefer a thicker soup, you can mash a few of the potato cubes against the side of the pot with your spoon.
Serve this comforting Cajun Potato Soup hot, perhaps with a sprinkle of fresh chopped parsley or chives for a touch of freshness. Enjoy the rich, smoky, and slightly spicy flavors that make this soup so incredibly special!

Frequently Asked Questions:
Can I make this soup ahead of time?
Absolutely! Cajun Potato Soup often tastes even better the next day as the flavors have more time to meld. Store it in an airtight container in the refrigerator for up to 3-4 days. Reheat gently on the stovetop, adding a splash of broth or milk if it has thickened too much.
What if I can’t find Cajun seasoning?
No problem! You can create your own DIY Cajun seasoning blend. A common mixture includes paprika, cayenne pepper, garlic powder, onion powder, dried oregano, dried thyme, and salt. Adjust the cayenne to your desired spice level.
Is this soup spicy?
The spiciness of this Cajun Potato Soup is adjustable. The primary spice comes from the Cajun seasoning, which typically has a moderate level of heat. If you prefer a milder soup, use a Cajun seasoning blend with less cayenne pepper, or simply reduce the amount you add. For a spicier soup, increase the cayenne pepper or add a pinch of extra red pepper flakes.
