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, 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, cubed
- ½ cup (119 g) heavy whipping cream
- 1 cup (113 g) mild cheddar cheese, shredded
Getting Started: Sautéing the Aromatics and Sausage
1. Begin by preparing your ingredients. Ensure your andouille sausage is sliced into uniform ¼-inch rounds. Dice the onion, celery, and red bell pepper into roughly the same size pieces to ensure even cooking. Mince your garlic. Peeling and cubing the potatoes is the final prep step before we start cooking. Having everything ready to go, often referred to as “mise en place” in professional kitchens, makes the cooking process much smoother and more enjoyable.
2. Heat the vegetable oil in a large, heavy-bottomed pot or Dutch oven over medium-high heat. Once the oil is shimmering, add the sliced andouille sausage. Cook the sausage for about 3-5 minutes per side, or until it’s nicely browned and has rendered some of its flavorful fat. This browning process is crucial for developing deep flavor. Don’t overcrowd the pot; if necessary, cook the sausage in batches. Once browned, use a slotted spoon to remove the sausage from the pot and set it aside on a plate, leaving the rendered fat in the pot. This fat is liquid gold and will be the base for our sautéed vegetables.
Building the Flavor Base
3. Reduce the heat to medium and add the diced onion, celery, and red bell pepper to the pot with the sausage drippings. Cook, stirring occasionally, for about 6-8 minutes, or until the vegetables have softened and the onion is translucent. This aromatic mirepoix (the combination of onion, celery, and bell pepper in Cajun cooking) is the foundation of flavor for many dishes. Scrape the bottom of the pot to loosen any browned bits left from the sausage – these bits are packed with flavor. Now, add the minced garlic to the pot and cook for another minute until fragrant, being careful not to burn it, as burnt garlic can turn bitter.
4. It’s time to introduce our spice blend. Stir in the Cajun seasoning, kosher salt, black pepper, paprika, and cayenne pepper. Cook for about 1 minute, stirring constantly, until the spices are fragrant. Toasting the spices briefly in the hot fat amplifies their flavors and aromas, creating a more complex and vibrant taste profile for your soup. The combination of these spices will bring that signature Cajun warmth and heat. Adjust the cayenne pepper to your preference; if you like it spicier, feel free to add a little more.
Simmering to Perfection
5. Pour in the chicken broth and bring the mixture to a simmer, scraping the bottom of the pot again to ensure all the flavorful bits are incorporated. Add the peeled and cubed russet potatoes to the pot. The russet potatoes are ideal for this soup because their starch content helps to thicken the soup naturally as they cook. Bring the soup back to a gentle simmer, then reduce the heat to low, cover the pot, and let it cook for about 15-20 minutes, or until the potatoes are fork-tender. You want them to be cooked through but not falling apart completely.
6. Once the potatoes are tender, you have a couple of options for achieving your desired soup consistency. For a chunkier soup, you can simply mash some of the potatoes against the side of the pot with your spoon to release some starch and thicken the broth. For a creamier, smoother soup, you can use an immersion blender to partially or fully blend the soup directly in the pot. Be cautious when using an immersion blender and ensure the blades are fully submerged. Alternatively, you can carefully ladle about 2-3 cups of the soup into a regular blender (do this in batches if necessary, and never fill a blender more than halfway with hot liquid) and blend until smooth, then return it to the pot.
Finishing Touches for Creaminess and Richness
7. Stir in the heavy whipping cream and the reserved cooked andouille sausage. Allow the soup to heat through gently for another 5 minutes, but do not let it boil once the cream has been added, as this can cause it to curdle. The cream will lend a luxurious, velvety texture to the soup, beautifully balancing the spices.
8. Finally, stir in the shredded mild cheddar cheese. Continue stirring until the cheese is completely melted and the soup is smooth and creamy. This final addition of cheese not only adds another layer of creamy richness but also imparts a subtle cheesy flavor that complements the other ingredients wonderfully. Taste the soup and adjust seasonings if necessary. You might find you need a touch more salt or a pinch more cayenne for extra heat. Serve your delicious Cajun Potato Soup hot, garnished with extra shredded cheese, a dollop of sour cream, or fresh chopped parsley if desired. Enjoy the comforting, spicy goodness!

Frequently Asked Questions:
Can I make this soup ahead of time?
Absolutely! This Cajun Potato Soup actually tastes even better the next day as the flavors have more time to meld. Simply let it cool completely, then store it in an airtight container in the refrigerator. Reheat gently on the stovetop over low heat, adding a splash of broth or water if it becomes too thick.
What kind of potatoes are best for this soup?
Russet potatoes are my go-to for this recipe. They break down beautifully when cooked, contributing to the soup’s creamy texture. Yukon Gold potatoes are another excellent choice, offering a slightly waxy texture that holds its shape a little better while still becoming tender.
How spicy is this soup?
The spice level can be adjusted to your preference. The base recipe uses Cajun seasoning, which typically has a moderate amount of heat. If you prefer it milder, use a Cajun seasoning blend with less spice or reduce the amount slightly. For a spicier soup, add a pinch of cayenne pepper or a dash of your favorite hot sauce.
