Ingredients
Instructions
-
In a large soup pot or Dutch oven, heat the butter and olive oil over medium heat. Add the diced onion, green bell pepper, and celery. Sauté for 5–7 minutes, until the vegetables are soft and the onion is translucent. Stir in the garlic and cook for another 30 seconds until fragrant.
-
This "holy trinity" of onion, pepper, and celery forms the classic Cajun flavor base.
-
Stir in the smoked paprika, Cajun seasoning, dried thyme, black pepper, and optional cayenne. If you’re using sausage, add it now. Let it brown slightly for 3–5 minutes to build flavor and render out fat.
-
Tip: For a meatless version, skip the sausage — the soup still packs tons of flavor!
-
Add the diced potatoes and pour in the chicken broth. Stir to combine, scraping up any browned bits from the bottom. Bring the mixture to a boil over high heat, then reduce the heat to medium-low. Cover and simmer for 20–25 minutes, or until the potatoes are very tender when pierced with a fork.
-
If you want a thicker soup, remove about 1 cup of cooked potatoes and mash them, then return to the pot to thicken the broth naturally.
-
(Optional) For an extra creamy base, make a slurry by whisking 2 tablespoons flour with ¼ cup cold water or broth until smooth. Stir this into the simmering soup and cook for 2–3 more minutes.
-
Next, stir in the heavy cream or half-and-half. Let the soup simmer gently for another 5–10 minutes, but do not bring to a full boil after adding the cream.
-
Taste and adjust the seasoning with salt and additional Cajun spice, if needed.
-
For a cheesy version, stir in the shredded cheddar just before serving and let it melt into the soup. It adds richness and balances the heat of the spices beautifully.

Cajun Potato Soup Tips, Tricks & Serving Ideas
Cajun Potato Soup is a rich, hearty, and boldly seasoned dish that brings the warmth of Louisiana to your bowl. It's perfect for cool weather or anytime you're craving comfort food with a little kick. Here’s how to make your Cajun Potato Soup shine—with tips on ingredients, flavor-building, and creative ways to serve it.
Building Deep Cajun Flavor
Start with the Cajun flavor base: the “holy trinity” of chopped onions, bell peppers, and celery sautéed in butter or oil. This step is essential for authentic flavor. Be sure to let the vegetables soften and begin to caramelize slightly—this will deepen the soup’s flavor.
Add minced garlic and a smoky Cajun seasoning blend. You can use store-bought Cajun spice, but for better control over the heat and salt levels, consider making your own with a mix of paprika (smoked is best), cayenne, garlic powder, onion powder, oregano, thyme, black pepper, and a bit of salt.
Use russet or Yukon gold potatoes for a balance of starchiness and creaminess. Cube them evenly so they cook uniformly. Simmer the potatoes in chicken broth (or vegetable broth) until fork-tender, and partially mash some in the pot for a creamy texture without needing heavy cream.
To make the soup creamy and rich, stir in some heavy cream, half-and-half, or a dairy-free alternative like full-fat coconut milk. For a thicker soup, you can also create a roux (a mix of flour and fat) or blend a portion of the cooked potatoes.
Protein & Add-Ins
Add cooked Cajun-style sausage (like andouille or smoked kielbasa) for a meaty, spicy punch. You can also add shredded chicken, shrimp, or even crumbled bacon for variety.
Want to stretch the meal? Stir in frozen corn, chopped spinach, or cooked rice to make the soup even more filling. A dash of hot sauce or a squeeze of lemon right before serving can help balance richness with brightness.
Tips for Serving
Cajun Potato Soup is best served hot and hearty. Garnish with chopped green onions, parsley, shredded cheddar cheese, or even a dollop of sour cream for contrast. Toasted bread or cornbread on the side makes for a satisfying meal.
For a Cajun party or potluck, serve the soup in small bowls or mugs with toppings in individual dishes so everyone can customize their own.
To make this soup ahead of time, prep all the veggies and sausage in advance, or cook the soup and refrigerate for up to 3 days. It tastes even better the next day as the flavors meld. Just reheat gently on the stovetop and thin with a splash of broth if needed.
Servings
This soup typically serves 6–8 people, depending on portion size. It’s easily doubled for a crowd or portioned into freezer-safe containers for future meals.
Garnish and Serve
Ladle the soup into bowls and top with chopped parsley or sliced green onions for color and a fresh bite. Serve hot with crusty bread, cornbread, or even over cooked white rice for a heartier meal.
Tips and Variations
- Make it vegetarian by using vegetable broth and skipping the sausage.
- Add chopped kale or spinach at the end for extra greens.
- Use leftover mashed potatoes to thicken the soup quickly.
- Want more heat? Add a few dashes of hot sauce or diced jalapeño when cooking the aromatics.
Storage
This soup stores beautifully. Refrigerate leftovers in an airtight container for up to 4 days. It can also be frozen for up to 2 months — just reheat gently and stir in fresh cream or milk to bring it back to its creamy consistency.
Whether you’re a fan of Southern cuisine or simply looking for a bold, comforting bowl of goodness, Cajun Potato Soup delivers on every front. It’s spicy, creamy, and packed with soul-warming flavor — just like Louisiana intended.

Frequently Asked Questions
What makes Cajun Potato Soup different from regular potato soup?
Cajun Potato Soup is known for its bold flavors, thanks to traditional Cajun seasonings like paprika, cayenne, garlic powder, thyme, and sometimes smoked sausage.
It often includes onions, bell peppers, and celery—the “holy trinity” of Cajun cooking. This gives it a spicy, savory depth that sets it apart from classic creamy potato soup.
Is Cajun Potato Soup spicy?
It can be, but the level of heat is adjustable. Most recipes use Cajun seasoning blends, which often include cayenne pepper. If you prefer mild spice, you can reduce the cayenne or use a low-sodium Cajun seasoning. For a kick, you can add hot sauce or smoked andouille sausage.
What kind of potatoes work best in this soup?
Waxy potatoes like Yukon Golds or red potatoes are ideal because they hold their shape well during cooking. However, if you prefer a thicker, more rustic texture, russet potatoes break down slightly and help naturally thicken the soup.
Can Cajun Potato Soup be made ahead or frozen?
Yes, it stores well in the refrigerator for up to 3–4 days. For freezing, it’s best to leave out dairy (like cream or cheese) until reheating, as those can separate. Let it cool completely, then store in airtight containers. When reheating, stir in any creamy elements for a fresh taste and texture.
