Ingredients You’ll Need

This Cajun Potato Soup relies on straightforward, easy-to-find ingredients, each playing a vital role in delivering authentic flavor, creamy texture, and that irresistible spicy kick. Simple pantry staples come together with fresh veggies and sausage to create a dish that’s both comforting and exciting.

• Vegetable oil: The perfect neutral oil to brown the sausage and soften the vegetables without overpowering flavors.
• Andouille sausage (13.5 ounces): Sliced into thin rounds, it offers smoky, spicy depth that defines the Cajun character of the soup.
• Large onion: Adds sweetness and a mellow base flavor when diced and sautéed.
• Diced celery (½ cup): Introduces a subtle crunch and earthy freshness that balances the richness.
• Red bell pepper (½ piece): Brings a mild sweetness and vibrant red color to brighten the soup.
• Minced garlic (2 teaspoons): Essential for that fragrant kick that melds all the flavors together beautifully.
• Cajun seasoning (1 teaspoon): The heartbeat of this dish, lending a spicy, smoky blend of spices crucial for authentic taste.
• Kosher salt (½ teaspoon): Enhances and rounds out all the flavors.
• Black pepper (½ teaspoon): Adds just the right amount of subtle heat and complexity.
• Paprika (½ teaspoon): For warmth and a subtle smoky undertone.
• Cayenne pepper (¼ teaspoon): Delivers a gentle but noticeable kick, perfect for that Cajun punch.
• Chicken broth (4 cups): Creates a rich, savory base that ties the whole soup together.
• Russet potatoes (4 large): Peeled and cubed for creamy texture and hearty substance.
• Heavy whipping cream (½ cup): Gives luscious creaminess that softens the spices and enriches the soup.
• Mild cheddar cheese (1 cup shredded): Melts into the soup, adding gooey, comforting cheesiness.
• Fresh parsley: Chopped for garnish, it adds freshness and a burst of green color on top.

How to Make Cajun Potato Soup

Step 1: Brown the Sausage

Start by heating a tablespoon of vegetable oil in a large pot over medium heat. Add the sliced andouille sausage and cook it until it’s nicely browned, stirring occasionally. This step not only cooks the sausage but also releases all its smoky, spiced oils into the pot, building a flavorful foundation for your soup. Once browned, transfer the sausage to a plate and set it aside while you prepare the other ingredients.

Step 2: Sauté the Vegetables

Into the same pot, add diced onion, celery, and red bell pepper. Cook these veggies until they are softened and aromatic, about 5 to 8 minutes. This mixture creates a classic Cajun “trinity,” which is essential for that authentic depth of flavor. Toss in the minced garlic during the last minute of cooking so it doesn’t burn but fully releases its fragrance.

Step 3: Add Spices, Broth, and Potatoes

Next, sprinkle in the Cajun seasoning, kosher salt, black pepper, paprika, and cayenne pepper. Stir well to coat the sautéed veggies in these spices, allowing their complex flavors to bloom. Pour in the chicken broth and add the peeled, cubed russet potatoes. Bring the mixture to a gentle simmer, then reduce the heat and let it cook for 20 to 25 minutes, or until the potatoes become tender and start to break down, thickening the soup naturally.

Step 4: Finish with Sausage, Cream, and Cheese

Return the cooked sausage to the pot, stirring it in along with the heavy whipping cream and shredded cheddar cheese. Let everything simmer together for about 5 minutes until the cheese has melted perfectly into the creamy broth and the soup is hot throughout. This final step brings creaminess and a rich savory punch that makes the Cajun Potato Soup truly comforting and satisfying.

How to Serve Cajun Potato Soup

Garnishes

Your Cajun Potato Soup deserves an extra touch of freshness and color on top. I love sprinkling chopped parsley over each bowl. It adds a lovely herbaceous brightness that balances the richness and a pop of inviting green that makes the soup even more enticing. Don’t be shy to add a few extra grates of cheddar cheese or a swirl of cream if you like it even more indulgent.

Side Dishes

This soup pairs beautifully with bread designed to soak up all its delicious broth. Crusty French bread, buttery cornbread, or even garlic toast make perfect companions. A light, crisp green salad with a tangy vinaigrette also complements the creamy, spicy qualities of the soup by adding a refreshing crunch and acidity.

Creative Ways to Present

For a bit of fun and flair, serve the Cajun Potato Soup in hollowed-out small bread bowls for a rustic, cozy presentation. You can even sprinkle some extra cooked andouille sausage on top for a meaty burst with every bite. Garnishing with a few thinly sliced green onions or a dash of smoked paprika adds a nice finishing touch that impresses any guest.

Make Ahead and Storage

Storing Leftovers

Leftover Cajun Potato Soup tastes just as amazing the next day. Store it in an airtight container in the refrigerator for up to 3 days. The flavors actually have a chance to meld and deepen overnight, making it a perfect make-ahead meal for busy weeknights.

Freezing

If you want to keep the soup longer, it freezes quite well. Let the soup cool completely, then transfer to freezer-safe containers or heavy-duty zip-top bags. Frozen, it will stay good for up to 2 months. Keep in mind the cream and cheese might change texture slightly after freezing, but it’s still delicious.

Reheating

When reheating, do so gently on the stove over low to medium heat. Stir frequently to prevent scorching, and if the soup seems too thick, you can add a splash of chicken broth or water to loosen it back up. Avoid boiling as it can curdle the dairy components. A slow, careful reheat brings the Cajun Potato Soup right back to its creamy, flavorful glory.

FAQs

Can I make this Cajun Potato Soup vegetarian?

Absolutely! Just skip the andouille sausage and use vegetable broth instead of chicken broth. You might want to boost the smokiness by adding smoked paprika or smoked salt, and you could toss in some smoked tofu or mushrooms for texture.

What can I substitute for heavy cream?

If you want a lighter version, half-and-half or whole milk can work fine, but the soup won’t be as rich and creamy. For dairy-free options, coconut milk or cashew cream add creaminess with a mild flavor that pairs surprisingly well with Cajun spices.

How spicy is the soup? Can I adjust it?

The spice level is moderate, thanks to the Cajun seasoning and a dash of cayenne pepper. If you prefer less heat, simply reduce the cayenne or omit it. For a bolder kick, feel free to add extra cayenne or chopped jalapeños when sautéing the veggies.

Can I use other types of potatoes?

Russet potatoes are ideal because they break down nicely and thicken the soup, but Yukon Golds or red potatoes can also work if you prefer a chunkier texture. Just adjust cooking time to ensure they’re tender.

Is this soup gluten-free?

Yes! All the ingredients here are naturally gluten-free. Just be sure your Cajun seasoning and sausage do not contain any added gluten ingredients. Always check labels if you’re cooking for someone with gluten sensitivities.
