Ingredients You’ll Need

With just a handful of pantry staples and a couple of fresh ingredients, you’ll bring the vibrant, spicy-satisfying character of Cajun Potato Soup to life. Each component plays a role in the final flavor, from the smokiness of sausage to the creamy finish of melted cheese.

Vegetable oil: Helps brown the sausage and sauté the veggies, giving warmth and richness to the base.
Andouille sausage: Classic Cajun flavor—smoky, spicy, and deeply savory—infuses every spoonful.
Onion: Provides soft sweetness and rounds out the soup’s base flavor.
Celery: Lends crunch and a subtle aromatic note to the vegetable mix.
Red bell pepper: Pops of color and sweetness make the soup vibrant and inviting.
Garlic: A small addition that brings a big punch of flavor to the party.
Cajun seasoning: The star spice blend—go homemade or use store-bought for zesty, smoky flavor.
Kosher salt: Just enough to balance and lift all the other flavors.
Black pepper: Adds depth with a subtle hint of heat.
Paprika: Boosts smokiness and gives the soup a warm hue.
Cayenne pepper: For those who love an extra spicy kick—add more or less to taste.
Chicken broth: Creates the soupy, savory base that binds all the flavors together.
Russet potatoes: Hearty and starchy; they break down perfectly for a creamy texture.
Heavy whipping cream: Adds rich, silky creaminess—absolute comfort in a bowl.
Mild cheddar cheese: Melts beautifully into the soup for a luscious finish.
Parsley: Fresh garnish for a burst of color and a hint of herbal freshness.

How to Make Cajun Potato Soup

Step 1: Brown the Andouille Sausage

Set a large pot over medium heat and add the vegetable oil. When it’s shimmering, scatter in the andouille sausage rounds. Sauté them, stirring occasionally, until they’re deeply browned and release their flavorful oils—this takes about 3 to 4 minutes. Once beautifully browned, scoop the sausage out and set it aside; that tasty, spiced oil left in the pot will anchor the rest of the soup’s flavor!

Step 2: Sauté the Vegetables

Toss the diced onion, celery, and red bell pepper into the pot. Cook, stirring occasionally, until the veggies soften and the onions turn translucent, about 5 to 8 minutes. Stir in the minced garlic and cook for an additional minute—it’ll make your kitchen smell absolutely amazing.

Step 3: Build the Soup Base

Now bring that Cajun flavor! Sprinkle in the Cajun seasoning, kosher salt, black pepper, paprika, and cayenne pepper. Pour in the chicken broth, then carefully add the cubed russet potatoes. Reduce the heat and let the mixture simmer gently for about 20 to 25 minutes, or until the potatoes are fork-tender and starting to break down a bit.

Step 4: Finish with Cream, Cheese, and Sausage

Return the browned sausage to the pot and stir in the heavy whipping cream and shredded cheddar cheese. Let everything simmer together for another 5 minutes, just until the cheese melts and the soup turns luxuriously creamy. Stir occasionally to prevent the cheese from sticking to the bottom.

Step 5: Garnish and Enjoy

Ladle the piping hot Cajun Potato Soup into bowls and shower with fresh chopped parsley. You’re ready to dig in—preferably with a hunk of crusty bread on the side!

How to Serve Cajun Potato Soup

Garnishes

Garnishing your Cajun Potato Soup is more than just a finishing touch—it adds freshness, color, and even another layer of flavor. Sprinkle bowls generously with chopped parsley, or add extra cheese or finely sliced green onions for a little extra zing. A dash of hot sauce is perfect for spice lovers!

Side Dishes

Warm, rustic bread (think French baguette or cornbread) is a dream companion for sopping up this creamy soup. Pair it with a crisp green salad dressed in a tangy vinaigrette to balance the richness, or serve alongside grilled corn for those real Southern vibes.

Creative Ways to Present

For something eye-catching, serve your Cajun Potato Soup in individual bread bowls or thick ceramic mugs. Add a swirl of cream or a sprinkle of Cajun seasoning on top before serving. If you’ve got leftovers, try pouring the soup over baked potatoes and topping with a few extra sausage rounds!

Make Ahead and Storage

Storing Leftovers

Let any leftover Cajun Potato Soup cool completely, then transfer to airtight containers. Kept in the fridge, it’ll stay fresh for up to 4 days. The flavors actually deepen and get even better overnight, making it a perfect meal prep soup!

Freezing

For longer storage, you can freeze Cajun Potato Soup. Just ladle it into freezer-safe containers, leaving a little room for expansion. While the cream and potatoes might change texture slightly after thawing, give it a good stir when reheating and you’ll still enjoy that comforting, spicy goodness.

Reheating

To reheat, warm the soup gently on the stovetop over medium-low heat, stirring often to prevent sticking. If it’s thicker than you like, add a splash of broth or milk. Microwave reheating also works for single servings—just do so in short bursts, stirring in between, for even heating.

FAQs

Can I make Cajun Potato Soup vegetarian?

Absolutely! Swap the andouille sausage for a plant-based alternative and use vegetable broth instead of chicken broth for a delicious vegetarian twist that still packs loads of flavor.

Is this soup spicy?

Cajun Potato Soup can be as spicy or as mild as you want! Adjust the amount of cayenne pepper or Cajun seasoning to match your taste. For a milder version, start with less and add more heat at the table.

What’s the best potato for this recipe?

Russet potatoes are preferred because they break down nicely and help thicken the soup, but Yukon Golds also work if you prefer a slightly creamier texture with a bit more bite.

Can I use a different sausage?

Yes! While andouille gives authentic Cajun flavor, smoked sausage or chorizo also taste great. Just aim for something with a smoky, savory profile to complement the soup.

How can I thicken Cajun Potato Soup?

If your soup feels a little thin, mash some of the potatoes against the side of the pot or use an immersion blender to puree a portion. The starch from the potatoes will do all the thickening work you need!

Final Thoughts

If you’re craving warm, bold comfort, Cajun Potato Soup promises to deliver every single time. Give this recipe a try—you might just find yourself making it on repeat, and sharing it with everyone you know!
