Ingredients You’ll Need

Gathering the ingredients for Cajun Potato Soup couldn’t be easier, and each element adds its own magic: texture from the potatoes, smoky notes from the sausage, creaminess from cheese and cream, and a punch of Cajun seasoning. Here’s what you’ll want on hand to create the deep, delicious flavors this soup is known for:

• Vegetable oil: Heats up quickly and helps brown the sausage for that essential savory base.
• Andouille sausage (13.5 ounces, sliced): Smoky, spicy, and essential for authentic Cajun flair—slice it into hearty coins.
• Onion (1 large, diced): Adds sweetness and depth when sautéed to soften.
• Celery (½ cup, diced): Gives a fresh crunch and gentle aroma that balances the heat.
• Red bell pepper (½, diced): For pops of color and subtle sweetness throughout the soup.
• Garlic (2 teaspoons, minced): Brings unmistakable savory warmth—don’t skimp on the garlic!
• Cajun seasoning (1 teaspoon): The heart of this recipe, infusing every bite with iconic Southern spice.
• Kosher salt (½ teaspoon): Enhances all the flavors without overpowering them.
• Black pepper (½ teaspoon): A gentle heat that works beautifully with the other spices.
• Paprika (½ teaspoon): Adds smoky undertones and gorgeous color.
• Cayenne pepper (¼ teaspoon): For that extra kick that separates a good soup from a great one!
• Chicken broth (4 cups): Lends body to the soup and ties all the flavors together.
• Russet potatoes (4 large, peeled and cubed): The star ingredient—rich and starchy, they create the perfect creamy base.
• Heavy whipping cream (½ cup): Just a splash transforms the broth into silky perfection.
• Mild cheddar cheese (1 cup, shredded): Melts seamlessly for a cheesy finish and boost of richness.
• Parsley (chopped, for garnish): A sprinkle of green freshness to brighten every bowl.

How to Make Cajun Potato Soup

Step 1: Brown the Andouille Sausage

Begin by heating your vegetable oil in a large pot over medium heat. Once it’s shimmering, toss in the sliced andouille sausage. Let it sizzle and caramelize for about 3-4 minutes, stirring occasionally—this step infuses the oil and, ultimately, the soup with that signature smoky, spicy depth. Once the sausage is beautifully browned, scoop it out and set it aside for later (try not to sneak too many bites!)

Step 2: Sauté the Veggies

In the same pot, let the leftover sausage drippings work their magic as you add diced onion, celery, and red bell pepper. Stir and let everything soften for 5-8 minutes to create a savory, fragrant foundation. Just before the veggies are done, toss in the minced garlic and cook for one more minute—this unlocks its sweet, mellow flavor.

Step 3: Layer in Cajun Spices and Potatoes

Next, sprinkle in the Cajun seasoning, kosher salt, black pepper, paprika, and cayenne. Stir to coat the veggies, letting those spices bloom and toast for a moment. Add the chicken broth and the peeled, cubed potatoes. Stir everything together, reduce the heat, and let the soup simmer gently for 20-25 minutes. The potatoes should be fork-tender, almost melting, and the broth will start to thicken deliciously.

Step 4: Add Cream, Cheese, and Sausage

Return the browned sausage to the pot, then pour in the heavy whipping cream and sprinkle in the mild cheddar cheese. Let the Cajun Potato Soup bubble on low for another 5 minutes—just long enough for the cheese to melt into silk and the sausage to reheat, making the soup decadently creamy and insanely aromatic.

Step 5: Finish and Serve

Stir one last time, then give your soup a taste for seasoning—add a pinch more salt or cayenne if you crave more heat. Ladle the Cajun Potato Soup into bowls, and garnish with lots of freshly chopped parsley for color and brightness. Serve warm and watch it disappear!

How to Serve Cajun Potato Soup

Garnishes

An irresistible bowl starts with fresh chopped parsley sprinkled on top, but you can take it further—think sliced scallions, extra cheddar, a dollop of sour cream, or even homemade seasoned croutons for crunch. Each garnish complements the soup’s velvety texture and spicy undertones beautifully.

Side Dishes

Cajun Potato Soup pairs perfectly with a thick slab of crusty bread or a golden cornbread muffin, just begging to be dunked. A crisp green salad tossed with a tangy vinaigrette adds contrast, while roasted okra or sautéed greens are ideal for keeping things Southern and balanced.

Creative Ways to Present

For fun, try serving Cajun Potato Soup in small bread bowls or shot glasses as mini appetizers at your next gathering. Want to impress? Swirl a touch of hot sauce and a sprinkle of extra cheddar cheese on top just before serving. You could even offer a toppings bar so everyone can make their bowl their own masterpiece!

Make Ahead and Storage

Storing Leftovers

After cooling the soup to room temperature, transfer leftovers into airtight containers and refrigerate for up to four days. The flavors deepen overnight, making Cajun Potato Soup even more unforgettable the next day.

Freezing

If you’re planning ahead, this soup freezes beautifully. Just pack it in freezer-safe containers, leaving a bit of room for expansion, and freeze for up to three months. Thaw overnight in the fridge before reheating so the texture stays just right.

Reheating

Warm up Cajun Potato Soup gently over low heat on the stovetop, stirring occasionally to avoid sticking or separating. If it’s thickened up in the fridge, add a splash of broth or cream to bring back its silky smoothness.

FAQs

Can I use a different type of sausage?

Absolutely, smoked kielbasa or chorizo make fantastic substitutes if you can’t find andouille. Just keep in mind each will subtly change the soup’s flavor profile, so pick what you love most!

Is Cajun Potato Soup very spicy?

The base recipe delivers a gentle warmth, not overwhelming heat. For a milder version, reduce or skip the cayenne pepper; for more kick, add extra to taste or offer hot sauce on the side.

Can I make this soup vegetarian?

Definitely! Skip the sausage, use vegetable broth, and boost the smoky flavor by adding smoked paprika or a few drops of liquid smoke. Smoked tofu or tempeh cubes are a tasty veggie protein swap.

How can I make Cajun Potato Soup thicker?

Simply mash a portion of the cooked potatoes directly in the pot with a spoon or potato masher. This releases their starch and thickens the broth to luscious perfection!

What potatoes work best for this recipe?

Russet potatoes really are the best for Cajun Potato Soup—they’re starchy and break down just enough to make the soup silky. Yukon Golds work in a pinch, but avoid waxier varieties for optimal creaminess.
