Ingredients You’ll Need

Cajun Potato Soup is proof that magical flavors can come from everyday ingredients used in just the right way! Every item on this list has a purpose: from building a savory flavor base, to bringing color and gentle heat, to making the soup thick, creamy, and completely irresistible.

• Vegetable oil: The starting point for getting the sausage beautifully browned and for sautéing the aromatic veggies.
• Andouille sausage: Smoky, spicy sausage that is essential for that deeply flavorful Cajun character. Slice it on the thin side for even browning.
• Large onion: Brings natural sweetness and body to the base of the soup.
• Celery: Offers a subtle crunch and a classic savory undertone that balances the richness.
• Red bell pepper: Adds a lovely pop of color and a mild sweetness that contrasts the spice.
• Garlic: Fresh, minced garlic is a must for depth and that unmistakable Cajun aroma.
• Cajun seasoning: The flavor powerhouse here! Choose your favorite Cajun blend for authentic spice and warmth.
• Kosher salt: Enhances every ingredient and intensifies the overall savoriness of the soup.
• Black pepper: Adds a mild heat and depth—don’t skip it!
• Paprika: Offers earthy flavor and a gorgeous red hue.
• Cayenne pepper: Gives an extra kick for those who love true Cajun fire. Adjust to taste!
• Chicken broth: The flavorful liquid backbone of the soup—homemade or store-bought both work fine.
• Russet potatoes: The star of the dish; they break down enough to thicken the broth while still holding tender bites.
• Heavy whipping cream: Makes the soup rich and silky, melding all the flavors together.
• Mild cheddar cheese: Shredded cheese melts right in, boosting both creaminess and sharp flavor.
• Parsley: A fresh, herby finish that brightens up the whole bowl—don’t forget the garnish!

How to Make Cajun Potato Soup

Step 1: Brown the Sausage

Start by heating up your vegetable oil in a large pot over medium heat. Once it’s shimmering, throw in the sliced andouille sausage. Let the sausage cook, stirring occasionally, until it’s deliciously browned and smells irresistibly smoky—about 3 to 4 minutes. Scoop it out with a slotted spoon and set aside. This step builds layers of flavor, and those browned bits left behind are soup gold!

Step 2: Sauté the Veggies

In the same pot (don’t clean it, you want all that sausage flavor!), add your diced onion, celery, and red bell pepper. Cook, stirring occasionally, for about 5 to 8 minutes or until everything is softened and fragrant. Toss in the garlic and give it a quick stir—just a minute, so it doesn’t burn but releases all its magic.

Step 3: Build the Base and Simmer

Sprinkle in the Cajun seasoning, kosher salt, black pepper, paprika, and cayenne pepper. Give everything a good stir so the seasonings coat every veggie. Now add the chicken broth and the cubed potatoes. Bring everything to a gentle simmer, then reduce the heat. Let the mixture cook for 20 to 25 minutes, uncovered, until the potatoes are fork-tender and starting to break down around the edges.

Step 4: Finish with Cream, Cheese, and Sausage

Slide the cooked sausage back into the pot along with the heavy cream and the mild cheddar cheese. Let the soup simmer gently for about 5 more minutes, stirring occasionally, until the cheese melts into the broth and everything is piping hot. At this point, your Cajun Potato Soup will be thick, creamy, vibrant, and totally spoon-worthy.

Step 5: Garnish and Serve

Ladle the steaming soup into bowls and finish with a generous sprinkle of freshly chopped parsley. It’s ready to enjoy!

How to Serve Cajun Potato Soup

Garnishes

A big bowl of Cajun Potato Soup absolutely loves a little extra flourish! Chopped fresh parsley or green onions bring a pop of color and freshness. A sprinkle of more shredded cheddar or even a pinch of extra Cajun seasoning on top works wonders. For a crunchy touch, consider adding a handful of homemade croutons or crispy bacon bits.

Side Dishes

Soup this hearty pairs best with something to help scoop up every last spoonful. Think thick slices of crusty French bread, warm cornbread, or buttery garlic toast. For something lighter, a simple green salad with a citrusy vinaigrette balances the spicy and creamy notes of the soup beautifully.

Creative Ways to Present

Elevate your next meal by serving Cajun Potato Soup in individual bread bowls or mugs for a cozy, rustic touch. You can also ladle it over a bed of cooked white or brown rice for an extra-filling meal. Hosting a party? Set up a soup bar with toppings like shredded cheese, sour cream, chives, and hot sauce so everyone can customize their own bowl.

Make Ahead and Storage

Storing Leftovers

Cool any remaining Cajun Potato Soup to room temperature, then store it in an airtight container in the refrigerator for up to 4 days. The flavors will meld together and get even better overnight, making leftovers a true treat. Just give it a gentle stir before reheating, as the soup will thicken as it sits.

Freezing

You can absolutely freeze Cajun Potato Soup for easy meals later! Let the soup cool completely before transferring it to freezer-safe containers, leaving a little space at the top for expansion. The texture of potatoes might change a bit after thawing, but the soup will still be full of flavor. Enjoy within 2 months for best results.

Reheating

Reheat leftovers gently on the stovetop over low heat, stirring often to keep the soup creamy. If the soup thickened in the fridge, add a splash of chicken broth or milk to loosen it up. You can also microwave smaller portions, stopping to stir every minute for even warming.

FAQs

How spicy is Cajun Potato Soup?

It has a gentle kick from the Cajun seasoning and cayenne, but it’s easy to adjust! For milder soup, reduce or skip the cayenne. If you love heat, bump up the Cajun seasoning or add hot sauce to serve.

Can I use another type of sausage?

Absolutely! While andouille is traditional and gives the soup its authentic flavor, smoked kielbasa or chorizo work nicely as alternatives if you can’t find andouille.

What’s the best potato to use?

Russets are ideal because they break down just enough to thicken the soup while still offering chunks for texture. Yukon Golds can also work for a more buttery bite.

Can I make Cajun Potato Soup vegetarian?

Definitely! Simply leave out the sausage and swap chicken broth for vegetable broth. For added flavor, try smoked paprika and a handful of sautéed mushrooms to mimic that smoky depth.

How do I thicken or thin out the soup?

For a thicker Cajun Potato Soup, mash some of the potatoes in the pot or simmer it uncovered a bit longer. To thin, just add more broth or a splash of milk until it’s the consistency you like.
