This robust Cajun potato soup combines Louisiana's bold tastes with the warmth of traditional potato soup. Spicy andouille sausage, soft potatoes, and a thick, velvety base come together in a warming dish that's great for everyday meals or weekend get-togethers.
I whipped up this soup one cool fall night when I wanted something with some heat. After trying the first bite, my family instantly claimed it as their new favorite, and now we turn to it whenever it's cold outside or we're longing for a taste of Southern comfort.
Ingredients
- Andouille sausage: This classic Cajun pork sausage brings authentic taste and spiciness. Try to find one with visible spice flecks and good firmness.
- Cajun seasoning: The key flavor element in our soup. Good Cajun blends should have several layers of herbs and spices.
- Russet potatoes: They naturally thicken the soup while keeping their structure. Go for solid potatoes with no greenish areas.
- Heavy whipping cream: Gives the soup its smooth, rich texture. Don't skimp on fat content for the best outcome.
- Mild cheddar cheese: Adds creaminess and flavor without fighting the Cajun spices. Grate it yourself for better melting.
- Fresh vegetables: Onions, celery, and bell peppers form the essential Cajun cooking base that builds the soup's flavor foundation.
Step-by-Step Instructions
- Brown the Sausage:
- Warm vegetable oil in a big pot over medium heat until it shimmers. Toss in the sliced andouille and cook 3-4 minutes, turning now and then until you see a nice brown crust form. This step really matters since it pulls out the smoky flavors that'll season the whole soup. Take the sausage out but keep all those tasty bits in the pot.
- Sauté the Holy Trinity:
- Throw in your chopped onion, celery, and red bell pepper right into the pot with those sausage drippings. Cook them over medium heat for 5-8 minutes, stirring often until everything gets soft and the onions turn clear. Add your minced garlic in the last minute, but watch it closely so it doesn't burn and make things bitter. You want soft veggies, not browned ones.
- Build the Soup Base:
- Scatter the Cajun seasoning, salt, black pepper, paprika, and cayenne over your veggies, stirring to coat everything. This quick spice toasting brings out their flavors. Pour in your chicken broth and add the potato cubes, giving everything a good stir. Turn the heat down to a gentle bubble and let it cook uncovered for 20-25 minutes, until you can easily stick a fork in the potatoes.
- Create the Creamy Finish:
- Put the browned sausage back in the pot, pour in the heavy cream and sprinkle in your shredded cheddar. Let it simmer gently for another 5 minutes, stirring now and then to help the cheese melt smoothly. The soup will thicken up a bit as it cooks. Give it a taste and add more seasoning if needed before serving with fresh parsley on top.

The andouille sausage really makes this dish special. I first tried it during a trip to New Orleans many years back, and I've been cooking with it ever since. The way it fills the broth with smoky, spicy notes creates a richness you can't get from anything else. My family always says they can tell what kind of day I've had by how much cayenne ends up in this soup!
Spice Level Management
You've got total control over how hot this Cajun potato soup turns out. Want something milder that everyone will enjoy? Just cut back on the cayenne and pick a gentler Cajun seasoning mix. If you love heat, add more of both and maybe grab a spicier andouille sausage. Don't forget that the cream and cheese help cool things down, so you'll still get a balanced taste even with extra spice. That's what's so great about this soup – you can adjust the heat while keeping all the authentic Cajun flavors.
Make-Ahead Options
This soup gets even better over time, so it's perfect for planning ahead. Make it a day early and keep it in the fridge to let all those flavors blend overnight. When you're ready to eat, warm it up slowly over medium-low heat, stirring every now and then so it doesn't burn. If it's gotten too thick while sitting, just splash in a bit more chicken broth or cream to thin it out. Having this waiting for you after a long day makes the cooking time totally worth it.

Serving Suggestions
Make a full meal out of this soup by pairing it with hot, crusty French bread for dipping. The mix of crunchy bread outside and creamy soup creates an amazing texture combo that makes the dish even better. Want something lighter on the side? A simple green salad with vinaigrette gives a fresh contrast to the rich soup. If you're having friends over, try serving the soup in hollowed-out bread bowls for a fancy look that doesn't take much extra work. The bread soaks up all that tasty broth while adding another element to your meal.
