Cajun Potato Soup is the kind of meal that wakes you up from the inside out. Smoky andouille sausage, hearty potatoes, veggies, and a punchy blend of Cajun spices create a creamy soup with a pleasant kick. When my family needs something warming but a little exciting, this is what lands on our dinner table.
I first threw this soup together on a chilly night when I wanted that classic potato comfort with more personality. Now it is our go-to when we crave something soothing but not subtle.
Ingredients
- Andouille sausage: sliced for bold smoky flavor choose one with a good snap
- Vegetable oil: to brown the sausage and build up those tasty bits on the pot
- Large onion: diced to quietly mellow out the heat
- Celery: for savory balance and aromatics make sure it is crisp and bright
- Red bell pepper: adds color and underlying sweetness go for a deep red one
- Fresh garlic: lifts all the other flavors whole heads feel firm and tight
- Cajun seasoning: brings the heat and complex spice try for a blend without additives
- Kosher salt and black pepper: calibrate the flavors
- Paprika and cayenne pepper: deepen the warmth and add a touch of earthy spice
- Chicken broth: as the rich cooking liquid use a low-sodium or homemade if you can
- Russet potatoes: peeled and cubed for heartiness select dry ones that feel heavy
- Heavy cream: for that luscious creamy finish use the freshest possible
- Mild cheddar cheese: shredded to melt smoothly for a velvety bite
- Parsley: chopped for a green pop and a fresh finish
Step-by-Step Instructions
- Brown the Sausage:
- Add vegetable oil to a large sturdy pot and let it heat over medium. Drop in your sausage rounds. Sauté for three to four minutes stirring now and then until caramelized edges appear and the aroma builds. Transfer sausage out with a slotted spoon but do not clean the pot as all that flavor stays behind.
- Sauté the Vegetables:
- In the same pot tip in diced onion celery and bell pepper. Cook over medium so the vegetables soften and start to turn translucent about five to eight minutes. Stir as needed so nothing sticks. Add minced garlic and cook another minute until fragrant without letting it brown.
- Build the Soup Base:
- Scatter the Cajun seasoning kosher salt black pepper paprika and cayenne over the veggies. Pour in the chicken broth and add the potatoes. Stir well to loosen any stuck bits from the bottom which deepens the flavor. Lower the heat and let it gently simmer for twenty to twenty five minutes or until potatoes yield easily to a fork.
- Finish and Serve:
- Tip the browned sausage back in followed by the heavy cream and shredded cheddar. Let the soup gently bubble for another five minutes until everything is hot and the cheese is thoroughly melted into the broth. Taste for seasoning adjusting if needed. Ladle into bowls and top with a handful of chopped parsley. Serve warm right away.

I am especially fond of using high-quality andouille sausage here. In fact my cousin once brought back authentic Cochon de Lait sausage from Louisiana and the soup was unforgettable. Now we make it together every time we get our hands on something special.
Storage Tips
Let the soup cool fully before moving it to airtight containers. It stays delicious in the fridge for three days. If you want to freeze it skip adding the cream and cheese until reheating as dairy can sometimes split in the freezer. Warm up gently on the stovetop stirring often.
Ingredient Substitutions
If you cannot find andouille try kielbasa or chorizo for different twists. Sweet potatoes work well in place of russets and give the soup a pleasant earthiness. Any melty cheese will do if mild cheddar is not handy—Monterey Jack or Swiss also blend in easily.
Serving Suggestions
For a bigger meal pair with a crisp green salad or a slab of cornbread. A few hot sauce dashes will brighten each bowl. Leftovers are great for lunch topped with more cheddar or a swirl of Greek yogurt.
Cultural Context
This soup draws its flavor from classic Cajun traditions blending French influences with Southern comfort food roots. The combination of potatoes veggies sausage and warming spices is a staple in many Louisiana kitchens where recipes are shared and shaped by a love of lively food.
