Pin it This robust soup brings together tender russet potatoes, aromatic vegetables, and smoky Andouille sausage in a velvety cream-based broth. The signature Cajun seasoning blend—featuring smoked paprika, garlic, and cayenne—delivers that distinctive Southern warmth and depth. Perfect for cold weather or when you crave satisfying comfort food, this one-pot meal comes together in just 55 minutes and serves six hungry people.
The technique involves building flavor through sausage browning, vegetable aromatics, and a simple flour-thickened base before simmering potatoes until perfectly tender. Partial mashing creates that ideal creamy consistency while keeping satisfying potato chunks throughout.
The first time I made this soup, it was a rainy Tuesday and I had a bag of potatoes that needed using. I threw in some Andouille sausage I had in the freezer and half a jar of Cajun seasoning my brother brought back from New Orleans. My roommate walked in from work, stopped dead in her tracks, and asked what smelled like a proper Southern kitchen.
Last winter I made a triple batch for a sick friend and her family. She texted me later saying her kids, who usually complain about soup, had thirds and asked when I was coming over to cook again.
Ingredients
- Russet potatoes: These break down beautifully and create that velvety thickness without needing much cream
- Andouille sausage: The smoky heat is the backbone of this soup, and browning it first builds flavor in the pot
- Heavy cream: Just one cup makes it luxurious without overwhelming the spices
- Cajun seasoning: Homemade is best but Tony Chacheres works perfectly fine here
- Flour: Helps create that silky restaurant style texture that makes people think you simmered this all day
Instructions
- Get your sizzling foundation started:
- Heat olive oil and butter in a large soup pot over medium heat until the butter foams slightly, then add your sausage slices and cook until they develop a gorgeous brown crust, about 4 to 5 minutes. Remove sausage and set aside, leaving all those flavorful brown bits in the bottom of your pot.
- Build your flavor base:
- Add onion, celery, and bell pepper to the pot and saute for 4 to 5 minutes until they soften and start to smell amazing. Stir in garlic and cook for just 1 minute until fragrant but not browned.
- Create the roux:
- Sprinkle flour over vegetables, stir constantly, and cook for 1 to 2 minutes to remove the raw flour taste. Gradually whisk in chicken broth, scraping up all those browned bits from the bottom of the pot.
- Simmer the soup:
- Add diced potatoes, Cajun seasoning, smoked paprika, cayenne if you like heat, salt, and black pepper. Bring to a boil then reduce heat to a simmer, cover, and cook for 15 to 18 minutes until potatoes are completely tender.
- Make it creamy and finish:
- Use a potato masher or immersion blender to partially puree the soup for a creamy texture while leaving some chunks for texture. Stir in the browned sausage and heavy cream, simmer uncovered for 5 more minutes, then taste and adjust seasoning.
- Serve it up:
- Ladle into bowls and garnish with green onions and parsley. I like to let people add extra hot sauce at the table so everyone can control their own heat level.
Pin it This soup has become my go to for bringing to new parents or anyone who needs a meal that feels like a hug. Something about the combination of creamy potatoes and spicy sausage just makes everything better.
Making It Your Own
I have made this with smoked turkey instead of sausage and it works beautifully. You can also add corn kernels or shredded rotisserie chicken in the last five minutes of simmering if you want to stretch it further.
What To Serve With It
Cornbread is the obvious choice here but any crusty bread will do. I also love serving this with a simple green salad dressed with vinegar to cut through the richness.
Make Ahead And Storage
This soup actually tastes better the next day so do not hesitate to make it in the morning or the night before. It freezes well for up to three months, just thaw and reheat gently with a splash of cream to bring it back to life.
- Cool completely before storing to prevent bacteria growth
- Reheat slowly over medium low heat to prevent separating
- The soup will thicken in the fridge so add broth when reheating
Pin it There is nothing quite like sitting down with a steaming bowl of this soup and watching the rain outside. Hope it becomes as much of a comfort in your kitchen as it has in mine.
Recipe Questions & Answers
- → Can I make this soup spicy?
-
Absolutely. Adjust the heat level by increasing the cayenne pepper up to 1 teaspoon, or add extra Cajun seasoning to taste. For milder flavor, reduce or omit the cayenne entirely while keeping the smoky paprika for depth.
- → What's the best way to achieve the creamy texture?
-
Use a potato masher to partially break down about half the potatoes once they're tender. This releases natural starches for thickness while maintaining hearty chunks. An immersion blender works too—just pulse briefly to avoid over-pureeing.
- → Can I prepare this soup in advance?
-
Yes. Make it up to 2 days ahead and refrigerate. The flavors actually improve overnight. Reheat gently over medium-low heat, adding a splash of broth if needed. Hold off on garnishes until serving.
- → What substitutes work for Andouille sausage?
-
Smoked kielbasa, chorizo, or any smoked sausage will work well. For a vegetarian version, use extra vegetables and add smoked paprika or liquid smoke to maintain that savory depth.
- → Is this soup freezer-friendly?
-
Yes, freeze for up to 3 months in airtight containers. Cream-based soups can separate slightly when thawed—simmer gently while stirring to recombine. Add fresh garnishes after reheating.
- → What sides pair well with this soup?
-
Crusty French bread, homemade cornbread, or buttery biscuits soak up the broth beautifully. A simple green salad with vinaigrette provides a fresh contrast to the rich, creamy soup.
