This Creamy Cajun Potato Soup is the ultimate comfort food for days when you want something rich, spicy, and soul-warming. Fork-tender Yukon Gold potatoes and smoky andouille sausage mingle in a silky broth full of Cajun seasoning. Inspired by classic Southern flavors, every spoonful comes alive with zesty heat and velvety texture. This is my go-to soup when I want to impress friends or hunker down with a big bowl on a chilly night.
My family devours this every time it is on the table. I first made it on a surprisingly cold spring afternoon and now it is on our regular rotation. The creamy broth and kick of heat never get old.
Ingredients
- Yukon Gold Potatoes: provide creaminess and hold their shape in the soup Use firm potatoes with smooth skins for best results
- Butter and Olive Oil: add richness and prevent veggies from sticking to the pot Go for high quality unsalted butter for better flavor
- Yellow Onion Celery Green Bell Pepper: these fresh veggies form the flavor backbone of almost any Cajun recipe Use crisp produce and chop in even pieces
- Garlic: fresh cloves add punchy aroma and complexity Pick plump unblemished bulbs
- Andouille Sausage: delivers a signature smoky spicy bite Look for traditional Cajun andouille with a deep red color
- Chicken or Vegetable Broth: is the flavor base Choose low sodium for better salt control
- Heavy Cream: creates a silky mouthfeel and rounds out the seasoning Use fresh cream not half and half
- Cajun Seasoning: brings the unmistakable Louisiana kick to the party Homemade or a trusted store-bought blend both work
- Shredded Cheddar Cheese for garnish: adds depth and a sharp creamy contrast to the spicy broth Choose a block to shred yourself for best melting
- Sliced Green Onions for garnish: provide a fresh mild onion pop Add them just before serving
Step-by-Step Instructions
- Prep the Potatoes:
- Microwave peeled potato chunks in a bowl with a few spoonfuls of water loosely covered Stir them a couple times during cooking until just fork tender about five to eight minutes Drain and set aside
- Sauté the Trinity:
- In a large pot melt butter with olive oil over medium heat Add chopped onion celery and green bell pepper Cook for four to five minutes until veggies are soft and onions look translucent Stir in minced garlic and sauté just one minute until fragrant
- Brown the Sausage:
- Add sliced andouille sausage directly to the pot Stir and cook around four to five minutes until it takes on a deep golden color and releases its smoky aroma
- Simmer with Broth and Potatoes:
- Pour in chicken or vegetable broth Then add your microwaved potatoes Bring everything to a gentle simmer Let the pot bubble for twelve to fifteen minutes until the potatoes are very tender but not falling apart
- Make it Creamy:
- Set the heat to low Stir in heavy cream plus your Cajun seasoning Taste and adjust until the flavors are bold Heat just enough to warm through and avoid boiling to keep that creamy texture
- Serve and Garnish:
- Ladle the hot soup into bowls Top each serving with generous shredded cheddar and fresh green onions Serve while steaming

The smoky andouille sausage is always my favorite part It reminds me of Sunday dinners growing up when there was always something spicy simmering in the kitchen My kids now race to get the bowl with the most sausage
Storage Tips
Cool your soup fully before transferring to airtight containers in the fridge Store garnishes like cheese and green onions separately so they stay fresh Soups with cream are best eaten within three days Refrigerate leftovers promptly or freeze without the cream for up to three months To reheat gently warm on the stovetop stirring often for even heating Add a splash more broth if needed and stir the cream in just before serving
Ingredient Substitutions
Trade out andouille sausage for kielbasa or mild smoked sausage if you want less heat Plant-based sausage makes this vegetarian For a thicker texture mash some potatoes with a fork or pureé part of the soup Do not be shy to toss in diced carrots corn or even cooked shrimp especially for a seafood twist
Serving Suggestions
Garnish with crumbled bacon crispy onions or even a dollop of sour cream if you want extra richness Fresh parsley or a bit of hot sauce works great too Pair with warm crusty bread or buttery cornbread when you need a little extra comfort

Cajun Roots
This soup draws on the classic flavors of Cajun country with its trinity of onion celery and bell pepper plus the signature deep red sausage Originally from Louisiana Cajun cuisine is all about big flavors and resourceful home cooking This one-pot wonder honors those traditions but fits easily into a weeknight menu
Commonly Asked Questions

Yukon Gold potatoes are ideal, holding their shape while providing a creamy texture. Russets can be used for a thicker texture, or red potatoes for less starch.

Yes, smoked sausage, kielbasa, or chicken sausage can replace andouille for a milder flavor. Even plant-based sausage works well.
- → How do I make it thicker?
Use an immersion blender to puree some soup before adding the cream, or gently mash some potatoes for a chunkier finish.

The 'Holy Trinity'—onion, celery, and bell pepper—forms the aromatic base, delivering signature Cajun depth and sweetness.
- → Are there other topping options?
Add crispy bacon bits, fried onions, fresh parsley, or extra cheddar to personalize each bowl. Corn or shrimp add more Southern flair.
