What Makes Andouille Sausage Special?
Andouille sausage is a key ingredient in authentic Cajun cuisine. It’s:
- Smoked
- Coarsely ground

Its deep smoky flavor adds richness that elevates this creamy potato soup beyond a basic comfort dish.
If you can’t find andouille, smoked sausage or kielbasa can work—but you’ll miss some of that classic Cajun depth.
How to Make Creamy Cajun Potato Soup with Andouille Sausage
This recipe is simple and perfect for beginner cooks. Follow these step-by-step instructions for the best results.
Step 1: Brown the Andouille Sausage
Heat a large Dutch oven or heavy-bottomed pot over medium heat.
Add:
- 1 tablespoon olive oil
- Sliced andouille sausage
Cook for 4–5 minutes until the sausage develops a golden-brown crust. Browning enhances flavor through caramelization.
Remove sausage and set aside.
Step 2: Sauté the Aromatics
In the same pot, add:
- 2 tablespoons butter
- Onions
- Bell peppers
- Celery
Cook for about 5–7 minutes until softened.
Add minced garlic and cook for another 30 seconds until fragrant.
This trio of onion, bell pepper, and celery is known as the “Holy Trinity” of Cajun cooking and forms the flavor base of the soup.
Step 3: Add Potatoes and Seasoning
Stir in:
- Diced potatoes
- 2 tablespoons Cajun seasoning
Cook for 1–2 minutes to toast the spices slightly.
Toasting helps intensify the flavors.
Step 4: Add Broth and Simmer
Pour in 4 cups chicken broth.
Bring to a gentle boil, then reduce heat and simmer for 15–20 minutes until the potatoes are fork-tender.
Tip: Yukon Gold potatoes create a naturally creamy texture without needing flour.
Step 5: Add Sausage and Cream
Return the browned sausage to the pot.
Stir in:
- 1 cup heavy cream (or half and half)
Simmer for 5 more minutes to allow flavors to blend.
Taste and adjust salt and pepper as needed.
Step 6: Garnish and Serve
Top with:
- Sliced green onions or chives
- Shredded cheese
- Bacon bits
- Sour cream
- Fresh parsley
Serve hot with crusty bread or cornbread.
Tips for the Best Cajun Potato Soup
Want restaurant-quality results? Follow these expert tips:
1. Don’t Overcook the Potatoes
They should be tender but not mushy. Overcooking can turn the soup gluey.
2. Adjust Spice Level
Cajun seasoning blends vary. If yours is spicy:
- Start with 1 tablespoon
- Add more gradually
3. Mash for Extra Creaminess
For thicker soup:
- Lightly mash some potatoes in the pot
- Or blend 1–2 cups and stir back in
4. Use Fresh Herbs for Brightness
Fresh parsley or chives balance the richness beautifully.
How to Make It Even Creamier
If you want ultra-luxurious texture:
- Add ½ cup cream cheese
- Stir in shredded cheddar
- Blend part of the soup
- Use full heavy cream instead of half and half
Each method increases richness while keeping that bold Cajun flavor intact.
Make It Healthier (Without Losing Flavor)
Want a lighter version?
- Use half and half instead of heavy cream
- Reduce sausage to 8 oz
- Add extra vegetables
- Use turkey andouille
The soup remains flavorful and satisfying.
Storage and Reheating Tips
Refrigerator
Store in an airtight container for up to 4 days.
Freezer
Cream-based soups can separate when frozen, but you can:
- Freeze before adding cream
- Add cream after reheating
Freeze up to 2 months.
Reheating
Reheat gently over low heat.
Add a splash of broth or milk if it thickens too much.
Perfect Side Dishes to Serve With Cajun Potato Soup
