| Smoked Sausage (or Andouille) | 8 oz | Adds rich Cajun depth |
| Butter | 2 tbsp | For sautéing vegetables |
| Onion | 1 medium | Finely chopped |
| Celery | 2 stalks | Diced |
| Bell Pepper | 1 | Red or green |
| Garlic | 3 cloves | Minced |
| Cajun Seasoning | 2 tbsp | Adjust to preference |

🍳 Step-by-Step Instructions
1. Sauté the Base
In a large soup pot or Dutch oven, melt butter over medium heat. Add diced onion, celery, and bell pepper. Cook until the vegetables are soft and aromatic — about 5 minutes. Stir in minced garlic and cook for 1 more minute.
2. Add the Sausage
Add the sliced sausage to the pot and cook until lightly browned. This step releases flavorful oils that become the backbone of the soup.
3. Season & Simmer
Sprinkle in the Cajun seasoning and smoked paprika. Stir for 30 seconds to bloom the spices — this releases their essential oils and deepens the flavor.
Add diced potatoes and chicken broth. Bring to a boil, then reduce to a simmer. Cook uncovered for about 15–20 minutes, until the potatoes are tender.
4. Create the Creamy Texture
Once the potatoes are soft, use a potato masher or immersion blender to mash some of them directly in the pot. This naturally thickens the soup without adding extra starch.
5. Finish with Cream
Pour in heavy cream and stir well. Let it simmer for another 3–4 minutes. Taste and adjust salt and pepper as needed.
6. Serve & Garnish
Ladle the soup into bowls and top with shredded cheddar, sliced green onions, or a dash of extra Cajun seasoning.
🧑🍳 Expert Tips for the Perfect Cajun Potato Soup
- Bloom your spices: Always cook Cajun seasoning in butter or oil before adding liquid — it brings out the aroma and depth.
- Balance the heat: For a milder soup, reduce the Cajun seasoning or add a splash of cream.
- Texture trick: Mash just half the potatoes for the ideal creamy-chunky balance.
- Layer the flavor: Add a splash of hot sauce or Worcestershire for an umami lift.
- Make it ahead: The flavors deepen overnight — this soup tastes even better the next day.
