Instructions
Dice the onion, celery, and bell pepper into uniform 1/4-inch pieces. Mince the garlic, peel and cube the potatoes into 3/4-inch pieces, and slice the Andouille sausage into 1/4-inch rounds.
Heat olive oil in a large Dutch oven over medium heat. Add the onion and cook 3–4 minutes, then add celery and bell pepper and cook 5 more minutes. Stir in garlic and cook 30 seconds until fragrant.
Push the vegetables to the side and add the sausage slices. Cook 3–4 minutes until browned, then mix together with the vegetables.
Stir in the cubed potatoes, then sprinkle in the Cajun seasoning, smoked paprika, and cayenne. Cook 2 minutes, stirring constantly to toast the spices and coat the potatoes.
Pour in the chicken broth, ensuring all potatoes are submerged, then add the bay leaf. Bring to a boil, then reduce to a gentle simmer, cover partially, and cook 20–25 minutes until potatoes are fork-tender.
Remove and discard the bay leaf. Use a potato masher to mash about half the potatoes directly in the pot to create a naturally thick, creamy texture while leaving some chunks.
Reduce heat to low and slowly stir in the heavy cream. Heat through for 3–4 minutes without boiling, then taste and adjust seasoning with salt and black pepper.
Ladle the hot soup into bowls and garnish with freshly chopped parsley and sliced green onions. Serve immediately.
Notes
Best potatoes: Yukon Gold potatoes are ideal — they break down slightly for natural creaminess while still holding some shape. Russets work but become mushier.
Don't skip browning the sausage: Browning the Andouille develops deep savory flavor and the rendered fat adds richness to the whole soup.
Toast your spices: Cooking the Cajun seasoning with the vegetables before adding liquid activates the spices and removes any raw, powdery taste.
Control the heat: Start with less cayenne than you think you need — you can always add more at the end, but you can't take it away.
Add cream off heat: Reduce to low before adding cream to prevent it from curdling or breaking.
Slow cooker option: Brown the sausage and sauté vegetables first, then transfer to a slow cooker with remaining ingredients. Cook on low 6–8 hours or high 3–4 hours; stir in cream during the last 30 minutes.
Storage: Refrigerate in an airtight container for up to 4 days. Freeze in portion-sized containers for up to 3 months.
Reheating: The soup thickens when cold — add a splash of broth or cream when reheating on the stovetop over medium-low heat.
Sausage substitutes: Kielbasa, smoked turkey sausage, or chorizo all work well. For vegetarian, use plant-based sausage or extra vegetables with vegetable broth.
Too thin? Mash more potatoes, or stir in a slurry of 2 tbsp cornstarch mixed with 2 tbsp cold water and simmer a few minutes until thickened.
