Cajun Potato Soup is a bold, creamy, and comforting dish made with smoky sausage, hearty potatoes, and classic Cajun seasonings. Perfect for chilly nights or whenever you crave something spicy and satisfying.

Ingredients

  • Russet or Yukon potatoes – creamy base and hearty texture
  • Cajun sausage (andouille) – smoky, spicy depth and heartiness
  • Onion, bell pepper, celery – Cajun ‘Holy Trinity’ for flavor foundation
  • Garlic – boosts aromatic depth
  • Chicken broth – builds the soup’s savory liquid base
  • Heavy cream – delivers silky, rich texture
  • Cajun seasoning – adds signature heat and bold flavor
  • Butter and olive oil – sautéeing base for vegetables
  • Salt and black pepper – balances and enhances all other flavors
  • Green onions – fresh garnish and brightness
  • Cheddar cheese (optional) – adds extra richness and flavor

Instructions

  1. Heat olive oil and butter in a large pot. Sauté onion, bell pepper, and celery until soft.
  2. Add garlic and sausage; cook until sausage is browned.
  3. Stir in diced potatoes and Cajun seasoning to coat evenly.
  4. Pour in chicken broth, bring to boil, then simmer until potatoes are tender.
  5. Mash some potatoes in the pot to thicken the soup naturally.
  6. Stir in heavy cream and simmer for a few more minutes.
  7. Add cheddar cheese (optional), then season with salt and pepper to taste.
  8. Turn off heat and let soup rest for 10 minutes to thicken and meld flavors.
  9. Garnish with green onions and serve.

Notes

  • Use a mix of mashed and whole potatoes for ideal consistency.
  • Don’t rush the sautéing step—develop deeper flavor by cooking aromatics slowly.
  • Adjust Cajun seasoning and pepper flakes based on heat preference.
  • Make vegetarian by using plant-based sausage and vegetable broth.
  • For added texture, stir in corn or black beans near the end.
