Ingredients
  

For the soup base

  • 1 lb andouille sausage, sliced or crumbled Substitute smoked kielbasa if unavailable.
  • 2-3 medium potatoes, peeled and diced Yukon Gold for creaminess or russet for easier mashing.
  • 1 medium onion, diced
  • 1 green bell pepper diced
  • 2 stalks celery, diced
  • 2-3 cloves garlic, minced
  • 1-2 tbsp Cajun seasoning Adjust to taste.
  • 4-6 cups water or broth Chicken or vegetable; enough to cover the ingredients.
  • 1 cup heavy cream For richness.
  • 1-1.5 cups shredded sharp cheddar cheese Stir in off heat to prevent clumping.
  • to taste Salt and black pepper

For garnishing (optional)

  • to taste sliced scallions
  • to taste chopped parsley
  • to taste extra cheese
  • to taste hot sauce

Instructions
 

Cooking the Soup

  • Heat a large heavy-bottomed pot over medium heat. Add the sliced andouille and cook until browned and slightly crisp, about 5–7 minutes. Transfer half the sausage to a bowl for garnish if you like; leave the rendered fat in the pot.
  • Add diced onion, bell pepper, and celery to the pot. Sauté until softened, about 4–5 minutes. Stir in minced garlic and Cajun seasoning; cook for 30–60 seconds until fragrant.
  • Add diced potatoes and the remaining browned sausage. Pour in enough water or broth to just cover the ingredients. Turn heat up to bring the pot to a boil.
  • Once boiling, reduce heat to a simmer. Cover partially and simmer until potatoes are tender when pierced with a fork, about 12–18 minutes depending on dice size.
  • Reduce heat to low. Stir in the heavy cream, then add the shredded cheddar a handful at a time, stirring until melted and smooth.
  • If the soup is too thin, mash some potatoes against the pot sides or simmer uncovered a few minutes to reduce.
  • Taste and season with salt and freshly ground black pepper. Serve hot with reserved sausage and garnishes.

Notes

For a lighter finish, use half-and-half; you may need a thickener. Vegetarian options available by replacing andouille with smoked tempeh or plant-based sausage and using vegetable stock. Follow food safety best practices for storage and reheating.
