Ingredients
  

  • 2 tablespoons extra-virgin olive oil for sautéing
  • 13- ounce spicy smoked sausage sliced into discs (such as andouille)
  • 1 small yellow onion chopped (about ¾ cup)
  • 1 medium red bell pepper seeded and chopped
  • 2 ribs celery chopped
  • 3 cloves garlic minced (fresh for flavor)
  • 3 teaspoons homemade or store-bought Cajun seasoning divided use
  • 2 tablespoons unsalted butter for roux
  • 3 tablespoons all-purpose flour for roux
  • 4 cups low-sodium chicken broth
  • ½ cup half and half for creaminess
  • 4 large russet potatoes peeled and cubed (about 3–4 cups)
  • 1 cup sharp cheddar cheese shredded (for finishing)
  • Salt and cracked black pepper to taste (season gradually)
  • Fresh chopped parsley for garnish

Method
 

  1. Heat olive oil in a 5-quart Dutch oven over medium heat. Add the sausage slices and cook until browned, then transfer to a plate and set aside.
  2. Add chopped onion, bell pepper, and celery to the same pot and cook 2–3 minutes until softened. Stir in minced garlic and cook another minute until fragrant.
  3. Add butter and flour to the pot, stirring continuously to form a roux. Cook 2–3 minutes to eliminate raw flour taste.
  4. Gradually whisk in chicken broth and half and half, ensuring the roux incorporates smoothly.
  5. Add cubed potatoes and 2 teaspoons of Cajun seasoning. Reduce heat to medium-low and simmer 20–25 minutes until potatoes are tender, stirring occasionally.
  6. Stir the cooked sausage and shredded cheddar cheese into the soup until the cheese melts. Mix well and heat through.
  7. Season with remaining Cajun seasoning, salt, and black pepper to taste. Remove from heat and ladle into bowls.
  8. Garnish with fresh parsley before serving.
