Ingredients

Meat

  • 1 ring (13.5 ounces) andouille sausage, sliced into ¼-inch rounds

Vegetables

  • 1 large onion, diced (about 1 cup)
  • ½ cup diced celery (about 1 rib)
  • ½ red bell pepper, seeded and diced
  • 2 teaspoons garlic, minced
  • 4 large russet potatoes, peeled and cubed
  • Parsley, chopped for garnish

Liquids & Dairy

  • 4 cups (960 g) chicken broth
  • ½ cup (119 g) heavy whipping cream
  • 1 cup (113 g) mild cheddar cheese, shredded

Seasonings

  • 1 tablespoon vegetable oil
  • 2 teaspoons Cajun seasoning
  • ½ teaspoon kosher salt
  • ½ teaspoon black pepper
  • ½ teaspoon paprika
  • ¼ teaspoon cayenne pepper

Instructions

  1. Prepare the sausage: Heat oil in a large pot over medium heat. Add the sliced andouille sausage and cook, stirring occasionally, until browned, about 3-4 minutes. Remove the sausage from the pot and set it aside on a plate for later use.
  2. Sauté the vegetables: In the same pot, add the diced onion, celery, and red bell pepper. Cook over medium heat until the vegetables are softened, approximately 5-8 minutes. Add the minced garlic and sauté for an additional 1 minute to release its aroma.
  3. Add the seasonings and potatoes: Stir in the Cajun seasoning, kosher salt, black pepper, paprika, and cayenne pepper. Pour in the chicken broth and add the peeled and cubed potatoes. Reduce the heat and let the soup simmer gently for 20-25 minutes, or until the potatoes are tender when pierced with a fork.
  4. Combine sausage, cream, and cheese: Return the browned sausage to the pot. Stir in the heavy whipping cream and shredded mild cheddar cheese. Continue simmering the soup for an additional 5 minutes until the cheese has melted and the soup is heated through.
  5. Serve and garnish: Ladle the soup into bowls and garnish with freshly chopped parsley. Serve warm for a comforting and flavorful meal.

Notes

  • For a thicker soup, mash some of the potatoes into the broth before adding the sausage back in.
  • Adjust the cayenne pepper to your preferred spice level.
  • You can substitute andouille sausage with smoked sausage if unavailable.
  • This soup can be made a day ahead; flavors deepen after resting.
  • Use low-sodium chicken broth to reduce the saltiness if desired.
