Ingredients

Scale
  • 1 tablespoon vegetable oil
  • 1 pound Andouille sausage, sliced
  • 1 large onion, diced
  • 1/2 cup diced celery
  • 2 cloves garlic, minced
  • 2 tablespoons Cajun seasoning blend (or more to taste)
  • 1/4 teaspoon cayenne pepper (optional, for extra heat)
  • 4 cups chicken broth
  • 2 pounds Russet potatoes, peeled and diced
  • 1 teaspoon dried thyme
  • 1 bay leaf
  • 1/2 cup all-purpose flour
  • 1 cup whole milk
  • 1 cup heavy cream
  • 1 cup shredded sharp cheddar cheese
  • Salt and black pepper to taste
  • Chopped green onions, for garnish

Instructions

  1. Heat the vegetable oil in a large Dutch oven or stockpot over medium-high heat. Add the sliced Andouille sausage and cook until browned, about 5 to 7 minutes. Remove the sausage with a slotted spoon and set aside, leaving about 1 tablespoon of drippings in the pot.
  2. Add the diced onion and celery to the pot. Cook until softened, about 5 minutes. Add the minced garlic, Cajun seasoning, and cayenne pepper (if using). Cook for 1 minute until fragrant.
  3. Whisk the flour into the vegetables and drippings, cooking for 1 minute to create a roux base.
  4. Slowly whisk in the chicken broth until smooth. Add the diced potatoes, dried thyme, and bay leaf. Bring the mixture to a boil, then reduce heat to low, cover, and simmer for 15 to 20 minutes, or until the potatoes are tender.
  5. Remove and discard the bay leaf. Stir in the whole milk and heavy cream. Heat through gently, but do not allow the soup to boil after adding the dairy.
  6. Stir in the cooked Andouille sausage and the shredded cheddar cheese until the cheese melts and the soup thickens slightly.
  7. Taste the soup and adjust seasoning with salt and pepper as needed.
  8. Serve hot, garnished with chopped green onions.

Notes

  • For a thicker soup, mash about 1 cup of the potatoes against the side of the pot before adding the cream.
  • If you prefer a milder flavor, use half the amount of Cajun seasoning or use a mild blend.
  • You can substitute smoked sausage for Andouille if you cannot find it.
