Instructions
-
Brown the sausage
In a large Dutch oven, cook the andouille sausage over medium heat for 3–5 minutes until lightly browned. Remove and set aside. -
Build your flavor base
In the same pot, melt butter and add olive oil. Stir in garlic and red pepper flakes, cooking for 1 minute until fragrant. -
Sauté the vegetables
Add onion, red pepper, and celery. Cook for 5–7 minutes until softened and aromatic. -
Add broth and seasonings
Pour in chicken broth, then add Cajun seasoning, smoked paprika, and salt. Stir and bring to a gentle boil. -
Add potatoes
Reduce heat and simmer uncovered for 15–18 minutes until potatoes are fork-tender. -
Make it creamy
Lower the heat, then stir in heavy cream, cheddar cheese, and Parmesan until melted and smooth. -
Finish and serve
Return the sausage to the pot, add parsley, and simmer for 2–3 minutes more. Adjust seasoning and serve hot with crusty bread.
Notes
For a thicker soup, lightly mash a few potatoes before adding cream.
Adjust spice level by adding or reducing Cajun seasoning or red pepper flakes.
Use freshly grated cheese for a smoother melt and richer flavor.
Swap heavy cream for half-and-half for a lighter version.
Reheats beautifully — flavor deepens overnight.
