Step-by-Step Instructions

Prep and Brown the Sausage:
Add vegetable oil to a large pot and heat over medium Cook the sliced andouille sausage in the hot oil stirring every minute or so Allow every piece to become browned and slightly crisp on the edges This releases the sausage’s spicy fat which becomes your flavor starter Once browned remove the sausage with tongs or a slotted spoon and set it aside in a bowl This keeps the sausage juicy and lets you build more flavor in the same pot
Sauté the Vegetables:
With the sausage out of the pot add diced onion celery and red bell pepper to the remaining oils and sausage bits Lower the heat if needed so the vegetables gently soften without browning Stir often for about six minutes until the onion looks translucent and the mix is fragrant At this point add minced garlic and keep cooking for another minute until you can smell the garlic but be careful not to let it brown
Simmer the Soup:
Sprinkle Cajun seasoning kosher salt black pepper paprika and cayenne into the sautéed vegetables and stir until everything is coated Pour in chicken broth scraping the bottom of the pot to release any stuck bits Add the cubed potatoes and raise heat to bring everything to a gentle simmer Lower the heat so the soup just barely bubbles Cover and cook for twenty minutes stirring once or twice The potatoes are ready when a fork slides in easily but they are not falling apart
Finish and Serve:
Return the cooked sausage and any juices to the pot Pour in the heavy cream and sprinkle in the shredded cheddar Stir so the cheese melts evenly and the soup becomes thick creamy and smooth Let everything bubble very gently for about five more minutes Taste and add more salt if needed Sprinkle fresh parsley across the top and serve the soup warm with crusty bread on the side

I absolutely love how the cream and cheddar turn the soup into pure comfort My kids always compete over who gets the biggest scoop of sausage and that has become a little family joke whenever I serve this dish

Storage Tips

Refrigerate leftovers in an airtight container for up to three days The soup thickens slightly in the fridge so when reheating add a splash of chicken broth or a spoon of cream to loosen it up Avoid freezing with cream and cheese as the texture may become grainy

Ingredient Substitutions

No andouille sausage Use smoked kielbasa or chorizo for similar depth Want it vegetarian Skip the sausage and use extra bell peppers and smoked paprika for body You can swap cheddar for Monterey jack or pepper jack if you want more melt and spice

Serving Suggestions

I like to serve Cajun potato soup with toasted garlic bread or a hot biscuit A side salad of greens with a simple vinaigrette balances the creaminess The soup works beautifully in bread bowls for an extra rustic touch
