Step-by-Step Instructions

Brown the Sausage:
Warm oil in a large pot on medium heat until the surface shimmers. Add sliced sausage and cook for about four minutes. Stir now and then to ensure all rounds brown evenly plus you want those flavorful bits stuck to the pan. Move sausage out and set aside but leave the flavorful fat behind.
Sauté the Vegetables:
In that same pot with sizzling sausage drippings add onion celery and red bell pepper. Stir often as vegetables soften over five to eight minutes. Drop in freshly minced garlic for the last minute. The aroma will be vibrant and sweet.
Simmer the Base:
Add Cajun seasoning salt black pepper paprika and cayenne directly to the softened vegetables. Stir a minute so the spices bloom in the hot oil. Pour in chicken broth and gently slide in cubed potatoes. Bring to a steady simmer then lower the heat. Cook for twenty to twenty five minutes. The potatoes should be so tender a fork slides right through.
Finish with Cream and Cheese:
Return the browned sausage to the bubbling pot. Now pour in heavy cream and sprinkle in the cheddar cheese. Stir until the cheese is fully melted. Let this mixture bubble gently five more minutes until thickened and glossy.
Garnish and Serve:
Ladle the soup into bowls and shower with chopped parsley for a fresh finish. Serve steaming hot and savor right away.

Storage Tips

Leftovers keep beautifully in an airtight container for up to three days in the fridge. The soup thickens as it sits but a splash of broth or water restores its creamy texture. If freezing portion into small containers and reheat gently to avoid curdling the cream.

Ingredient Substitutions

No andouille sausage Use smoked kielbasa or chorizo for a good substitute. If you want less heat try turkey sausage. The potatoes can be swapped for Yukon Golds if you like a silkier finish. Low sodium chicken broth also works if you want use less salt.

Serving Suggestions

Serve rustic hunks of bread or warm cornbread on the side for dipping. It pairs perfectly with a crisp green salad or classic coleslaw for balance. Sometimes I set out extra cheddar and hot sauce for those who like even more zip.

Cajun Roots

Cajun cuisine grew out of French Canadian settlers mixing European flavors with ingredients and spice from Louisiana’s bayous. The magic comes from rich sausage punchy seasoning fresh bell peppers and the patient simmer that transforms simple food into something celebratory.
