Before You Start
- Choose the Right Potatoes: Russet potatoes are perfect for this soup because they become wonderfully tender and add a creamy texture. Yukon Golds work great too.
- Slice Sausage Evenly: Make sure to slice your sausage uniformly. This ensures they cook evenly and release their smoky flavor throughout the soup.
- Don’t Rush the Sauté: Take your time to cook the onions, bell peppers, and celery until they’re nice and soft. This builds a flavorful base for your soup.
- Adjust the Heat: Cajun seasoning can vary in spiciness. Start with a couple of tablespoons and add more to taste if you like it hotter, or keep it mild if you’re watching the heat.
- Blend for Creaminess: For an extra creamy soup, use an immersion blender to partially blend the soup directly in the pot. This thickens it up without losing any of the hearty chunks.
- Prep Ahead: Chop all your vegetables and slice the sausage the night before to save time during the week. Just store them in the fridge until you’re ready to cook.

Ingredients You’ll Need
- Butter – You’ll need unsalted butter. If you’re out of butter, you can easily swap in olive oil or margarine.
- Onion, Garlic, Bell Pepper and Celery – My vegetables of choice that make a great base for this soup.
- Smoked Sausage – You can use Andouille sausage, or any other smoked sausage.
- Russet Potatoes – These are perfect for creating a creamy, hearty texture in the soup. If you prefer, Yukon Gold potatoes are a great substitute for a slightly buttery flavor.
- Chicken Broth – I use low-sodium or no-sodium chicken broth to control the saltiness, but vegetable broth works just as well, especially for a lighter or vegetarian version.
- Heavy Cream or Half-and-Half – This adds creaminess and richness to the soup. For a lighter version, you can use milk or a dairy-free alternative like coconut milk.
- All-Purpose Flour – Helps thicken the soup and create a smooth texture. If you need a gluten-free option, cornstarch mixed with a bit of water works just as well.
- Worcestershire Sauce – Brings a savory umami kick to the soup. If you don’t have it, a splash of soy sauce can provide a similar depth of flavor.
- Cajun Seasoning – Delivers the signature spicy kick that defines the soup. If you don’t have Cajun seasoning, you can make your own using my recipe.

Melt 4 tablespoons of unsalted butter in a large pot or Dutch oven over medium heat. Add the diced yellow onion, diced green bell pepper, and diced celery. Cook until the vegetables are softened and fragrant, about 5-7 minutes. Then, stir in the minced garlic and cook for an additional minute.

Add the sliced andouille or smoked sausage to the pot. Cook until the sausage is browned and releases its smoky flavor, about 5 minutes.

Sprinkle 2 tablespoons of all-purpose flour over the mixture. Stir continuously for about 2 minutes to eliminate the raw flour taste. Then, add the 2 tablespoons of Cajun seasoning and mix well to combine all the spices.

Stir in the diced russet potatoes and pour in the 4 cups of chicken broth. Scrape the bottom of the pot to release any browned bits. Bring the soup to a boil, then reduce the heat to low. Cover and let it simmer for 20-25 minutes, or until the potatoes are tender.

For a creamier texture, use an immersion blender to puree a portion of the soup directly in the pot. Alternatively, remove about 2 cups of the soup, blend until smooth, and return it to the pot. Be careful when blending hot liquids.

Stir in the 1 cup of heavy cream or half-and-half and add the 1 teaspoon of Worcestershire sauce. Taste and adjust the seasoning with additional Cajun seasoning or salt if needed. Simmer uncovered for an additional 5 minutes to let the flavors meld. Garnish with fresh parsley and serve.
