Cajun Potato Soup Ingredients

For the Soup

Extra-virgin olive oil – Used for sautéing; it creates a rich flavor base.
Spicy smoked sausage (like andouille) – Adds depth and smokiness; substitute with chorizo or turkey sausage for a lighter option.
Yellow onion – Provides aromatic flavor; shallots can offer a milder taste.
Red bell pepper – Contributes sweetness and vibrant color; can be swapped for yellow or green bell peppers if desired.
Celery – Adds texture and flavor; no substitutes necessary here.
Garlic – Enhances the overall flavor; fresh garlic is preferred for robust aroma.
Homemade Cajun seasoning – Infuses spice and heat; feel free to use store-bought for convenience.
Unsalted butter – Essential for making a roux that thickens the soup; olive oil or margarine can be used in its place.
All-purpose flour – Acts as a thickening agent; gluten-free flour is an excellent substitute if needed.
Low-sodium chicken broth – Forms the savory base of the soup; go for vegetable broth for a vegetarian alternative.
Half and half – Adds creaminess to the dish; switch to heavy cream for richer soup or milk for a lighter version.
Russet potatoes – The star ingredient providing heartiness; Yukon gold or red potatoes work just as well.
Sharp cheddar cheese – Introduces richness and tang; can be substituted with a milder cheese or a dairy-free option for vegans.
Salt and cracked black pepper – Essential seasonings to elevate taste; adjust to your preference.
Fresh chopped parsley – A bright, fresh garnish; completely optional, but adds a nice finishing touch.

Now that you’ve gathered all your ingredients for this delicious Cajun Potato Soup, it’s time to get cooking!

Step‑by‑Step Instructions for Cajun Potato Soup

Step 1: Sauté the Sausage
In a Dutch oven, heat 2 tablespoons of extra-virgin olive oil over medium heat. Add sliced spicy smoked sausage and cook for about 5-7 minutes until browned and slightly crispy. This adds a rich depth to your Cajun potato soup. Once done, remove the sausage from the pot and set it aside, leaving the flavorful drippings for the next step.

Step 2: Cook the Vegetables
In the same pot, add chopped yellow onion, diced red bell pepper, and diced celery. Sauté these aromatic veggies for 2-3 minutes, stirring occasionally, until they soften and the onion turns translucent. Next, add minced garlic and cook for an additional minute until fragrant, enhancing the flavor base of your Cajun potato soup.

Step 3: Create the Roux
Add 3 tablespoons of unsalted butter to the pot, allowing it to melt. Then, sprinkle in ¼ cup of all-purpose flour, stirring constantly for 2-3 minutes until the mixture is a light golden color and the raw flour taste disappears. This roux will give your Cajun potato soup that luscious creamy texture.

Step 4: Add the Broth and Potatoes
Gradually pour in 4 cups of low-sodium chicken broth and 1 cup of half and half, stirring continuously to prevent lumps. Once combined, add 4 cups of cubed russet potatoes along with 2 tablespoons of homemade Cajun seasoning, salt, and pepper to taste. Bring the mixture to a gentle simmer over medium-low heat.

Step 5: Simmer to Perfection
Reduce the heat to low, cover the pot, and let your Cajun potato soup simmer for 20-25 minutes. Stir occasionally until the potatoes are fork-tender and the flavors meld beautifully. The soup should have thickened slightly by this point, creating that comforting and hearty experience everyone loves.

Step 6: Finish with Sausage and Cheese
Stir in the reserved sautéed sausage and 1 cup of shredded sharp cheddar cheese into the pot. Mix well until the cheese has melted and is fully incorporated into the soup, creating an irresistibly creamy texture. Taste and adjust the seasoning as necessary; your delicious Cajun potato soup is nearly ready to serve.

Step 7: Serve and Garnish
Ladle the fragrant Cajun potato soup into bowls, garnishing each with fresh chopped parsley if desired. Serve hot alongside crusty bread or cornbread to soak up every bit of that flavorful broth. Enjoy the warmth and comfort this hearty soup brings to your gathering!

Herb-Infused: Add fresh thyme or rosemary during simmering for a delightful herbal note. These herbs elevate the depth of flavor, making each bowl a delightful experience.

Savory Swap: Try using smoked turkey or ham in place of sausage for a slightly different yet equally delicious flavor profile. This swap still gives that nice smokiness without the spiciness.
Loaded Variation: Top each serving with crispy bacon bits and a dollop of sour cream or Greek yogurt for a richer and more decadent finish. This garnish creates a delightful contrast to the creamy soup base.
