- 960 ml (4 cups) low-sodium chicken broth

- 15 ml (1 tablespoon) olive oil

Instructions
- Begin by meticulously preparing your vegetables and sausage. Dice approximately 900 grams (4 cups) of Yukon Gold or red potatoes into uniform 1.5 cm (0.6 inch) cubes to ensure even cooking. Finely chop 1 large yellow onion (about 240 grams or 1 cup), 1-2 bell peppers (about 150 grams or 1 cup), and 2-3 celery stalks (about 120 grams or 1 cup). Mince the 3 cloves of fresh garlic. Lastly, slice 340 grams (12 oz) of andouille sausage into bite-sized rounds, about 0.5 cm (0.2 inch) thick, which will brown beautifully and integrate well into the soup.
- In a large, heavy-bottomed pot or Dutch oven, heat 28 grams (2 tablespoons) of unsalted butter and 15 ml (1 tablespoon) of olive oil over medium heat. Once the butter is melted and shimmering, add the sliced andouille sausage. Cook the sausage for 5-7 minutes, stirring occasionally, until it is nicely browned and has released its aromatic oils. Remove the cooked sausage with a slotted spoon and set it aside, leaving the flavorful drippings in the pot.
- Add the chopped onions, celery, and bell peppers to the same pot with the sausage drippings. Sauté these aromatics over medium heat for 5-7 minutes, stirring occasionally, until they have softened and become translucent. This step is crucial for building a deep flavor base. Stir in the minced garlic during the last 30 seconds of cooking, being careful not to burn it, as burnt garlic can turn bitter.
- Return the browned andouille sausage to the pot with the softened vegetables. Sprinkle 30 ml (2 tablespoons) of Cajun seasoning over everything, stirring well to ensure all the ingredients are evenly coated and the spices are fragrant. Add the diced potatoes and pour in 960 ml (4 cups) of chicken broth. Bring the mixture to a rolling boil, then reduce the heat to a gentle simmer. Cook uncovered for about 15-20 minutes, or until the potato cubes are fork-tender, indicating they are ready for the next step.
- For that signature creamy texture, use an immersion blender to puree a portion of the soup directly in the pot. Blend until you achieve your desired consistency, leaving some potato chunks intact if you prefer a heartier bite. If you do not have an immersion blender, carefully transfer about one-third to one-half of the soup to a regular blender and pulse until smooth, then return the pureed mixture to the pot.
- Finally, stir in 240 ml (1 cup) of heavy cream or half and half. Warm the soup gently over low heat, stirring occasionally, until it is heated through. Avoid boiling the soup once the cream is added, as this can cause it to separate. Taste the soup and adjust the seasoning with salt, freshly ground black pepper, or additional Cajun spices if you desire more heat and flavor. Ladle into bowls and garnish generously with sliced green onions or chives, and any other optional toppings like shredded cheese or crispy bacon bits.
Tools You’ll Need

- Wooden spoon or sturdy spatula
- Immersion blender (or regular blender)
Essential Success Tips
- Uniform Potato Dicing: Ensure your potato cubes are roughly the same size to guarantee even cooking. This prevents some pieces from being mushy while others are still firm.
- Don't Skip the Browning: Fully browning the andouille sausage before adding other ingredients deepens its flavor and renders out some fat, which then flavors the entire soup base.
- Toast Your Spices: Adding the Cajun seasoning to the pot with the vegetables and sausage before the broth allows the spices to toast slightly, intensifying their aroma and flavor.
- Gentle Simmering: Once the broth is added, maintain a gentle simmer. A rapid boil can break down the potatoes too quickly and make the soup starchy.
- Avoid Boiling After Cream: After adding the heavy cream or half and half, warm the soup gently over low heat. Boiling dairy can cause it to curdle or separate, compromising the soup's smooth texture.
Professional Cooking Secrets
- Build a Fond: After browning the sausage and sautéing the aromatics, deglaze the pot with a splash of chicken broth or even a dry white wine (before adding the bulk of the broth) to scrape up any flavorful browned bits stuck to the bottom. This 'fond' adds immense depth of flavor.
- Roast Your Veggies: For an even richer, deeper flavor profile, consider roasting the diced potatoes, onions, bell peppers, and celery slightly before adding them to the pot. A quick roast with a drizzle of olive oil can bring out their natural sweetness and add complexity.
- Layer the Heat: If you want more control over the spice level, add half the Cajun seasoning initially, and then taste before adding more at the end. You can also add a pinch of cayenne pepper with the garlic if you desire a truly fiery kick.
Notes
- Storage: Leftover soup can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently on the stovetop or in the microwave.
- Freezing: This soup freezes well without the cream. If planning to freeze, cook the soup, blend, and cool completely before freezing. Add the cream upon reheating. Thaw overnight in the refrigerator before gently reheating.
- Variations: For a vegetarian version, omit the sausage, use vegetable broth, and consider adding smoked paprika for a smoky flavor. You can also add other vegetables like corn or spinach.
Frequently Asked Questions
Can I use a different type of sausage?
Yes, while andouille sausage provides an authentic Cajun smoky flavor and spice, you could substitute it with another smoked sausage like kielbasa or even a spicy Italian sausage for a different but equally delicious profile. Adjust Cajun seasoning as needed if your sausage is very mild or very spicy.
What kind of potatoes are best for this soup?
Yukon Gold potatoes are highly recommended because their waxy-starchy texture holds its shape well when diced, yet they become incredibly creamy when partially blended. Red potatoes also work similarly well. Avoid overly starchy potatoes like Russets, which can become too mushy, or very waxy potatoes which might not blend as smoothly.
How can I make this soup thicker?
To make the soup thicker, you can blend a larger portion of the cooked potatoes, or even all of them, to create a denser base. Alternatively, you could create a roux by whisking 15-30 grams (1-2 tablespoons) of flour with the butter and oil after cooking the sausage but before adding the vegetables, then slowly whisk in the broth.
