Ingredients List

• 2 tablespoons (30ml) olive oil or unsalted butter
• 1 lb (450g) andouille sausage, sliced into 1/4-inch rounds
• 1 large yellow onion, diced
• 1 green bell pepper, diced
• 2 celery stalks, diced
• 4 cloves garlic, minced
• 1/4 cup (30g) all-purpose flour
• 2 tablespoons Cajun seasoning (use a salt-free blend if possible, to control sodium)
• 6 cups (1.4 liters) low-sodium chicken or vegetable broth
• 2 lbs (900g) Russet potatoes, peeled and cut into 1/2-inch cubes
• 1 cup (240ml) heavy cream
• Salt and freshly ground black pepper, to taste
• 1/2 cup sliced green onions, for garnish
• Shredded sharp cheddar cheese, for garnish (optional)

Step-by-Step Instructions

1. Brown the Sausage: Heat the olive oil in a large Dutch oven or heavy-bottomed pot over medium-high heat. Add the sliced andouille sausage and cook, stirring occasionally, until well-browned and crispy on the edges, about 5-7 minutes. Use a slotted spoon to remove the sausage and set it aside on a plate, leaving the flavorful rendered fat in the pot.
2. Sauté the Trinity: Reduce the heat to medium. Add the diced onion, bell pepper, and celery (the Cajun holy trinity) to the pot. Cook, stirring frequently, until the vegetables have softened, about 6-8 minutes. Scrape up any browned bits from the bottom of the pot.
3. Build the Flavor Base: Stir in the minced garlic and cook until fragrant, about 1 minute. Sprinkle the flour and Cajun seasoning over the vegetables. Cook, stirring constantly for 2 minutes to cook out the raw flour taste. This step is crucial for thickening the soup.
4. Combine and Simmer: Slowly pour in one cup of the chicken broth, whisking constantly to create a smooth paste with no lumps. Once smooth, gradually whisk in the remaining broth. Add the cubed potatoes and bring the mixture to a boil.
5. Cook the Potatoes: Once boiling, reduce the heat to a gentle simmer. Cover the pot and cook for 15-20 minutes, or until the potatoes are fork-tender.
6. Create the Creamy Texture: Use a potato masher or the back of a large spoon to gently mash about one-third of the potatoes directly in the pot. This thickens the soup naturally, giving it a wonderful rustic texture.
7. Finish the Soup: Turn off the heat. Slowly stir in the heavy cream and the cooked andouille sausage. The foundation of any great Cajun Potato Soup is building layers of flavor right from the start, and this final step brings it all together.
8. Season and Serve: Taste the soup and season generously with salt and pepper as needed. Remember, potatoes absorb a lot of salt. Ladle the hot soup into bowls and garnish with fresh green onions and shredded cheddar cheese, if desired.

Expert Tips for the Perfect Cajun Potato Soup

• Use Russet Potatoes: For a truly creamy soup, Russet potatoes are non-negotiable. Their high starch content breaks down beautifully during cooking, creating a natural thickness that waxy potatoes like red or Yukon Gold simply cannot replicate.
• Don’t Boil the Cream: When adding the heavy cream at the end, make sure the heat is off or very low. Boiling dairy can cause it to curdle, ruining the soup’s silky texture. Stir it in gently until just combined.
• Toast Your Spices: For an even deeper flavor profile, add your Cajun seasoning along with the garlic and cook for 30-60 seconds until fragrant before adding the liquid. This simple chef’s trick awakens the essential oils in the spices.
• Deglaze for Flavor: After you sauté the vegetables, you’ll see browned bits (called “fond”) stuck to the bottom of the pot. When you add the first splash of broth, use a wooden spoon to scrape these bits up. This is pure, concentrated flavor that will elevate your entire dish.

Common Mistakes to Avoid

Prevent common issues with these simple tips:

• Scorching the roux: When you add the flour, keep the heat on medium-low and stir constantly. A burnt roux will make the entire pot of soup taste bitter.
• Using waxy potatoes: Using potatoes like red bliss or fingerlings will result in firm chunks of potato in a thin broth, rather than the desired creamy consistency.
• Adding cold cream to a boiling soup: This temperature shock can cause the cream to separate or curdle. Ensure the soup is at a gentle simmer or turn the heat off before stirring in the cream.
• Under-seasoning: Potatoes are flavor sponges and require a significant amount of salt to taste properly seasoned. Always taste and adjust the salt and pepper right before serving.

Storing Tips for the Recipe

Proper storage ensures your delicious creation can be enjoyed later:

• Refrigeration: Allow the soup to cool completely before transferring to an airtight container. It will keep in the refrigerator for up to 4 days. Reheat gently on the stovetop over low heat, stirring occasionally. Avoid microwaving, as it can make the potatoes rubbery.
• Freezing: While soups with dairy and potatoes can sometimes have a slight texture change upon thawing, this one freezes reasonably well. Cool completely, then store in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating.
• Make-ahead option: You can save time by chopping the onion, bell pepper, and celery up to 2 days in advance. Store them in an airtight container in the refrigerator.

Frequently Asked Questions (FAQs)

Can I make this Cajun Potato Soup vegetarian or vegan?

Absolutely. To make it vegetarian, simply omit the andouille sausage and use a full-flavored vegetable broth. You can add a teaspoon of smoked paprika to replicate the smoky flavor. For a vegan version, use olive oil instead of butter, omit the sausage, use vegetable broth, and substitute the heavy cream with a full-fat oat milk or a cashew cream for richness.

How can I adjust the thickness of the soup?

You have complete control over the consistency. If you prefer a thicker soup, use your potato masher to break down more of the potatoes. You can also let it simmer uncovered for an extra 5-10 minutes to allow some liquid to evaporate. For a thinner soup, simply stir in a splash more broth or cream until you reach your desired texture.
