Ingredients
- 600 grams (4 medium) potatoes, peeled and diced into 2cm (0.8 inch) cubes
- 150 grams (1 large) yellow onion, finely chopped
- 2 cloves garlic, minced
- 150 grams (1 medium) green bell pepper, cored, seeded, and diced
- 100 grams (2 stalks) celery, diced
- 950 milliliters (4 cups) chicken or vegetable broth
- 240 milliliters (1 cup) heavy cream (double cream)
- 2 tablespoons Cajun seasoning (ensure it's fresh and vibrant)
- 1 teaspoon smoked paprika
- Salt, to taste
- Freshly ground black pepper, to taste
- For garnish: 30 grams (1/4 cup) chopped green onions (scallions)
- For garnish (optional): 50 grams (approx. 4-5 slices) crispy crumbled bacon
Instructions
- In a large, heavy-bottomed pot or Dutch oven, heat a tablespoon of olive oil or butter over medium heat. Add the chopped yellow onion, minced garlic, diced bell pepper, and diced celery. Sauté these aromatic vegetables for approximately 5-7 minutes, stirring occasionally, until they have softened and become fragrant without browning. This step builds the foundational flavor of the soup.
- Introduce the diced potatoes, Cajun seasoning, and smoked paprika to the pot. Stir well to ensure the potatoes and vegetables are thoroughly coated with the spices. Pour in the chicken or vegetable broth. Bring the mixture to a rolling boil, then reduce the heat to low, cover the pot, and let it simmer gently for 20-25 minutes, or until the potatoes are fork-tender and easily pierced. The simmering allows the flavors to meld beautifully.
- Carefully remove the pot from the heat. Using an immersion blender, blend the soup directly in the pot until it reaches your desired consistency. For a rustic texture, blend until mostly smooth but leave some small chunks of potato and vegetable intact. For a silky-smooth soup, blend until no lumps remain. Alternatively, you can carefully transfer batches of the soup to a regular blender, blending until smooth, then returning to the pot.
- Stir the heavy cream into the blended soup. Return the pot to medium-low heat and gently heat through for an additional 5 minutes, stirring frequently to prevent scorching, until the soup is hot but not boiling. Taste the soup and adjust the seasoning with salt and freshly ground black pepper as needed. Cajun seasoning can vary in saltiness, so always taste before adding more salt.
- Ladle the Spicy Cajun Potato Soup into warm bowls. Garnish each serving generously with fresh chopped green onions. If desired, sprinkle with crispy crumbled bacon for an extra layer of flavor and texture. Serve immediately and enjoy the comforting warmth and vibrant spice.

Tools You’ll Need
- Large, heavy-bottomed pot or Dutch oven
- Sharp knife
- Cutting board
- Measuring cups and spoons
- Immersion blender (or a regular blender)
- Ladle
- Spatula or wooden spoon
Essential Success Tips
- For best flavor, dice your vegetables uniformly to ensure even cooking. Small dice will cook faster and integrate better into the soup.
- When sautéing the aromatics, allow them to soften thoroughly to release their full flavor potential before adding other ingredients.
- Taste your Cajun seasoning beforehand. Some blends are spicier or saltier than others, which will influence how much you add and how much additional salt and pepper is needed.
- Do not boil the soup after adding the heavy cream; gentle simmering is enough to heat it through and prevent curdling.
- If using a regular blender, fill the blender no more than halfway with hot soup, vent the lid, and cover with a towel to prevent steam buildup and ensure safe blending.
Professional Cooking Secrets
- To deepen the flavor profile, roast your potatoes before adding them to the soup. Toss the diced potatoes with a little olive oil and part of the Cajun seasoning, then roast at 200°C (400°F) for 15-20 minutes until slightly caramelized. This adds an incredible depth and nuttiness.
- Create a 'Cajun Holy Trinity' sofrito by cooking the onion, bell pepper, and celery together until very tender and slightly caramelized before adding garlic. This traditional base is crucial for authentic Cajun flavor.
- For an extra layer of umami, deglaze the pot with a splash of dry white wine or a bit more broth after sautéing the vegetables, scraping up any browned bits from the bottom before adding the main liquid.

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 over low heat, adding a splash of broth or milk if it's too thick.
- Freezing: This soup freezes reasonably well, though the heavy cream might separate slightly upon thawing. Thaw overnight in the refrigerator and whisk vigorously when reheating to re-emulsify.
- Variations: For a smoky flavor, add a diced smoked sausage (like Andouille) along with the vegetables. For a vegetarian version, ensure you use vegetable broth and omit bacon. A pinch of cayenne pepper can be added for extra heat.
Frequently Asked Questions
Can I make this soup less spicy?
Absolutely! The spice level primarily comes from the Cajun seasoning. You can reduce the amount of Cajun seasoning to 1 tablespoon or use a mild blend. You can also omit the smoked paprika if you prefer, though it adds a lovely depth of flavor.
What can I use instead of heavy cream?
For a lighter version, you can use half-and-half or evaporated milk, though the soup will be less rich. For a dairy-free alternative, full-fat coconut milk can provide a similar creaminess, but it will impart a subtle coconut flavor.
Can I add meat to this soup?
Yes, this soup is delicious with added proteins! Cooked andouille sausage, shredded chicken, or even shrimp (added in the last few minutes of cooking) would be excellent additions to make it even heartier.
