Ingredients

- 1 large yellow onion, diced (about 200 g)
- 20 g (4 cloves) garlic, minced
- 1 red bell pepper, diced (about 150 g)
- 1 green bell pepper, diced (about 150 g)
- 450 grams (1 pound) red potatoes, diced into 1.25 cm (½-inch) cubes (skin on)
- 340 grams (12 oz) Cajun sausage or spicy sausage (like Andouille or kielbasa), sliced into 0.6 cm (¼-inch) rounds
- 5 g (1 teaspoon) smoked paprika
- 2 g (1 teaspoon) dried thyme
- 5 g (1 teaspoon) Cajun seasoning (store-bought or homemade)
- 1 g (½ teaspoon) crushed red pepper flakes (optional, for more heat)
- 950 ml (4 cups) chicken broth (preferably low sodium)
- 240 ml (1 cup) heavy cream
- 120 ml (½ cup) whole milk
- Salt and freshly ground black pepper to taste
- 2 green onions, chopped (for garnish)
- Chopped fresh parsley for garnish
- Optional add-in: 200 grams (1 cup) corn kernels
- Optional add-in: 100 grams (1 cup) shredded cheddar cheese
Instructions
- Sauté the Base. Start by heating the olive oil and butter in a large, heavy-bottomed pot or Dutch oven over medium heat. Once the butter is melted and shimmering, add the diced yellow onions. Sauté for approximately 5 minutes, stirring occasionally, until the onions become translucent and soft, releasing their natural sweetness. This forms the foundational aromatic layer of the soup.
- Infuse Aromatics. Add the minced garlic, diced red bell pepper, and diced green bell pepper to the pot with the softened onions. Continue to sauté for another 3 to 4 minutes, stirring frequently. This step allows the bell peppers to soften slightly and their vibrant, sweet flavors to meld with the pungent garlic, creating the signature Cajun aromatic trinity.
- Brown the Cajun Sausage. Introduce the sliced Cajun sausage (or your chosen spicy sausage like Andouille or kielbasa) directly into the pot. Increase the heat slightly to medium-high if needed. Let the sausage brown for 5 to 7 minutes, stirring occasionally. The goal is to develop a nice crispness and caramelization on the edges of the sausage rounds, which intensifies their smoky, savory flavor and contributes a deep, rich undertone to the soup.
- Spice It Up. Reduce the heat back to medium. Sprinkle in the smoked paprika, dried thyme, Cajun seasoning, and the optional crushed red pepper flakes. Stir everything thoroughly for about 1 minute, ensuring all the ingredients are coated in the spices. Toasting the spices briefly in the hot oil and sausage drippings helps to bloom their flavors, making them more aromatic and potent.
- Add Potatoes and Broth. Add the diced red potatoes to the spiced sausage and vegetable mixture. Pour in the chicken broth, ensuring all the solids are submerged. Give it a good stir to combine. Bring the mixture to a rolling boil over medium-high heat.
- Simmer to Tenderness. Once boiling, reduce the heat to low, cover the pot loosely, and let the soup simmer gently for about 20 to 25 minutes. Continue simmering until the red potatoes are fork-tender but still hold their shape; you don't want them to become mushy. This slow simmer allows the flavors to deepen and the potatoes to absorb the rich broth.
- Incorporate Cream and Finish. Stir in the heavy cream and whole milk. Allow the soup to return to a gentle simmer for another 5 minutes, stirring occasionally. This step allows the dairy to warm through and the soup to thicken slightly to a luxurious consistency. Taste the soup and adjust the seasoning with salt and freshly ground black pepper as needed. If you are using the optional corn kernels or shredded cheddar cheese, stir them in now and continue to simmer for an additional 2 minutes, until they are heated through and the cheese is melted, if applicable.
- Serve Hot and Garnish. Ladle the rustic Cajun red potato soup generously into individual serving bowls. Garnish each bowl with a sprinkle of chopped green onions and fresh parsley for a burst of color and herbaceous freshness. Serve immediately with crusty bread or warm cornbread for a truly comforting and satisfying meal.

Essential Success Tips
- Ensure your bell peppers and onions are diced evenly for consistent cooking.
- Don't rush browning the sausage; this step is crucial for developing deep, smoky flavor.
- Use low-sodium chicken broth so you can control the final saltiness of the soup.
- Simmer the potatoes until just fork-tender to prevent them from becoming mealy.
- Always taste and adjust seasoning (salt, pepper, and even a pinch more Cajun seasoning) before serving.
Professional Cooking Secrets
- For an extra layer of complexity, slightly char the bell peppers under a broiler before dicing and adding them to the pot.
- If you have a little extra time, make your own Cajun seasoning blend to control the spice level and freshness of the herbs.
- To achieve an even thicker, more velvety texture without adding more cream, mash a portion of the cooked potatoes against the side of the pot before stirring in the cream and milk.
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.
- Variations: Feel free to experiment! For a vegetarian version, omit the sausage and use vegetable broth, adding smoked paprika for depth. A squeeze of fresh lemon juice at the end can brighten the flavors.
- Optional Add-ins: For a sweeter note and textural contrast, stir in corn kernels. For an even creamier, cheesier soup, shredded cheddar cheese can be melted in at the end.
Frequently Asked Questions
Can I make this soup spicier?
Absolutely! You can increase the amount of crushed red pepper flakes or add a dash of your favorite hot sauce when serving. Using a spicier Cajun sausage will also contribute more heat.
What kind of potatoes are best for this soup?
Red potatoes are ideal because they hold their shape well during simmering and have a pleasant, slightly waxy texture. Yukon Gold potatoes are another excellent choice for similar reasons. Russet potatoes tend to break down too much.
Can I freeze this soup?
While possible, soups with a high dairy content like this one can sometimes separate or become grainy after freezing and thawing. If you plan to freeze, it's best to freeze the soup before adding the heavy cream and milk, then stir them in during reheating.
