Ingredients
Base
- 2 tbsp olive oil
- 2 tbsp unsalted butter, room temperature butter, cut into pieces
- 1 large yellow onion, finely diced
- 2 stalks celery, finely diced
- 2 medium carrots, peeled and diced
- 4 cloves garlic, minced
- 1 lb Yukon Gold potatoes, peeled and cut into 1/2-inch cubes (uniform size for even cooking)
- 4 cups low-sodium chicken or vegetable stock, hot
Seasoning & Sauce
- 1½–2 tbsp Cajun seasoning (adjust to taste)
- 1 tsp smoked paprika
- 1 bay leaf
- 1 cup heavy cream, warmed slightly (to avoid chilling the soup)
- 2 tsp Dijon mustard
Topping & Finish
- 4 slices thick-cut bacon, crisped and chopped
- 2 tbsp fresh parsley, finely chopped
- 2 scallions, thinly sliced
- 1–2 tsp sherry vinegar or lemon juice, to taste
- Salt and freshly ground black pepper, to taste
How to Make Spicy Cajun Potato Soup:
- Prepare mise en place: dice vegetables, cube potatoes evenly, and warm the stock so it won’t shock the pot.
- Tip: Warm stock speeds cooking and keeps texture consistent.
- Heat olive oil and room temperature butter in a heavy-bottomed pot over medium heat until butter foams and scent is nutty. Add onion, celery, and carrots. Sauté until translucent and slightly caramelized at the edges — about 6–8 minutes. Look for glossy vegetables and a sweet aroma.
- Stir in garlic and toast briefly for 30 seconds until fragrant. Sprinkle in Cajun seasoning and smoked paprika; stir to coat the vegetables and bloom the spices. Mini-tip: Toast spice for richer flavor — it should smell toasty, not bitter.
- Add potatoes and bay leaf, then pour in the hot stock to cover. Increase heat to bring to a gentle boil, then reduce to a simmer. Cook until potatoes are tender throughout, about 12–15 minutes; test by piercing a cube for a buttery fork slide.
- Remove bay leaf. For a partially smooth texture, use an immersion blender to purée 50–70% of the soup directly in the pot, leaving some potato chunks for body. If you prefer completely smooth, blend until silky. Professional tip: Deglaze the pan first with a splash of stock to capture browned bits before blending.
- Stir in warm heavy cream and Dijon mustard. Heat gently until the soup shimmers and is slightly thickened — do not boil after adding cream. Adjust seasoning with salt and pepper, tasting for balance between heat and creaminess.
- Finish with 1–2 teaspoons sherry vinegar or lemon juice to lift the flavors. Fold in half the chopped bacon for texture contrast.
- Serve hot, garnished with remaining bacon, scallions, and parsley. If you like richer variations, explore our cheesy beef and potato soup for inspiration on adding umami and cheese finishes.
How to Serve Spicy Cajun Potato Soup:
Present the soup in warmed shallow bowls so the aroma rises. Spoon a small pool of cream in the center, then top with crisp bacon and a scattering of scallions and parsley for color contrast. For a refined touch, serve with thin slices of grilled sourdough brushed with garlic oil or a small quenelle of cultured butter.
How to Store Spicy Cajun Potato Soup:
Cool the soup slightly at room temperature for no more than 1 hour, then transfer to airtight containers. Refrigerate for up to 4 days. To preserve texture, store a small portion of diced cooked potato or extra cream separately and stir in when reheating. Reheat gently over low heat, adding a splash of stock or cream to restore silkiness; avoid rapid boiling to prevent separation.
Tips to Make Spicy Cajun Potato Soup:
- Use Yukon Gold potatoes for a naturally creamy mouthfeel; they break down subtly while keeping structure.
- Toast spices in the pan with the vegetables to fully release aromatics.
- Warm dairy before adding to prevent curdling and to keep the soup glossy.
- Reserve some crispy bacon to add at the last moment for a crisp contrast to the silky soup.
Variation (if any):
- Seafood Twist: Add seared scallops or shrimp in the final minutes and finish with a micro-herb garnish for a coastal interpretation.
- Truffle Finish: For an upscale finish, drizzle a few drops of white truffle oil and top with fried leeks.
- Vegetarian: Use vegetable stock and smoked paprika plus a splash of soy sauce or miso for umami instead of bacon.
FAQs
How spicy is this soup?
Spice level is adjustable. The recipe uses 1½–2 tablespoons of Cajun seasoning for a pronounced but balanced heat. Reduce to 1 tablespoon for milder flavor or increase and add cayenne for more intensity.
Can I make this soup ahead of time?
Yes. The base can be made a day ahead and refrigerated. Reheat gently and refresh with a splash of stock or cream and a final brightener (vinegar or lemon) before serving.
Is it okay to freeze the soup?
You can freeze the soup without cream for up to 3 months. Thaw overnight in the refrigerator, reheat, then stir in warmed cream to restore richness and mouthfeel.
