Step-by-Step Instructions

Step 1 — Prepare the Vegetables

Dice one large onion, two celery stalks, and one green bell pepper. This classic Cajun holy trinity forms the flavor base for your soup. Mince three cloves of garlic and set aside.

Step 2 — Sauté the Aromatics

In a large Dutch oven or heavy-bottomed pot, heat two tablespoons of oil over medium heat. Add the holy trinity and sauté for 5-7 minutes until the vegetables are softened. Add the minced garlic and cook for another minute until fragrant.

Step 3 — Add Spices and Potatoes

Stir in two tablespoons of Cajun seasoning, one teaspoon of smoked paprika, and a pinch of cayenne for extra heat. Add two pounds of peeled and cubed russet potatoes, stirring to coat them in the spices.

Step 4 — Pour in Broth and Simmer

Pour in six cups of chicken or vegetable broth and bring the mixture to a boil. Reduce the heat to a gentle simmer, cover the pot, and cook for 15-20 minutes until the potatoes are fork-tender.

Step 5 — Partially Blend the Soup

Using an immersion blender, partially blend the soup to thicken it while leaving some potato chunks for texture. Alternatively, transfer about two cups of the soup to a standard blender, blend until smooth, and stir it back into the pot.

Step 6 — Add Cream and Sausage

Stir in one cup of heavy cream or half-and-half. Add 12 ounces of sliced andouille sausage that has been browned in a separate skillet. Let the soup simmer for another 5 minutes to heat through.

Step 7 — Adjust Seasoning and Serve

Taste the Cajun Potato Soup and adjust seasoning with salt, black pepper, or more Cajun spice to your preference. Ladle into bowls and garnish with sliced green onions and a sprinkle of parsley.

Common Mistakes to Avoid

• Mistake: Using raw flour for the roux, which can result in a pasty, uncooked flavor. Fix: Cook the roux over medium heat, stirring constantly, until it reaches a rich peanut butter color for a nutty, deep base.
• Mistake: Overcrowding the pot with potatoes, leading to uneven cooking and a mushy texture. Fix: Cut potatoes into uniform ½-inch cubes to ensure they cook evenly and maintain some structure.
• Mistake: Adding dairy too early or at a boil, causing it to curdle and separate. Fix: Temper cream or milk by stirring in a small amount of hot soup first, then incorporate it off the heat.
• Mistake: Underseasoning, as potatoes absorb a lot of salt and spices. Fix: Season in layers, tasting and adjusting after each major addition, especially before serving.
• Mistake: Using pre-shredded cheese, which contains anti-caking agents that can make the soup grainy. Fix: Always shred cheese from a block for a smoother, creamier melt.
• Mistake: Skipping the holy trinity (onion, celery, bell pepper), which is essential for authentic Cajun flavor depth. Fix: Sauté the trinity until softened to build a complex flavor foundation.
• Mistake: Boiling the soup vigorously after adding ingredients, which can break down the potatoes. Fix: Simmer gently once potatoes are added to keep them intact and prevent burning.
• Mistake: Not using a quality Cajun seasoning blend, resulting in a flat, one-dimensional spice profile. Fix: Opt for a salt-free blend to control sodium, or make your own with paprika, garlic powder, onion powder, cayenne, and oregano.

Storing Tips

• Fridge: Cool your Cajun Potato Soup completely, then store in an airtight container for up to 4 days.
• Freezer: Portion the soup into freezer-safe bags or containers, leaving some space for expansion, and freeze for up to 3 months.
• Reheat: Thaw frozen soup overnight in the refrigerator. Reheat gently on the stovetop or in the microwave, stirring occasionally, until it reaches an internal temperature of 165°F (74°C).

For the best texture, give your reheated Cajun Potato Soup a good stir, as the potatoes may have absorbed some liquid. You can add a splash of broth or cream to bring it back to your desired consistency.
