Step-by-Step Instructions

Step 1 — Prepare Your Ingredients

Gather 2 pounds of russet potatoes, peeled and diced into 1-inch cubes, 1 large yellow onion, 1 green bell pepper, 2 celery stalks, 1 pound of andouille sausage, and your Cajun seasoning blend. Having everything prepped and within reach, a technique known as mise en place, makes the cooking process smooth and efficient.

Step 2 — Sauté the Holy Trinity and Sausage

In a large Dutch oven or heavy-bottomed pot, heat 2 tablespoons of oil over medium-high heat. Add the diced onion, bell pepper, and celery (the “Holy Trinity” of Cajun cooking) and sauté for 5-7 minutes until softened. Add the sliced andouille sausage and cook for another 3-4 minutes until it begins to brown, releasing its smoky oils into the vegetables.

Step 3 — Build the Flavor Base

Stir in 3 minced garlic cloves and cook for 1 minute until fragrant. Sprinkle in 2 tablespoons of Cajun seasoning and 1/4 cup of all-purpose flour, stirring constantly to coat everything. Cook for 2 minutes to remove the raw flour taste, which will also help thicken your Cajun Potato Soup later.

Step 4 — Deglaze and Add Liquids

Pour in 4 cups of chicken broth and use a wooden spoon to scrape up any browned bits from the bottom of the pot—this is packed with flavor. Add the diced potatoes and 2 cups of water, then bring the mixture to a boil.

Step 5 — Simmer Until Potatoes Are Tender

Once boiling, reduce the heat to medium-low, cover the pot, and let it simmer for 15-20 minutes. The soup is ready when the potatoes are easily pierced with a fork but not yet falling apart. This gentle simmer allows the potatoes to cook through without breaking down completely.

Step 6 — Creamify the Soup

Reduce the heat to low. Stir in 1 cup of heavy cream and 1 cup of whole milk. Warm the soup through for about 5 minutes, but do not let it come to a boil after adding the dairy to prevent curdling. For a lighter version, you can substitute half-and-half.

Step 7 — Final Seasoning and Serve

Taste the soup and adjust the seasoning with salt, black pepper, and more Cajun seasoning if desired. For an extra kick, add a pinch of cayenne pepper. Ladle the hot, creamy Cajun Potato Soup into bowls and garnish with sliced green onions and a dash of hot sauce.

Common Mistakes to Avoid

• Mistake: Using pre-shredded cheese, which contains anti-caking agents. Fix: Shred a block of sharp cheddar yourself for a smoother, creamier melt.
• Mistake: Over-blending the potatoes until they become gluey. Fix: Mash by hand or pulse briefly with an immersion blender for a heartier texture.
• Mistake: Adding Cajun seasoning only at the end. Fix: Bloom the spices in the hot oil with the trinity to build a deeper, more complex flavor base.
• Mistake: Using a weak, store-bought broth. Fix: Opt for a low-sodium chicken or vegetable stock and control the salt yourself with Cajun seasoning.
• Mistake: Skipping the roux, leading to a thin, watery soup. Fix: Cook equal parts fat and flour until nutty brown to properly thicken your Cajun Potato Soup.
• Mistake: Overcrowding the pot when sautéing the holy trinity. Fix: Cook the onions, celery, and bell peppers in batches if needed to ensure they caramelize, not steam.
• Mistake: Not tasting and adjusting seasoning after adding potatoes. Fix: Potatoes absorb salt, so always do a final taste test and adjust Cajun spice and salt levels before serving.
• Mistake: Using waxy potatoes like red potatoes that don’t break down. Fix: Choose starchy potatoes like Russets or Yukon Golds for a creamier consistency.

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 space for expansion, and freeze for up to 3 months.
• Reheat: Thaw frozen soup in the refrigerator overnight. Reheat gently on the stovetop or in the microwave, stirring occasionally, until it reaches an internal temperature of 165°F.

For the best texture, give your Cajun Potato Soup a good stir after reheating, as the potatoes may have absorbed some liquid.
