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, 4 cloves of garlic, and 1 pound of andouille sausage. Having all your ingredients prepped and measured beforehand, a technique known as mise en place, makes the cooking process for this Fall-Inspired Hearty Cajun Potato Soup smooth and efficient.

Step 2 — Sauté the Aromatics and Sausage

In a large Dutch oven or heavy-bottomed pot, heat 2 tablespoons of olive oil over medium-high heat. Add the sliced andouille sausage and cook for 4-5 minutes until browned. Remove the sausage with a slotted spoon and set aside, leaving the rendered fat in the pot.

Add the diced onion, bell pepper, and celery (the “Holy Trinity” of Cajun cooking) to the pot. Sauté for 6-7 minutes until the vegetables have softened. Add the minced garlic and cook for another minute until fragrant.

Step 3 — Build the Soup Base

Sprinkle in 2 tablespoons of all-purpose flour and stir constantly for 1-2 minutes to cook out the raw flour taste. This will help thicken your Fall-Inspired Hearty Cajun Potato Soup. Slowly pour in 4 cups of chicken broth and 2 cups of water, whisking continuously to prevent any lumps from forming.

Step 4 — Add Potatoes and Seasonings

Add the diced potatoes to the pot along with 2 teaspoons of Cajun seasoning, 1 teaspoon of smoked paprika, 1/2 teaspoon of dried thyme, and a bay leaf. Bring the soup to a boil, then reduce the heat to a steady simmer.

Let the soup simmer, uncovered, for 20-25 minutes. The potatoes are done when they are fork-tender and easily break apart when pressed against the side of the pot.

Step 5 — Create a Creamy Texture

Once the potatoes are tender, use a potato masher or the back of a wooden spoon to gently mash some of the potatoes directly in the pot. This will release their starch and naturally thicken the soup, giving it a heartier, creamier consistency without needing heavy cream.

For an even richer texture, you can stir in 1/2 cup of half-and-half or whole milk at the very end of cooking. Heat through but do not boil once dairy is added.

Step 6 — Final Seasoning and Serving

Return the browned andouille sausage to the pot. Taste the soup and season with additional salt, black pepper, and Cajun seasoning if needed. For a bit of heat, a few dashes of hot sauce are a great addition.

Ladle the hot Fall-Inspired Hearty Cajun Potato Soup into bowls and garnish with sliced green onions and fresh parsley. Serve immediately with crusty bread for dipping.

• Dairy-Free Version: Coconut Milk — Substitute heavy cream with full-fat coconut milk for a rich, lactose-free creaminess that complements the Cajun spices.

Common Mistakes to Avoid

• Mistake: Overloading the spice blend too early. Fix: Bloom your Cajun seasoning in oil first to unlock its full flavor without bitterness.
• Mistake: Using waxy potatoes that won’t break down. Fix: Opt for starchy Russet or Yukon Gold potatoes to create a naturally creamy, hearty base.
• Mistake: Adding dairy directly to boiling soup. Fix: Temper cream or milk with a ladle of hot soup first to prevent curdling.
• Mistake: Skipping the holy trinity (onion, celery, bell pepper). Fix: Sauté these aromatics until soft to build an authentic, deep Cajun flavor foundation.
• Mistake: Underseasoning throughout the cooking process. Fix: Season in layers, tasting after each major addition, as potatoes absorb salt.
• Mistake: Boiling the soup aggressively after adding potatoes. Fix: Simmer gently to cook potatoes evenly without making them gluey.
• Mistake: Not using a quality stock. Fix: Use a rich chicken or vegetable stock instead of water for a more robust, fall-inspired depth.
• Mistake: Forgetting to garnish for texture. Fix: Top with crispy bacon, green onions, or a dash of hot sauce to contrast the creamy soup.

Storing Tips

• Fridge: Cool completely, then store in an airtight container for up to 4 days.
• Freezer: Portion into freezer-safe containers or bags, leaving headspace, and freeze for up to 3 months.
• Reheat: Thaw in the refrigerator if frozen. Warm gently on the stove, stirring occasionally, until it reaches an internal temperature of 165°F.

For the best texture, give this Fall-Inspired Hearty Cajun Potato Soup a good stir when reheating, as the potatoes may absorb some liquid while stored.
