• 4 cups low-sodium chicken broth or vegetable broth – Creates a flavorful soup base.
• 1 cup heavy cream or half-and-half – Gives the soup its rich, silky finish.
• 2 tablespoons all-purpose flour (optional) – Helps create an even thicker, creamier consistency.
• 1 tablespoon Cajun seasoning – Adds signature smoky heat and Southern flavor.
• 1 tablespoon butter or neutral oil – Used to brown the sausage and sauté the vegetables.

Step-by-Step Instructions

Step 1: Prepare the Ingredients

Peel and dice the Russet and Yukon Gold potatoes into even 1-inch cubes. Dice the onion, celery, and green bell pepper, mince the garlic, and slice the beef sausage into ¼-inch rounds.

Step 2: Brown the Sausage

Heat the butter or oil in a large Dutch oven over medium-high heat. Add the sliced sausage and cook for 5–7 minutes, turning occasionally until browned and slightly crisp. Remove the sausage and set aside, leaving the flavorful drippings in the pot.

Step 3: Sauté the Vegetables

Reduce the heat to medium and add the onion, celery, and green bell pepper. Cook for 8–10 minutes, stirring occasionally until softened and fragrant.

Step 4: Add Garlic and Seasoning

Stir in the minced garlic and Cajun seasoning. Cook for about 1 minute, stirring constantly until fragrant.

Step 5: Create a Thick Base (Optional)

For a thicker soup, sprinkle the flour over the vegetables and cook for 1–2 minutes, stirring continuously to create a light roux.

Step 6: Add Broth and Potatoes

Gradually pour in the chicken broth while whisking to prevent lumps. Add both types of diced potatoes, bring the soup to a gentle simmer, cover, and cook for 15–20 minutes, or until the potatoes are fork-tender.

Step 7: Blend for Creaminess

Mash some of the cooked potatoes with a potato masher for a chunky soup, or use an immersion blender to partially blend until you reach your preferred consistency.

Step 8: Finish the Soup

Reduce the heat to low and stir in the heavy cream along with the browned sausage. Heat gently until warmed through without boiling.

Step 9: Taste and Adjust

Taste the soup and adjust with additional Cajun seasoning, salt, or black pepper as needed.

Step 10: Garnish and Serve

Ladle the soup into bowls and top with chopped green onions, shredded cheddar cheese, sour cream, and a few dashes of hot sauce if desired.

Recipe Notes & Tips

• Brown the Sausage Well – The caramelized bits left in the pot add tremendous flavor to the broth.
• Use Two Potato Varieties – Russets create creaminess while Yukon Gold potatoes maintain texture.
• Avoid Boiling After Adding Cream – Gentle heat prevents the dairy from separating.
• Control the Heat – Start with less Cajun seasoning and add more to taste.
• Partially Mash the Potatoes – This creates a naturally thick soup without needing excessive flour.
• Taste Before Serving – Sausage and Cajun seasoning vary in saltiness, so adjust seasoning at the end.

Why This Recipe Works

This Cajun Potato Soup builds layers of flavor by first browning the sausage, allowing its smoky richness to infuse the cooking pot before the vegetables are sautéed. Using both Russet and Yukon Gold potatoes creates the perfect combination of creamy texture and hearty bites, while Cajun seasoning, garlic, and the classic “Holy Trinity” of onion, celery, and bell pepper provide authentic Southern flavor. A touch of heavy cream rounds out the broth, creating a silky finish that balances the spices without dulling them. At approximately 450 calories per serving, this soup delivers a satisfying balance of protein, vegetables, and comforting creaminess that’s hearty enough to serve as a complete meal.

Cajun Potato Soup is a comforting, flavor-packed recipe that transforms simple pantry ingredients into a rich and satisfying Southern-inspired meal. Whether you’re making it for a cozy family dinner, preparing meals for the week, or serving guests on a chilly evening, this soup is guaranteed to impress. For a lighter version, substitute half-and-half for the heavy cream and use turkey sausage while still enjoying the same bold Cajun flavors and creamy texture.
