Ingredients List

• 4 medium russet potatoes, peeled and diced
• 1 lb smoked sausage or andouille, sliced
• 3 tbsp butter
• 1 small onion, finely chopped
• 2 celery stalks, diced
• 1 small bell pepper, diced
• 3 cloves garlic, minced
• 3 tbsp all-purpose flour
• 4 cups chicken broth
• 1 cup heavy cream
• 1 cup shredded cheddar cheese
• 1 tsp Cajun seasoning (adjust to taste)
• 1/2 tsp smoked paprika
• Salt and black pepper to taste
• 2 green onions, sliced
• Fresh parsley for garnish

Step-by-Step Instructions

Step 1: Build the flavor base

Melt butter in a large heavy-bottomed pot over medium heat. Add onion, celery, and bell pepper. Sauté until softened and aromatic, about 5 minutes. Stir in garlic and cook briefly until fragrant.

Step 2: Brown the sausage

Add sliced smoked sausage to the pot and cook until lightly browned. This step releases flavorful oils that enrich the entire soup.

Step 3: Create the roux

Sprinkle flour over the mixture and stir continuously for 1–2 minutes to cook out the raw flour taste. This forms a light roux that will give the soup body and structure.

Step 4: Add liquids and potatoes

Gradually pour in chicken broth while stirring to prevent lumps. Add diced potatoes, Cajun seasoning, smoked paprika, salt, and pepper. Bring to a gentle boil, then reduce to a simmer.

Step 5: Simmer until tender

Cover and cook for 15–20 minutes, stirring occasionally, until potatoes are fork-tender and the broth has thickened slightly.

Step 6: Finish with cream and cheese

Lower heat and stir in heavy cream and shredded cheddar. Allow cheese to melt fully, creating a rich, velvety texture. Taste and adjust seasoning.

Step 7: Garnish and serve

Ladle into bowls and finish with green onions and fresh parsley. Serve hot for the best flavor and consistency.

FAQs

Can I make Cajun potato soup vegetarian?
