What You’ll Need
Here’s everything you need to make a big pot of creamy Cajun potato goodness:
Ingredients
- 1 tablespoon olive oil or butter
- 12 oz smoked sausage (andouille or kielbasa), sliced
- 1 medium onion, diced
- 1 bell pepper (any color), diced
- 2 celery stalks, chopped
- 3 cloves garlic, minced
- 2 pounds potatoes, peeled and diced (Yukon gold or russet)
- 4 cups chicken broth
- 1 1/2 cups milk or half-and-half
- 1 cup shredded cheddar cheese
- 1/2 teaspoon smoked paprika
- 2 teaspoons Cajun seasoning (more to taste)
- 1/2 teaspoon dried thyme
- Salt and black pepper, to taste
- 1/2 cup sour cream or Greek yogurt (optional, for creaminess)
- Chopped green onions and extra cheese, for topping
Step-by-Step Instructions
Step 1: Cook the Sausage
Heat olive oil or butter in a large soup pot or Dutch oven over medium heat.
Add the sliced smoked sausage and cook until browned and slightly crisp on the edges, about 5–6 minutes.
Remove the sausage with a slotted spoon and set aside, leaving the flavorful drippings in the pot.
Step 2: Sauté the Vegetables
To the same pot, add diced onion, bell pepper, and celery.
Cook for 4–5 minutes, stirring occasionally, until softened and aromatic.
Add the minced garlic and cook for another 30 seconds until fragrant.
Step 3: Add Potatoes and Broth
Stir in the diced potatoes, Cajun seasoning, smoked paprika, thyme, salt, and pepper.
Pour in the chicken broth and stir to combine.
Bring the mixture to a boil, then reduce heat to medium-low. Cover and simmer for about 15–20 minutes, or until the potatoes are tender when pierced with a fork.
Step 4: Mash for Creaminess
Once the potatoes are cooked, use a potato masher or the back of a spoon to mash some of the potatoes directly in the pot.
This gives the soup a naturally thick, creamy texture without adding flour.
If you prefer a smoother consistency, use an immersion blender to puree part of the soup while leaving some chunks for texture.
Step 5: Add Milk and Cheese
Stir in the milk (or half-and-half) and shredded cheddar cheese.
Stir gently until the cheese melts and the soup becomes creamy.
If you want extra richness, stir in sour cream or Greek yogurt at this point.
Step 6: Add Sausage Back
Return the cooked sausage to the pot and stir well.
Simmer uncovered for 5–10 more minutes, allowing the flavors to blend together.
Taste and adjust seasoning — add more Cajun spice if you like it hotter.
Step 7: Serve and Garnish
Ladle the soup into bowls and top with chopped green onions, shredded cheese, or a dollop of sour cream.
Serve hot with crusty bread, cornbread, or a simple side salad.
Tips for Perfect Cajun Potato Soup
- Choose the right potatoes.
Yukon gold potatoes give a buttery flavor and creamy texture, while russets make the soup thicker and heartier. - Adjust the spice level.
Start with 1–2 teaspoons of Cajun seasoning and add more to taste. Some blends are spicier than others. - Don’t skip browning the sausage.
It adds smoky flavor that deepens the soup’s taste. - Mash partially for best texture.
Blending too much can make the soup too smooth — a mix of creamy and chunky is perfect. - Add cheese slowly.
To prevent clumping, stir in cheese gradually over low heat. - Make it lighter.
Swap milk or cream for unsweetened almond milk or coconut milk for a dairy-free version.
Flavor Variations
This soup is wonderfully flexible — here are some delicious twists you can try:
Protein Variations
