🥔 What is Cajun potato soup?

Cajun Potato Soup is a creamy, spicy, and savory soup that highlights the flavors of the American South. It typically features andouille sausage, russet potatoes, and the Cajun “holy trinity” — onion, bell pepper, and celery — cooked down in a rich broth seasoned with Cajun spices.

What makes this soup “Cajun” is its bold seasoning. It combines paprika, cayenne pepper, black pepper, and garlic, forming a deep flavor profile that’s spicy yet comforting. These spices are fundamental in traditional Cajun dishes, which are known for their intensity and complexity.

Unlike chowders or typical potato soups, Cajun Potato Soup has a smoky, spicy punch thanks to sausage and seasoning. With the addition of heavy cream and cheddar cheese, it becomes creamy, filling, and incredibly satisfying. You’ll find this dish perfect for cold nights, quick weekday meals, or anytime you need comfort in a bowl.

🧄 Key ingredients and their roles

A successful Cajun Potato Soup relies on both quality ingredients and how they come together. Each component plays an important role in shaping the flavor and texture of the soup.

🔥 Sausage (andouille sausage)

• Main ingredient: 1 ring (13.5 oz) andouille sausage, sliced into ¼-inch rounds

• Andouille sausage adds smoky, spicy richness that defines Cajun flavor.

• You can substitute with turkey or chicken sausage for a lighter option.

Andouille is a staple in Cajun cuisine, known for its bold flavor and coarse texture. When sautéed in oil, it caramelizes beautifully, infusing the soup with layers of flavor.

🧅 Vegetables: The holy trinity of Cajun cooking

• 1 large onion (about 1 cup)

• ½ cup diced celery (1 rib)

• ½ red bell pepper, diced

These three vegetables form the aromatic foundation of many Louisiana dishes. Known as the “holy trinity,” this mix is key in creating authentic Cajun flavor.

You can explore the flavor profiles of bell pepper and how they interact with other veggies in savory dishes. Sautéing them slowly brings out their natural sweetness and balances the spice in the soup.

🥔 Potatoes: The heart of the soup

• 4 large russet potatoes, peeled and cubed

Russet potatoes are ideal because they break down easily during cooking, adding a natural creaminess to the broth. These potatoes not only bulk up the soup but help thicken it organically.

🌶️ Cajun seasoning and spices

• 1 teaspoon Cajun seasoning

• ½ teaspoon kosher salt

• ½ teaspoon black pepper

• ½ teaspoon paprika

• ¼ teaspoon cayenne pepper

These spices are the backbone of Cajun flavor. Paprika and cayenne pepper provide heat and smokiness, while garlic and black pepper build flavor complexity. Homemade blends can be customized, but quality store-bought mixes work well too.

You can explore the origins of paprika and its role in spice blends to better understand its culinary power.

🧀 Broth, cream, and cheese

• 4 cups (960g) chicken broth

• ½ cup (119g) heavy whipping cream

• 1 cup (113g) shredded mild cheddar cheese

Chicken broth forms the soup’s liquid base, while heavy cream and cheddar cheese give it a rich, creamy texture. Avoid boiling after adding cream to prevent curdling.

🌿 Garnish

• Chopped parsley

Fresh parsley not only adds color but a mild herbal note that balances richness. You can read more about the benefits of fresh parsley garnish in finishing dishes.

🍲 Equipment needed

To prepare this hearty soup, you’ll need:

• Large heavy-bottomed pot

• Cutting board and chef’s knife

• Wooden spoon or silicone spatula

• Measuring cups and spoons

• Ladle

• Potato masher (optional for thicker texture)

Optional: An immersion blender for a smoother finish, although this is best used lightly to keep the soup chunky.

2. Stir to coat everything evenly.

3. Pour in 4 cups of chicken broth and add the cubed potatoes.

4. Reduce the heat to low and let it simmer for 20–25 minutes, or until potatoes are fork-tender.

Stir occasionally and check for seasoning balance as the soup develops its flavor.

🧀 Finish with cream and cheese

1. Return the cooked sausage to the pot.

2. Add ½ cup heavy cream and 1 cup shredded mild cheddar cheese.

3. Stir until cheese is melted and the soup is creamy.

4. Simmer for an additional 5 minutes.

• Balance the heat: If you’re sensitive to spice, reduce or omit cayenne. You can always add hot sauce later.

• Prep ahead: Dice vegetables the night before or cook sausage in advance.

• Meal prep friendly: Store in individual containers for easy grab-and-go meals.
