Ingredients & Swaps
Andouille Sausage
This smoky, spicy sausage is a Cajun classic. If you don’t have it, swap in kielbasa or smoked bratwurst for a milder take.
Cajun Seasoning
Brings the heat and flavor! No mix? Combine paprika, cayenne, garlic powder, onion powder, salt, pepper, and a pinch of oregano.
Chicken Broth
Gives the soup body and depth. You can also use chicken stock—just adjust salt as needed.
Potatoes
Russet potatoes work beautifully, but Yukon gold or red potatoes are great too. Peel and cube them before adding to the pot.
Cheddar Cheese
Mild cheddar adds melty richness. For even more flavor, try sharp cheddar or pepper jack. You can also serve cheese on the side.
Heavy Cream
Adds silky creaminess to balance the heat. Substitute with half-and-half if you prefer something lighter.
How to Make Cajun Potato Soup
- Brown the Sausage
In a large pot over medium heat, cook the sliced andouille sausage in a bit of oil until browned. Remove and set aside. - Sauté the Vegetables
In the same pot, sauté onion, celery, and red bell pepper until softened. Stir in garlic and cook for another minute. - Build the Base
Add Cajun seasoning, salt, pepper, paprika, and cayenne. Pour in chicken broth and stir in cubed potatoes. Simmer until potatoes are fork-tender, about 20–25 minutes. - Add the Good Stuff
Return the sausage to the pot. Stir in heavy cream and shredded cheddar cheese. Let everything melt together for 5 more minutes. - Serve & Garnish
Ladle into bowls, sprinkle with fresh parsley, and serve warm with crusty bread or cornbread on the side.
Adjusting the Heat
This soup has a bold flavor with just the right amount of spice—but it’s easy to tweak. Want more heat? Add extra cayenne or use a spicier sausage. Prefer a milder soup? Use less Cajun seasoning and opt for a mild sausage.
