Cajun Potato Soup is made with andouille sausage, potatoes, vegetables, and a blend of Cajun spices, enriched with heavy cream and cheddar cheese for a spicy, creamy, and comforting soup! It’s perfect for those looking to satisfy their taste buds with a zesty Cajun twist on a classic potato soup.

Ingredients & Substitutions
Andouille Sausage: Andouille is a spicy, smoked pork sausage that is often used in Cajun and Creole cuisine. It is usually precooked, so you just need to heat it up and brown it (if preferred) before adding it to recipes like this one. Kielbasa, smoked bratwurst, or another kind of smoked sausage can be used as a substitute. But, they may not have the same level of spiciness as Andouille.
Cajun Seasoning: If you don’t have any, make your own Cajun seasoning with seasonings you probably already have on hand! Salt, black pepper, paprika, and cayenne pepper are also added to the soup. For more of a kick, add more cayenne pepper and Cajun seasoning.
Chicken Broth: Chicken broth is the liquid base for the soup. You could substitute chicken stock, but you may want to adjust the amount of salt added.
Potatoes: I prefer russet potatoes in this soup for their texture and flavor-absorbing capabilities. However, you could substitute Yukon gold, red potatoes, or potatoes you have on hand. Peel and cube the potatoes before adding them to the soup.
Cheese: Mild cheddar cheese is added to the soup, melting to create a rich, cheesy undertone. If preferred, you could serve the soup with cheese on the side, letting guests add as much (or as little) as they prefer. Taste testers loved the soup both ways!

Is Cajun Potato Soup Spicy?
Cajun potato soup does have a kick to it, for sure. Cajun cuisine is characterized by the use of a variety of spices and seasonings that can impart heat and flavor to dishes. If you prefer a milder version, you can reduce the amount of spicy ingredients (Cajun seasoning, cayenne pepper, andouille sausage) or adjust the recipe to your taste.

Storing & Reheating Cajun Potato Soup
To store Cajun Potato Soup, first, let the soup come to room temperature. Next, store the soup in an airtight container. For easy-to-grab meals, store the soup in individual-sized portions. Store in the refrigerator for up to 3-4 days. Reheat the soup in the microwave or in a saucepan on the stovetop.

Can I Freeze Cajun Potato Soup?
Sure! For longer storage, freeze the soup. First, let the soup cool to room temperature. Next, store the soup in freezer-safe containers, leaving some space at the top for expansion. It will last in the freezer for up to 2-3 months. When ready to enjoy, let the soup thaw in the refrigerator before reheating.

Such a flavorful soup! I loved this, and the slight kick from the andouille, cajun seasoning, and cayenne is fantastic!

Annabelle
This is such an interesting soup! It has hearty potatoes, kielbasa, and veggies, along with a salty, spicy, light broth!

So good. The cajun flavor complements the sausage and potatoes nicely! The broth is creamy without feeling too heavy.

Selena
Lovely twist on a potato soup. I really liked the flavor the cajun seasoning brought and the cheese stirred in at the end makes it extra creamy and delicious.
Delicious!! Made it exactly as written. A keeper!!
Wowza! Good flavor but way too spicy! I measured exactly and our taste buds are burned! I’ll make it again without the cayenne pepper
I added kale, it was great!!
This soup was bomb! I loved how quickly it came together with ingredients most of us keep on hand. It was rich, creamy, comfort food which my family really appreciated during this latest cold snap. It will be put on repeat along with all our favorite cozy, winter meals. Great job, Girl!
I was confused by the cook time , I know potatoes are a little tricky but it definitely took way longer than 25 mins for them to be fork tender . and to simmer the whole time ? I thought I was mis reading the instructions but no , from medium heat to simmering for 25 minutes? definitely didn’t cook the potatoes
Were they peeled and cubed? They should definitely be fork tender at 25 minutes if they are cubed.
