🥣 What Is Cajun Potato Soup?

This creamy Cajun-style soup takes classic potato soup up a notch with bold spices and savory smoked sausage. Each spoonful is packed with robust flavor thanks to a base of onion, celery, bell pepper, and garlic—also known as the “Cajun trinity.” Add in creamy potatoes, a touch of heat from Cajun seasoning and cayenne, and the richness of cheddar cheese, and you’ve got a soul-warming dish that’s full of Southern charm.

🛒 Ingredients & Substitutions

Here’s what you’ll need to make this spicy potato soup, along with some easy substitutions:

  • Andouille Sausage: This spicy, smoked sausage brings authentic Cajun flavor. Substitute with kielbasa, smoked bratwurst, or another precooked smoked sausage if needed—just note the spice level may be lower.
  • Cajun Seasoning: Use your favorite store-bought blend or mix your own with paprika, cayenne, garlic powder, onion powder, thyme, and oregano. Adjust to taste if you want it spicier or milder.
  • Chicken Broth: This forms the soup base. You can also use chicken stock or a low-sodium broth and adjust seasoning accordingly.
  • Potatoes: Russet potatoes work best for their soft, fluffy texture, but Yukon gold or red potatoes are great options too. Peel and cube before adding.
  • Vegetables: Onion, celery, red bell pepper, and garlic create a flavorful foundation.
  • Cheddar Cheese: Mild cheddar melts beautifully into the soup. Feel free to swap with sharp cheddar or serve it on the side for guests to add themselves.
  • Heavy Cream: Adds creaminess. You can use half-and-half or whole milk in a pinch, though the result may be slightly less rich.

🔥 Is Cajun Potato Soup Spicy?

It does have a noticeable kick! Cajun cuisine is known for bold flavors, and this soup is no exception. You can easily tone it down by using less Cajun seasoning, cayenne pepper, or opting for a milder sausage. Or, if you’re a heat lover, turn it up!

🧑‍🍳 How to Make Cajun Potato Soup

Step-by-step instructions:

  1. Cook the Sausage:
    In a large pot, heat the oil over medium heat. Add the andouille sausage and brown for about 3–4 minutes. Remove and set aside.
  2. Sauté the Vegetables:
    In the same pot, add onion, celery, and red bell pepper. Cook until softened, about 5–8 minutes. Add minced garlic and cook for another minute.
  3. Build the Soup:
    Stir in Cajun seasoning, salt, pepper, paprika, and cayenne. Add chicken broth and potatoes. Simmer for 20–25 minutes until potatoes are fork-tender.
  4. Finish with Cream & Cheese:
    Return sausage to the pot. Stir in the heavy cream and shredded cheddar cheese. Simmer for another 5 minutes until creamy and fully heated.
  5. Garnish & Serve:
    Sprinkle with chopped parsley and serve warm with crusty bread.
