Cajun Potato Soup is a hearty and comforting bowl that combines tender potatoes, smoky Cajun spices, and a creamy broth. It’s got just the right amount of kick to warm you up on chilly days, with flavors that are bold but never overwhelming. The potato chunks give it a nice bite, while the seasoning adds a little fun heat that makes every spoonful satisfying.
I love making this soup when I want something that feels cozy but still exciting. The Cajun spices remind me of weekends spent cooking with friends and sharing meals that bring everyone together. One tip I have is to use a good smoked paprika or Cajun seasoning blend to really bring out those smoky, spicy notes that make this soup special.
When I serve this soup, I like to add a dollop of sour cream and a sprinkle of chopped green onions on top—it adds a cool contrast that complements the spice perfectly. It’s great for a simple family dinner or as an easy dish to bring to a potluck. Honestly, once you try this soup, it’s hard not to make it again and again!
Key Ingredients & Substitutions
Potatoes: I like using Yukon Gold for their creamy texture, but Russets are a good alternative if you prefer a fluffier soup.
Sausage: Andouille adds smoky heat, but you can swap with kielbasa or chicken sausage for less spice.
Cajun Seasoning: This is the heart of the flavor. If you don’t have a mix, combine paprika, garlic powder, cayenne, and oregano to make your own.
Chicken Broth: Vegetable broth works well if you want a vegetarian version. Just skip the sausage or use a plant-based alternative.
Heavy Cream: Half-and-half or coconut milk can be used for a lighter or dairy-free option, altering the richness slightly.
How Can You Get the Perfect Soup Texture?
Balancing smooth and chunky potato pieces is key. Here’s how I do it:
- Cook potatoes until very tender so they blend smoothly.
- Use an immersion blender to puree about half the soup directly in the pot.
- Leave some potato chunks whole for texture and bite.
- If you don’t have an immersion blender, carefully blend half in a regular blender, then mix it back in.
- Stir in cream last to keep the soup rich and silky without curdling.
This method creates a creamy yet hearty soup that feels just right with every spoonful.
Equipment You’ll Need
- Large heavy-bottomed pot – I use this to evenly cook the soup and prevent burning.
- Wooden spoon or spatula – perfect for stirring the spices and veggies without scratching the pot.
- Immersion blender or regular blender – for blending part of the soup to get that smooth, creamy texture.
- Measuring spoons and cups – to get your seasonings just right.
- Knife and chopping board – for dicing potatoes, peppers, and onions efficiently.
Flavor Variations & Add-Ins
- Use kielbasa or chicken sausage instead of andouille for a milder flavor.
- Mix in corn or diced tomatoes for added sweetness and a touch of acidity.
- Spice it up with more cayenne or hot sauce if you love extra heat.
- Add a splash of smoked paprika or chipotle peppers for a smoky twist.

- 1 medium onion, finely chopped
- 1 red bell pepper, diced
- 2 cloves garlic, minced

Time Needed
This soup takes about 10 minutes to prep and 30 minutes to cook, making a total of roughly 40 minutes from start to finish. It’s a quick and easy meal perfect for any day.
Step-by-Step Instructions:
1. Sauté the Vegetables and Sausage:
Heat the olive oil or butter in a large pot over medium heat. Add the chopped onion and diced red bell pepper. Cook for about 5 minutes until softened. Then add the minced garlic and sliced sausage. Stir and cook for another 3 to 5 minutes until the sausage is lightly browned.
2. Add Potatoes and Seasonings:
Mix in the diced potatoes, Cajun seasoning, smoked paprika, dried thyme, cayenne pepper, salt, and black pepper. Cook this mixture for about 2 minutes, stirring occasionally, so the spices get toasted and flavorful.
3. Cook the Soup:
Pour in chicken broth enough to cover the potatoes (about 4 cups). Bring to a boil, then turn the heat down to a simmer. Cover the pot and let it cook for about 20 minutes, or until the potatoes are very tender.
4. Blend and Add Cream:
Use an immersion blender to carefully blend the soup until it’s mostly smooth but still has some chunks for texture. If you don’t have an immersion blender, blend half the soup in a regular blender, then pour it back into the pot. Stir in the heavy cream and warm the soup gently without boiling.
5. Serve and Garnish:
Ladle the hot soup into bowls. Sprinkle chopped green onions on top and add diced red bell pepper or a pinch of smoked paprika if you’d like extra color and flavor. Enjoy your creamy and spicy Cajun potato soup!
Can I Use Frozen Potatoes for This Soup?
Yes, you can use frozen diced potatoes if you’re short on time. Be sure to thaw them first and drain any excess water to avoid making the soup too watery.
How Can I Make This Soup Vegetarian?
Simply swap the chicken broth for vegetable broth and omit the sausage or replace it with a plant-based sausage alternative. The Cajun seasoning will still give it great flavor.
Can I Prep This Soup Ahead of Time?
Absolutely! You can chop vegetables and measure spices in advance. The soup can be cooked and then refrigerated for up to 3 days. Reheat gently on the stove to avoid curdling the cream.
How Spicy Is This Soup, and Can I Adjust It?
The spice level is moderate thanks to the Cajun seasoning and optional cayenne pepper — feel free to add more or reduce the cayenne based on your heat preference!
