Cajun Potato Soup is a rich, comforting, and slightly spicy soup that I love to make when I want a cozy, one-pot meal with bold Southern flavor. With creamy potatoes, aromatic veggies, Cajun spices, and a smoky kick from paprika.

I love how this soup turns humble ingredients into something crave-worthy and filling. Even without meat, it’s hearty, flavorful, and satisfying.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Russet or Yukon gold potatoes, peeled and diced
Onion, chopped
Celery, chopped
Bell pepper, diced (optional, for extra flavor)
Garlic, minced
Olive oil or butter
All-purpose flour
Vegetable broth
Heavy cream or half-and-half (or coconut milk for dairy-free)
Cajun seasoning
Smoked paprika
Salt and black pepper
Fresh lemon juice (just a splash to brighten)
Optional toppings: shredded cheese, green onions, hot sauce, plant-based sausage

Directions

I heat olive oil or butter in a large pot over medium heat. I sauté the onion, celery, and bell pepper (if using) until softened, about 5–6 minutes.
I stir in the garlic and cook for another minute until fragrant.
I add the flour and cook for 1–2 minutes, stirring constantly, to create a light roux.
I slowly pour in the vegetable broth, whisking to avoid lumps.
I add the diced potatoes, Cajun seasoning, smoked paprika, salt, and pepper. I bring the soup to a boil, then reduce the heat and simmer for 15–20 minutes, or until the potatoes are tender.
I stir in the cream (or dairy-free alternative) and lightly mash some of the potatoes with a potato masher to thicken the soup while leaving chunks for texture.
I finish with a splash of lemon juice, taste, and adjust seasoning if needed.
I ladle the soup into bowls and top with shredded cheese, green onions, or a drizzle of hot sauce if I want extra kick.

Servings and timing

This recipe makes about 6 servings and takes around 10 minutes of prep time and 30 minutes of cook time, for a total of 40 minutes.

Variations

I sometimes add corn or canned white beans for more texture and body. If I’m looking for extra protein, I stir in sliced plant-based sausage. For a smoky depth, I up the smoked paprika or even add a drop of liquid smoke. When I want it extra thick, I blend a cup of the soup and stir it back in.

storage/reheating

I store leftovers in the fridge for up to 4 days in an airtight container. To reheat, I warm it on the stovetop over medium-low heat, adding a splash of broth or water if it thickens too much. It reheats well in the microwave, too. I avoid freezing it if I’ve used dairy, but it freezes well if I use coconut milk instead.

FAQs

Can I make it dairy-free?

Yes. I replace the cream with full-fat coconut milk or any unsweetened plant-based milk plus a little cornstarch to thicken.

Is it spicy?

The spice level depends on the Cajun seasoning. I start with a little and add more to taste. For extra heat, I add cayenne or hot sauce.

Can I blend the soup for a smooth texture?

Yes, I blend some or all of the soup if I want a creamier result. I prefer keeping some chunks of potato for texture.

What kind of potatoes should I use?

I like Yukon gold for a creamy texture or russet potatoes for a heartier bite. Both work well.

What should I serve with it?

I usually serve it with crusty bread, cornbread, or a simple green salad to balance the richness of the soup.

Conclusion

This Cajun Potato Soup is rich, spicy, and satisfying—even without any meat. It’s the perfect comfort food with a kick, and I love how easy it is to make with simple pantry ingredients. Whether I keep it classic or add in extra veggies or plant-based sausage, this soup always delivers bold flavor in every bowl.
