What Is Cajun Fish Soup?
Cajun Fish Soup is a hearty and aromatic seafood-based soup rooted in Cajun culinary traditions, known for its bold spices, rich broths, and use of local ingredients. It typically features white flaky fish (like catfish, snapper, or cod), simmered with vegetables, tomatoes, and Cajun seasonings, all brought together in a robust broth that’s spicy, smoky, and utterly satisfying.
Unlike creamy chowders or light fish stews, Cajun Fish Soup is bold, rustic, and zesty, with a flavor that grabs your attention from the first bite.

🍲 How to Make Cajun Fish Soup – Step-by-Step
1. Sauté the Veggies
In a large pot or Dutch oven, heat olive oil over medium heat. Add onion, bell pepper, and celery—the classic Cajun “holy trinity.” Cook for 5–7 minutes, stirring often, until the vegetables are softened.
2. Add Garlic and Spices
Add minced garlic, thyme, smoked paprika, Cajun seasoning, and red pepper flakes. Stir constantly for 1–2 minutes until fragrant. This step blooms the spices and deepens the flavor base.
3. Deglaze and Simmer
Pour in the diced tomatoes (with juices), tomato paste, and broth. Add the bay leaf. Stir well to combine and bring the soup to a gentle boil. Reduce the heat and let it simmer for 15–20 minutes, allowing the flavors to meld.
4. Add the Fish
Carefully add the chunks of white fish to the pot. Simmer gently for another 7–10 minutes, or until the fish is opaque and flakes easily with a fork. Avoid stirring too vigorously so the fish stays in hearty chunks.
5. Season and Serve
Remove the bay leaf. Taste and adjust salt, pepper, or heat. Finish with a squeeze of lemon juice, a sprinkle of chopped parsley or green onions, and a dash of hot sauce if you like it fiery!
