FAQs

What type of fish works best in Cajun Fish Soup?

Firm white fish like cod, catfish, tilapia, or haddock work best because they hold up well during simmering.

Is this soup very spicy?

It has a mild to medium heat level, but you can easily adjust the spiciness with more or less Cajun seasoning or cayenne pepper.

Can I use frozen fish?

Yes, just thaw it completely and pat dry before adding it to the soup to prevent excess water and ensure proper texture.

What can I serve with Cajun Fish Soup?

Crusty bread, rice, or cornbread are all excellent for soaking up the flavorful broth.

Can I make this soup ahead of time?

Yes. You can make the soup base ahead of time, but for best results, add the fish just before serving to avoid overcooking.

You can simmer it uncovered for a bit longer or stir in a cornstarch slurry if you prefer a thicker consistency.
