Ingredients You’ll Need

Here’s what makes this Cajun fish soup sing:

• White Fish Fillets: Choose firm varieties like cod, halibut, or tilapia—they hold up well in the soup without falling apart.
• Cajun Seasoning: The heart of the flavor. Go store-bought or mix your own with paprika, cayenne, garlic powder, and thyme.
• Onion and Celery: Classic aromatics that build the soup’s savory base.
• Bell Peppers: Red or green work fine. They add a sweet crunch and a burst of color.
• Garlic: Because Cajun food without garlic just isn’t right.
• Diced Tomatoes: Adds depth, acidity, and a rich tomato base.
• Fish or Chicken Broth: Either works. Fish broth enhances the seafood flavor, but chicken broth gives a mellow background.
• Potatoes: A starchy addition that makes the soup feel extra hearty.
• Bay Leaves: For a subtle layer of earthy flavor.
• Hot Sauce: Optional, but highly recommended if you love a fiery finish.
• Parsley or Green Onions: For a fresh pop right before serving.

Variations

• Seafood Medley: Toss in some shrimp or scallops along with the fish for a fuller seafood experience.
• Add Rice or Quinoa: For a thicker, more filling bowl.
• Creamy Twist: Stir in a splash of coconut milk or heavy cream for a creamier version.
• Vegetarian Option: Swap the fish for firm tofu and use veggie broth. It still picks up the Cajun flavors beautifully.
• Spice Control: Adjust the heat by dialing up or down the cayenne or hot sauce.

How to Make Zesty Cajun Fish Soup

Step 1: Sauté the Aromatics

In a large pot, heat some oil over medium heat. Add diced onion, celery, and bell pepper. Sauté until softened and aromatic—about 5 minutes.

Step 2: Build the Flavor Base

Stir in the minced garlic and Cajun seasoning. Let it toast for a minute to release the spices’ oils and deepen the flavor.

Step 3: Add Tomatoes and Broth

Pour in the diced tomatoes (with juice) and your broth of choice. Toss in the bay leaves and bring the mixture to a simmer.

Step 4: Cook the Potatoes

Add chopped potatoes to the pot and simmer until they’re fork-tender, about 12–15 minutes.

Step 5: Add the Fish

Gently add your chunks of fish. Simmer for another 6–8 minutes, just until the fish is opaque and flakes easily.

Step 6: Taste and Finish

Remove bay leaves, adjust seasoning with salt, pepper, or more Cajun spice if desired. Add a few dashes of hot sauce if you like it spicy.

Step 7: Garnish and Serve

Ladle into bowls and top with chopped parsley or green onions for a fresh finish.

Pro Tips for Making the Recipe

• Don’t Overcook the Fish: Add it at the end so it stays tender and doesn’t fall apart.
• Use a Good Cajun Seasoning: If yours is too salty or bland, it can throw off the whole soup. Taste and adjust.
• Prep Ahead: Chop your veggies and measure spices before you start. It makes the cooking process seamless.
• Simmer Gently: Keep the heat moderate when adding fish—boiling will make it tough.

How to Serve

This soup is bold enough to stand alone but even better with some accompaniments:

Crusty Bread:

A slice of warm baguette or cornbread is perfect for soaking up every drop of broth.

Rice or Grits:

Serve the soup over a scoop of cooked white rice or creamy grits for a Southern-inspired twist.

Side Salad:

Balance the spice with a fresh green salad dressed in lemon or vinaigrette.

Garnishes:

Don’t skip the parsley or green onion—it adds color and a pop of fresh flavor. A lemon wedge on the side is also a great touch.

Make Ahead and Storage

Storing Leftovers

Cool completely and store in an airtight container in the fridge for up to 3 days.

Freezing

This soup freezes beautifully—just be aware that the texture of the fish may change slightly. Freeze in individual portions for easy lunches.

Reheating

Reheat gently on the stove over medium-low heat. If microwaving, use a lower power setting and stir often to avoid overcooking the fish.

FAQs

Can I use frozen fish for this recipe?
Yes, absolutely. Just make sure it’s fully thawed and patted dry before adding to the soup to avoid extra water thinning out the broth.

Is Cajun seasoning really spicy?
It can be! Many blends include cayenne pepper. Taste your mix first and reduce the amount if you’re sensitive to heat. You can always add more later.

What if I don’t have fish broth?
No problem. Chicken broth is a great substitute and still gives you a well-rounded flavor. Vegetable broth works in a pinch too.

Can I make this in a slow cooker?
Sort of. You can cook the base (veggies, potatoes, broth, and seasoning) on low for 4–5 hours, then add the fish during the last 30 minutes to avoid overcooking.
