Fish Creole Recipe: Spicy Tomato Braised Seafood Delight

This spicy tomato-braised seafood dish brings bold Creole flavors to your dinner table with minimal effort. The combination of ripe tomatoes, bell peppers, and aromatic spices creates a rich, complex base that perfectly complements tender fish.

I developed this recipe to capture the essence of New Orleans cooking without complicated techniques. The fish cooks gently in the sauce, absorbing all the vibrant flavors while staying moist and flaky. It’s a one-pan meal that comes together in under 45 minutes.

What emerges is a colorful, fragrant dish that’s equally suited for weeknight dinners or special occasions. The sauce develops deep, layered flavors as it simmers, while the fish adds a delicate texture that soaks up every bit of the spicy tomato broth.

Serve it over rice to catch every drop of the delicious sauce. This creation will transport your taste buds straight to the heart of Louisiana.

Ingredients for Fish Creole*

Bold Creole flavors start with fresh fish and a handful of pantry staples.

The fish is the star here. Cod or halibut hold up best to the braising (avoid delicate flaky varieties like tilapia). Fresh fillets from the seafood counter are ideal, but frozen works too—just thaw completely first. For the peppers, I grab whatever’s on sale at Whole Foods or my local market. Look for firm, glossy skins (wrinkled ones are past their prime). The Cajun seasoning? Tony Chachere’s is the gold standard.

No Cajun seasoning? Mix 1 tsp each paprika, garlic powder, onion powder, plus half a tsp cayenne. Fresh tomatoes can replace canned in summer (about 4 large, peeled and diced). Short on bell peppers? Use poblano for a milder heat. The hot sauce is flexible—Crystal or Tabasco are classic, but any vinegar-based one works. Don’t skip the tomato paste though; it’s what deepens the sauce.

The sauce actually improves overnight—2-3 days in the fridge is perfect. Freezes beautifully for up to 3 months (just leave out the fish and add it fresh when reheating). I always double the sauce portion; it’s that good over rice or with crusty bread.

Step-by-Step Instructions for Fish Creole

Here’s the straightforward method that delivers bold, spicy flavor in every bite.

Step 1: Build the Flavor Base

Heat the 3 tbsp olive oil in a large, deep skillet over medium heat. Add the finely diced yellow onion, green bell pepper, and red bell pepper along with the 2 pieces celery stalks.

Cook for 6-8 minutes until the vegetables soften and the onion becomes translucent. Stir occasionally to prevent browning. This “holy trinity” of vegetables forms the aromatic foundation of the dish, so take your time here.

Step 2: Develop the Sauce

Stir in the 4 cloves garlic cloves and cook for 30 seconds until fragrant. Then add the 2 tbsp tomato paste, 1 tbsp Cajun seasoning, 1 tsp dried thyme, and 1 tsp dried oregano.

Cook for 1-2 minutes, stirring constantly, until the tomato paste darkens slightly. This step builds depth in the sauce. Pour in the 2 cups canned diced tomatoes (with juices), add the 1 whole bay leaf, and bring to a gentle simmer.

Step 3: Poach the Fish Fillets

Season the 1.5 lb white fish fillets with the 1 tsp salt and 0.5 tsp black pepper. Gently place them into the simmering sauce. The fillets should be mostly submerged.

Cover and cook for 8-10 minutes until the fish flakes easily with a fork and reaches 145°F internally. Avoid stirring once the fish is in the pan to prevent it from breaking apart.

Step 4: Finish and Serve

Remove the skillet from heat. Discard the bay leaf, then gently stir in the 1 tsp hot sauce. Taste and adjust seasoning if needed.

Let the dish sit for 2-3 minutes to allow the flavors to meld. The sauce will thicken slightly as it cools. Serve the fish and sauce over rice, making sure each portion gets plenty of the rich, tomato-based sauce.

Storing and Reheating Leftovers

Refrigerator Storage

Let this creation cool for no more than 2 hours before transferring to airtight containers. Store in the fridge at 40°F or below for up to 3 days. The flavors meld beautifully overnight, making leftovers even more delicious. ❄️

Freezer Storage

For longer storage, freeze the sauce separately from the fish. Use quart-sized freezer bags and leave 1 inch of headspace. The sauce freezes well for up to 3 months. I recommend labeling with the date to keep track of freshness.

Stovetop Reheating

Reheat the sauce in a skillet over medium-low heat for 8-10 minutes, stirring occasionally. Add the fish during the last 5 minutes to warm through. Sprinkle with 1-2 tsp water if the sauce thickens too much. 🔥

Microwave Reheating

Place individual portions in a microwave-safe dish, cover with a damp paper towel, and heat on 70% power for 2-3 minutes. Stir halfway through. Ensure the internal temperature reaches 145°F before serving.

Make-Ahead Tip

Prepare the sauce a day in advance and store it in the fridge. When ready to serve, reheat the sauce and poach fresh fish fillets in it for 8-10 minutes. This ensures the fish stays tender and doesn’t overcook during storage.
