Baked Redfish Recipe: Flaky White Fish With Cajun Kick

This baked redfish delivers the flaky, tender texture that defines perfectly cooked white fish. A simple yet bold Cajun seasoning blend brings depth without overpowering the natural sweetness of the fish.

The technique is straightforward: high heat ensures a quick cook time while maintaining moisture. The seasoning forms a light crust that locks in flavor, creating a dish that feels special with minimal effort.

What emerges from the oven is restaurant-quality fish with a golden exterior and meat that separates effortlessly with a fork. The Cajun kick adds just enough warmth to elevate the dish without overwhelming it.

Pair it with rice or roasted vegetables for a complete meal. This method guarantees consistent, impressive results every time.

Ingredients for Baked Redfish

Fresh redfish and bold Cajun spices create a restaurant-worthy dish with minimal effort.

The redfish is the star here. Whole Foods or local seafood markets often carry it fresh—look for fillets with a bright, translucent appearance (not dull or discolored). Skin-on adds texture, but skinless works if that’s what’s available. Wild-caught Gulf redfish is ideal if you can source it. The Cajun seasoning should be vibrant in color and aromatic—if it smells flat, it’s past its prime.

No Cajun blend on hand? Mix 1 tbsp paprika, 1 tsp each garlic powder, onion powder, and oregano, plus half the amount of cayenne for your own. Fresh out of lemon? Lime juice works in a pinch. For a milder kick, reduce the cayenne or omit it entirely. The butter can be swapped for more olive oil, but it adds a richness that complements the fish beautifully.

Redfish is best cooked the day you buy it, but it will keep in the fridge for 1-2 days if stored properly. Wrap it tightly in plastic or place it in a sealed container with a paper towel to absorb moisture. Leftover cooked fish reheats gently—2-3 days in the fridge, though it’s best enjoyed fresh.

Step-by-Step Instructions for Baked Redfish

Master this simple baking technique to achieve perfectly flaky, moist fillets with bold Cajun flavor every time.

Step 1: Season the Redfish with Cajun Spice Blend

Pat the 1.5 lb redfish fillets completely dry with paper towels. This critical step ensures the seasoning adheres properly and promotes even browning. I always use a clean kitchen towel for this to avoid paper fibers sticking to the fish.

In a small bowl, combine the 2 tbsp Cajun seasoning, 1 tsp paprika, 1 tsp dried thyme, 1 tsp dried oregano, 0.25 tsp cayenne pepper, 1 tsp kosher salt, and 0.5 tsp freshly ground black pepper. Rub this mixture evenly over all surfaces of the fillets, pressing gently to create a uniform crust. The fish should be fully coated with no bare spots.

Step 2: Sear and Aromatize for Depth of Flavor

Heat 2 tbsp olive oil in a large oven-safe skillet over medium-high heat. When the oil shimmers, add the seasoned fillets skin-side down if using skin-on. Sear for 2-3 minutes until the edges turn opaque and the seasoning begins to caramelize.

Add the 3 cloves minced garlic cloves and remaining 1 tbsp olive oil to the skillet. The garlic should sizzle immediately—cook for 30 seconds just until fragrant but not browned. Pour in the 2 tbsp unsalted butter and let it melt, then baste the fillets with the aromatic oil for 1 minute to build flavor layers.

Step 3: Bake to Flaky Perfection

Preheat your oven to 400°F. Transfer the skillet to the oven and bake for 10-12 minutes, depending on thickness. The fillets are done when they reach an internal temperature of 145°F and flake easily with a fork. I start checking at 8 minutes to prevent overcooking.

During the final 2 minutes of baking, squeeze the juice from 1 whole lemon over the fillets. The acid brightens the Cajun spices and cuts through the richness of the butter. Watch for the flesh to turn from translucent to opaque throughout.

Step 4: Garnish and Serve Immediately

Remove the skillet from the oven and transfer the fillets to a serving platter. Pour any pan juices over the top. Garnish with 0.25 cup chopped fresh parsley and a sprinkle of lemon zest from the same lemon for a pop of color and freshness.

Serve immediately while hot—the texture is best right out of the oven when the fillets are at their most tender and flaky. The fish should separate into clean, moist layers with the slightest pressure from a fork, with a golden, spice-crusted exterior that delivers that signature Cajun kick in every bite.

Essential Equipment for Great baked redfish

Oven-Safe Skillet

An oven-safe skillet is non-negotiable for this recipe. I swear by my 12-inch Lodge cast iron—it goes from stovetop searing to oven baking seamlessly. If you prefer non-stick, Calphalon’s hard-anodized works well too. Avoid thin aluminum pans.

Instant-Read Thermometer

Precise temperature reading prevents overcooking. My ThermoWorks Thermapen gives accurate readings in 3 seconds. Aim for 145°F internal temp in the thickest part. Without this, you risk dry fish or undercooked centers. 🌡️

Quality Basting Spoon

A heat-resistant silicone basting spoon helps coat the fillets with that flavorful garlic butter. I use OXO’s 12-inch version. The long handle keeps your hand safe while the flexible head scoops up every bit of liquid.

Citrus Zester

For that final garnish, a Microplane zester creates perfect lemon zest. It’s faster and more precise than a grater. I’ve had mine for 10 years—it’s that durable. The fine zest distributes evenly over the fish.

Fish Spatula

Transferring delicate fillets requires the right tool. A thin, flexible fish spatula slides under the fillets cleanly. Mercer Culinary’s offset version is my go-to. It prevents breaking the fish when moving from pan to plate.

Mixing Bowls

For the Cajun seasoning blend, a small stainless steel mixing bowl keeps everything contained. I prefer Winco’s 1-quart with a pour spout. It’s lightweight yet sturdy, and the spout helps avoid spilling when seasoning the fish. 💛
