Cajun Blackened Fish Tacos are a bold and flavorful twist on the classic taco, inspired by the spicy, smoky cuisine of Louisiana. Blackening—a cooking technique that involves coating fish in a mixture of spices and searing it in a hot skillet—creates a deeply seasoned crust while keeping the fish tender and juicy inside. Paired with fresh toppings and soft tortillas, these tacos offer a perfect balance of heat, zest, and freshness that makes them a standout dish for casual meals or festive gatherings.
In this recipe, firm white fish such as cod, tilapia, or mahi-mahi is generously coated in a Cajun spice blend featuring paprika, cayenne, garlic, and herbs before being seared to develop a flavorful, slightly charred crust. The fish is then served in warm tortillas with toppings like shredded cabbage, avocado, lime crema, and fresh cilantro, adding crunch, creaminess, and brightness to balance the bold spices. Each bite delivers layers of flavor—from the smoky heat of the blackened fish to the tangy and refreshing toppings—creating a taco experience that’s both satisfying and exciting.
Perfect for weeknight dinners, summer cookouts, or taco nights, Cajun Blackened Fish Tacos are quick to prepare, bold in flavor, and endlessly customizable. They showcase how simple ingredients, fresh toppings, and bold spices can transform ordinary fish into a memorable, restaurant-quality meal at home. This dish celebrates the vibrant flavors of Cajun cooking in a fun and approachable way.

Instructions
Fish Taco Marinade: In a clean mixing bowl, combine all ingredients and mix well. Cut the white fish into 1-oz. pieces and place into the marinade, mixing everything together. Hold refrigerated for at least 12 hours.
Chipotle Aioli: Place all ingredients in a blender. Purée until everything is incorporated and the aioli is smooth in consistency. Transfer to a squeeze bottle with a small tip and refrigerate.
Lime Sour Cream: Place ingredients into a small, clean mixing and blend together well. Transfer to a squeeze bottle with a small tip and refrigerate.
Pico de Gallo:
Dice the yellow onion and tomato; mince the jalapeño. Place in a small, clean mixing bowl.
Wash and finely chop the cilantro; then add to the bowl.
Add the salt, lime juice and black pepper. Mix everything together well and hold refrigerated.
Asian Slaw: In a small, clean mixing bowl, mix all ingredients together.
Tacos:
Preheat a large sauté pan and melt the unsalted butter in the pan. Drain the marinated white fish and gently place into the melted butter. Spread the fish out evenly. Sprinkle the blackening spice evenly on the fish and let sit over high heat for 2 minutes. Flip the fish with a spatula and cook on the other side until the fish is completely cooked.
Turn the heat down to very low and hold hot.
Place the white corn tortillas into another large sauté pan and heat them on both sides. (Be sure the second pan is dry.)
Lay the hot corn tortillas on a clean cutting board and place 2 oz. of the cooked fish on each tortilla.
Top the fish with a little of the Asian Slaw.
Drizzle a little Chipotle Aioli, Lime Sour Cream and Pico de Gallo onto each tortilla.
