Louisiana Blackened Fish Tacos

The smoke alarm went off twice the first time I attempted blackened fish, but my roommate didn't even mind once she took that first bite. We'd been craving something that felt like summer in the middle of February, and these tacos somehow transported us straight to a Gulf Coast patio. Now every time I smell paprika hitting hot oil, I'm back in that tiny kitchen with windows thrown open to the winter air.

I made these for my sister's birthday dinner last spring, and she literally stopped midconversation after her first taco. We sat on the back porch as the sun went down, passing around platters and squeezing lime wedges over everything. She still texts me randomly asking when I'm going to make them again.

Ingredients

• White fish fillets: Tilapia, catfish, or cod work beautifully here because they're mild enough to let the spices shine but sturdy enough to handle high heat without falling apart
• Paprika: This forms the base of your blackening rub and gives that gorgeous reddish brown color we're after
• Garlic and onion powder: These build that savory backbone that makes the spice blend taste complex and restaurant quality
• Dried thyme and oregano: Earthy herbs that ground all that heat and add traditional Cajun depth
• Cayenne pepper: Adjust this based on your heat tolerance, but don't skip it entirely or you'll lose that signature blackened kick
• Green and red cabbage: The combination looks stunning and provides satisfying crunch that contrasts with the tender fish
• Fresh cilantro: Brightens everything up and adds that fresh herbal note that cuts through the rich spices
• Sour cream and mayonnaise: Together they create the perfect creamy base for your crema, tangy enough to stand up to all those bold flavors
• Lime juice: Use generously in both the slaw and crema, it's the acid that ties all the components together
• Corn or flour tortillas: Warm them properly and they become the perfect vessel for all these incredible layers

Instructions

Get your slaw ready first:

Toss both cabbages and grated carrot with fresh cilantro in a large bowl, then whisk together lime juice and mayonnaise with salt and pepper before coating the vegetables thoroughly. Let it hang out while you prep everything else, those flavors need time to become friends.

Make your blackening magic:

Combine paprika, garlic powder, onion powder, thyme, oregano, cayenne, black pepper, and salt in a small bowl. Take a moment to appreciate how good this smells already, you're building something special here.

Prep your fish like a pro:

Pat those fillets completely dry with paper towels, brush both sides with olive oil, then press the spice mixture into the fish until it's thoroughly coated. Don't be shy with the rub, you want that thick crust that creates the blackened effect.

Create the perfect sear:

Get your cast iron screaming hot over medium high heat, really let it heat up for a few minutes, then carefully lay in your fish. Let it cook undisturbed for 2 to 3 minutes until that spice crust forms, flip, and cook until the fish flakes easily with a fork.

Whip up the crema:

Mix sour cream, mayonnaise, lime juice, hot sauce if you're feeling brave, and a pinch of salt until smooth and creamy. Taste and adjust, you want it tangy enough to make your mouth pucker just a little.

Bring it all together:

Cut your rested fish into bite sized pieces, pile them into warm tortillas, heap on that colorful slaw, and drizzle generously with crema. Squeeze fresh lime over everything right before eating, it wakes up all the flavors.

These tacos turned a regular Tuesday dinner into something my friends still talk about months later. There's something about combining that spicy smoky fish with cool crunchy slaw that just makes people happy, plus they look gorgeous on the table.

Perfecting Your Blackening Technique

I've learned that getting that restaurant quality blackened crust is all about patience and heat management. Don't rush the preheating phase, and resist the urge to check the fish too early, that crust needs time to form properly. A cast iron skillet really is your best friend here, it holds heat evenly and creates the most beautiful sear.

Making It Your Own

Sometimes I add sliced radishes to the slaw for extra crunch and a pop of color, or throw in some diced mango when I want sweetness to balance the heat. The beauty of this recipe is how adaptable it is while still delivering those bold Cajun flavors everyone loves.

Serving Suggestions

These tacos are substantial enough to stand alone as dinner, but a simple side of Mexican rice or black beans would round out the meal beautifully. I love setting up a taco bar and letting everyone build their own, it turns dinner into an interactive experience.

• Keep extra lime wedges on the table, people will want them
• Have cold drinks ready, the heat sneaks up on you
• Warm your tortillas over an open flame for those authentic charred spots

Hope these tacos bring as much joy to your table as they've brought to mine over the years. There's nothing quite like watching friends take that first bite and see their eyes light up.
