How to Make Blackened Fish Tacos

Step 1: Make the Taco Sauce

In a food processor or blender, combine lime juice, sour cream, mayonnaise, garlic salt, chipotle pepper, and chopped cilantro. Blend until smooth. Taste and adjust seasoning as needed. Refrigerate until ready to serve.

Step 2: Prepare the Blackening Seasoning

In a bowl, mix together garlic powder, paprika, onion powder, cayenne pepper, thyme, basil, oregano, salt, and black pepper until well combined.

Step 3: Season the Fish

Place the melted butter in a shallow bowl. Dip each piece of fish into the butter to coat all sides. Place on a plate and generously sprinkle blackening seasoning over both sides of each fillet.

Step 4: Cook the Fish

Heat olive oil in a cast iron skillet over medium-high heat. Carefully add the seasoned fish and sauté for about 2 minutes per side until cooked through and flaky. Transfer cooked fish to a paper towel-lined plate. Repeat with remaining fish, adding more oil if necessary between batches.

Step 5: Assemble the Tacos

Warm tortillas and fill each with shredded cabbage, a piece of blackened fish, chopped cilantro, Cotija cheese, and a drizzle of chipotle-lime sauce. Serve with lime wedges on the side and enjoy immediately!

How to Serve Blackened Fish Tacos

Blackened Fish Tacos are a delightful and versatile dish that can be served in many ways. Whether you’re hosting a casual gathering or enjoying a family dinner, these tacos can be customized to please everyone.

Taco Bar

Set up a taco bar: Lay out all the ingredients so guests can create their own tacos. Include toppings like avocado, salsa, and hot sauce for added flavor.

Fresh Sides

Serve with fresh sides: Pair your tacos with fresh sides like guacamole or pico de gallo to enhance the meal and add vibrant colors to your table.

Garnish Options

Add garnishes: Top each taco with extra cilantro, lime wedges, or radishes for a pop of flavor and crunch.

How to Perfect Blackened Fish Tacos

To achieve the ultimate Blackened Fish Tacos, follow these simple tips to ensure flavorful and perfectly cooked fish every time.

Use high-quality fish: Select fresh white fish fillets like tilapia or mahi-mahi for the best flavor and texture.
Don’t skip the seasoning: Generously apply blackening seasoning to enhance the taste of the fish. This step is key to delivering that authentic flavor.
High heat cooking: Ensure your skillet is hot before adding the fish. This helps achieve a nice blackened crust while keeping the inside tender.
Rest after cooking: Let your cooked fish rest for a few minutes before assembling tacos. This allows juices to redistribute and enhances moisture.
Warm tortillas properly: Warm your corn tortillas in a dry skillet for 30 seconds on each side. This makes them more pliable and prevents tearing when filled.

Best Side Dishes for Blackened Fish Tacos

To round out your meal, consider serving these delicious side dishes alongside your Blackened Fish Tacos. Each option complements the bold flavors perfectly.

Mexican Street Corn (Elote): Grilled corn on the cob slathered in mayo and topped with cheese and chili powder makes a fantastic side.
Black Bean Salad: A refreshing mix of black beans, corn, bell peppers, and cilantro tossed in lime juice adds protein and zest.
Cilantro Lime Rice: Fluffy rice flavored with cilantro and lime offers a mild accompaniment to balance the spicy tacos.
Chips and Salsa: Crunchy tortilla chips served with fresh salsa or guacamole are always a crowd-pleaser.
Grilled Vegetables: Seasonal veggies grilled until charred provide a healthy addition that pairs well with tacos.
Avocado Salad: A light salad featuring creamy avocado slices mixed with tomatoes and onions enhances freshness on your plate.

Common Mistakes to Avoid

When making Blackened Fish Tacos, it’s easy to overlook a few details that could affect your dish. Here are some common mistakes people make and how to avoid them.

Skipping the Seasoning: Failing to generously season the fish can lead to bland tacos. Make sure to coat the fish well with the blackening spices for maximum flavor.
Overcooking the Fish: Cooking the fish for too long can dry it out. Keep an eye on it, as fish cooks quickly—about 2 minutes per side is usually enough.
Using Cold Tortillas: Serving cold tortillas can make your tacos less appealing. Always warm your corn or flour tortillas before assembling for better texture and taste.
Not Adjusting the Sauce: Some may overlook tasting and adjusting the taco sauce. Make sure to blend and taste it before serving; adding more lime or chipotle can enhance its flavor.
Ignoring Fresh Ingredients: Using old or wilted produce can diminish your taco’s quality. Always choose fresh cilantro, cabbage, and limes for a vibrant dish.

Refrigerator Storage

Store leftover Blackened Fish Tacos in an airtight container.
They will last for up to 2 days in the refrigerator.

Freezing Blackened Fish Tacos

While it’s best to enjoy these tacos fresh, you can freeze cooked fish separately.
Place cooked fish in a freezer-safe bag; it will last up to 3 months.

Reheating Blackened Fish Tacos

Oven: Preheat the oven to 350°F (175°C). Place fish on a baking sheet covered with foil and heat for about 10 minutes until warmed through.
Microwave: Heat fish in short intervals of 30 seconds until just warm, being careful not to overcook.
Stovetop: Reheat in a skillet over low heat, covering with a lid to retain moisture and warmth.
