How to Make Blackened Fish Tacos
Step 1: Make the Taco Sauce
In a food processor or blender, combine lime juice, sour cream, mayo, 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 garlic powder, paprika, onion powder, cayenne pepper, thyme, basil, oregano, salt, and black pepper.
Step 3: Season the Fish
Place melted butter in a shallow bowl. Dip each piece of fish into the butter to coat all sides before placing it on a plate. 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 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 any remaining fish.
Step 5: Assemble the Tacos
Warm tortillas and fill each with shredded cabbage. Add a piece of blackened fish on top followed by chopped cilantro, Cotija cheese, and drizzle with chipotle-lime sauce. Serve with lime wedges on the side and enjoy immediately!

How to Perfect Blackened Fish Tacos
Creating perfect Blackened Fish Tacos is all about mastering the technique and balancing flavors. Here are some tips to ensure your tacos turn out amazing every time.
- Use Fresh Ingredients: Fresh fish and produce make a significant difference in taste and texture.
- Properly Heat Your Skillet: Ensure your skillet is hot enough before adding the fish; this helps achieve that desirable blackened crust.
- Don’t Overcrowd the Pan: Cook in batches if necessary; overcrowding can lower the pan’s temperature and affect cooking.
- Adjust Seasoning to Taste: Feel free to tweak the spice levels based on your preference—add more cayenne for heat or reduce it for milder tacos.
- Let Fish Rest After Cooking: Allowing cooked fish to rest briefly helps retain moisture before assembling tacos.
- Warm Tortillas Properly: Warm tortillas on a skillet just before serving to enhance their flavor and pliability.
Best Side Dishes for Blackened Fish Tacos
Pairing side dishes with Blackened Fish Tacos can create a complete meal experience. Here are some delicious options you can consider.
- Mexican Street Corn Salad: A refreshing salad made with corn, lime, cheese, and spices that offers crunchy textures.
- Refried Beans: Creamy refried beans add richness and are perfect for scooping up with tortillas.
- Chips with Salsa Verde: Crispy tortilla chips served with zesty salsa verde make for an addictive appetizer.
- Mango Slaw: A sweet and tangy mango slaw balances the spicy fish perfectly.
- Avocado Tomato Salad: This light salad provides creaminess from avocados paired with juicy tomatoes.
- Cilantro Lime Rice: Fluffy rice flavored with cilantro and lime complements tacos wonderfully while adding substance.
Common Mistakes to Avoid
When making Blackened Fish Tacos, it’s easy to run into a few common pitfalls. Here are some mistakes to avoid for the perfect taco experience.
- Using the wrong fish: Choosing a fish with a strong flavor can overpower the spices. Opt for mild white fish like tilapia or cod for best results.
- Overcooking the fish: Cooking fish too long can lead to dryness. Aim for a flaky texture by cooking just until it turns opaque.
- Skipping the seasoning: Failing to properly season your fish can result in bland tacos. Generously coat the fillets with the blackening seasoning before cooking.
- Not warming the tortillas: Serving cold tortillas can ruin the taco experience. Warm them on a skillet or in the microwave for optimal taste and texture.
- Ignoring toppings: Toppings add flavor and crunch. Don’t skimp on fresh ingredients like cabbage, cilantro, and Cotija cheese.
Storage & Reheating Instructions
Refrigerator Storage
- Store leftover blackened fish in an airtight container in the refrigerator for up to 2 days.

Freezing Blackened Fish Tacos
- Wrap individual tacos tightly in plastic wrap and place them in a freezer-safe bag.

Reheating Blackened Fish Tacos
