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 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. Place 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 remaining fish; add 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.
Notes
Store leftover fish in an airtight container in the refrigerator for up to 2 days. Taco sauce can be stored refrigerated in a jar or airtight container for up to 1 week. Reheat fish in a covered skillet on low heat—avoid overcooking to maintain tenderness.

Common Mistakes to Avoid
Making Blackened Fish Tacos can be a breeze, but avoiding common pitfalls will enhance your dish. Here are some mistakes to steer clear of:
- Skipping the Marinade: Not marinating the fish reduces flavor. Always let it sit in seasoning for at least 15 minutes before cooking.
- Overcrowding the Pan: Adding too much fish at once can lower the skillet’s temperature. Cook in batches to ensure even cooking and a nice char.
- Using Low-Quality Fish: Using fresh, high-quality fish is key for great taste. Opt for wild-caught or sustainably sourced varieties whenever possible.
- Ignoring the Sauce: The chipotle-lime sauce is essential. Don’t skip it; it adds a creamy, spicy kick that complements the fish perfectly.
- Serving Cold Tortillas: Cold tortillas can ruin the taco experience. Always warm them up before serving for a better texture and taste.
