- For the Chipotle Aioli:
- 1 tbsp apple cider vinegar
- ¾ tsp chipotle powder – not chili powder
- ½ tsp ground cumin
- ½ tsp salt – or to taste
- ⅛ tsp dried oregano
- ⅛ tsp garlic powder – not fresh garlic
- ½ cup mayonnaise – quality brand preferred
- 1 tbsp dijon mustard – adds depth
- 1 tbsp lime juice – fresh squeezed
- For Assembly:
- 16 corn tortillas – small size preferred

Marinate the Fish:
Combine sunflower oil, lime juice and zest, blackening seasoning, and kosher salt in a shallow dish. Coat the cod pieces evenly and refrigerate for 30 minutes, flipping once halfway through.
Make the Chipotle Aioli:
In a bowl, whisk together apple cider vinegar, chipotle powder, cumin, salt, oregano, and garlic powder. Add mayonnaise, dijon mustard, and lime juice. Mix until smooth. Taste and adjust as needed.
Cook the Cod:
Heat a heavy skillet (preferably cast iron) over medium-high heat. Add oil and butter. When hot, place marinated cod in the pan without overcrowding. Cook undisturbed for 3–4 minutes until a golden crust forms. Flip and cook another 2–3 minutes until opaque and cooked through.
Warm the Tortillas:
Heat corn tortillas over a gas flame or in a dry skillet until lightly charred and pliable. Keep warm wrapped in a clean towel.
Assemble the Tacos:
Start with warm tortillas. Add cabbage, then flaked cod. Drizzle with chipotle aioli. Top with pico de gallo and chopped cilantro. Serve with lime wedges.
Fish Alternatives: Mahi mahi, halibut, or tilapia can be used in place of cod. Make-Ahead Tip: Chipotle aioli can be made up to 3 days in advance. Dairy-Free Option: Use oil instead of butter and vegan mayo for aioli. Homemade Blackening Seasoning: Mix paprika, cayenne, garlic powder, onion powder, thyme, and oregano if store-bought isn't available. Storage: Store cooked fish and toppings separately. Reheat fish gently in a skillet. Serving Ideas: Pair with Mexican rice, beans, or avocado salad. Great for taco bars! Keyword blackened cod, fish tacos
