Ingredients

Blackening Seasoning
- 1 tablespoon paprika
- 2 teaspoons ancho chile powder
- 1 teaspoon smoked paprika
- ½ teaspoon cayenne pepper
- 1½ teaspoons ground cumin
- ¾ teaspoon ground coriander
- 1½ teaspoons garlic powder
- 1½ teaspoons onion powder
- 1 teaspoon dried oregano
- 2 teaspoons fine sea salt
Blackened Fish Tacos
- 1½ pounds cod fillets
- 3 tablespoons salted butter, divided
- ¼ cup mayonnaise
- ¼ cup sour cream
- 1 tablespoon fresh lime juice
- 2 cups shredded cabbage
- ½ cup pico de gallo (homemade or store-bought)
- Corn tortillas, warmed
- Lime wedges, for serving
Instructions
- In a small bowl, whisk together the paprika, ancho chile powder, smoked paprika, cayenne pepper, cumin, coriander, garlic powder, onion powder, oregano, and sea salt to make the blackening seasoning.
- Pat the cod fillets dry with paper towels, then coat them generously with the seasoning blend. Reserve 1 teaspoon of the seasoning for the sauce. Let the fish marinate for at least 30 minutes or up to 3 hours in the refrigerator.
- In a separate bowl, whisk together the mayonnaise, sour cream, lime juice, and the reserved teaspoon of blackening seasoning until smooth and creamy. Cover and refrigerate until ready to serve.
- Heat a large nonstick skillet over medium heat. Melt 1 tablespoon of butter until foamy.
- Add the seasoned fish in a single layer without overcrowding the pan. Cook for 3–4 minutes per side until beautifully blackened and the fish flakes easily with a fork. Add additional butter as needed while cooking the remaining fillets.
- Transfer the cooked fish to a plate and gently break it into large bite-sized pieces.
- Warm the corn tortillas in a dry skillet or directly over a gas flame for a few seconds per side.
- Assemble the Blackened Fish Tacos by filling each tortilla with flaky cod, shredded cabbage, pico de gallo, and a generous drizzle of the creamy lime sauce.
- Serve immediately with fresh lime wedges for squeezing over the tacos.

Tips & Tricks
- Pat the fish dry before seasoning to help create a flavorful crust.
- Cod, mahi-mahi, halibut, tilapia, or haddock all work wonderfully.
- Avoid overcrowding the skillet so the fish browns instead of steaming.
- Warm tortillas before serving to make them soft and flexible.
- Add sliced avocado, fresh cilantro, pickled onions, or jalapeños for extra flavor.
- Reduce the cayenne pepper for a milder version or increase it for extra heat.

FAQ
What is the best fish for Blackened Fish Tacos?
Firm white fish like cod, mahi-mahi, halibut, tilapia, and haddock are excellent choices because they stay moist and flaky while holding up well to the bold seasoning.
Can I bake the fish instead of pan-searing it?
Yes. Bake the seasoned fish at 400°F (200°C) for 12–15 minutes, depending on thickness, until it flakes easily with a fork.
Are Blackened Fish Tacos spicy?
They have a mild to medium level of heat. Reduce or omit the cayenne pepper if you prefer a milder flavor.
Can I prepare the sauce ahead of time?
Absolutely. The creamy lime sauce can be made up to two days in advance and stored in the refrigerator.
What toppings go well with fish tacos?
Avocado, cilantro, pickled onions, jalapeños, cotija cheese, mango salsa, corn salsa, and shredded lettuce all make delicious additions.
Storage
Store leftover cooked fish and sauce separately in airtight containers in the refrigerator for up to 3 days. For longer storage, freeze the cooked fish for up to 2 months and thaw overnight in the refrigerator before reheating. Warm the fish gently in a skillet over medium-low heat or in a 300°F oven until heated through. Assemble the tacos just before serving for the freshest texture.
