What is "blackened" fish?
Blackened fish is a cooking technique that involves coating fish with a blend of spices and then searing it in a cast-iron skillet until the outside is charred and the inside is cooked to perfection.
The seasoning used to blacken the fish typically includes a combination of paprika, cayenne pepper, garlic powder, onion powder, and other herbs and spices.
In this blackened cod recipe, we will be cooking the fish in the oven instead of the skillet for a foolproof hands-off meal.
💭Fun Fact: "Blackening" cooking method is popular in Cajun cuisine and originated in Louisiana, but has become popular across the United States and beyond.

Make it Nutrient Dense
Staying true to the heart of what Prepare and Nourish is all about, there are ways to ensure you get the maximum nutrition in this fish taco recipe. Even though it's an incredibly simple recipe, you can take purposeful steps to turn this into a nutrient-dense meal.
Source wild fish. I mostly get our wild seafood at Costco and they have wild cod regularly - both the large fillets and the smaller individual serving-size in the freezer section.
Homemade creamy sauce. Use homemade mayonnaise as the base for the creamy cabbage slaw.
Use sprouted tortillas. We love the Ezekiel flourless tortillas made with whole sprouted grains. They also have sprouted corn tortillas that are equally delicious.
Make it grain free. To convert this fish tacos recipe into paleo fish tacos - use large lettuce leaves instead of tortillas. Butter lettuce leaves are an excellent option as they are hardy to hold all the fish taco contents. Because the rest of the ingredients are naturally sugar-free and grain-free, using a lettuce leaf makes these Whole30 fish tacos.
Time-saving tip - Make a double batch of the blackened seasoning mix and have some on hand to save time.
Money-saving time - Use frozen fish instead of fresh as it's often more affordable, and you can stock up and always have some on hand for quick and easy meals.
Make-ahead tip - Prep everything ahead of time and keep everything in the fridge until ready to assemble.

The recipe for blackened cod tacos is very straightforward and comes together quickly and effortlessly.
Step 1. Bake fish
Pat dry the fish fillets with a paper towel to remove excess moisture. Coat the fish well with Cajun seasoning on both sides and bake in a preheated oven until cooked through and the fish flakes.
💭Pro tip: Baking time will vary depending on the thickness of the fish. Use an instant-read meat thermometer to ensure the internal temperature of the fish reaches 145°F (63°C). Or cook fish until it flakes easily.
Step 2. Combine slaw
Toss the shredded cabbage with mayonnaise, sriracha, and lime juice in a large bowl until combined. Set aside.
Alternatively, double this creamy sriracha mayo recipe in a small bowl and save some to drizzle on the cod fish tacos.
Step 3. Prep toppings
Prepare the rest of the ingredients by dicing or slicing tomatoes, avocado, cilantro, and green onions and spread them across a platter or serving board.
Step 4. Assemble tacos
Warm tortillas on medium heat on an open flame or cast iron skillet.
Add coleslaw to the bottom of the tortilla, followed by flaked fish and the rest of the toppings. Drizzle with sriracha if desired, and serve.
💭Pro tip: You can bake the fish in an air fryer at the same temperature but check on it earlier to make sure you don't overcook it.
