This easy recipe for blackened fish tacos yields tender fish, a creamy dressing, and a crunchy slaw that make these the ULTIMATE fish tacos!

Spicy Blackened Fish Tacos

You can turn up the heat and make these spicy blackened fish tacos by adding a pinch of additional cayenne pepper to the blackened seasoning; which is exactly what sets these fish tacos apart from traditional recipes that use the classic taco seasoning.

While most blackened fish recipes are made in the skillet, I like to take the oven route. It’s more hands-free and still gives the fish a crispy, delicious crust with tender white flaky fish.

Ingredients

Tilapia is easy to cook and flakes perfectly onto the tortilla. You could also use snapper, mahi-mahi, and flounder. The blackened seasoning, a mixture of Cajun spices, creates the tasty blackened crust. Add a slaw for crunchiness and cilantro lime dressing, and taco night is ready to go!

Watch how it’s made:

Ingredients

  • 1 ½ pounds tilapia fillets
  • 2-3 tablespoons blackened seasoning
  • 2 cups shredded green and purple cabbage
  • 2 limes, 1 juiced and 1 cut into wedges
  • ½ teaspoon kosher salt
  • 12 corn tortillas, warmed
  • Cilantro Lime Sauce
  • Chopped fresh cilantro, additional for garnish

Instructions

Prep:

  • Preheat the oven to 425F and place a baking sheet in the oven.
  • Sprinkle both sides of the tilapia with the seasoning.
  • Using an oven mitt, remove the hot baking sheet from the oven. Generously coat the hot baking sheet with cooking spray and place the seasoned fish fillets on it. Spray the tops of the fillets and carefully return the baking sheet to the oven.

Cook:

  • Bake for about 15 minutes, depending on the thickness of the fish until it's cooked through and flakes easily.

Make the slaw:

  • While the fish is in the oven, toss the cabbage with the juice of 1 lime and salt in a medium bowl.

Make the dressing:

  • Make the cilantro-lime dressing in your blender and refrigerate until ready to assemble.

Assemble:

  • To assemble the tacos, place some slaw on each tortilla, top with chunks of blackened fish, and add a generous drizzle of cilantro-lime dressing. Sprinkle with cilantro and serve with lime wedges.
