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.

Blackened Fish Taco Ingredients

Fish tacos are among the most simple taco recipes to make. All you need are fresh ingredients like the ones listed below:

Tilapia: makes a great option for fish tacos. It’s easy to cook with and flakes perfectly onto the tortilla. You could also use snapper, mahi-mahi, and flounder.
blackened seasoning: a mixture of cajun spices that coat each fish fillet and creates that blackened crust. I like using this blackened seasoning.
shredded cabbage: every fish taco needs a crunchy, fresh slaw. You can shred the cabbage or purchase a pre-bagged coleslaw mix.
fresh lime juice: tenderizes the cabbage.
salt: adds flavor to the slaw.
corn tortillas: use corn or flour tortillas, whichever your family prefers.
cilantro lime dressing: zesty flavors of lime and cilantro in a creamy dressing. Check out my recipe for cilantro lime dressing in the recipe card below!
cilantro: goes in the dressing and gets sprinkled over the finished tacos.

Ingredients

Scale

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

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. Bake for about 15 minutes, depending on the thickness of the fish until it’s cooked through and flakes easily.
While the fish is in the oven, toss the cabbage with the juice of 1 lime and salt in a medium bowl.
Make the cilantro-lime dressing in your blender and refrigerate until ready to 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.
