Below, you’ll see how to use the oven to achieve a perfect blackened crust on your tilapia fish tacos. The rest is a cinch; all you have to do is assemble and EAT.

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!

Prep:

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.
