We eat blackened fish tacos at least once a month. They never get old. I like them better than traditional beef or chicken tacos at this point. I hate to brag about my own recipes (obviously I’m biased), but I think this may be my favorite recipe on this blog. Fish tacos are AWESOME. In my opinion, the key is the chipotle mayonnaise topping. It adds a nice spicy, creamy kick. I like to spread it on my tortillas before adding the blackened fish and toppings.
For this recipe I used catfish. It’s very easy to cook and light in flavor. It will not overpower the spices or toppings. You could also substitute with tilapia or mahi mahi if you prefer. Rub the fish filets heavily with blackening mix…and I mean heavily—the more seasoning, the more flavor. Some blackening mix can be a little spicy so be sure to taste a little before using.
I usually sear the blackened fish in a cast iron skillet and serve in the skillet to keep warm. Cast iron gives you the grill-like seared finish. Assemble fish tacos with avocado, cilantro, cabbage, tomatoes, chipotle mayonnaise, and fresh lime. So simple, yet incredible. Try to find small white corn tortillas. They are lower in fat and have less carbs than your traditional white tortilla. Altogether this is a relatively light dinner that’s packed with flavor and fresh ingredients.

What brand Chipotle mayo do you recommend?
Hi Julie,
I use Kraft chipotle mayo. It’s perfect.
