Blackened Fish Tacos with tender tilapia, sweet and spicy Mango Salsa and tangy Mexican Cabbage Slaw explode with Cajun Mexican flavor in this quick and easy dinner that everyone will love!

Why You’ll Love These Blackened Fish Tacos

These Blackened Fish Tacos are not like typical fish tacos in San Diego because this fish is not battered and fried like Baja California Fish Tacos and doesn’t have a Baja fish taco sauce.

However, Blackened Fish Tacos are spicy, delicious and are topped with a Mexican Cabbage Slaw, sometimes called Fish Taco Slaw, and/or Mango Salsa. So if you have had Fish Tacos with Mango Salsa before, this recipe will be more similar to those tacos, only spicier and more flavorful. If you loved my Blackened Mahi Mahi Fish Sandwiches, you’ll love these fish tacos!

The other reason to love these Blackened Fish Tacos is that not only do they taste good, they are good for you! With nothing but seasoned fish, fruit, and vegetables, you can feel good about eating this and serving it to family and friends.

Last but not least, they come together really quickly. If you make the Mango Salsa and Mexican Cabbage Slaw ahead of time, these tacos can be on the table in under 30 minutes!

Taco Aficionado

To say my family loves tacos is an understatement. We have had tacos at least once every couple of weeks for years, since I was a kid. Usually, on Fridays we eat fish tacos. My favorite is the Blackened Fish Tacos. So I guess that makes me a Taco A”Fish”ionado. 

I owe the love of fish to my Mom and the love of the spice to my Dad. My Mom would make the fish without the seasoning. But then on another batch my Dad would add the blackened seasoning. I always waited for my Dad’s batch of Blackened Fish Tacos.

Then after I moved out, I married a man who loved spicy foods too. So for the last two plus decades, I make Blackened Fish Tacos at least once every couple of weeks. I alternate them with the Cajun Blackened Chicken. Therefore, I have perfected the recipe over the years and am sharing it with you today.

What Is Blackening Seasoning?

Cajun Blackening Seasoning is a Cajun spice mix with salt, black pepper, (heavy on the black pepper), and other spices that are likely already in your pantry. You can use store bought seasoning or make your own using the recipe on this site. I recommend making a batch and keeping it on hand to use on not only these fish tacos, but also on Cajun Blackened Chicken, Blackened Salmon, or Blackened Catfish.

What Type Of Fish To Use For Fish Tacos

According to Food & Wine Magazine, the best fish for fish tacos are mild flavored white-fleshed salt-water fish, as as the following types:

• Tilapia
• Cod
• Mahi Mahi
• Halibut
• Flounder

In this recipe, I used Tilapia for the fish tacos but any of the above fish would work well also. It is also delicious made with shrimp!

How To Make Blackened Fish Tacos

Below are instructions on how to make Blackened Fish Tacos. In addition, the photo collage below the instructions displays the step by step process of how to make Blackened Fish Tacos. The numbers in the photo collage match to the numbers in the instructions below.

1. Make the Cajun Blackened Seasoning (if making it from scratch), Mexican Cajun Slaw, and Mango Salsa before starting to cook the fish. See those recipes on this site for the detail instructions.
2. Place the fish filets on a large plate or baking sheet.  Sprinkle the Cajun Blackening Seasoning on each side of the fish filets.
3. In a large skillet over medium heat, add oil. After the oil is hot, add the fish filets and cook for about 5 minutes. Turn and cook for another 4 or 5 minutes on the other side.
4. Remove the Blackened Fish from the skillet and place on a clean plate or platter. Slice the filets into small pieces to fit into the tacos.
5. Wrap the tortillas in paper towels and place on a plate. Heat for about 1 minute. Remove and add them to your assembly line to assemble the tacos.
6. Stuff each tortilla with the blackened fish, slaw, and mango salsa. Serve hot. Enjoy!
