These blackened fish tacos come together in under 30 minutes and make a delicious weeknight meal. Spiced white fish is folded into warm tortillas, topped with shredded red cabbage and drizzled with a creamy avocado sauce.

You can make fish tacos with any firm white fish you prefer: tilapia, cod, mahi mahi, snapper, etc. I used Tilapia, it’s inexpensive, easy to cook and light in flavor.

To blackened the fish, rub it with spices and then sear it briefly at high heat until the outside just starts to blacken. The fish will be slightly crispy on the outside, moist, tender and flaky on the inside.

After seasoning the fish, let it sit for a while and prepare the rest of the ingredients before you start cooking it, because it cooks fast. It took only 4-5 minutes per side to cook my fish.

Feel free to add whatever toppings you’d like. I kept the toppings pretty simple. The avocado sauce is nothing more than mixing avocado with lime juice, Greek yogurt and cilantro.

For the cabbage slaw, I used a mixture of green and purple cabbage, which I lightly tossed in lime juice. You can add some mayo if you wish.

If you’ve never tried blackened fish tacos,  this is a great recipe – it’s quick, easy and delicious! I’m sure you’ll love them!

To make the cabbage slaw

  • Toss all ingredients together in a large bowl.

Cook the fish:

Assemble the tacos:

  • Start with 1 tortilla, layer the cabbage slaw first, then about 1/2 of a tilapia filet, some more slaw, cilantro, and drizzle with avocado sauce. Serve with a lemon wedge and your favorite beer!
