Easy blackened fish tacos made with fresh cilantro, purple cabbage, tomato, cotija cheese, lime juice, avocado, and chipotle mayonnaise.


  • 2 mahi mahi, cod, or haddock filets (about 1 pound)
  • 23 tablespoons blackening seasoning such as Old Bay
  • 1 tablespoon extra virgin olive oil for cooking
  • 1 package 5-6 inch corn tortillas
  • Fresh lime juice, for fish


  • Chipotle mayonnaise
  • 1 bag shredded purple cabbage or freshly shredded with a grater
  • 1 tomato, chopped
  • 23 tablespoons cilantro, chopped
  • 1 avocado, sliced
  • 1 lime cut into wedges
  • Grated cotija cheese

Blackening seasoning

  • 1 1/2 tablespoons paprika
  • 1 tablespoon garlic powder
  • 1 tablespoon onion powder
  • 1 tablespoon ground dried thyme
  • 1 teaspoon ground black pepper
  • 1 teaspoon cayenne pepper
  • 1 teaspoon dried basil


  1. Prepare all your taco toppings and set aside.
  2. If making your own blackening seasoning, combine all ingredients in a small bowl and mix. Note: you will not use all of it, you can save for later in a sealed container.
  3. Pat the fish dry with a paper towel and squeeze half a lime coating both sides of the fillets evenly. Rub both sides of the fish with blackening mix making sure the filets are generously seasoned.
  4. Meanwhile, heat the olive oil over medium-high heat in a skillet. Sear the fish until white and flaky and golden brown, about 5 minutes per side.
  5. Break apart the fish using the tip of your spatula into bite-sized chunks and serve on the skillet to keep warm.
  6. Warm the tortillas for 10-15 seconds in the microwave and assemble your blackened tacos with your desired toppings. Chopped tomato, sliced avocado, shredded cabbage, cilantro, and chipotle mayo. Serve with a lime wedge.
