Equipment

  • Small Bowl
  • Medium bowl
  • Large grill pan or cast-iron skillet
  • Fish spatula or two forks
  • Chef's knife
  • Cutting board

Ingredients

For the Smoky Blackening Rub:

  • ½ tablespoon smoked paprika
  • 1 teaspoon onion powder
  • ¾ teaspoon kosher salt
  • ½ teaspoon garlic powder
  • ½ teaspoon dried thyme
  • ½ teaspoon black pepper
  • ¼ teaspoon cayenne pepper

For the Tacos:

  • ¾ pound 340 g skinless mahi-mahi fillets
  • 2 teaspoons avocado oil
  • 1 large navel orange
  • ¼ cup finely diced shallot
  • ½ medium jalapeño seeds removed and finely minced
  • 3 tablespoons chopped fresh cilantro plus extra leaves for garnish
  • 2 tablespoons fresh lime juice divided
  • ¾ cup finely shredded purple cabbage
  • 6 6-inch corn tortillas

Instructions

  • Make the Spice Rub: In a small bowl, combine the smoked paprika, onion powder, kosher salt, garlic powder, dried thyme, black pepper, and cayenne pepper. Mix until evenly distributed.
  • Season the Fish: Pat the mahi-mahi fillets completely dry with paper towels. Sprinkle the spice rub generously over all sides of the fish, gently pressing it into the flesh to ensure it adheres well.
  • Prepare the Citrus Salsa: Slice the top and bottom off the orange. Stand it on a cutting board and carefully cut away the peel and white pith. Holding the orange over a medium bowl to catch any juices, cut between the membranes to release the orange segments into the bowl. Add the diced shallot, minced jalapeño, chopped cilantro, and 1 tablespoon of the lime juice to the bowl. Stir gently to combine.
  • Cook the Fish: Heat the avocado oil in a large grill pan over medium heat. Once hot, place the seasoned fillets on the pan. Cook for 4-5 minutes per side, until the fish is opaque and flakes easily with a fork. The internal temperature should reach 145°F (63°C).
  • Assemble the Tacos: Transfer the cooked fish to a plate and let it rest for a minute. Use two forks to break it into large, bite-sized pieces, then drizzle with the remaining 1 tablespoon of lime juice. Warm the corn tortillas. To build the tacos, layer a bed of shredded purple cabbage on each tortilla, add a generous portion of the flaked fish, and top with the citrus salsa. Garnish with a few fresh cilantro leaves and serve immediately.

Notes

 

  • Fish Alternatives: If you can't find mahi-mahi, any firm white fish like cod, halibut, or snapper will work wonderfully in this recipe.
  • Heat Level: For a spicier taco, include some of the jalapeño seeds in your salsa. For a milder flavor, reduce the amount of cayenne pepper in the spice rub.
  • Storage: Store leftover fish and salsa in separate airtight containers in the refrigerator for up to 2 days. For best results, gently reheat the fish in a skillet rather than a microwave.
