Ingredients

Scale
  • 4 mahi mahi fillets (6 oz / 170 g each)
  • 2 tsp smoked paprika
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 tsp dried thyme
  • 1 tsp cayenne pepper (adjust based on heat preference)
  • 1 tsp black pepper
  • 1 tsp salt
  • 2 tbsp olive oil or avocado oil
  • 1 ripe mango, diced
  • 1 ripe avocado, diced
  • 1 small red onion, finely chopped
  • 1 jalapeño, seeded and minced (optional)
  • Juice of 1 lime
  • 1/4 cup fresh cilantro, chopped
  • Salt to taste
  • 810 small corn or flour tortillas, warmed
  • Optional toppings: shredded cabbage, sour cream or crema, extra lime wedges

Instructions

  1. Prepare the blackening spice mix by combining smoked paprika, garlic powder, onion powder, dried thyme, cayenne pepper, black pepper, and salt in a small bowl. Stir well.
  2. Pat the mahi mahi fillets dry with paper towels. Sprinkle both sides generously with the blackening spice mix and let rest for 5 minutes.
  3. Make the mango avocado salsa by combining diced mango, avocado, red onion, jalapeño (if using), and chopped cilantro in a medium bowl. Squeeze lime juice over the mixture, toss gently, and add salt to taste. Set aside.
  4. Heat a non-stick or cast-iron skillet over medium-high heat and add 2 tablespoons of olive or avocado oil. Heat until shimmering but not smoking.
  5. Sear the mahi mahi fillets in the skillet without moving for 3-4 minutes until a dark, crispy crust forms. Flip gently and cook the other side for another 3-4 minutes until opaque and flaky.
  6. Warm the tortillas in a dry skillet or microwave for 20-30 seconds until soft and pliable.
  7. Assemble the tacos by placing pieces of blackened mahi mahi on each tortilla. Top with mango avocado salsa and optional toppings like shredded cabbage or sour cream. Serve immediately with extra lime wedges.

Notes

Pat the fish dry before seasoning to ensure a good crust. Use oils with high smoke points like avocado or olive oil. Avoid overcrowding the pan to maintain heat. Let the fish rest after cooking for moist, tender bites. For gluten-free, use corn tortillas. For dairy-free, substitute sour cream with coconut yogurt or omit toppings.
