Ingredients

Scale
  • 4 mahi mahi fillets (6 oz / 170 g each), skinless and boneless
  • 2 tablespoons smoked paprika
  • 1 teaspoon cayenne pepper
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon dried thyme
  • 1 teaspoon dried oregano
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 2 tablespoons olive oil or melted butter
  • 2 ripe mangoes, peeled and diced
  • 1 small red bell pepper, finely diced
  • ½ small red onion, finely chopped
  • 1 jalapeño, seeded and minced (optional)
  • ¼ cup fresh cilantro, chopped
  • Juice of 1 lime
  • Salt to taste
  • 1 teaspoon honey (optional)

Instructions

  1. In a small bowl, combine smoked paprika, cayenne pepper, garlic powder, onion powder, thyme, oregano, salt, and black pepper. Mix thoroughly.
  2. Pat mahi mahi fillets dry with paper towels. Rub both sides generously with the spice blend. Set aside.
  3. In a medium bowl, combine diced mango, red bell pepper, red onion, jalapeño (if using), and chopped cilantro. Squeeze lime juice over the top, add salt to taste, and stir gently. If mangoes are less sweet, drizzle honey and mix again. Cover and refrigerate until serving.
  4. Place cast iron skillet over medium-high heat and add olive oil or melted butter. Let the pan get hot but not smoking, about 2-3 minutes.
  5. Carefully place fillets in the hot skillet. Cook without moving for about 3-4 minutes until edges start to blacken and crust forms.
  6. Flip and cook another 3-4 minutes until fish is opaque and flakes easily with a fork. Fish should reach an internal temperature of 145°F (63°C).
  7. Plate each fillet and spoon fresh mango salsa generously on top or to the side. Garnish with extra cilantro or lime wedges if desired.

Notes

Use fresh spices for best flavor. Control heat to avoid burning spices. Pat fish dry before seasoning. Let salsa chill to meld flavors. Cook fish in batches if needed to avoid overcrowding the pan. For gluten-free and dairy-free options, verify spices and use olive oil instead of butter.
