Description

Mahi mahi gets a spicy, quick makeover with this blackened seafood delight that brings Caribbean flair straight to your dinner table. Searing the fish in a hot cast-iron skillet creates a crispy, flavor-packed crust that makes weeknight cooking feel like a special culinary adventure.


Ingredients

Scale

Main Protein:

  • 4 mahi mahi fillets (6 ounces each)

Spices and Seasonings:

  • 1 tablespoon smoked paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon dried oregano
  • 1 teaspoon salt
  • ½ teaspoon cayenne pepper
  • ½ teaspoon freshly ground black pepper

Cooking and Serving:

  • 2 tablespoons olive oil
  • Lemon wedges
  • Chopped parsley (optional)
  • Salsa (optional)

Instructions

  1. Blend 1 tablespoon smoked paprika, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon dried oregano, ½ teaspoon cayenne pepper, 1 teaspoon salt, and ½ teaspoon black pepper in a small mixing bowl.
  2. Use paper towels to thoroughly dry your 6 oz mahi mahi fillets, removing excess moisture.
  3. Massage 2 tablespoons olive oil across both sides of each fillet, creating an even coating.
  4. Sprinkle the prepared spice mixture generously over the fillets, pressing gently to help seasonings adhere completely.
  5. Position a cast iron skillet over medium-high heat for 2-3 minutes until surface becomes extremely hot.
  6. Drizzle a small amount of olive oil into the skillet and carefully place seasoned fillets inside without overcrowding.
  7. Allow fillets to cook undisturbed for exactly 3-4 minutes, developing a deep brown crust.
  8. Carefully turn each fillet and continue cooking for another 3-4 minutes until internal temperature reaches 137-140°F.
  9. Check fish is flaky by gently prodding with a fork – it should separate easily.
  10. Remove skillet from heat and let fillets rest for 2 minutes to retain moisture.
  11. Serve immediately with fresh lemon wedges and your favorite side dishes.

Notes

  • Check your fish is patted completely dry before seasoning to ensure a crisp, well-crusted exterior that locks in moisture.
  • Preheat the cast iron skillet thoroughly so it creates an instant sear when the fish touches the surface, developing deep caramelized flavors.
  • Use fresh spices for maximum punch – older spice mixes lose potency and can make the blackening taste dull instead of vibrant.
  • Pescatarians and gluten-free diners can enjoy this recipe as-is, making it an excellent versatile seafood option that adapts easily to different dietary needs.
