Ingredients

Scale

The Protein & Searing Oil:

  • 4 Mahi Mahi fillets (Fresh, or completely thawed if frozen)
  • 1 tablespoon Avocado Oil (Do not substitute with butter or olive oil!)

The Blackening Spice Blend:

  • 1 teaspoon Smoked Paprika
  • 1 teaspoon Garlic Powder
  • 1 teaspoon Onion Powder
  • 1/2 teaspoon Ground Cumin
  • 1/2 teaspoon Dried Oregano
  • 1/4 teaspoon Cayenne Pepper (Adjust if you prefer less heat)
  • 1 pinch Sea Salt

The Fresh Mango Salsa:

  • 1 ripe Mango (Peeled and finely diced)
  • 1/4 Red Onion (Finely chopped)
  • 1/2 Jalapeño (Seeds removed and finely diced)
  • 2 tablespoons Fresh Cilantro (Finely chopped)
  • 1 Lime (Juiced)

Instructions

  1. The Salsa Prep: In a small glass bowl, toss together the diced mango, red onion, jalapeño, fresh cilantro, and lime juice. Place the bowl in the refrigerator so the flavors can mingle while you prepare the fish.
  2. Dry the Fish: Use paper towels to aggressively pat the Mahi Mahi fillets completely dry on both sides. If the fish is wet, it will steam instead of forming a crust!
  3. The Spice Coat: In a small dish, mix the smoked paprika, garlic powder, onion powder, cumin, oregano, cayenne, and sea salt. Press this dry spice mixture heavily and evenly onto both sides of the dry fish fillets.
  4. The Screaming Hot Pan: Place a heavy cast-iron skillet over medium-high heat. Add the avocado oil and allow it to heat up until it is rapidly shimmering and very hot.
  5. The Sear: Carefully place the spiced fish into the hot skillet. Do not touch, poke, or move the fish for exactly 3 to 4 minutes! Leaving it undisturbed is the absolute secret to forming the dark, signature crust.
  6. The Flip & Serve: Gently flip the fish with a spatula and cook for an additional 3 minutes, or until the center is entirely opaque and flakes easily with a fork. Remove from the heat, top immediately with the cold mango salsa, and serve warm.

Notes

  • Avocado Oil is Mandatory: To truly “blacken” fish, you need intense heat. Avocado oil has a smoke point of 520°F. If you use butter or standard olive oil, it will burn instantly, fill your kitchen with smoke, and turn your fish bitter.
  • Mango Ripeness: Choose a mango that gives slightly to a gentle squeeze. If it is rock hard, the salsa will be too tart and crunchy.
