Instructions
 

  • Salt the defrosted filets and let them sit for 5 minutes. Then, pat them dry with a towel to remove excess moisture.
  • Lightly coat them with melted butter using a pastry brush.
  • Combine the ingredients for the blackened seasoning in a small bowl and generously cover both sides of the fish.
  • Warm avocado oil in a cast-iron skillet over medium heat until it begins to smoke.
  • Once heated, carefully add 1-2 filets to the pan to cook for 3-4 minutes on each side. Cooking time may vary depending on the thickness of the filet. Repeat with the remaining filets (see note).
  • Garnish with fresh lemon and serve with salad, rice, or pilaf.

Notes

Cooking Tips: 
  • The key to a well-seared fish is a well-coated, hot pan. Warm a cast-iron skillet on medium and give it time to heat up before cooking the fish. 
  • Mahi-mahi is versatile and cooks well, but it's still a lean fish; they will dry out if they overcook, and no one wants that.
  • When the fillet easily releases from the pan, it is done cooking. If it sticks, it's not quite ready. Give it more time. Use a food thermometer to check the temperature; the safe internal temperature for mahi-mahi is 137° F (58° C).
  • Speaking of hot- there could be a lot of smoke!! Do yourself a favor and turn on your exhaust fan. I often remember when it's already too late.
