Step 1

Preheat the grill to 400-450°F. Use a paper towel to pat the Mahi Mahi fillets to remove any excess moisture. Then brush them with olive oil on all sides.

Step 2

In a small bowl, combine the smoked paprika, onion powder, salt, pepper, sugar, garlic powder, dried thyme, dried or oregano, and cayenne pepper. Mix well. Sprinkle the blackened seasoning over the Mahi fillets on all sides. Gently rub to make sure the blackened seasoning sticks to the oil.

Step 3

Once the grill is hot, place the Mahi steaks on the hot grates and grill for 4-5 minutes, until the fish releases easily from the grates. If it's sticking, it's most likely not quite ready to flip.

Step 4

Flip the fish and continue to grill for another 3-4 minutes, for a total of 7-9 minutes cook time. Allow the fillets to rest for 2-3 minutes before serving.
