Preheat grill and make sure your grates are nice and hot.Once the grill is preheated, you can oil the grates with a grill spray to ensure your protein doesn't stick!
Pat mahi mahi filets dry with paper towels.
1 1/2 pounds mahi mahi filets
Combine all seasonings with the olive oil and whisk until completely mixed.
2 teaspoons garlic powder, 2 teaspoons onion powder, 2 teaspoons Old Bay seasoning, 1/2 teaspoon salt, 1 Tablespoon olive oil
Using gloved hands, brush oil mixture over the fish filets. Alternatively, you can use your gloved hands to rub the mixture on.
Place seasoned filets onto hot grill. Allow to cook for 6 minutes before turning them over with fish spatula. Cook another 6 minutes on the other side.TIP - For really nice grill marks, we use a cast iron hamburger press placed gently on top of the filets. Chef Antoine applies a very light amount of pressure to the press. You don’t want to squeeze the juices out, you only want to get those nice grill marks and it helps the fish cook evenly!
If using frozen filets, thaw them first and very gently press them to remove excess surface water with paper towels. Be gentle, you don’t want to dry them out, just dry the surface.
We’ve found that the filets inside packs of frozen mahi mahi can really vary in size. The filets used in this recipe were from a frozen pack and were a nice healthy size. A second pack we purchased (same brand) had considerably smaller filets. Keep this in mind when shopping and when grilling as smaller filets will take less time to cook.
