Grilled Mahi Mahi

Ingredients

For the Fish:
1 ½ pounds mahi mahi fillets (about 4 fillets)
2 teaspoons garlic powder
2 teaspoons onion powder
2 teaspoons Old Bay seasoning
½ teaspoon salt
1 tablespoon olive oil

For Garnish:
Mango salsa
Lime wedges

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

Preheat Grill:

Preheat your grill to medium-high heat and ensure the grates are nice and hot.

Prepare Fish:

Pat the mahi mahi fillets dry with paper towels to remove excess moisture.
If using frozen fillets, thaw them first and gently press them with paper towels to remove excess water.

Season the Fish:

In a small mixing bowl, combine garlic powder, onion powder, Old Bay seasoning, salt, and olive oil. Whisk until the mixture is well combined.
Using gloved hands or a brush, apply the seasoning mixture evenly over the fillets.

Grill the Mahi Mahi:

Place the seasoned fillets on the hot grill.
Cook for 6 minutes, then carefully flip the fish using a fish spatula.
Cook for an additional 6 minutes on the other side, until the fish is opaque and flakes easily with a fork.

Tip: For perfect grill marks, place a cast-iron hamburger press on top of the fillets, applying light pressure. This helps cook the fish evenly and creates those desirable marks without squeezing out the juices.

Serve:

Remove the mahi mahi fillets from the grill.
Serve with fresh mango salsa and lime wedges for a refreshing and vibrant finish.
