For 4 servings
- prep
Preheat the grill.
Heat an outdoor grill or stovetop grill pan to medium-high. Brush the grates clean, then oil them lightly with a folded paper towel dipped in olive oil.
TIPProperly heated and oiled grates are essential — mahi-mahi is lean and will stick to a cold or dry grill. - mix

Season the mahi-mahi fillets.
1.Pat the fillets completely dry with paper towels.2.Brush both sides lightly with olive oil.3.Season both sides with a pinch each of salt, black pepper, garlic powder, and smoked paprika.TIPDon't skip drying the fillets — excess moisture creates steam on the grill and prevents a good sear. - grill · ~8 min
Grill the mahi-mahi.
Place fillets on the hot grill at a slight diagonal angle. Cook undisturbed for 4 minutes until the bottom releases easily and grill marks form. Flip carefully with tongs and cook another 3 to 4 minutes until the fish is opaque throughout and flakes easily with a fork.
TIPDon't move the fish for the first 4 minutes — it will release naturally from the grates once properly seared. - rest · ~2 min
Rest the fillets briefly.
Transfer grilled fillets to a plate and let rest for 2 minutes. This allows the juices to redistribute so the fish stays moist.
- assemble
Plate and top with mango salsa.
Place each fillet on a serving plate and spoon a generous mound of mango salsa over the top. Serve immediately with any extra salsa on the side.
What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.

- 2Oil your grill grates just before adding the fish — use a folded paper towel dipped in oil and tongs.
- 3Let the mango salsa sit for at least 10 minutes so the lime juice softens the onion and melds the flavors.
- 4Grill the mahi-mahi undisturbed for 4 minutes on the first side; it will release easily when properly seared.
- 5Use a thin, flexible fish spatula to flip the fillets gently without breaking them.
