The fish is seared in a hot skillet, four to five minutes on the first side and three to four on the second, until it reaches 145°F and lifts away browned.
The sauce is then made in the same pan: butter and garlic, half the diced mango, lime juice and zest, warmed for just a minute so the butter emulsifies without splitting.
How to Make It
Fish seasoned
Pat the fish dry and season with salt, pepper and paprika.
Seared to 145°F
Heat the oil in a large skillet over medium-high heat. Sear the mahi mahi 4 to 5 minutes on the first side and 3 to 4 minutes on the second, until browned and 145°F at the thickest point. Transfer to plates.
Butter and garlic
Reduce the heat to medium-low. Add the butter and garlic to the skillet and cook 30 seconds.
Mango and lime
Stir in half the diced mango, lime juice and lime zest and cook 1 minute, just until the mango warms and the butter emulsifies.
Plated
Spoon the mango-lime butter over the fish, top with the remaining fresh mango and cilantro, and serve with white rice and lime wedges.

Ingredient Notes
- Mahi mahi fillets
- Four at about six ounces each, patted dry before seasoning.
- Ripe mango
- One cup diced, half warmed in the sauce and half kept fresh.
- Cooked white rice
- Three cups, the accompaniment shown with the dish.
Success Tips
- Leave the fillets undisturbed for the first four minutes so a crust forms.
- Check the thickest part with a thermometer rather than guessing by colour.
- Make the sauce while the fish rests on the plates so it goes over hot.
Why This Recipe Works
- Patting the fillets dry is what allows them to brown rather than steam.
- Lowering the heat before the butter goes in keeps the sauce from splitting.
- Warming only half the mango leaves fresh fruit for the top.
- Lime zest carries more aroma than juice alone.
Serving Ideas
Set each fillet beside white rice, spoon the mango butter over and finish with fresh mango, cilantro and a lime wedge.
Storage and Reheating
Refrigerate
Refrigerate leftovers promptly; make the butter sauce fresh rather than reheating it.
