Coconut-Crusted Mahi-Mahi with Mango Salsa in One Skillet

Crisp coconut crust meets tender, flaky fish in this quick skillet dinner. Two mahi-mahi fillets are pressed into shredded coconut, seared in a cast iron pan with butter, and finished with a bright mango salsa of red onion, cilantro and lime. The result is golden, sweet, savory and ready in about thirty minutes.

This is a weeknight dinner built around a single skillet and a short ingredient list. Mahi-mahi is a firm, mild fish that holds its shape in the pan, which makes it an excellent partner for a coconut crust. Unsweetened shredded coconut toasts to a golden, crunchy coating that adds texture without making the fish sweet.

A fresh mango salsa, brightened with red onion, cilantro and a squeeze of lime, provides contrast in both temperature and flavor. Serve it right away so the crust stays crisp and the salsa keeps its fresh bite. Read through the steps once before you start, so the coconut, the salsa and the skillet are ready at the same time.

Ingredients

Why this recipe works

The method works because the coconut is pressed firmly onto a dry, seasoned fillet, so it adheres during cooking rather than sliding off into the pan. Heating the oil until it shimmers before adding the melted butter gives a hot surface that sears the coconut quickly.

The butter contributes browning and a rich flavor, while the oil keeps the butter from burning at the start. Cooking each side until the coconut turns golden brown lets the crust set into a crisp layer, and the fish cooks through gently inside, becoming opaque and flaky at the thickest part.

Spooning the salsa over the fish at the end of cooking takes advantage of the hot skillet. The salsa warms only briefly, so the mango stays fresh and the cilantro keeps its color, while the juices mingle with the pan butter. Because the salsa is added after the fish is cooked, the crust remains exposed on top, and the contrast between crisp coconut and cool, juicy fruit is preserved. Reducing the heat before adding the salsa prevents the coconut from scorching during this last stage.

Notes and substitutions

Mahi-mahi is the fish called for here, and its firm texture suits a coating and a quick sear. Choose fillets of similar thickness so they cook at the same pace. Cod, halibut or snapper are reasonable alternatives, though thinner fillets may need less time on each side.

Buy unsweetened shredded coconut rather than sweetened flakes, because the sugar burns quickly in the hot fat and changes the taste of the crust. Ripe mangoes give the best salsa; they should yield slightly to gentle pressure and smell fragrant at the stem.

A cast iron skillet is the ideal pan because it holds heat evenly and gives a deep, uniform golden color to the coconut. A nonstick or stainless steel skillet of similar size also works, but preheat it fully before adding the fat.

Use a shallow plate or board to spread the coconut, so the fillets can be pressed into it on both sides. Tongs or a fish spatula make the flip easy and protect the crust. Fresh lime is essential for both the salsa and the wedge on the side, because bottled juice lacks the brightness that the dish depends on.

• Mahi-mahi fillets: Cod, halibut or snapper fillets of similar thickness; cook until the flesh is opaque and flakes easily.
• Fresh mangoes: Thawed frozen mango cubes, drained well and diced, for a salsa that is slightly less bright.
• Unsalted butter: Ghee or additional neutral oil for a similar sizzle without milk solids.
