Blackened mahi mahi is a quick fish dinner made with mahi mahi fillets, Cajun seasoning, butter, and a hot skillet. The fish develops a flavorful dark crust while staying moist and flaky inside.
1poundskinless mahi mahi fillets(figure 6-8 ounces per person)
1tablespoonCajun blackened seasoning
1tablespoonvegetable oil
2tablespoonsunsalted butter,melted
kosher salt and freshly ground black pepper
1lemon,sliced into wedges
Instructions
If frozen, thaw the mahi mahi completely and pat dry with paper towels.
Let the fish sit at room temperature for about 15 minutes before cooking.
Brush the fish lightly with melted butter, then coat both sides with blackened seasoning.
Heat a heavy-bottomed stainless steel or cast iron skillet over medium-high heat until very hot.
Add the vegetable oil to the skillet and swirl to coat.
Place the fish in the pan and cook for 3 to 4 minutes per side, depending on thickness, until a dark crust forms.
The fish is done when it flakes easily with a fork and reaches 145°F internally.
Serve immediately with lemon wedges.
