Pat the fish fillets dry with paper towels. Coat them all over with the olive oil mixture.
3 Mahi Mahi fillets
Heat a gas grill, an electric grill, or a stovetop grill pan to medium-high.
Place the fish on the grill. Brush their tops with any remaining marinade. Grill the fish until cooked through, about four minutes on the first side and three more minutes on the second. Lower the heat to medium if your grill becomes too hot.
Serve immediately, garnished (if desired) with lemon slices and chopped cilantro.
1 lemon, 2 tablespoons cilantro

Notes
Seasonings, especially salt, are guidelines - adjust to taste.
The fish is ready when its internal temperature reaches 145°F. It should have a firm, opaque flesh that easily flakes with a fork.
You can make this recipe successfully with other white fish, such as cod or halibut, as long as they are about ½-inch thick.
I typically use a stovetop grill pan that accommodates three fillets, and this recipe reflects that. If your grill has more space, you can cook more fillets and adjust the remaining ingredients accordingly.
To pan-fry this fish, season the fillets with salt, pepper, and garlic powder. Heat 3 tablespoons of butter in a nonstick skillet over medium heat. Add the fish and cook until cooked through, 3-4 minutes per side. Transfer the fish to plates and drizzle the pan sauce on top.
To bake this fish, place the seasoned fillets on a parchment-lined, rimmed baking sheet and bake them uncovered for about 15 minutes in a preheated 425°F oven. There's no need to flip them. Check with a thermometer that they have reached 145°F.
You can keep the leftovers in an airtight container in the fridge for up to three days. Reheat them in the microwave covered, or flake them and use them cold as a salad topping.
