Directions

Preheat the grill to medium-high heat (around 400°F). Lightly oil the grates to prevent sticking.
In a small bowl, mix melted butter, minced garlic, lemon zest, lemon juice, paprika, oregano, salt, black pepper, and red pepper flakes.
Pat mahi mahi fillets dry with a paper towel and brush both sides with olive oil.
Place the fillets on the grill and cook for 3-4 minutes per side, or until the fish is opaque and easily flakes with a fork.
During the last minute of grilling, brush the fish generously with the lemon garlic butter sauce.
Remove from the grill and transfer to a serving plate. Drizzle any remaining sauce over the fillets and sprinkle with fresh parsley.
Serve hot with lemon wedges on the side.

10 Tips for Cooking This Dish

Use fresh mahi mahi for the best flavor and texture. Frozen can work, but thaw it properly before grilling.
Pat the fish dry before grilling to help achieve a nice sear.
Preheat the grill and oil the grates well to prevent sticking.
Don’t overcook the fish—mahi mahi should be opaque and flake easily when tested with a fork.
Use a meat thermometer: 137°F (58°C) is the perfect internal temperature.
Baste with garlic butter in the last minute of grilling for an extra burst of flavor.
Let the fish rest for a couple of minutes before serving to lock in the juices.
Enhance the flavor by marinating in lemon juice, olive oil, and herbs for 15 minutes before grilling.
If you don’t have a grill, you can use a grill pan or broil the fish in the oven.
Serve immediately with fresh lemon wedges to brighten the flavors even more.
