• Fish Swap: This recipe works beautifully with other firm white fish like swordfish, tuna, or halibut.

How to Make Grilled Mahi Mahi

Step 1: Prep the Fish

Place your Mahi Mahi fillets on a sheet tray and brush all sides thoroughly with olive oil. This step is crucial – the oil helps the seasonings stick and prevents the fish from sticking to the grill.

Step 2: Season Generously

In a small bowl, mix together the salt, garlic powder, onion powder, smoked paprika, and black pepper. Don’t be shy – season the fish well on the top and sides, then gently rub the seasonings into the flesh. This creates that perfect flavor-packed crust.

Step 3: Prepare Your Grill

Heat your grill to medium-high and thoroughly oil the grates. This double protection (oiled fish and oiled grates) ensures your beautiful fillets won’t stick and fall apart.

Step 4: Grill to Perfection

Place the fish flesh-side down on the hot grill. Let it cook undisturbed for 3-5 minutes – resist the urge to move it around! Carefully flip once and cook the other side until it reaches your desired doneness. For perfectly cooked fish, look for an internal temperature of 165°F.

Step 5: Finish with Butter

As soon as you remove the fish from the grill, brush the tops with melted butter. This creates a glossy, flavorful finish that takes the dish to another level. Garnish with fresh parsley if desired, and serve with lemon wedges for squeezing.

Pro Tips for Making the Recipe

• Don’t Overcook: Mahi Mahi cooks quickly and continues cooking a bit after you remove it from the heat. It’s better to slightly undercook than overcook.
• Room Temperature Fish: Let your fillets sit out for 15 minutes before grilling for more even cooking.
• The Flip Technique: Use a thin, wide fish spatula and be decisive with your flip – hesitation leads to sticking.
• Watch for Visual Cues: The fish will change from translucent to opaque as it cooks, moving upward from the bottom. Flip when it’s about halfway up the side.
• Let It Rest: Give the fish a minute or two after grilling before serving to allow the juices to redistribute.

How to Serve

This perfectly grilled Mahi Mahi is incredibly versatile and pairs beautifully with numerous sides:

Light and Fresh

Serve over a bed of mixed greens with a citrus vinaigrette, or with a cucumber-tomato salad for a light lunch.

Hearty Dinner

Pair with grilled asparagus and lemon herb rice or roasted garlic mashed potatoes for a more substantial meal.

Taco Night

Flake the grilled fish and serve in warm tortillas with cabbage slaw, avocado, and a squeeze of lime for fantastic fish tacos.

Make Ahead and Storage

Storing Leftovers

Cooked Mahi Mahi will keep in an airtight container in the refrigerator for up to 2 days. The texture is best enjoyed fresh, but leftovers are still delicious.

Meal Prep

You can prep the spice mixture in advance and store it in an airtight container. The fish itself is best seasoned just before cooking for optimal flavor and texture.

Reheating

For the best texture, reheat leftover fish gently. Place it in a 275°F oven covered with foil until just warmed through (about 10 minutes), or microwave at 50% power in short intervals to prevent drying out.

FAQs

How do I know when my Mahi Mahi is done cooking?
Perfectly cooked Mahi Mahi will be opaque throughout and flake easily with a fork. If you’re using a thermometer, aim for 145°F for medium or 165°F for well-done. Remember that the fish will continue cooking slightly after removing from the grill, so it’s better to pull it slightly early than late.

Can I make this recipe if I don’t have a grill?
Absolutely! A grill pan on the stove works beautifully, or you can broil the fish for similar results. For broiling, place the seasoned fish on a lined baking sheet, position it about 4 inches from the heating element, and cook for about 4 minutes per side, watching carefully to prevent burning.

What’s the best way to prevent fish from sticking to the grill?
The triple approach works best: 1) Make sure your grill is very hot before adding the fish, 2) Oil the grates well, and 3) Ensure the fish itself is brushed with oil. Another trick is to let the fish cook undisturbed until it naturally releases from the grate – if you try to flip too soon, it will stick.

Can I use frozen Mahi Mahi for this recipe?
Yes, but be sure to thaw it completely in the refrigerator overnight and pat it very dry with paper towels before oiling and seasoning. Excess moisture is the enemy of good grill marks and proper browning.
