Can I use frozen mahi mahi for this recipe?

Absolutely! Just make sure it's completely thawed and patted very dry before seasoning and grilling. Frozen mahi mahi is often of excellent quality and more affordable than fresh, making it a practical choice for many home cooks.

How do I know when my fish is done without a thermometer?

The fish should turn from translucent to opaque white throughout. Take a fork and gently press into the thickest part - if it flakes easily and is no longer translucent, it's done. Be careful not to overcook, as mahi mahi can dry out quickly.

What's the best way to prevent fish from sticking to the grill?

Three key steps: make sure your grill is properly cleaned and preheated, oil both the grill grates and the fish itself, and don't try to flip the fish until it naturally releases from the grate. If it's sticking, it probably needs another minute before flipping.

Can I add a marinade to this recipe?

You certainly can, but keep marinating time short (15-30 minutes maximum) as the acid in most marinades can "cook" the fish before it hits the grill. A simple marinade of olive oil, lemon juice, garlic and herbs works wonderfully with mahi mahi.

How to Make Grilled Mahi Mahi

Step 1: Prep the Fish

Pat those fillets completely dry with paper towels – this is crucial for getting that perfect sear! Place them in a bowl, drizzle with olive oil, and season both sides generously with salt and pepper. The oil will help the seasonings stick and prevent the fish from sticking to the grill.

Step 2: Prepare Your Grill

Lightly grease your grill grates with olive oil or cooking spray. This extra step prevents sticking and makes flipping so much easier. Crank the heat up to high – you want those grates screaming hot for the perfect sear.

Step 3: Grill to Perfection

Place your seasoned fillets on the hot grill and let them cook undisturbed for 2-3 minutes. Resist the urge to move them around! When it’s time, flip them once and cook for another 3 minutes. You’ll know they’re done when the fish flakes easily with a fork and turns opaque, or reaches an internal temperature of 145°F.

Step 4: Finish and Serve

Remove your beautifully grilled fish from the heat, drizzle with fresh lemon juice, and sprinkle with parsley if using. Serve immediately while hot for the best flavor and texture.

Pro Tips for Making the Recipe

The Dry Factor: Don’t skip patting the fish dry – this single step is the difference between a perfect sear and a steamed, soggy fillet.
Hot Grill, Cold Fish: For best results, take your fish out of the refrigerator about 10 minutes before grilling so it’s not ice cold when it hits the heat.
The Flip Trick: Use a wide, thin spatula for turning, and only flip once! Each time you flip, you risk breaking the fillet.
Doneness Test: If you don’t have a thermometer, gently press the fish with your finger – it should be firm but still have a little give, and should flake when gentle pressure is applied.
Timing Matters: Mahi Mahi cooks quickly! Have your sides ready before you start grilling so you can serve everything at its peak.

How to Serve

Grilled Mahi Mahi pairs beautifully with so many sides and accompaniments:

Perfect Pairings:

Serve over a bed of coconut rice with a side of grilled pineapple for a tropical-inspired plate
Add a bright, acidic side like a tomato and cucumber salad to complement the rich fish
Go classic with grilled asparagus or roasted vegetables for a complete, healthy meal

Sauce Options:

A dollop of mango salsa adds color and sweet-spicy contrast
Lemon butter sauce if you’re feeling indulgent
Simple chimichurri sauce for an herbaceous kick

Make Ahead and Storage

Storing Leftovers

Store leftover mahi mahi in an airtight container in the refrigerator for up to 5 days. The clean flavors actually make excellent leftovers for lunch the next day!

Freezing

If you need to freeze your cooked mahi mahi, place the completely cooled fillets in an airtight, freezer-safe container. They’ll maintain good quality for up to two months.

Be sure to label with the date so you know when to use them by!

Reheating

For best results, reheat gently in a non-stick pan over medium-low heat with a splash of water to maintain moisture. Alternatively, wrap in foil and warm in a 300°F oven until just heated through (about 10 minutes). The microwave works in a pinch, but can dry out the fish, so use lower power and check frequently.
