This quick and easy grilled mahi mahi is infused with bold, Asian-inspired flavors thanks to a simple marinade of coconut aminos, toasted sesame oil, and sweet chili sauce. Light, flavorful, and perfect for summer grilling!

As a dietitian, I’m always looking for meals that check all the boxes—nutritious, simple to prepare, and family-approved. This mahi mahi recipe is one of my favorites because it’s packed with protein, heart-healthy fats, and fresh flavors. Even my teenager, who isn’t usually a big fan of fish, cleans his plate every time we have it!

This recipe is quick enough for a busy weeknight but feels special enough for a weekend dinner. Plus, it pairs beautifully with a variety of whole grains and vegetables to create a balanced, Mediterranean-inspired plate.

Why Mahi Mahi is so Good for You

Mahi mahi is a lean, high-quality protein source with about 20 grams of protein per 3-ounce serving—perfect for supporting muscle health, keeping you full longer, and balancing blood sugar.

It’s also rich in:

Vitamin B12 – essential for energy and nervous system health
Selenium – a powerful antioxidant that supports thyroid and immune function
Omega-3 fatty acids – anti-inflammatory fats that promote heart and brain health

This recipe isn’t just about the fish—the flavorful marinade brings its own nutrition benefits:

Toasted Sesame Oil – Provides healthy unsaturated fats and antioxidants like sesamol and sesamin, which have anti-inflammatory and heart-protective properties. Its rich, nutty flavor goes a long way, so you get big taste with a small amount.

Coconut Aminos – A lower sodium alternative to soy sauce, coconut aminos adds a slightly sweet, umami flavor without the gluten or excessive salt. It also contains small amounts of amino acids and antioxidants.

Sweet Chili Sauce – While it does contain some natural sugars for sweetness, sweet chili sauce adds a flavorful punch with red chili peppers, rich in capsaicin, a compound with metabolism-boosting and anti-inflammatory properties. Sweet chili sauce provides just the right amount of zest without overpowering the dish.

Together, these ingredients create a marinade that’s both nourishing and delicious—proof that healthy eating doesn’t have to be bland!

Tips for Making the Tastiest Mahi Mahi

Pat the fish dry before seasoning to help get a golden crust.
Use a hot grill or skillet to sear and lock in moisture.
Don’t overcook it. Mahi mahi is done when it flakes easily with a fork and turns opaque or when a meat thermometer reads about 135 degrees Fahrenheit. Overcooking will cause dry fish.

What to Serve with Mahi Mahi for a Balanced Meal

To build a nourishing plate, I recommend:

Starch (1/4 of your plate):

Quinoa, farro, or wild rice for a fiber-rich, satisfying base
Roasted sweet potatoes for a hint of natural sweetness
Baked potato

Non-starchy veggies (1/2 of your plate):

Garlic-sautéed spinach or kale
Roasted asparagus, broccoli, or Brussels sprouts
A fresh cabbage slaw with olive oil and vinegar
Crisp cucumber salad or side salad

Healthy fats- the sesame oil in the marinade provides plenty of added fat but if you are looking for a higher fat intake try one of these options:

A spoonful of avocado or olive tapenade
A sprinkle of toasted sesame seeds or chopped cashews- place on top of the mahi mahi just before serving. The sesame seeds would complement the toasted sesame oil in the recipe and add a nutty crunch, while cashews pair beautifully with the sweet chili and coconut aminos for a Thai-inspired flavor. Both options provide healthy fats and a boost of texture to the dish.

This combination provides protein, fiber, and healthy fats to keep you feeling full and energized—just what we’re looking for in a Mediterranean and anti-inflammatory lifestyle.
