Ingredients and Variations

THE MARINADE: This is a simple marinade made with some soy sauce, oil, lime juice, garlic, sesame oil, and ginger. It’s so easy and full of delicious flavor and taste.

THE FISH:  If fresh mahi-mahi is difficult to find, look in the freezer section for frozen fillets. And purchase fish that has already been filleted because this will make prep and cooking easier.

How To Bake Mahi Mahi

  1. Combine the marinade ingredients in a bowl.
  2. Add fish to the marinade. Refrigerate.
  3. Place fillets in a baking dish and discard marinade.
  4. Bake. (As per recipe below)

How Long To Bake Mahi Mahi

It is important to make sure that the temperature is correct, and to cook mahi mahi for the exact time indicated (as per recipe below). Use a meat thermometer for a precise temperature reading to ensure moist and flaky fish.

Perfect Mahi Mahi

If using frozen mahi-mahi, make sure that it is completely thawed before cooking. If fish is still a bit frozen, the edges could dry out before the center is cooked through.

Always marinate any seafood in the refrigerator and not on the counter.

    1. So sorry that happened, Mary! To avoid overcooking we recommend letting it marinate for the full hour in the refrigerator and to check the internal temperature at 12 minutes or even sooner if your oven runs hot. Hope that helps!

    Wow, the fish turned out fantastic. I used toasted sesame oil instead and baked the fish for about 10 min in the half oven. Thank you so much for posting this recipe.
