It was my first time baking mahi mahi with lemon pepper seasoning, and it was delicious. The amount of seasoning used is optional and personal preference, as is the length of time you let it marinate.

Instructions Checklist

  • Place 1 mahi mahi fillet onto each aluminum foil piece. Pour Italian dressing over each fillet. Sprinkle each fillet with lemon-pepper seasoning and garlic powder; flip fillets and season other side with lemon-pepper seasoning and garlic powder. Place 1 onion ring atop each fillet and squeeze lemon quarter over each fillet. Fold aluminum foil over each fillet, crimping all the corners to completely seal. Place packets in a glass baking dish in the refrigerator to marinate, about 2 hours.

  • Preheat oven to 325 degrees F (165 degrees C).

  • Bake in the preheated oven until fish flakes easily with a fork, about 30 minutes. Carefully open packets and remove onion before serving.

Not bad. Something to remember: Mahi Mahi is a very mild white fish that has almost no flavoring whatsoever (in my opinion at least) so it's going to turn out flavorless unless there is seasoning that is strong. I didn't think there was even close to enough lemon pepper seasoning in this recipe to help it along so I added about a tablespoon of that and increased the lemon juice to closer to 2 lemons worth and sprinkled Parmesan cheese on the fillets before baking. I also marinated for about 24 hours turning occasionally to make sure it was coated. Something I also tend to forget when I'm making thicker fillets: fish can cook better at higher temps so when 350 wasn't cutting it after a half hour I jacked up the heat to 425 for 20 minutes and it was cooked. This turned out relatively well but for a flavor that our household liked it needed some zing. If you have a household that isn't so sold on flavor (they salt things to death use ketchup no matter what it is...) the original recipe will work just fine. It just needed a bit more for us but all in all a decent starting point. Thanks for the recipe! Read More

The flavor of this fish was great BUT after almost an hour per directions in foil/325 oven the fish were still cold. We finished then on the stovetop and the result was delicious. Read More

I made this recipe with double the ingredients and slivers of cold butter. I baked each filet in its own foil on a baking sheet on 400 for 40 minutes. They turned out perfectly. I served each filet still in the foil like a boat and everyone loved dipping the fish in the sauce. Read More

It wasn't bad. I've used Olive Garden Italian salad dressing. I had trouble with forming an onion ring and used part of the onion. Not a bad fan of lemons but it came out okay. I've paired it with French fries. Read More
