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.

Recipe Ingredients

  • 4 (4 ounce) fillets mahi mahi fillets
  • 1 cup Italian-style salad dressing
  • 1 pinch lemon-pepper seasoning, or to taste
  • garlic powder, or to taste
  • 4 raw onion rings
  • 1 lemon, quartered

Cooking Directions

  1. 1 Arrange 4 large pieces of aluminum foil on a work surface.
  2. 2 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.
  3. 3 Preheat oven to 325 degrees F (165 degrees C).
  4. 4 Bake in the preheated oven until fish flakes easily with a fork, about 30 minutes. Carefully open packets and remove onion before serving.

Chef's Notes

The nutrition data for this recipe includes the full amount of the marinade ingredients. The actual amount of the marinade consumed will vary.


  1. 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.
  2. Could have used more flavor but it was very tender. I would make it again.
  3. 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.
  4. 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.
  5. 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 - Read more ...
  6. I like fish a lot including Mahi Mahi but I expected a lot more from this recipe. Will not be making this one again.
