Description

Quick and elegant, this broiled mahi mahi features flaky fish topped with a golden parmesan butter – perfect for an impromptu, restaurant-worthy dinner!


Ingredients

Units Scale

  • 1 1/2 lb mahi mahi fillets (4 6oz fillets)

  • kosher salt and black pepper

  • 2 tablespoons butter, softened to room temperature

  • 2 1/2 tablespoons mayo

  • 1oz parmesan cheese, grated (about 1/3 cup total)

  • lemon wedges, for serving


Instructions

  1. Arrange oven rack to the top third of the oven, usually about the second notch down. Preheat oven to 425°F (218°C). Line a large baking tray with a silicone baking mat or aluminum foil. Don’t use parchment paper, it will burn.
  2. Pat mahi mahi fillets dry with a paper towel and season each with generous pinches of salt and pepper all over. In a small bowl, smash together the softened butter, mayo and parmesan cheese until well combined.
  3. Divide butter mixture evenly between all fillets, about 1 ½ tablespoons per fillet, using your hands to spread it out to coat each piece of fish evenly. Bake mahi mahi for 5 minutes. Then switch the oven to broil for another 2-3 minutes until the fish is just cooked through. It should reach 140 °F. The top will be browned and bubbling and the fish should flake easily with a fork. Take care to not overcook!
  4. Serve hot with a squeeze of lemon and side dishes like balsamic asparagus and garlic bread! Balanced meal perfection.

Notes

Most mahi mahi fillets are pretty thin (mine were ½-inch) but if you do have a thicker cut of fish you might want to need to increase the initial roast time by 1-2 minutes.

My broiler is only one setting at 550 degrees F. If you have high and low settings, use whichever is closest to 550 degrees (this is mostly likely high). Remember, all ovens are different so keep an eye out!

I like to keep this recipe v simple with the butter and parmesan flavors shining through. But you can absolutely add a teaspoon or so of garlic powder, smoked paprika or your favorite seasoning to the parmesan butter mixture.
