You are going to love this dish! So easy to prep, so easy to clean up after! It has all the feels and flavors of Hawaii. Delicious anytime of the year, but especially on these warm summer nights!


4 filets of firm white fish*

2 tablespoons softened butter

2 tablespoons mayonnaise

½ cup roasted salted macadamia nuts, finely chopped

Salt and Pepper

*I prefer to use Halibut or Mahi Mahi. Costco has amazing vacuum-sealed frozen Mahi and Halibut that, although frozen, work perfectly! Simply defrost frozen filets in the fridge for a few hours before cooking.


  1. Heat a cast iron skillet in the oven at 400°. (If you don’t have a skillet handy, a baking sheet with parchment works fine.)


  1. In a small bowl, combine soft butter and mayonnaise and mix well.


  1. Rinse fish and pat dry. Lightly season with salt and pepper. Spread the softened butter mixture over the top and sides of fish. Gently press on the chopped nuts to cover fish.

  1. Carefully remove preheated skillet from oven and set on a heat-proof counter or cooktop. Brush the skillet with some oil to prevent fish from sticking. Place the filets in the skillet, butter/mayo side up.


  1. Return skillet to the oven and bake for 15-20 minutes (depending on thickness of the filets). To check for doneness, simply use a fork in the center to gently pull apart the fish. Fish should flake and separate easily.

  1. Serve with steamed rice and fresh mango salsa (recipe below).


Mango Salsa – Combine the following:

  • 2 ripe mangoes, diced small
  • 1 scallion (white and green parts) finely chopped
  • ¼ cup finely chopped red onion
  • ¼ cup chopped tomatoes
  • ¼ cup cilantro, finely chopped
  • Optional ½ Serrano chili, seeded and finely chopped (substitute a milder chili if you prefer)
  • 1 lime, juiced
