Cashew Crusted Halibut Recipe and Mango Sauce

Prep Time 10 minutes
Cook Time 10 minutes
Total Time 20 minutes


Cashew Crusted Halibut

  • 1 lb halibut fillet
  • 1 cup raw cashew nuts crushed
  • 1 tsp fresh thyme
  • 1 tbsp fresh chopped parsley
  • avocado oil spray
  • Salt and pepper to taste

Mango Butter Sauce

  • 1 ripe mango peeled & cut
  • 1/4 cup ghee
  • 1/4 cup water
  • Pinch of Himalayan salt


  • PREHEAT the oven to 400 degrees.
  • MAKE the crust by putting the cashew nuts in a plastic bag, then use a mallet or rolling pin to crush them finely. Pour the crushed cashews onto a plate, add thyme, parsley, salt, & pepper, and set aside.
  • PAT halibut dry with a paper towel, then season both sides with salt and pepper.
  • DIP the halibut into the cashew mixture to coat the top of the halibut. Spray a sheet pan with avocado oil, add your cashew-crusted halibut, then give the tops a light spray as well.
  • BAKE halibut at 400 degrees for 7-10 minutes.
  • MAKE the mango butter sauce while the halibut is baking by adding the chopped mango, ghee, water, and Himalayan salt to a small pot.
  • BRING to a boil and let simmer for 2 minutes. Let cool for 2 minutes, then add the mixture to a blender and blend into a smooth consistency. If the sauce is too thick, add a teaspoon of water and blend again.
  • SPOON the mango butter on a plate, creating a circle larger than the halibut. Remove halibut from the oven and place on top of the sauce and serve with your favorite vegetables.
  • ENJOY!
