Serves: 4
  • 1 Tablespoon coconut oil, melted
  • 1 lb. Rockfish (about 2 large fillets)
  • Blackened Seasoning:
  • 1 Tablespoon paprika
  • 1 teaspoon cayenne pepper
  • ½ teaspoon garlic powder
  • 1 teaspoon of dried thyme leaves
  • 1 teaspoon of dried oregano leaves
  • ½ teaspoon salt
  • ½ teaspoon ground black pepper
  • Avocado Fish Taco Sauce:
  • 1 avocado
  • ½ cup non-fat Greek yogurt
  • 1 cup of water
  • 2 cups of cilantro with stems
  • ½ lime juice
  • 1 large garlic clove
  • ½ teaspoon salt (I use Himalayan)
  • 1-2 splashes of chipotle sauce (optional)


  • Paprika
  • Cayenne Pepper
  • Garlic Powder
  • Salt and Pepper
  • Herbs: Thyme and Oregano, dried


  1. Make the rub by mixing cayenne pepper, salt, pepper, thyme, oregano, garlic powder and paprika. Set aside until ready to rub all over that delicious fish!
  2. Put fish in a pan and sprinkle your blackened mixture on top. Using your fingers rub it in all around the top and sides.
  3. Broil the blackened rockfish high for about 6-10 minutes depending on the thickness of the meat.
  1. Blend all ingredients of the avocado fish taco sauce in a blender. Set aside in the refrigerator until ready to use.
  2. In a small bowl mix all the ingredients for the blackened seasoning. Set aside.
  3. Preheat the oven to Broil. In a baking dish drizzle 1 tablespoon of coconut oil and add the Rockfish. Pour blackened seasoning on top of the fish and using hands rub it into the fish and around the sides. Bake uncovered 6-10 minutes or until the center is cooked and flakes apart when pulled with a fork (bake 6 minutes for thin slices, thick slices might need about 10 minutes). If it starts to burn on top cover in foil.
  4. Drizzle the avocado fish taco sauce on top. Serve with a side of vegetables and rice.
