Ingredients

Instructions

  1. Step 1: Season 4 barramundi fillets with 1 tsp salt and 1/2 tsp black pepper. Set up three shallow plates: one with 1/2 cup all-purpose flour, one with 2 beaten eggs, and one with 1 cup finely chopped macadamia nuts.
  2. Step 2: Dredge each fillet first in the flour, shaking off excess, then dip into the beaten eggs, and finally press into the macadamia nuts to coat evenly.
  3. Step 3: Heat 3 tbsp olive oil in a large non-stick skillet over medium heat. Add the coated barramundi fillets and cook for 4-5 minutes per side until golden brown and cooked through.
  4. Step 4: While the fish cooks, combine 1/2 cup heavy cream, 1 tsp lemon myrtle powder, 2 tbsp lemon juice, and 1 minced garlic clove in a small saucepan. Heat over low heat for 3-4 minutes, stirring gently until warmed and slightly thickened.
  5. Step 5: Plate the barramundi and spoon the lemon myrtle sauce over the top before serving.
