Ingredients

Instructions

  1. Step 1: In a small bowl, combine 1/2 cup finely chopped macadamia nuts, 1/4 cup panko breadcrumbs, and 2 tbsp chopped fresh parsley.
  2. Step 2: Pat dry 4 barramundi fillets and season both sides with 1 tsp sea salt and 1/2 tsp black pepper.
  3. Step 3: Heat 2 tbsp olive oil in a large non-stick skillet over medium heat (around 350°F). Sear the fillets skin-side down for 3 minutes until crispy.
  4. Step 4: Flip the fillets and press the macadamia nut mixture firmly onto the flesh side of each fillet. Cook for another 3 minutes until the crust is golden and fish is cooked through.
  5. Step 5: In a separate small pan, melt 4 tbsp unsalted butter over low heat. Add 3 tbsp fresh lemon juice and stir for 1 minute until the sauce slightly thickens.
  6. Step 6: Plate the barramundi fillets crust side up and drizzle with the warm lemon butter sauce before serving.
