Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F (190°C). Pat dry 4 barramundi fillets and season both sides with 1 tsp salt and 1/2 tsp black pepper.
  2. Step 2: Place 1/2 cup all-purpose flour on a plate, 1 beaten egg in a shallow bowl, and 1 cup finely chopped macadamia nuts on another plate. Dredge each fillet first in flour, shaking off excess, then dip in egg, and finally press into macadamia nuts to coat evenly.
  3. Step 3: Heat 2 tbsp olive oil in a large ovenproof skillet over medium-high heat. Add the crusted fillets and sear for 2 minutes per side until golden.
  4. Step 4: Transfer skillet to oven and bake the fillets for 6-8 minutes until fish flakes easily with a fork.
  5. Step 5: Meanwhile, make the beurre blanc: In a small saucepan, combine 1/4 cup dry white wine and 1 minced shallot. Simmer over medium heat until reduced by half, about 5 minutes.
  6. Step 6: Lower heat to low and whisk in 4 tbsp unsalted butter, 2 tbsp heavy cream, 1/2 tsp lemon myrtle powder, and 1 tbsp lemon juice until sauce is smooth and slightly thickened.
  7. Step 7: Serve each barramundi fillet drizzled with lemon myrtle beurre blanc sauce.
