Instructions

  1. Step 1: In a shallow dish, combine 3/4 cup chopped macadamia nuts and 1/2 cup panko breadcrumbs. Season 4 barramundi fillets with 1 tsp sea salt and 1/2 tsp black pepper.
  2. Step 2: Press the top side of each fillet firmly into the nut and breadcrumb mixture to coat completely.
  3. Step 3: Heat 2 tbsp olive oil and 2 tbsp unsalted butter in a large non-stick skillet over medium-high heat until butter foams.
  4. Step 4: Place the fillets nut-side down in the skillet and cook for 4-5 minutes until the crust is golden and crisp.
  5. Step 5: Carefully flip the fillets and cook the other side for 3-4 minutes until the fish flakes easily with a fork.
  6. Step 6: Remove fillets from pan and keep warm. Lower heat to medium and add remaining 2 tbsp butter and 2 minced garlic cloves to the skillet. Cook 1 minute until fragrant.
  7. Step 7: Stir in 2 tbsp fresh lemon juice and 2 tbsp chopped fresh parsley, scraping any browned bits from the pan to create a sauce.
  8. Step 8: Spoon the lemon butter sauce over the fillets and serve immediately.
