Ingredients

Instructions

  1. Step 1: Pat dry 4 barramundi fillets and season both sides with 1 tsp salt and 1/2 tsp black pepper.
  2. Step 2: Heat 2 tbsp olive oil in a large nonstick skillet over medium-high heat. Place fillets skin-side down and cook for 4-5 minutes until skin is crisp and golden, then carefully flip and cook for 2 more minutes until fish is opaque.

  4. Step 4: Pour in 1/3 cup dry white wine and 2 tbsp white wine vinegar, simmer until reduced by half, about 3-4 minutes.
  5. Step 5: Lower heat to medium-low and whisk in 6 tbsp cold cubed unsalted butter, one piece at a time, until sauce is smooth and creamy.
  6. Step 6: Stir in 1 tsp lemon myrtle powder and 1 tbsp fresh lemon juice, adjust seasoning if needed.
  7. Step 7: Spoon the lemon myrtle beurre blanc over the barramundi fillets and garnish with 1 tbsp chopped fresh parsley before serving.

How do I store leftover Pan-Seared Barramundi with Lemon Myrtle Beurre Blanc?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep salt from drying out.

Can I substitute ingredients in Pan-Seared Barramundi with Lemon Myrtle Beurre Blanc?
