Ingredients

Instructions

  1. Step 1: Season 4 barramundi fillets evenly with 1 tsp salt and 1/2 tsp freshly ground black pepper on both sides.
  2. Step 2: Heat 2 tbsp olive oil in a large non-stick skillet over medium-high heat until shimmering. Place fillets skin-side down and cook without moving for 4-5 minutes until the skin is crisp and golden.
  3. Step 3: Carefully flip the fillets and cook for an additional 2-3 minutes until the flesh is opaque and flakes easily with a fork.
  4. Step 4: While fish cooks, mix 4 tbsp softened unsalted butter with 1 tsp finely grated lemon zest, 1 tbsp lemon juice, 1 tsp ground wattleseed, and 1 tbsp finely chopped fresh parsley until well combined.
  5. Step 5: Remove the fillets from heat, place on serving plates, and top each with a dollop of the lemon wattleseed butter, allowing it to melt over the warm fish before serving.

How do I store leftover Barramundi Fillets Pan-Seared with Lemon Wattleseed Butter?

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 Barramundi Fillets Pan-Seared with Lemon Wattleseed Butter?

How do I scale Barramundi Fillets Pan-Seared with Lemon Wattleseed Butter for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
