Ingredients

Instructions

  1. Step 1: Preheat oven to 275°F (135°C). Place 4 barramundi fillets (5 oz each) on a rimmed baking tray lined with parchment paper. Drizzle evenly with 2 tbsp olive oil, then season with 1 tsp sea salt, 1/2 tsp black pepper, and 1 tsp lemon zest.
  2. Step 2: Slow roast the fillets in the oven for 20-25 minutes until the fish is opaque, flakes easily, and remains moist.
  3. Step 3: While the fish roasts, combine the pulp of 3 finger limes, 1 small finely diced red chili, 2 tbsp chopped fresh coriander leaves, and 1 tbsp fresh lemon juice in a small bowl. Mix gently to create a vibrant citrus salsa.
  4. Step 4: Remove the barramundi from the oven and spoon the finger lime salsa over each fillet. Serve immediately with steamed jasmine rice or sautéed greens.
