- Step 1
Preheat oven to 220C/200C fan-forced. Line a large baking tray with baking paper.
- Step 2
Place vegetables on prepared tray. Drizzle with 1 tablespoon oil. Season with salt and pepper. Toss to coat. Bake for 12 minutes.
- Step 3
Meanwhile, heat a large non-stick frying pan over high heat. Add fish, skin-side down. Cook for 2 minutes or until skin is very crispy around edges and centre is just starting to crisp. Place fish, skin-side up, on top of vegetables on tray. Bake for 4 minutes or until fish is just cooked through and vegetables are tender.
- Step 4
Heat remaining oil in a small saucepan over medium heat. Add garlic. Cook, stirring, for 1 minute or until fragrant (do not brown). Add chives and parsley. Cook for 1 minute. Remove pan from heat. Add lemon zest and juice. Season with salt and pepper.
- Step 5
Serve barramundi and vegetables drizzled with warm garlic and herb oil.
To score barramundi skin, use a large sharp knife to make shallow cuts crossways, about 1cm apart, along the length of each fillet. This will help prevent the fillet from curling up while cooking.
