Instructions

  1. Step 1: In a small bowl, mix 2 tsp lemon myrtle powder, 1 tsp sea salt, 1/2 tsp black pepper, 2 tbsp olive oil, and 1 tbsp lemon juice to form a marinade.
  2. Step 2: Pat dry 4 barramundi fillets (6 oz each) and brush both sides evenly with the marinade. Let sit for 15 minutes at room temperature.
  3. Step 3: Preheat barbecue grill to medium-high heat (about 400°F). Oil the grates lightly to prevent sticking.
  4. Step 4: Place the fillets skin-side down on the grill and cook for 4-5 minutes without moving, until the skin is crisp and grill marks appear.
  5. Step 5: Carefully flip the fillets and grill for another 3-4 minutes until opaque and flaky.
  6. Step 6: Remove from grill and serve immediately with fresh lemon wedges for squeezing over the top.
