Ingredients

Instructions

  1. Step 1: In a large saucepan, combine 2 cups coconut milk, 2 tbsp lemon myrtle leaves, 1 inch sliced fresh ginger, 2 minced garlic cloves, and 1 tsp sea salt. Bring to a gentle simmer over medium heat and cook for 10 minutes to infuse the flavors.
  2. Step 2: Remove the lemon myrtle leaves and ginger slices with a slotted spoon. Add 4 barramundi fillets to the simmering coconut broth and poach gently for 6-8 minutes, until the fish is opaque and flakes easily.
  3. Step 3: Stir in 2 tbsp fresh lime juice and 1/4 cup chopped fresh coriander leaves, then carefully ladle the broth and fish into warm bowls.
  4. Step 4: Garnish with 1 small sliced green chili if desired for a mild heat, and serve immediately with steamed jasmine rice or crusty bread to soak up the flavorful broth.

How do I store leftover Slow-Cooked Barramundi in Lemon Myrtle and Coconut Broth?

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 coconut milk from drying out.
