Ingredients

Instructions

  1. Step 1: Season 4 barramundi fillets with 1 tsp salt and 1/2 tsp black pepper. Dredge each fillet first in 1/2 cup all-purpose flour, then dip into 1 beaten egg, and finally press into 1 cup finely chopped macadamia nuts to coat evenly.
  2. Step 2: Heat 2 tbsp olive oil and 2 tbsp butter in a large skillet over medium heat until melted and shimmering. Add the coated barramundi fillets and cook for 4-5 minutes on each side until the crust is golden and the fish flakes easily.
  3. Step 3: Remove fillets from the skillet and keep warm. In the same skillet, reduce heat to low and add 1/2 cup heavy cream, 1 tsp lemon myrtle powder, and 2 tbsp lemon juice. Stir continuously until the sauce thickens slightly and is fragrant, about 2-3 minutes.
  4. Step 4: Spoon the lemon myrtle cream sauce over the barramundi fillets and serve immediately.

Frequently asked questions

How do I store leftover Macadamia-Crusted Barramundi with Lemon Myrtle Sauce?

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 finely chopped macadamia nuts from drying out.

Can I substitute ingredients in Macadamia-Crusted Barramundi with Lemon Myrtle Sauce?
