Barramundi Fillets with Roasted Sweet Potatoes and Brussels Sprout Chips

This elegant barramundi dish is a fantastic choice for a high-protein dinner that feels truly special. The mild, buttery flavour of the white fish is perfectly complemented by a vibrant lime and shallot vinaigrette, while the velvety sweet potato mash provides a comforting, subtly spiced base. By roasting the Brussels sprout leaves separately, you create delicate, savoury crisps that add a wonderful textural contrast to the soft fish and mash.

Ideal for a nutritious mid-week meal or an impressive weekend dinner, this recipe balances wholesome ingredients with sophisticated techniques like butter-basting. Barramundi is an excellent source of lean protein and heart-healthy omega-3 fatty acids, making this a nourishing yet indulgent-tasting main course. Serve it alongside a chilled glass of Pinot Gris for a complete restaurant-style experience at home.

Ingredients for Barramundi Fillets with Roasted Sweet Potatoes and Brussels Sprout Chips

  • 1 small shallot, minced (about 30ml )

  • 3 teaspoons fresh lime juice, divided

  • 1 1/4 teaspoons finely grated lime peel

  • 1 teaspoon white wine vinegar

  • 1/2 teaspoons honey

  • 80ml extra-virgin olive oil, divided

  • 800g red-skinned sweet potatoes (yams)

  • 5 tablespoons unsalted butter, room temperature, divided

  • 1 teaspoon chopped fresh thyme

  • Pinch of freshly grated nutmeg

  • 1/4 cup warm whole milk

  • 230g brussels sprouts, leaves separated, cores discarded

  • 4 5-to 170g barramundi fillets

Whisk shallot, 1 teaspoon lime juice, lime peel, vinegar, and honey in small bowl. Whisk in 2 tablespoons oil. Season vinaigrette to taste with salt.

Preheat oven to 232°C. Pierce sweet potatoes in several places with fork. Place on sheet of aluminum foil and roast 30 minutes. Turn potatoes over and roast until soft, about 20 minutes longer. Let stand until cool enough to handle. Scoop flesh into processor; discard skins. Puree sweet potatoes until smooth. Add 3 tablespoons butter, thyme, nutmeg, and remaining 2 teaspoons lime juice; process until blended and smooth. Add milk; process to blend. Transfer to microwave-safe bowl. Season to taste with salt and pepper. DO AHEAD: Vinaigrette and potatoes can be made 1 day ahead. Cover separately and chill. Bring vinaigrette to room temperature and rewhisk before using.

Preheat oven to 232°C. Place brussels sprout leaves on rimmed baking sheet. Drizzle with 1 tablespoon oil, sprinkle with salt and pepper, and toss to coat. Spread leaves out in even layer. Roast until almost all leaves are brown in spots and crisp, tossing occasionally, about 15 minutes.

Meanwhile, heat remaining 2 tablespoons oil in heavy large skillet over medium-high heat. Sprinkle fish with salt and pepper. Add to skillet and cook 30 seconds. Reduce heat to medium and add remaining 2 tablespoons butter to skillet. Continue to cook fish until edges appear opaque, occasionally basting by spooning juices in skillet over, about 4 minutes. Turn fish over. Cook until just opaque in centre, about 2 minutes.

Rewarm sweet potatoes in microwave in 30-second intervals until heated through, stirring occasionally. Divide sweet potatoes among plates. Arrange fish alongside and drizzle vinaigrette over. Sprinkle brussels sprout chips over and serve.
