Whole Branzino Roasted in Salt

This elegant whole roasted sea bass is a stunning choice for a healthy dinner party or a light weekend meal. Encasing the fish in a coarse salt crust creates a natural oven, sealing in moisture and infusing the flesh with a subtle, seasoned flavour without making it overly salty. It is a classic Mediterranean technique that produces perfectly flaky, succulent results every time.

As a diabetes-friendly main course, this dish is naturally low in carbohydrates and rich in heart-healthy omega-3 fatty acids. The fresh salsa verde, made with crunchy celery, cucumber, and briny capers, provides a vibrant contrast to the delicate fish. Serve this impressive seafood centrepiece with the peppery rocket salad for a nutritious, restaurant-quality meal that is remarkably simple to prepare at home.

How to make Whole Branzino Roasted in Salt

Preheat oven to 204°C. Stir salt and 5 egg whites in large bowl, adding more egg whites as needed to form grainy paste. Press 1/4-inch layer of salt mixture (large enough to hold both fish) onto large rimmed baking sheet. Stuff cavity of each whole fish with half of herb sprigs and lemon slices. Place fish atop salt mixture on baking sheet. Pack remaining salt mixture over fish to enclose completely. Roast until thermometer inserted into thickest part of fish registers 57°C, about 20 minutes. Let stand 10 minutes.

Using small sharp knife, remove peel and white pith from lemon. Working over bowl, cut between membranes to release segments. Cut each segment into 3 pieces. Add lemon pieces and next 6 ingredients to bowl.

Using back of large spoon, gently crack open salt crust on fish. Lift and discard salt layer. Pull skin from top of 1 fish. Carefully lift top fillet from bones and transfer to plate. Lift and discard bones. Gently lift second fillet from skin and transfer to second plate. Repeat with second fish for a total of 4 plates.

Spoon salsa verde over fish, leaving juices in bowl. Add rocket to bowl; toss to coat. Divide among plates.
