Roast Side of Salmon with Mustard, Tarragon, and Chive Sauce

This roast side of salmon with mustard, tarragon, and chive sauce is a sophisticated yet deceptively simple centrepiece. Combining the punchy heat of brown mustard with the aromatic sweetness of fresh tarragon and chives, the glaze creates a vibrant crust that keeps the fish incredibly succulent. It is a fantastic choice for a celebratory lunch or a light dinner, offering a beautiful balance of rich omega-3 fatty acids and bright, zesty citrus flavours.

As a heart-healthy main course, this dish focuses on high-quality protein and fresh herbs rather than heavy fats. The salmon side cooks remarkably quickly at a high temperature, ensuring a tender finish every time. Serve it alongside some steamed seasonal greens and crushed new potatoes for a balanced, nutritious meal that feels truly indulgent without the fuss.
