This salt-baked salmon with citrus and herbs is a spectacular centrepiece that delivers incredibly moist, perfectly seasoned fish every time. The salt crust acts as a natural oven, insulating the salmon and locking in the aromatic flavours of tarragon, dill, grapefruit, and lemon. This traditional cooking method not only ensures a succulent texture but also provides a theatrical moment at the dinner table when the crust is cracked open to reveal the steaming, fragrant fish beneath.
As a sophisticated high-protein main course, this dish is ideal for weekend entertaining or special family gatherings. The richness of the salmon is beautifully balanced by a velvety citrus beurre blanc and a punchy herb salad featuring capers and caraway seeds. Ask your fishmonger for a whole, cleaned fish to make preparation effortless, and serve with steamed seasonal greens for a complete, nutritious meal.

How to make Salt-Baked Salmon with Citrus and Herbs
Back to contentsPlace a rack in the centre of oven and preheat to 400°. Season inside of salmon with salt. Stuff with one-third of grapefruit slices, lemon slices, dill sprigs, and tarragon sprigs.
Mix 2400ml salt and 350ml water in a large bowl, adding more water as needed, until mixture is the texture of wet sand. Spread a thin layer of salt mixture on a rimmed baking sheet roughly the same shape and size as fish.
Top salt mixture with another third of grapefruit and lemon slices and dill and tarragon sprigs; set salmon on salt bed and top with remaining citrus and herbs. Pack remaining salt mixture over fish, leaving head and tail peeking out.
Roast salmon until just cooked through (poke a paring knife or metal skewer though the salt and into the flesh; it should feel warm to the touch when removed), 40–50 minutes.
While salmon is cooking, simmer shallot and wine in a small saucepan until only 2 tablespoons liquid remains, 8–10 minutes. Whisking constantly, add butter a piece at a time, incorporating completely before adding the next piece, to make a glossy, emulsified sauce.
Whisk crème fraîche, grapefruit zest, grapefruit juice, lemon zest, and 1 teaspoon lemon juice into sauce; season with salt. Reduce heat to low and keep sauce warm while you finish the dish.
Remove salmon from oven and using a knife or the edge of a fish spatula, crack salt crust and remove (it should come off in large pieces); let salmon sit 5 minutes before serving.
Meanwhile, toss parsley, dill, tarragon, capers, caraway seeds, and remaining 2 teaspoons lemon juice in a medium bowl; season herb salad with salt. Serve salmon with beurre blanc and herb salad.
