Best for: Small dinner parties and anyone who loves a little theatre — the crust is cracked open right at the table.
A whole fish sealed inside a hard shell of salt sounds like a magic trick, but it’s one of the oldest ways to cook fish around the Mediterranean, and the grill takes to it beautifully. The crust does three jobs at once: it seasons the fish gently, it seals in every bit of steam so the flesh stays silky, and it turns the serving into a small ceremony — carry the pan to the table, crack the shell, and lift it away to reveal a perfect whole fish. Ask the fish counter to scale and gut the branzino for you, and dinner is mostly salt, heat, and timing.
Grill: Indirect, medium-high heat (about 400–425°F), lid closed. Equipment: Rimmed cast-iron skillet or foil-lined sheet pan, instant-read thermometer. Course: Main dish.
Ingredients
Rest: 10 minutes. Total: 55 minutes.
- 1 whole branzino or sea bass (1 1/2–2 pounds), scaled and gutted
- 3 cups kosher salt
- 3 large egg whites
- 2 tablespoons water
- 4 lemon slices
- 4 sprigs dill or fennel fronds
- 2 garlic cloves, smashed
- 1 tablespoon olive oil
- 1/2 teaspoon black pepper
- Extra-virgin olive oil and lemon wedges, for serving
Directions
Prep and stuff the fish. Set up the grill for indirect cooking at medium-high heat, about 400–425°F. Pat the fish dry inside and out. Rub the cavity with the olive oil and black pepper, then stuff it with the lemon slices, dill, and garlic.
Whisk the crust mixture. Whisk the kosher salt, egg whites, and water together in a large bowl until the mixture feels like damp sand that holds together when you squeeze it.
Build the salt shell. Spread a bed of the salt mixture about 1/2 inch thick, a little bigger than the fish, on a rimmed cast-iron skillet or foil-lined sheet pan. Lay the fish on the bed and pack the remaining salt over it in an even shell, leaving just the tip of the tail showing.
Roast for 25 minutes. Set the pan over the indirect zone, close the lid, and roast for 25 minutes, until the crust is set hard and faintly golden. To check doneness, push an instant-read thermometer through the crust at the thickest part behind the head — the fish should read 145°F.
Rest inside the crust. Let the fish rest in its crust for 10 minutes. It stays steaming hot inside its shell.
Crack the crust tableside. Carry the pan to the table, crack the crust open with the back of a knife or a spoon, and lift the shell away in pieces, brushing off any loose salt. Fillet the fish, drizzle with your best extra-virgin olive oil, and serve with lemon wedges.
Grilling tip: The crust is a cooking vessel, not a seasoning to eat — brush every crumb off the fillets before serving, and warn your guests that a stray grain of the shell is a salty surprise.
