Whole Fish Baked in a Salt Crust
This is the most reliable way to cook a whole fish for a group. The salt crust acts as an insulator, ensuring the fish stays succulent regardless of slight variations in oven temperature.
The crust is not meant to be eaten.
It is a cooking vessel, not a seasoning to be consumed. Ensure your fish is completely dry before packing it, or the salt will draw out too much moisture.

What goes in.
- 3 lbwhole sea bass or snapper, cleaned and scaled
- 4 cupscoarse kosher salt
- 2large egg whites
- 1/4 cupwater
- 3lemon slices
- 4sprigs of fresh thyme
Binding the Crust
Mixing the salt with egg whites and just enough water turns it into a wet-sand consistency that packs firmly. This bond is vital; if it's too dry, the crust will crumble before the fish is cooked.
The method.
Prep the fish
Pat the fish dry with paper towels inside and out. Stuff the cavity with lemon slices and thyme sprigs.
Mix the salt
In a bowl, combine the salt, egg whites, and water. Stir until it feels like heavy, damp sand.
Build the base
Spread one-third of the salt mixture onto a parchment-lined baking sheet in the shape of your fish.
Pack the crust
Lay the fish on the salt base. Cover the fish completely with the remaining salt, pressing firmly so there are no gaps or exposed skin.
Bake
Place in an oven preheated to 425°F (220°C). Bake for 25 to 30 minutes. The crust should be firm and pale gold.
Crack and serve
Remove from the oven and let rest for 5 minutes. Use the back of a large spoon or a small hammer to crack the shell. Carefully lift away the salt pieces and peel back the skin to access the fillets.
Other turns to take.
Aromatic Salt
Mix crushed fennel seeds, dried bay leaves, or citrus zest into the salt mixture before adding the egg whites.
When it doesn't go to plan.
Leave the head and tail on; they provide structure and make the final presentation cleaner.
If you feel resistance when inserting a skewer through the thickest part of the fish, it needs two more minutes.
Use a stiff brush to clear away any loose salt grains from the fish skin after cracking the crust open.
The ones that keep coming up.
Will the fish taste too salty?
No. Because the skin remains intact during the baking process, it acts as a barrier that prevents the salt from penetrating the meat.
Can I use table salt?
Avoid it. Table salt is too fine and will dissolve too quickly or create a crust that is far too hard to break.
