Salt Baked Branzino (Whole Fish Baked in Salt Crust)
If you’ve never cooked fish in a salt crust before, this is your moment.
Salt baked branzino looks dramatic, tastes incredible, and is actually one of the easiest ways to cook whole fish. The salt crust seals in moisture, gently steams the fish, and creates the most tender, flaky texture.
And no — it does NOT taste overly salty.
This is one of those recipes that feels like something you’d order at a coastal restaurant… but you can absolutely make it at home.
Why Bake Fish in Salt?
Cooking fish in a salt crust:
- Locks in moisture
- Protects the delicate flesh
- Infuses gentle herb and citrus flavor
- Prevents overcooking
- Creates a show-stopping presentation
The egg whites bind the salt together into a “sandy” mixture that hardens in the oven, forming a shell around the fish.
Inside that shell? Perfectly steamed, buttery branzino.
What Is Branzino?
Branzino (also known as European sea bass) is:
- Mild and slightly sweet
- Tender but firm
- Low in fishy flavor
- Perfect for whole roasting
If you can’t find branzino, look for whole sea bass, red snapper, or dorade.
Ingredients
- 1 large branzino (cleaned and scaled)
- 1 bunch fresh thyme
- 1 bunch fresh dill
- 1 large lemon
- 3 egg whites
- 2½ cups kosher salt
- 2 tsp black pepper

- Serves: 2–4
How to Make Salt Baked Fish
Step 1: Preheat the Oven
Preheat your oven to 400°F.
Step 2: Prep the Fish
Rinse the fish and herbs.
Pat everything completely dry. Dry fish helps the salt adhere properly.
Season the inside and outside of the fish with black pepper.
Step 3: Make the Salt Mixture
Separate the egg whites from 3 eggs.
In a bowl, mix the egg whites with 2½ cups kosher salt.
The texture should feel like damp sand.
If it’s too wet, add more salt a little at a time.
Step 4: Stuff the Fish
Thinly slice the lemon.
Layer lemon slices, thyme, and dill inside the cavity of the fish.
Reserve 3 lemon slices to place on top of the fish before sealing.
Step 5: Create the Salt Crust
Spread a thin layer of salt mixture on a baking sheet.
Place the fish on top.
Cover the entire fish with the remaining salt mixture, pressing firmly to seal completely.
No gaps. The fish should be fully encased.
Step 6: Bake
Bake at 400°F for 20-25 minutes.
After 15 minutes, check the crust. It should feel hard when tapped and begin browning slightly at the edges.
If needed, cook up to 10 additional minutes.
How to Tell When It’s Done
The crust will:
- Be firm and hardened
- Sound hollow when tapped
- Slightly browned at edges
Internal temperature of fish should reach about 130–135°F for flaky perfection.
How to Serve
Let the fish rest 5 minutes.
Crack the salt crust gently with the back of a spoon.
Brush away excess salt.
Carefully lift off the skin and remove the fillets from the bones.
Drizzle with olive oil and fresh lemon juice before serving.
Does Salt Baked Fish Taste Salty?
No.
The salt crust acts as insulation, not seasoning.
Because the fish is not directly salted (other than a little pepper), the flesh absorbs gentle flavor without becoming overly salty.
It’s surprisingly balanced.
