Step-By-Step Guide to Making Salt-Crusted Fish

Salt-Crusted Fish


Salt-crusted fish is a culinary masterpiece that has been delighting palates for generations. This cooking technique, often referred to as “en croûte” in French cuisine, involves encasing a whole fish in a thick layer of salt, which not only seasons the fish but also locks in moisture, resulting in tender and flavorful seafood. While the process may sound intimidating, making salt-crusted fish at home is surprisingly straightforward. In this step-by-step guide, we will take you through the process of creating this delectable dish in the comfort of your own kitchen.


Before diving into the detailed steps, let’s gather the essential ingredients:

3. Fresh herbs (rosemary, thyme, or parsley)
4. Zest of a lemon or orange
5. Egg whites (3-4 large eggs)
6. Water
7. Olive oil
8. Lemon wedges for garnish

Now that we have everything ready, let’s dive into the step-by-step guide:

Step 1: Preparing the Salt Mixture

Start by preheating your oven to 400°F (200°C) and positioning the rack in the center. In a mixing bowl, combine the kosher salt and egg whites. Whisk the mixture until it has a wet sand-like consistency. This salt dough will serve as the protective crust for your fish.

Step 2: Adding Flavor

Enhance the flavor of your salt mixture by adding fresh herbs (rosemary, thyme, or parsley), citrus zest (lemon or orange), and a generous amount of freshly ground black pepper. Mix these ingredients into the salt dough, ensuring an even distribution of flavors.

Step 3: Stuffing the Fish

Before encasing the fish in salt, season the inside of the fish with salt and pepper. You can also add extra flavor by stuffing the cavity with lemon slices, fresh herbs, and a drizzle of olive oil. This infuses the fish with incredible aroma and taste.

Step 4: Coating the Fish

Lay a piece of parchment paper on your baking tray or roasting pan. Place a thin layer of the salt mixture on the parchment paper to create a base for the fish. This ensures the fish won’t stick to the pan.

Step 5: Encasing the Fish

Lay your seasoned fish on the salt base, and begin covering it completely with the salt mixture. Make sure the entire fish is enclosed, leaving no gaps. The salt should form a thick, protective crust around the fish.

Step 6: Baking the Fish

Place the fish in the preheated oven and let it bake for about 25-30 minutes per pound. You can check the doneness of the fish by inserting a kitchen thermometer through the salt crust into the thickest part of the fish. The internal temperature should reach 135°F (57°C).

Step 7: Resting

Once the fish is done, carefully remove it from the oven. Allow it to rest for 10-15 minutes. Resting helps the fish continue cooking and ensures it remains moist and flavorful.

Step 8: Cracking the Crust

After the resting period, it’s time to unveil your masterpiece. Use a knife or the back of a spoon to gently crack the salt crust. Be cautious not to let any salt fall onto the fish. Remove the crust, and you’ll be left with a perfectly cooked, tender fish.

Step 10: Enjoying the Flavors

Enjoy your salt-crusted fish with a side of roasted vegetables, a fresh salad, or crusty bread. The fish is perfectly seasoned and infused with the herbs and citrus flavors, making each bite a culinary delight.
