Loup de Mer en Croûte de Sel Recipe

This Loup de Mer en Croûte de Sel recipe transforms a whole sea bass into an impressive French seafood centerpiece by baking it beneath a thick crust of coarse salt and egg whites. Featured on Dinner in Paris, host Romain Avril stuffs the fish with lemon, shallot, parsley, tarragon, thyme, and capers before serving the tender sea bass with a flavorful saffron rouille and crisp golden croûtons. The result is a sophisticated main course that combines delicate fish, aromatic herbs, creamy sauce, and crunchy bread in one memorable French-inspired meal.

The Inspiration

Loup de Mer en Croûte de Sel is a striking example of a cooking technique that looks dramatic at the table while serving a practical purpose in the kitchen. Baking a whole fish inside a salt crust creates a sealed cooking environment that helps hold in steam and moisture. The fish cooks gently inside the hardened shell, allowing its natural flavor and delicate texture to remain at the center of the dish.

In this preparation from Dinner in Paris, Romain Avril fills the cavity of the sea bass with lemon slices, shallot, parsley, tarragon, capers, and thyme. These ingredients perfume the fish from the inside as it cooks, creating a fresh and aromatic flavor profile without relying on a heavy sauce.

Together, these three elements create a beautifully balanced French seafood meal. The fish is moist and gently flavored, the rouille is creamy and aromatic, and the croûtons introduce a satisfying crisp texture.

Ingredients

For Loup de Mer

1 whole sea bass (1.2–1.5 kg / 2.5–3 lb), cleaned
2 kg / 4.5 lb coarse salt
6 egg whites
1 lemon, sliced
2 sprigs thyme
2 sprigs parsley
2 sprigs of tarragon
1 tbsp capers
1 shallot, sliced
1/4 cup olive oil
Lemon wedges, for serving
Black pepper, to taste

For Rouille

3 garlic cloves, grated on a rasp
2 slices of whites bread, crustless
1 egg yolk
1 tbsp Dijon mustard
1 tbsp tomato paste
3/4 cup cup olive oil
1 tbsp hot water
Pinch saffron
Juice of 1 lemon
1 tsp piment d’Espelette, ground
Salt, to taste

For Croûtons

4 slices of baguette 1/2 inch thick cut on a bias
2 tbsp olive oil
Salt and pepper, to taste

Method

Make Loup de Mer

Preheat oven to 200°C / 400°F. Stuff the fish with lemon slices, shallot, parsley, tarragon, capers and thyme.
Drizzle half the olive oil inside the cavity of the fish. Rub the other half of the olive oil on the skin of the fish.
Season fish with black pepper. In a large mixing bowl, mix together the salt and egg white until you have a nice thick paste.
On a baking sheet with parchment paper, spread a small amount of the salt mixture.
Place stuffed fish over top. Cover the fish completely with remaining salt mixture and pat down with your hands.
Place fish in the oven and bake for 35–40 minutes. Remove from oven and let it keep cooking with the residual heat for 10 minutes.
With the back of a large knife, crack the crust open and remove it to expose the fish.
Peel the skin off gently. With a fork, gently remove the flesh from the fish and transfer to a serving plate.
Try to avoid the small bones.

Make Rouille

Mix saffron with hot water and let sit for 5 minutes to infuse flavour and colour. Chop up bread into small pieces and place in the bowl of a food processor. Add the garlic, Dijon, egg yolk, tomato paste and piment D’Espelette. Pulse until a smooth paste in formed. Add saffron water and pulse again. While the food processor is turning, stream in oil slowly to emulsify like a mayonnaise. Once it is nice and thick. Season with lemon juice, salt and pepper. Transfer to a nice serving bowl.
Make croutons. Pre-heat oven to 375F. Brush baguette slices with oil. Place oiled bread on a baking sheet and toast in the oven for 6-7 minutes or until crunchy and golden brown. Remove from the oven and bring to room temperature.
Spread Rouille over the toasted baguette and serve alongside Loup de Mer en Croute de Sel. Enjoy!

Serving Suggestions

This elegant Loup de Mer en Croûte de Sel recipe is especially well suited to dinner parties and special occasions because the salt crust creates a dramatic presentation before the fish is served. Bringing the whole salt-covered sea bass to the table before cracking the crust can turn the main course into an engaging part of the dining experience.

For a complete French-inspired menu, the fish can follow a vegetable appetizer such as Poireaux Vinaigrette or a light tomato tart. A simple fruit-based dessert or delicate custard makes an excellent finish after the seafood main course.

The rouille can also be placed in a bowl at the center of the table, allowing guests to add more to their croûtons or enjoy a small amount with the fish itself. Its garlic, saffron, lemon, and piment d’Espelette flavors complement the mild sea bass without overwhelming it.

Final Thoughts

This Loup de Mer en Croûte de Sel recipe celebrates a classic French approach to whole fish by enclosing sea bass in a protective salt crust that preserves moisture and concentrates flavor. Lemon, shallot, parsley, tarragon, thyme, capers, olive oil, and black pepper perfume the fish while it cooks, creating a tender and aromatic result.
