Salmon coulibiac brings a savory filling together inside golden puff pastry. Here, tender salmon sits with mushroom rice and hard-cooked eggs, while dill and lemon zest add fresh, bright notes.
The key to a tidy pastry crust is letting the rice and mushroom mixture cool before you assemble the coulibiac. That gives you time to prepare the other components without asking the cold pastry to hold a warm filling.
Build flavor into the rice
Long-grain white rice cooks in low-sodium chicken broth, giving the grains a savory base that complements the salmon. Once the rice is tender, let it stand covered as directed on the recipe card; that helps it finish absorbing the broth before you fluff it.
Cook the finely chopped cremini mushrooms and yellow onion until the mushrooms release their moisture and most of it evaporates. This matters for both flavor and texture: excess liquid can make the rice mixture wet. Add the minced garlic near the end so it cooks briefly, then fold the vegetables into the rice with dill, lemon zest, and salt. Black pepper seasons the mushroom mixture and salmon.
Cool the filling before wrapping
Spread the finished rice mixture over a plate or tray to cool. This is the most important pastry detail: warm filling can soften the puff pastry before it bakes, making the bottom harder to handle and the crust less crisp. Keep the thawed pastry cold while you prepare the salmon and eggs.
Pat the skinless center-cut salmon dry before seasoning it. Drying the surface helps the seasoning cling and avoids adding unnecessary moisture to the filling. The hard-cooked eggs are cut lengthwise and arranged alongside the salmon, where they become part of each slice.
Seal and bake for a golden crust
Use one pastry sheet as the base and keep the filling in a centered strip, leaving room around the edges to seal. Layer the rice, salmon, egg halves, and remaining rice as described on the recipe card. Cover with the second sheet, tuck its edges beneath the base, and press to seal so the filling stays enclosed.
Brush the top with egg wash for a deep golden finish, and cut small vents to let steam escape. Watch for both signs of doneness on the card: the pastry should be deep golden, and the thickest part of the salmon should reach the listed temperature. Let the coulibiac rest before slicing; a sharp serrated knife helps cut through the pastry without crushing its layers.
Frequently Asked Questions
Why does the rice filling need to cool before assembly?
Warm rice and mushrooms can soften the cold puff pastry before it goes into the oven. Spreading the filling on a plate or tray helps it cool, so the pastry is easier to seal and can bake into a flaky crust.
How can I keep the mushroom rice from becoming wet?
Cook the mushrooms and onion until the mushrooms have released their moisture and most of it has evaporated. Then combine them with the rice and cool the mixture before assembling, as directed on the recipe card.
How do I know when the coulibiac is done?
Look for pastry that is deep golden, then check the thickest part of the salmon against the temperature listed on the recipe card. After baking, let the coulibiac rest for the listed time before cutting with a serrated knife.

Ingredients
- Mushroom rice and eggs
1 cup long-grain white rice
1 3/4 cups low-sodium chicken broth
3 large eggs
2 tablespoons unsalted butter
8 ounces cremini mushrooms, finely chopped
1/2 cup finely chopped yellow onion
2 garlic cloves, minced
1 1/4 teaspoons kosher salt, divided
1/4 teaspoon black pepper, divided
2 tablespoons chopped fresh dill
1 teaspoon lemon zest
- Pastry and salmon
1 package (17.3 ounces) frozen puff pastry, thawed but cold (2 sheets)
1 1/2 pounds skinless center-cut salmon fillet
1 large egg, beaten with 1 tablespoon water, for egg wash
Directions
- Place the 3 eggs in a saucepan and cover with water. Bring to a boil, then gently boil for 10 minutes. Transfer the eggs to cold water, peel, and cut them in half lengthwise.
- Combine the rice and chicken broth in a saucepan and bring to a boil. Cover, reduce the heat to low, and simmer for 15 minutes, until the liquid is absorbed and the rice is tender. Remove from the heat and let stand, covered, for 5 minutes.
- While the rice stands, melt the butter in a large skillet over medium-high heat. Add the mushrooms and onion and cook for 7 minutes, stirring often, until the mushrooms have released their moisture and it has mostly evaporated. Add the garlic and cook for 1 minute. Season with 1/2 teaspoon of the salt and 1/8 teaspoon of the pepper.
- Fluff the rice and stir in the mushroom mixture, dill, lemon zest, and remaining 1/2 teaspoon salt. Spread the mixture on a plate or tray and cool for 20 minutes. Preheat the oven to 400°F and line a rimmed baking sheet with parchment paper.
- Pat the salmon dry and season it with the remaining 1/4 teaspoon salt and 1/8 teaspoon pepper. On the baking sheet, roll one pastry sheet into a rectangle about 10 by 14 inches. Spoon half the rice mixture down the center in a strip about 4 inches wide. Set the salmon on top, arrange the egg halves along its sides, and mound the remaining rice over the fish.
- Roll the second pastry sheet into a rectangle large enough to cover the filling. Lay it over the top, tuck the edges under the bottom sheet, and press to seal. Brush with the beaten egg, cut several small steam vents in the top, and bake for 35 minutes, until the pastry is deep golden and the thickest part of the salmon reaches 145°F.
- Let the coulibiac rest for 10 minutes before slicing with a sharp serrated knife.
Notes
- Cool the rice and mushroom filling before assembling; warm filling can soften the puff pastry before it bakes.
