Koulibiac

Koulibiac (coulibiac) is a grand Russian pie that wraps salmon, rice, nutmeg-seasoned spinach, and hard-boiled eggs in golden puff pastry. It looks impressive on the table, but the assembly is really just stacking layers.

The rice gets mixed with cream, beaten egg, and lemon juice before it goes in. That binding turns the rice from loose grains into a cohesive layer that slices cleanly instead of scattering across the plate when you cut into the pastry.

Layering order matters: rice on the bottom, then spinach, then salmon and the hard-boiled eggs, then spinach again, salmon again, and rice on top. This symmetrical stacking means every slice from edge to center has the same balance of filling.

Seal the edges firmly and cut a steam vent in the top. Trapped moisture is the enemy of crisp puff pastry.

Chef Tips

• Squeeze all excess water from the thawed spinach. Any leftover moisture will make the pastry soggy from the inside.
• Drain and mash the canned salmon well, removing any skin or bones. Fresh cooked salmon works even better if you have it.
• Let the koulibiac rest for 5 minutes after baking so the layers set and slices hold together.
• Equally good served cold the next day. The pastry softens but the filling flavors improve overnight.

Variations

• Mushroom duxelles: Add a layer of finely chopped sauteed mushrooms between the spinach and salmon for a more traditional French-influenced version.
• Smoked salmon: Use smoked salmon instead of canned for a richer, more luxurious filling.
