Coulibiac is a Russian pie characterized by its oblong shape and various fillings such as salmon and buckwheat, cabbage with mushrooms and onions, or ground meat with rice and eggs. The pie is usually made with yeast dough, and the quantity of fillings should always exceed the quantity of pastry.

Coulibiac was invented in the 17th century in Russia, and it became popular in France in the 19th century, when French chefs brought it back home from Russia. It is recommended to pair the pie with a glass of milk or a cup of tea.
