Bougatsa is a traditional, rustic Greek pie consisting of a phyllo pastry layered with a filling of semolina custard, although there are variations with minced meat or cheese. The name of the dish is a derivation of the Ottoman word pogatsa, denoting a pie filled with cheese.
Bougatsa has origins from the Byzantine period, when Constantinople was Greek, and it began as a dough that was stuffed with numerous sweet and savory fillings. Over time, bougatsa evolved to incorporate a thinly rolled, hand-made phyllo pastry. As many Turkish immigrants settled in Northen Greece, bougatsa became a specialty of Serres and Thessaloniki.
