filo dough

Phyllo dough (also spelled filo or fille) is an extremely thin, delicate pastry sheet made from a simple dough of wheat flour, water, salt, and often a small amount of oil or vinegar. Originating in Ottoman cuisine and becoming fundamental to Greek, Turkish, Middle Eastern, and Balkan cooking traditions, phyllo is distinguished by its paper-thin sheets—typically rolled or stretched to nearly transparent thickness. The dough requires no leavening agent; its characteristic crispy, flaky texture develops from the lamination created by brushing oil or melted butter between individual sheets before baking. Commercial phyllo is typically sold frozen in packages containing dozens of pre-rolled sheets, though fresh phyllo is also available in regions with strong Eastern Mediterranean culinary traditions.

The dough itself is relatively neutral in flavor, allowing it to serve as a versatile vessel for both sweet and savory fillings. When baked, the multiple oiled layers crisp and shatter delicately, creating a distinctive textural contrast with dense fillings.

Phyllo dough serves as the foundation for numerous pastries across Mediterranean and Middle Eastern cuisines. Savory applications include spanakopita (spinach pie), tyropita (cheese pie), börek (Turkish filled pastries), and samosas in South Asian adaptations. Sweet preparations feature baklava (layered pastry with nuts and honey), galaktoboureko (custard pie), and various phyllo-wrapped fruits or cream fillings. The dough is brushed with melted butter or oil between each layer, then baked until golden and crispy. Working with phyllo requires gentle handling—sheets tear easily—and protection from drying by covering unused sheets with a damp towel. It is equally suited to individual hand-formed pastries or large assembled pies cut into portions after baking.
