phyllo dough sheets

Phyllo (also spelled filo) dough is a paper-thin pastry originating from Ottoman and Mediterranean cuisines, made from wheat flour, water, and a small amount of oil or butter. The dough is traditionally hand-stretched over a large work surface to achieve sheets thin enough to read text through, though commercial production now uses industrial rollers to attain the characteristic thickness of approximately 0.1mm. The result is a delicate, crisp pastry that becomes golden and flaky when baked, with a neutral flavor profile that serves as a vehicle for both sweet and savory fillings.

The primary characteristic of phyllo dough is its laminated structure, created through repetitive folding and brushing with fat between layers—similar in principle to puff pastry, though requiring no resting periods and using significantly less fat. Authentic phyllo contains no leavening agents; its flakiness derives entirely from the structural separation of thin layers. Commercial phyllo sheets are typically sold frozen in packages of 20-40 sheets and are fragile once thawed, requiring careful handling.

Phyllo dough is fundamental to Mediterranean, Middle Eastern, and Greek cuisines, where it serves as the foundation for both savory and sweet preparations. Savory applications include börek (filled pastries), spanakopita (spinach pie), and baklava's savory variants, while sweet uses encompass baklava (layered pastry with nuts and honey), galaktoboureko (custard pie), and apple strudel. The dough is typically layered multiple times, with brushing of melted butter or oil between each sheet to achieve maximum crispness and separation during baking. Phyllo's delicate nature makes it ideal for creating contrasting textures—the crisp exterior against creamy, spiced, or fruit-based fillings. It is occasionally used in modern cuisine for non-traditional applications such as crisped noodles or vegetable wraps.
