Can I make spanakopita ahead of time?
Yes. Assemble the triangles, freeze them on a baking sheet, then transfer to a bag for up to 3 months. Bake directly from frozen, adding 5–10 minutes to bake time.
How do I keep phyllo dough from drying out?
Cover unused phyllo sheets with a damp kitchen towel while working. Phyllo dries quickly once exposed to air.
Can I use thawed frozen spinach instead of fresh?
Yes, but squeeze it very dry first to avoid a watery filling. Use about 2 cups thawed spinach to replace the fresh.
What can I substitute for Greek feta?
Bulgarian feta or ricotta mixed with a sharp cheese (like Pecorino) works in a pinch, though flavor will differ.
How do I know when spanakopita is done baking?
The phyllo should be deep golden brown and crisp, and the filling should feel warm to the touch when you pierce a triangle.
