Can I make beef and feta spanakopita rolls ahead of time?
Yes. Assemble the rolls, cover tightly with plastic wrap, and refrigerate up to 24 hours before baking. You can also freeze them unbaked for up to 3 months; bake from frozen, adding 5–10 minutes to the baking time.
How do I prevent phyllo dough from drying out while working with it?
Keep the stack of unused phyllo sheets covered with a damp towel. Work quickly with one sheet at a time, and brush each layer lightly with olive oil to seal in moisture.
What can I substitute for feta cheese in this recipe?
Use ricotta salata, goat cheese, or a mix of mozzarella and Parmesan. Feta is tangier, so adjust seasoning accordingly with less salt if needed.
Can I use frozen spinach instead of fresh?
Yes. Thaw frozen spinach completely and squeeze out excess moisture with a kitchen towel to prevent soggy rolls. Use about 3 oz frozen spinach (roughly equal to 5 oz fresh).
How do I know when the rolls are done baking?
The phyllo should be golden brown and crisp, typically after 20–25 minutes at 375°F. If the edges brown too quickly, tent loosely with foil and continue baking until the filling is heated through.
