Expiration & Storage Tips
When does phyllo dough expire?
Store-bought phyllo dough can last up to a month past its printed date when unopened and kept in the refrigerator. Once opened, it is best to use it within three days, otherwise the thin layers can become dry and difficult to separate. The good news is you can freeze unopened phyllo dough for up to 12 months, and even opened packages will last for a few weeks if properly stored in an airtight container. If you made homemade phyllo dough, it should be used immediately or frozen up to one month.
How do you tell if phyllo dough is bad?
Some of the tell-tale signs that phyllo dough has gone stale include a dull color, a brittle texture and a lack of moisture. It might also have a sour smell or visible mold growth, which is a clear signal to discard it right away. It might also have lost its elasticity making it difficult to unfold without tearing.
Tips for storing phyllo dough to extend shelf life
• Keep your phyllo dough in the refrigerator until you are ready to use it. This helps maintain its texture and prevents it from drying out.
• If you're using frozen phyllo dough, always thaw it overnight in the refrigerator. Avoid using a microwave to defrost it as this can make it soggy.
• If you only use part of the package of phyllo, roll the unused portion tightly, wrap it in plastic, and refrigerate it. This will prevent it from drying out for the next time you want to use it.
• Phyllo dough can be sensitive to air. If you have to stop halfway through a recipe, cover the open package with a slightly damp towel to keep it from drying out.
• If you need to freeze phyllo dough, wrap it tightly in plastic wrap and then a layer of foil. This helps prevent freezer burn and extends its shelf life.
