How long does frozen puff pastry last?
Puff pastry keeps 12 months in the freezer, the only window USDA carries for it — once a sheet has thawed in the fridge, bake it rather than sending it back.

Can it sit out?
Puff pastry is perishable — the FSIS 2-hour rule applies.
Perishable food left at room temperature for more than 2 hours should be thrown out — 1 hour if it’s 90°F or hotter (a picnic, a hot car, a summer kitchen).
How to tell if puff pastry has gone bad
- Thick frost or ice crystals built up over the sheet
- Dough gone gray-brown and dried at the edges — freezer burn
- A stale, absorbed freezer smell in the raw dough
- Sheets that thawed at some point and fused into a solid block
When in doubt, throw it out.
Thaw it overnight in the fridge, never on the counter — warm butter melts into the flour and the layers never separate in the oven.
