Shelf Stable Foods
How long do roasted nuts last after opening?
Once the tin is open, roasted nuts get 1–2 weeks in the pantry but 4 weeks in the fridge — moving them to the cold roughly doubles the window for nothing.
Pantry, opened
How long does it keep?
| Pantry, from purchase | Package use-by date |
|---|---|
| Pantry, opened | 1–2 weeks |
| Fridge, opened | 4 weeks |
Can it sit out?
Roasted nuts is shelf-stable, so sitting out at room temperature isn’t the safety question — storage time is.
How to tell if roasted nuts has gone bad
- A smell like crayons or old paint from inside the tin
- A bitter, soapy finish where there should be butter and toast
- Nuts that give softly instead of cracking
- Oil sweating out onto the surface of the kernels
When in doubt, throw it out.
Unopened, USDA hands the tin over to the package use-by date — it’s the opening, not the shelf, that starts the real countdown.
