Also question is, how do you keep grated Parmesan cheese fresh?
Sharp in flavor with a granular texture, this cheese is primarily used for grating. To keep Parmesan fresh, proper storage is necessary: It should be wrapped tightly in plastic wrap and kept in the refrigerator.
Subsequently, question is, do you have to refrigerate grated Parmesan cheese? Soft cheeses such as cream cheese, cottage cheese, shredded cheeses, and goat cheese must be refrigerated for safety. As a general rule, hard cheeses such as cheddar, processed cheeses (American), and both block and grated Parmesan do not require refrigeration for safety, but they will last longer if kept refrigerated.
In this manner, how long can you keep grated Parmesan cheese in the fridge?
How Long Does Parmesan Cheese Last
| Fridge | |
|---|---|
| Parmesan (unopened) | 7 – 9 months or Use-by + 1 month |
| Parmesan (opened) | 4 – 6 weeks |
| Shredded/grated parmesan (sold refrigerated, unopened) | Use-by + 7 days |
| Shredded/grated parmesan (sold refrigerated, opened) | 3 – 7 days |
Does grated Parmesan cheese go bad?
Grated Parmesan cheese that was sold unrefrigerated will generally stay at best quality for about 10 to 12 months in the refrigerator after it has been opened. Properly stored, grated Parmesan cheese will maintain best quality for about 18 months in the freezer, but will remain safe beyond that time.
