How Long Is Grated Parmesan Cheese Good For After Opened
Parmesan cheese is good for about 3 months once it is opened. Cheese loses its flavor after this time. You should always store it in an airtight container away from heat and sunlight if you want to preserve the freshness of your cheese. Unopened, the Parmesan should last about 7 to 9 months.
When stored in a refrigerator, unopened grated Parmesan can be used up to several weeks past its stated expiration. The parmesan cheese should last for around 6 weeks after opening, provided that you keep your cheese refrigerated.
The amount of time a Parmesan will last after being opened will vary depending on the type of Parmesan (boiled, wedge, grated, or shredded) and the conditions under which the cheese was stored. Unfortunately, grated parmesan cheese does not last nearly as long as a wedge or block, so you may want to consume your cheese within 5-7 days to get the best flavors.

How long is grated Parmesan cheese good for after opening?
Due to air exposure and possible moisture, grated Parmesan cheese, like many dairy products, has a short shelf life after opening. The following are general recommendations for the storage life of grated Parmesan cheese after opening:
- Refrigerated Parmesan Cheese: Grated Parmesan cheese keeps well in the fridge for one to two months after opening it. It must be kept from direct sunlight and in an airtight container or resealable bag to prevent spoiling or mold growth.
- Vacuum-Sealed Parmesan Cheese: Grated Parmesan cheese that has been vacuum-sealed has a longer shelf life; it can typically be used for several months after opening. Storing it in the refrigerator and firmly resealing it after each use is still imperative.
- Freezing Parmesan Cheese: You can freeze grated cheese to increase its shelf life further. The cheese should be in an airtight receptacle or freezer-safe bag in the freezer. You can use frozen grated Parmesan cheese for six or eight months. When ready to use it, just don’t forget to thaw it in the refrigerator.
Always evaluate the quality of grated Parmesan cheese using your senses, including look and smell. Ignore it if it smells bad, grows mold, or has an odd texture. Proper storage techniques, such as tightly sealing and storing it in the freezer or refrigerator, can also help extend its freshness.
How can you tell if shredded Parmesan is still good?
You can determine if shredded Parmesan cheese is still good by using your senses and looking for signs of spoilage. Here are some things to consider:
- Smell: Give the cheese a sniff. Fresh Parmesan cheese should have a pleasant, nutty, and slightly tangy aroma. If it smells sour, rotten, or off-putting, it’s likely gone bad.
- Appearance: Examine the shredded Parmesan cheese for any visible signs of mold or discoloration. Mold growth can occur in cheese when it’s past its prime, and you should discard it if you see any moldy spots.
- Texture: Feel the texture of the cheese. Fresh Parmesan cheese should have a dry and crumbly texture. It may have spoiled if it feels slimy, sticky, or has an unusual texture.
- Taste: If you’re unsure after checking the smell and appearance, you can do a small taste test. Fresh Parmesan cheese should have a savory and slightly salty taste. If it tastes bitter, sour, or off, it’s best not to consume it.
- Expiration Date: Check the packaging’s expiration or “best by” date. While this date is a good guideline for freshness, it’s not always exact. Trust your senses over the date if the cheese appears and smells fine.
Remember that shredded Parmesan cheese, like other dairy products, can deteriorate over time, especially when exposed to air and moisture. Proper storage in an airtight container in the refrigerator can help extend its shelf life.
If you’re ever in doubt about the quality or safety of shredded Parmesan cheese, it’s best to err on the side of caution and discard it to avoid any potential health risks.

How do you store freshly grated Parmesan cheese?
Storing freshly grated Parmesan cheese properly is crucial to maintain its freshness and prevent it from spoiling. Here are some steps to store freshly grated Parmesan cheese effectively:
- Use an Airtight Container: Transfer the freshly grated Parmesan cheese to an airtight container. A resealable plastic or glass container with a tight-fitting lid is ideal. Ensure minimal air is inside the container to prevent moisture from getting in.
- Remove Excess Air: If using a plastic bag, squeeze out as much air as possible before sealing it. A vacuum-sealed bag or a container with a vacuum-sealing feature can also help remove excess air.
- Wrap in Plastic Wrap: If you don’t have an airtight container, you can wrap the cheese tightly in plastic wrap. Ensure there are no gaps or openings where air can enter.
- Store in the Refrigerator: Place the airtight container or wrapped cheese in the refrigerator. The cooler temperature helps slow down the growth of bacteria and preserves the cheese’s freshness.
- Avoid the Freezer: While you can freeze Parmesan cheese to extend its shelf life, freshly grated Parmesan may not freeze and thaw well, as it can become crumbly and lose some of its texture and flavor. It’s generally better to use it within a reasonable time frame when stored in the refrigerator.
- Keep Away from Moisture: Moisture is the enemy of Parmesan cheese. Ensure the container or wrapping is moisture-resistant and that the cheese is not exposed to condensation inside the refrigerator.
- Label and Date: If you store grated Parmesan cheese in a container, consider labeling it with the date of grating to help you keep track of its freshness.
- Use It Promptly: Freshly grated Parmesan cheese is best when used soon after grating. Try to use it within 1 to 2 weeks for the best flavor and texture.
Remember that Parmesan cheese, like other dairy products, can deteriorate over time and absorb odors from the refrigerator, so it’s essential to store it properly to maintain its quality. If you notice any signs of spoilage, such as an off smell, mold, or unusual texture, it’s best to discard the cheese.
