Parmesan in Fridge: How Long is Too Long? Find Out!
This guide will help you understand how to properly store Parmesan cheese and determine how long it stays fresh in your refrigerator, answering the key question: "how long does parmesan cheese last in the fridge?".
Understanding Parmesan Cheese: Factors Affecting Shelf Life
Parmesan cheese, known for its hard texture and savory flavor, can last a relatively long time compared to softer cheeses. However, several factors influence its shelf life:
- Type of Parmesan: Whole blocks, wedges, grated, and shredded Parmesan have different shelf lives due to varying surface areas exposed to air and moisture.
- Storage Method: Proper storage significantly impacts longevity. Airtight containers and proper temperature control are crucial.
- Original Packaging: The quality of the original packaging affects how well the cheese is protected from environmental factors.
- Handling: Cross-contamination from unclean utensils can introduce bacteria, shortening its lifespan.
"How Long Does Parmesan Cheese Last in the Fridge?" - A Detailed Breakdown
The answer to "how long does parmesan cheese last in the fridge?" depends on the form of Parmesan. Here's a breakdown:
Whole Block of Parmesan
- Unopened: Can last for 2-4 months beyond the "sell-by" date printed on the packaging when refrigerated at a consistent temperature.
- Opened: Once opened, a whole block of Parmesan can last for 2-3 months in the refrigerator if stored properly.
Wedge of Parmesan
- Unopened: Similar to a whole block, an unopened wedge can last 2-4 months beyond its "sell-by" date.
- Opened: An opened wedge lasts approximately 1-2 months in the refrigerator, given proper storage.
Grated Parmesan (Pre-Grated in a Container)
- Unopened: Can last 1-2 weeks beyond the "sell-by" date when refrigerated.
- Opened: Once opened, use within 7-10 days.
Shredded Parmesan (Pre-Shredded in a Bag)
- Unopened: Similar to grated, usually lasts 1-2 weeks beyond the date on the packaging.
- Opened: Consume within 5-7 days after opening to maintain optimal freshness and flavor.
Best Practices for Storing Parmesan Cheese in the Fridge
Here are some practical tips to maximize the shelf life of your Parmesan:
- Airtight Container: After opening, always transfer Parmesan to an airtight container or wrap it tightly in plastic wrap, followed by foil. This minimizes exposure to air and moisture, preventing mold growth.
- Temperature Control: Store Parmesan in the coldest part of your refrigerator, typically the bottom shelf or a cheese drawer. Avoid storing it in the door, where temperatures fluctuate more.
- Minimize Handling: Use clean utensils when handling the cheese to prevent contamination.
- Avoid Freezing (Ideally): While you can freeze Parmesan, it can alter the texture, making it more crumbly. If you must freeze, shred or grate it first and store it in a freezer-safe bag. Use within 2-3 months.
Identifying Spoiled Parmesan
Even with proper storage, Parmesan can eventually go bad. Look for these signs:
- Mold Growth: This is the most obvious sign. While you might be able to cut off a small amount of mold on a hard block, it's generally best to discard the cheese if mold is present.
- Ammonia Smell: A strong ammonia smell indicates that the cheese has begun to break down.
- Hard and Dry Texture: While Parmesan is naturally hard, excessive hardness and dryness can indicate that it's past its prime.
- Slimy Texture: This is a sign of bacterial growth and indicates spoilage.
- Off-Flavor: If the cheese tastes sour or has an unusual flavor, it's likely spoiled.

Parmesan Cheese in the Fridge: FAQs
Here are some frequently asked questions about storing Parmesan cheese in your refrigerator to help you keep it fresh and delicious for as long as possible.
What's the best way to store Parmesan cheese in the fridge?
The best way to store Parmesan cheese in the fridge is wrapped tightly in plastic wrap or beeswax wrap, or in an airtight container. This prevents it from drying out and absorbing odors from other foods. Proper storage is crucial to preserving quality.
How long does Parmesan cheese last in the fridge after opening?
Generally, a block of Parmesan cheese will last for about 2-3 months in the fridge after opening, if stored properly. Grated or shredded Parmesan has a shorter lifespan, typically 2-3 weeks, because more surface area is exposed to air and moisture. So how long does parmesan cheese last in the fridge really depends on form and storage.
Can I freeze Parmesan cheese to extend its shelf life?
Yes, you can freeze Parmesan cheese. Hard cheeses like Parmesan freeze well. Wrap it tightly or place it in a freezer-safe bag. It may become a little crumbly after thawing, but it will still be fine for cooking. Frozen parmesan can last up to 12-18 months.
How can I tell if my Parmesan cheese has gone bad?
Look for signs of mold, a slimy texture, or an ammonia-like smell. These indicate spoilage, and the cheese should be discarded. While a bit of surface mold can be cut away from hard cheeses, it's best to err on the side of caution.
