Parmesan cheese is a popular and versatile cheese that is loved by many. It is known for its rich and nutty flavor, and it adds a delightful touch to various dishes, such as pasta, salads, and soups. But what happens when you buy a big block of Parmesan cheese and can’t finish it all at once? How long does Parmesan cheese last in the refrigerator? In this article, we will explore the storage and shelf life of Parmesan cheese and provide you with a comprehensive guide on how to keep it fresh for as long as possible.
How to Store Parmesan Cheese
Proper storage is crucial to maintaining the freshness and quality of Parmesan cheese. When you bring home a piece of Parmesan cheese, it is essential to store it correctly to prevent it from going bad too quickly.
1. Original Packaging
When you buy Parmesan cheese, it usually comes in a vacuum-sealed package or a plastic wrap. It is best to keep the cheese in its original packaging until you are ready to use it. The packaging is specifically designed to preserve the cheese’s flavor and texture, helping it last longer in the refrigerator.
2. Airtight Container
If you have already opened the original packaging or prefer to store Parmesan cheese in a different container, make sure to choose an airtight one. Air can cause the cheese to dry out and become hard, so it is essential to protect it from exposure. Consider using a resealable plastic bag or airtight container, ensuring it is properly sealed to keep moisture and air out.
3. Cold Storage
Parmesan cheese should always be stored in the refrigerator, as the cold temperature helps extend its shelf life. Find a spot in your fridge where the temperature is the most stable, such as the cheese drawer or the lower shelves. Avoid storing it in the door as the temperature fluctuates there due to the frequent opening and closing of the refrigerator.
4. Away from Odor-Producing Foods
Parmesan cheese has a strong aroma and can easily absorb other odors present in the refrigerator. To prevent your cheese from tasting like other foods, store it away from strong-smelling items such as onions, garlic, and certain fruits.
Shelf Life of Parmesan Cheese
Parmesan cheese, when stored properly, has an impressive shelf life. However, it is important to understand that the shelf life may vary depending on whether the cheese is grated or in block form.
1. Whole Block Parmesan Cheese
If you have a whole block of Parmesan cheese, it can last for several months in the refrigerator. When stored correctly, unopened Parmesan cheese can stay fresh for up to 6 months. This is because the vacuum-sealed packaging or plastic wrap acts as a barrier, protecting the cheese from moisture and air.
2. Grated Parmesan Cheese
Grated Parmesan cheese, on the other hand, has a shorter shelf life compared to the whole block. Once the packaging has been opened, it is recommended to consume the grated cheese within 3 to 4 weeks. It is highly vulnerable to moisture and contamination, so it is crucial to handle it with care and store it properly.
Signs of Spoiled Parmesan Cheese
While Parmesan cheese has a long shelf life, it is important to know the signs of spoilage to ensure that you are consuming it at its best quality. Here are some indicators that your Parmesan cheese has gone bad:
1. Mold Growth
If you notice mold on the surface of the Parmesan cheese, it is a clear sign that it has spoiled. Mold can appear as white or green spots, and it is crucial to discard the cheese immediately if you see any signs of mold growth.
2. Bad Odor
Fresh Parmesan cheese has a pleasant and nutty aroma. If you detect a strong, unpleasant odor coming from the cheese, it is likely that it has spoiled. Trust your sense of smell and discard the cheese if it smells off.
3. Change in Texture
Parmesan cheese should have a hard and crumbly texture. If it becomes excessively soft, oily, or develops a slimy coating, it is a sign that it has gone bad. The texture change may indicate bacterial growth, and it is best to err on the side of caution and discard it.
Frequently Asked Questions
1. Can you freeze Parmesan cheese?
Yes, you can freeze Parmesan cheese! Freezing is an excellent option to extend the shelf life of Parmesan cheese even further. Simply wrap the cheese tightly in plastic wrap or place it in a freezer bag, ensuring it is properly sealed to prevent freezer burn. Frozen Parmesan cheese can last for up to 8 months without losing its flavor and quality.
2. Can you eat Parmesan cheese after the expiration date?
The expiration date on Parmesan cheese is a guideline provided by the manufacturer. While the cheese may still be safe to consume after the expiration date, it may not be at its best quality. It is always recommended to use your judgment and rely on your senses to determine if the cheese is still good to eat.
3. Can you trim molds off Parmesan cheese?
It is generally not advisable to trim molds off Parmesan cheese. Mold can penetrate deep into the cheese, making it difficult to remove entirely. Additionally, the presence of mold may indicate the presence of other harmful bacteria. To ensure your safety, it is best to discard the entire piece of cheese if you spot any mold.
