Deli cheese can be a convenient and tasty addition to sandwiches, salads, and more. But how long does it last in the fridge? The answer depends on several factors, including the type of cheese, the storage method, and the temperature of your refrigerator. Soft cheeses, such as ricotta, feta, and mozzarella, typically last about a week in the fridge, while semi-hard cheeses like cheddar and Gruyère can last two to three weeks. Hard cheeses, such as aged cheddar and Parmigiano Reggiano, have a much longer shelf life, remaining edible for about four weeks in the refrigerator. It's important to note that these are general guidelines, and the quality and taste of the cheese may decline before the end of these periods. Additionally, proper storage is crucial to maximizing the shelf life of deli cheese. This includes keeping the cheese at a constant temperature between 35-40°F, using airtight containers, and wrapping the cheese securely to prevent air exposure.

What You'll Learn
Deli cheese should be refrigerated at all times
Deli cheese is a versatile ingredient that can be used in a variety of dishes, from grilled cheese sandwiches to casseroles. To ensure food safety and maintain the quality of your deli cheese, it is important to follow proper storage practices, including refrigeration.
When storing deli cheese in the refrigerator, it is recommended to keep it in its original store packaging. This packaging is designed to maintain freshness and prevent contamination. If the original packaging is not available, wrap the cheese securely in wax paper, cheese paper, or parchment paper. Avoid using tight, non-porous materials like plastic wrap, as they can dry out the cheese and alter its texture.
In addition to refrigeration, proper handling practices are crucial. Always use clean utensils when handling deli cheese to prevent bacterial growth. If you are using pre-sliced cheese, consume it within two to three weeks of opening to maintain optimal taste and quality. For long-term storage, deli cheese can be frozen, ensuring it is wrapped tightly to prevent freezer burn and the absorption of other odours.
By following these guidelines and storing your deli cheese at the appropriate temperature in the refrigerator, you can maximize its shelf life, preserve its flavour and texture, and ensure safe consumption.

The shelf life of deli cheese depends on its moisture content
Semi-hard cheeses, such as cheddar, Gruyère, and Monterey Jack, have less moisture than soft cheeses. This means they have a slightly longer shelf life of two to three weeks in the fridge.
Hard cheeses, such as aged cheddar, aged Gouda, and Parmigiano Reggiano, have low moisture levels, making it difficult for bacteria to flourish. Therefore, hard cheeses can last about four weeks in the refrigerator once opened and about six months unopened.
The shelf life of cheese is also influenced by factors such as the form it is sold in, whether it is processed or "real" cheese, and the temperature at which it is stored. Proper storage is key to preserving the quality and safety of cheese.

Soft deli cheeses will last one week in the fridge
To ensure the quality and safety of soft deli cheeses, it is important to store them at a constant temperature of between 35-40°F (1.7-4.4°C). For optimum freshness, once opened, consumers should store the cheese in an airtight container or securely wrap it with plastic wrap or aluminium foil. It is beneficial to label the cheese with the opening date to track its freshness period accurately.
It is also possible to freeze soft deli cheeses for long-term storage. Before freezing, wrap individual slices or blocks of cheese with wax paper or cheese paper, followed by a layer of foil, or place them inside freezer bags. This process helps to prevent freezer burn and the cheese from absorbing other odours.
To summarise, soft deli cheeses will last one week in the fridge, but proper storage is essential to prolonging their shelf life.

Hard deli cheeses will last about four weeks in the refrigerator
Hard cheeses are low in moisture, which makes it difficult for bacteria to flourish. This means that, once opened, a package of hard cheese can last a long time—approximately four weeks in the refrigerator. This is in contrast to soft cheeses, which tend to spoil more quickly due to their higher moisture content.
Hard cheeses, such as aged cheddar, aged gouda, and Parmigiano Reggiano, will last about four weeks in the refrigerator. This is because hard cheeses have lower moisture levels, which means they lack the ideal environment for bacteria to thrive. In addition, unopened packages of hard cheese will last about six months in the refrigerator, according to the USDA.
To store hard cheese in the refrigerator, follow these steps:
- Remove the cheese from its plastic packaging.
- Wrap it loosely in cheese paper or wax paper.
- Put the cheese in a container with an airtight lid.
It's important to note that the shelf life of hard cheese can vary depending on the quality of the cheese, how it's stored, and other factors. Additionally, while hard cheese can be stored outside of the refrigerator, it will last much longer if it is refrigerated.
To determine if hard cheese is still safe to eat, look for signs of spoilage such as visible mold or an unpleasant odor. If you see mold on hard cheese, simply cut off at least 1 inch (2.5 cm) around and below the moldy spots.

Deli cheese can be frozen to extend its shelf life
When freezing deli cheese, it's important to use materials and containers that are specifically designed for freezer use, such as freezer-safe bags, containers, and paper. This will help prolong the lifespan and preserve the quality of the cheese. If you're freezing a block of cheese, cut it into portion sizes that you will use at one time, as you don't want to continuously thaw and refreeze a large block. Wrap the cheese in cheese paper or aluminum foil, seal it in an airtight freezer container or bag, and freeze it as quickly as possible.
If you're freezing sliced deli cheese, place a piece of parchment paper between each slice to prevent them from sticking together. Then, wrap the cheese in freezer paper and place it in an airtight freezer container or bag. For shredded deli cheese, simply place it in an airtight freezer bag. It's best to shred the cheese before freezing, as it will be softer and easier to shred.
Frozen deli cheese can last up to 9 months in the freezer, depending on the hardness and moisture content of the cheese. However, the quality may deteriorate if frozen for longer than 9 months. Once thawed, it's best to use the cheese within a couple of days to maintain its optimal taste and texture. To thaw frozen deli cheese, place it in the refrigerator for 7 to 9 hours or overnight.
