How long does melted cheese last in the fridge? This is a question many cheese enthusiasts have likely wondered about at some point. The answer depends on the type of cheese and its moisture content. Generally, soft cheeses like Brie, Camembert, and fresh mozzarella should be consumed within a week of opening, whereas hard cheeses like Cheddar, Gouda, and Parmesan can last three to four weeks when stored properly. Proper storage techniques, such as wrapping cheese in porous materials like wax paper, can also extend the shelf life of melted cheese.

What You'll Learn
Soft cheeses last 1-2 weeks in the fridge
Soft cheeses, such as Brie, Camembert, and fresh mozzarella, can be stored in the fridge for 1-2 weeks after opening. However, it is recommended that they are consumed within one week of opening. This is because soft cheeses have a higher moisture content, making them more perishable and prone to bacterial growth. To maximise the shelf life of soft cheeses, they should be stored in the fridge at a temperature below 40°F (4°C).
To keep soft cheeses fresh, they should be wrapped tightly in wax paper, parchment paper, or cheese paper, and then placed in an airtight container or plastic bag. This helps to prevent the cheese from drying out while still allowing it to breathe. It is also important to avoid wrapping soft cheeses in tight, non-porous materials like plastic wrap, as this can cause them to dry out and harden.
When storing soft cheeses, it is crucial to inspect them regularly for any signs of spoilage. If there are spots of mould, cut off at least 1 inch (2.5 cm) around and below the affected areas, and the rest of the cheese should still be safe to consume. Additionally, if the cheese smells off, it is best to discard it.
It is worth noting that different types of soft cheeses may have varying shelf lives within the 1-2 week range. For example, fresh mozzarella is more delicate and perishable than other soft cheeses, so it is best to buy it close to when you plan on eating it. On the other hand, some soft cheeses like cottage cheese and cream cheese do not freeze well, so they should be consumed within the recommended timeframe without relying on freezing as a preservation method.

Hard cheeses last 3-4 weeks
Hard cheeses, such as cheddar, Parmesan, or Gouda, typically last 3-4 weeks in the fridge after opening. Unopened hard cheeses can be stored for about six months and do not require refrigeration. However, they will last much longer if they are refrigerated.
Hard cheeses have a lower moisture content than soft cheeses, which makes them less prone to bacterial growth and spoilage. This is why they have a longer shelf life than soft cheeses, which tend to spoil within 1-2 weeks.
To maximize the shelf life of hard cheeses, proper storage is essential. After opening, remove the cheese from its plastic packaging. Wrap it loosely in a breathable material, such as wax paper, parchment paper, or cheese paper. Then, place the wrapped cheese in an airtight container. Store it in the coldest and darkest part of the fridge, maintaining a temperature below 40°F (4°C).
When inspecting hard cheeses for spoilage, look for signs such as an unpleasant smell, a slimy surface, dark spots, dryness, cracks, or mold. If you notice mold, you can cut off at least 1 inch (2.5 cm) around and below the affected area. However, if there are extensive signs of spoilage, it is best to discard the cheese.

Soft cheeses with mould should be discarded
Soft cheeses, such as mozzarella, ricotta, and queso fresco, are meant to be consumed shortly after they are made and should be discarded if mould is found on them. This is because soft cheeses have a higher moisture content, which provides an ideal environment for bacteria to thrive and spoil the cheese.
While it is generally safe to cut off mould from hard cheeses, soft cheeses with mould should be thrown away. This is because soft cheeses tend to spoil more quickly than hard cheeses, and mould growth indicates that spoilage has occurred.
Mouldy cheese is not toxic, and it is unlikely that consuming a small amount will cause illness. However, it will taste unpleasant, and therefore, it is not advisable to consume mouldy soft cheese.
To prevent soft cheese from moulding, proper storage is essential. Soft cheese should be wrapped in wax, parchment, or cheese paper to maintain its moisture. It should be stored in an airtight container in the refrigerator at a temperature below 40°F (4°C).
Additionally, soft cheeses sold in brine, like feta or fresh mozzarella, should be kept in their liquid with a secure lid. Proper storage can help extend the shelf life of soft cheeses, which is typically about one week in the refrigerator.

Hard cheeses can be cut underneath the mould and eaten
The shelf life of cheese depends on its moisture content. Hard cheeses have less moisture than soft cheeses, which means they are less prone to spoilage from bacteria. Therefore, hard cheeses last 3-4 times longer than soft cheeses in the fridge. Most hard cheeses can be stored in the fridge for 3-4 weeks after opening, while soft cheeses can be stored for about a week. Unopened hard cheeses can be stored for about six months.
It is important to note that while it is unlikely that one will get sick from eating mouldy cheese, it is still best to avoid it. Mouldy cheese will taste bad, and some moulds can cause allergic reactions, respiratory problems, or, in rare cases, produce toxins that can make one sick. Therefore, it is recommended to cut off at least 1 inch (2.5 cm) around and below any mould spots on hard cheeses.
To prevent cheese from getting mouldy, it is important to store it properly. Cheese should be wrapped in special cheese paper, parchment paper, or wax paper and stored in the crisper drawer of the fridge, which has a consistent temperature and humidity. Alternatively, a dedicated wine fridge can be used to store cheese, as the temperatures are less cold, which is better for the cheese.

Store cheese at a temperature below 40°F (4°C)
To maximise the shelf life of melted cheese, it is crucial to adhere to proper storage procedures, specifically maintaining a temperature of under 40°F (4°C). This temperature range is vital for slowing bacterial growth and preventing spoilage.
Refrigerating melted cheese within this temperature range is essential for food safety. Higher temperatures significantly increase the rate at which bacteria multiply, elevating the risk of spoilage and foodborne illnesses. Therefore, it is advisable to invest in a fridge thermometer to ensure your refrigerator consistently operates at a safe temperature. Place the thermometer near the door, as it tends to be the warmest area of the fridge.
When storing melted cheese, wrap it in porous materials such as wax or parchment paper. This storage method helps maintain moisture and prevents the cheese from drying out. Avoid using tight, non-porous materials like plastic wrap, as they can accelerate drying and hardening.
Additionally, ensure that the cheese is placed on the top or middle shelf of the refrigerator, or in a drawer, away from raw meats, poultry, and fish to prevent contamination. Proper storage practices, including maintaining a temperature below 40°F (4°C), can help extend the shelf life of melted cheese, ensuring its quality and safety for consumption.
