What You'll Learn
Soft cheeses should be discarded after two hours
Soft cheeses, such as Brie, Camembert, Queso Fresco, cottage cheese, cream cheese, and mozzarella, are more perishable and susceptible to bacteria and spoilage due to their higher moisture content. Therefore, they should not be left unrefrigerated for more than two hours. If soft cheeses are left out for longer than two hours, the risk of bacterial growth increases significantly, and it is recommended to discard them.
The U.S. Department of Health advises against keeping perishable foods, including soft cheeses, unrefrigerated for over two hours. This guideline is crucial for food safety, as it helps prevent the consumption of spoiled or contaminated food. Leaving soft cheeses out for extended periods can lead to bacterial growth, which can cause foodborne illnesses.
While some sources suggest that hard cheeses, like Cheddar or Parmesan, can be safely left out for longer than two hours, soft cheeses have a much shorter window. This is primarily due to their higher moisture content, which creates an ideal environment for bacterial growth.
To maintain food safety and prevent spoilage, it is best to follow the two-hour guideline for soft cheeses. If soft cheeses have been left out for longer than two hours, it is recommended to discard them rather than risk potential health hazards. Proper storage and handling of cheese are essential to ensure safety and maintain the quality and freshness of the product.
Additionally, it is important to note that the room temperature can also impact the safety of soft cheeses. According to the U.S. Department of Health, if the temperature is above 90°F (32°C), the time limit for leaving cheese out decreases to one hour. Therefore, it is crucial to monitor both time and temperature when dealing with soft cheeses to ensure they remain safe for consumption.

Hard cheeses can be left out for up to eight hours
Hard cheeses, such as Cheddar, Gruyere, Swiss, Gouda, and Parmesan, can be left out at room temperature for up to eight hours and remain safe to eat. This is because hard cheeses have a lower moisture content, which makes them less susceptible to bacterial growth.
It is important to note that while hard cheeses can be safely left out for extended periods, they should still be properly stored when possible. Hard cheeses should be wrapped well and refrigerated or placed in a freezer to maintain their quality and freshness.
When preparing a cheese board or bringing cheese to room temperature for serving, it is recommended to take the cheese out of the refrigerator about one to two hours beforehand. This allows the cheese to reach a temperature closer to our body temperature, enhancing its flavour and texture. At this temperature, the fat molecules in the cheese relax, releasing stronger and more flavourful aromas.
While hard cheeses can be left out for up to eight hours, it is still important to inspect them for any signs of spoilage before consumption. Signs of spoilage in hard cheeses can include a bad smell, slimy surface, dark spots, dryness, cracks, or mould. If any of these signs are present, the cheese should be discarded.
By following these guidelines, you can safely leave hard cheeses out at room temperature for extended periods, ensuring an optimal tasting experience without compromising food safety.

Fresh cheeses only need 30 minutes to reach room temperature
When it comes to cheese, type matters. Soft cheeses like mozzarella, ricotta, cottage cheese, and cream cheese have a higher moisture content and are more perishable, so they shouldn't be left out for more than two hours. Harder cheeses, like cheddar, parmesan, and gouda, have a lower moisture content, making them less susceptible to bacterial growth and able to sit out longer.
But regardless of type, cheese is best enjoyed at room temperature, around 20-22°C (68-72°F). This is because the fat in cheese carries most of the flavour, and when cheese is cold, these fat molecules contract, making it harder to taste the flavour. When cheese is allowed to warm up, the fat molecules relax, releasing strong, flavourful aromas. The texture also improves, becoming softer and creamier.
For hard cheeses, it is recommended to take them out of the fridge about an hour before serving. Softer, riper cheeses like Brie benefit from a longer warm-up time, even up to two hours. However, fresh cheeses only need 30 minutes to reach room temperature. Examples of fresh cheeses include mozzarella, ricotta, and young goat cheese.
It's important to note that leaving cheese out for too long can lead to bacterial growth, especially for softer cheeses. To maintain food safety, the U.S. Department of Health recommends that perishable foods, including soft cheeses, should not be left out at room temperature for more than two hours. Therefore, while bringing cheese to room temperature enhances its flavour, it's important to keep track of time to ensure the cheese remains safe to eat.

Cheese left out overnight may not be unsafe but will lose quality
Cheese is a beloved staple in many households, but it's important to handle and store it properly to maintain its quality and safety. While leaving cheese out overnight may not always result in a food safety issue, it can lead to a decline in quality and increase the risk of bacterial growth, especially in softer cheeses.
The safety window for leaving cheese out varies depending on several factors, including the type of cheese, the temperature of the room, and how the cheese is made or how fresh it is. Hard cheeses like Cheddar, Parmesan, and Swiss have a lower moisture content, enabling them to withstand higher temperatures for longer periods. These cheeses can often be left out at room temperature for up to eight hours without significant safety concerns. However, it's important to check for signs of spoilage, such as bad smells, slimy surfaces, dark spots, dryness, cracks, or mold. If any of these signs are present, it's best to discard the cheese.
On the other hand, soft cheeses like Brie, Camembert, and mozzarella have a higher moisture content, making them more perishable and susceptible to bacterial growth. The U.S. Department of Health recommends discarding soft cheeses left unrefrigerated for more than two hours. Leaving soft cheeses out overnight significantly increases the risk of bacterial growth and spoilage, and they should be discarded.
To maintain the quality of cheese, it is generally recommended to bring it to room temperature before serving. This enhances the flavor and texture, making it softer, creamier, and easier to cut or spread. However, leaving cheese out for extended periods can lead to changes in taste, flavor, and texture. Therefore, it is advisable to return the cheese to the refrigerator after two hours to maintain its optimal condition.
In summary, while leaving cheese out overnight may not always pose a health risk, it can impact its quality. Hard cheeses are generally safer to leave out for longer periods, but it's important to monitor them for any signs of spoilage. Soft cheeses are more perishable and should be discarded if left out overnight. Proper storage, such as wrapping the cheese and maintaining a stable temperature, is crucial to preserving the cheese's freshness and extending its shelf life.

Cheese should be covered when left out to prevent drying
Cheese is a beloved staple in many households, but it's important to handle it properly to ensure safety and optimal flavour. While hard cheeses can generally be left out for longer periods, soft cheeses are more perishable due to their higher moisture content, which encourages bacterial growth. To prevent cheese from drying out and maintain its quality, covering it is essential when left out.
Leaving cheese uncovered can lead to moisture loss, resulting in a dry and crumbly texture. This is especially true for soft cheeses like Brie and Camembert, which should not be left uncovered at room temperature for more than two hours. Hard cheeses, such as Cheddar and Parmesan, can withstand longer periods at room temperature, but even they benefit from being covered to maintain their quality.
When preparing a cheese board, it is recommended to let the cheese sit out for 20-30 minutes before serving to enhance its flavour. During this time, the cheese should be covered but not sealed airtight. This allows the cheese to breathe and prevents the buildup of ammonia and other natural byproducts. A simple way to do this is to place the cheese board over a chilled platter or bowl of ice, providing both a cool surface and a cover for the cheese.
Additionally, the type of wrap used for storing cheese is crucial. Plastic wrap, for example, can be too tight and restrict the cheese's ability to breathe, leading to unwanted bacterial growth. Instead, wax paper or parchment paper is recommended, followed by placement in a plastic bag or airtight container. This combination prevents drying while allowing the cheese to breathe.
In summary, when leaving cheese out, it is essential to cover it to prevent drying and maintain quality. Different types of cheese have varying moisture contents and susceptibility to bacterial growth, so soft cheeses should be treated with extra care. By following these guidelines, you can ensure that your cheese remains safe and flavourful.
