How Long Can Mac and Cheese Sit Out?
Mac and cheese can only sit out at room temperature for two hours, or one hour if temperatures are above 90 °F.
It is important to limit the time that food is stored at these temperatures to prevent the rapid growth of food poisoning bacteria.
Mac and cheese can be stored in the fridge for three to five days, and in the freezer for about one to two months.
If mac and cheese has an unpleasant smell, mold growth, discoloration, or a sour taste with abnormal lumps in the sauce, it should be thrown away.
Boxed mac and cheese purchased from the grocery store has a very long shelf life and can last for years if uncooked, but if the cheese powder is discolored, it should also be discarded.
Quick Tips and Facts:
1. Contrary to popular belief, Mac and Cheese left out at room temperature can only be safely consumed for up to two hours. After that, it becomes a breeding ground for harmful bacteria, so it’s best to refrigerate it promptly.
2. The origin of Mac and Cheese can be traced back to Italy, where a similar pasta and cheese dish called “macaroni pie” was first created in the 14th century.
3. Thomas Jefferson played a significant role in popularizing Mac and Cheese in the United States. While serving as the U.S. ambassador to France, he tasted a pasta dish resembling Mac and Cheese and brought the recipe back to America, where it eventually gained popularity.

Room Temperature Limit For Mac And Cheese
Mac and cheese, a beloved comfort food for many, is a delicious combination of macaroni and a creamy cheese sauce. However, it is important to remember that like any perishable food item, it has limits when it comes to being left out at room temperature.
The general rule of thumb is that mac and cheese can only sit out at room temperature for a maximum of two hours. However, it is crucial to note that if the ambient temperatures rise above 90 °F, then this time limit is reduced to just one hour.
The reason behind this time limit is the rapid growth of food poisoning bacteria between temperatures of 41°F and 135°F. By limiting the time that mac and cheese spends at these temperatures, we can minimize the risk of these harmful bacteria multiplying and causing foodborne illness.
- Mac and cheese should not be left out at room temperature for more than two hours.
- If temperatures exceed 90 °F, the time limit is reduced to one hour.

Foodborne Illness And Mac And Cheese
Every year in the United States, there are 48 million cases of foodborne illness, resulting in approximately 3,000 deaths and 128,000 hospitalizations. This staggering statistic highlights the importance of proper food handling and storage. While mac and cheese is generally considered a safe food item, it is not exempt from the risks posed by foodborne pathogens.
The main culprits responsible for foodborne illness are bacteria, such as Salmonella, E. coli, and Listeria. These bacteria can contaminate food if it is not handled, stored, or cooked properly. Therefore, it is crucial to follow recommended guidelines to reduce the risk of foodborne illness:
- Limit the time mac and cheese spends at room temperature
- Ensure it is stored correctly
By practicing proper food handling and storage, we can minimize the risk of foodborne illness.

Proper Storage Of Mac And Cheese In The Fridge
If you have leftover mac and cheese that you want to save for future enjoyment, it is important to store it properly in the refrigerator. By doing this, you can extend its safe consumption period. Mac and cheese can be stored in the fridge for three to five days if it is stored correctly in a shallow, airtight container.
When refrigerating mac and cheese, it is essential to cool it down first before placing it in the fridge. By allowing the dish to cool at room temperature for a short period, you can prevent excess moisture build-up in the container, which could lead to a less desirable texture upon reheating. Additionally, make sure to promptly place the leftovers in the fridge after the initial cooling process is complete.
Freezing And Thawing Mac And Cheese
If you are not planning to consume your mac and cheese within the three to five-day fridge storage window, freezing it is a great option to maintain its quality and extend its shelf life. When stored in the freezer, mac and cheese can last indefinitely. However, for optimal taste and texture, it is recommended to consume frozen mac and cheese within one to two months of freezing.
When it comes to thawing frozen mac and cheese, there are a few methods you can employ. The first and safest option is to thaw it in the refrigerator overnight. This gradual thawing process helps maintain the integrity of the dish. Alternatively, if you’re short on time, you can use the microwave or cold water to thaw the mac and cheese. However, in these cases, it is crucial to consume the thawed mac and cheese immediately to prevent bacterial growth.
- Thaw in the refrigerator overnight
- Use microwave or cold water for quicker thawing
- Consume the thawed mac and cheese immediately to prevent bacterial growth.
Signs Of Spoiled Mac And Cheese
Recognizing Signs of Spoiled Mac and Cheese
As with any food item, it is important to be able to recognize the signs of spoiled mac and cheese to avoid consuming something that could potentially make you sick. When mac and cheese goes bad, it may exhibit distinct signs of spoilage. These include:
- Unpleasant smell
- Mold growth
- Discoloration of the sauce
- Sour taste with abnormal lumps in the sauce
If any of these signs are present, it is best to err on the side of caution and discard the mac and cheese. Consuming spoiled food, especially one that contains dairy, can lead to foodborne illness and its associated symptoms such as:
- Nausea
- Vomiting
- Diarrhea
- Abdominal cramps
Remember, it’s always better to be safe than sorry when it comes to your health.
Shelf Life Of Boxed Mac And Cheese
Boxed mac and cheese has an impressively long shelf life, especially when uncooked. It can last for years in your pantry without going bad, even beyond the listed expiration date.
To ensure its quality, it is important to perform a quick visual inspection of the cheese powder before preparing the mac and cheese. If the cheese powder appears discolored or has an off smell, it is best to discard it.
The shelf life of the macaroni itself may be slightly shorter than that of the cheese sauce mix, but by and large, boxed mac and cheese offers a reliable and long-lasting food option.
In conclusion, mac and cheese is a delectable dish that should be enjoyed safely.
Here are a few important guidelines to follow:
- Limit the time mac and cheese sits out at room temperature.
- Properly store leftovers in the fridge.
