Macaroni and cheese is a beloved comfort food for many, but it's important to be aware of its shelf life to avoid food poisoning. The shelf life of macaroni and cheese depends on various factors, such as the type of macaroni and cheese, how it is stored, and individual sensitivity to spoiled food. Dehydrated or boxed macaroni and cheese can last for a year or two past its expiry date, while cooked macaroni and cheese will typically last 3 to 5 days in the refrigerator and up to two months in the freezer. Sensitivity to food spoilage also varies, so it is essential to use the sniff and texture tests to determine if your macaroni and cheese has spoiled.

What You'll Learn
How long does cooked macaroni and cheese last in the fridge?
Cooked macaroni and cheese can be kept in the fridge for 3 to 5 days. However, some sources suggest that it is only good for up to 3 or 4 days, and one source states that it can be kept for up to a week. After this time, the risk of harmful bacteria developing increases. To maximise the shelf life of cooked macaroni and cheese, it should be refrigerated within two hours of cooking and stored in shallow, airtight containers.
When determining whether cooked macaroni and cheese has spoiled, it is important to examine its smell, taste, and texture. If it smells bad, has an unexpected texture, or looks like it's growing mould, it should be discarded. Reheating food will kill off harmful bacteria, but if toxins have already been produced by bacteria, the food will no longer be safe to eat.

What are the signs that macaroni and cheese has spoiled?
Macaroni and cheese is a delicious comfort food, but it can go bad if not stored properly or consumed within a few days. Here are some signs that your macaroni and cheese has spoiled:
Changes in Appearance
If your macaroni and cheese has been sitting in the fridge for a while, check for any visible signs of spoilage. Look out for any fuzz or mould growing on the surface. Mould can appear in various colours, including blue, green, or white. If you spot any mould, discard the entire dish immediately as it indicates bacterial growth.
Odour
Use your sense of smell to detect spoilage. If the macaroni and cheese has an off-putting or rancid odour, it has likely gone bad. Bacterial growth can produce unpleasant smells, so trust your nose if something doesn't smell right.
Texture Changes
Spoiled macaroni and cheese may exhibit changes in texture. If the surface has become slimy or sticky, it's a clear indication of spoilage. The slime is often a result of bacterial growth and is unsafe to consume.
Colour Changes
Check for any discolouration in your macaroni and cheese. If the cheese sauce has turned from its usual creamy colour to a darker or brownish hue, it may be a sign of spoilage. This discolouration could be due to oxidation or bacterial growth.
Taste
While it is not recommended to taste spoiled food, sometimes the taste can indicate spoilage. If the macaroni and cheese tastes sour, bitter, or "off," it has likely gone bad. Trust your taste buds if the flavour seems abnormal.
To prevent spoilage, it is best to consume macaroni and cheese within 3 to 4 days of refrigeration. You can also freeze it to extend its shelf life. Always store leftovers in airtight containers and reheat thoroughly before consumption. Remember, when in doubt, it's better to discard the food to avoid any potential health risks.

How long does boxed macaroni and cheese last?
Boxed macaroni and cheese can last for quite a while, especially if it's stored properly. The first thing to consider is whether the box has been opened or not. If it hasn't, an unopened box of macaroni and cheese will last for up to two years if stored in a cool, dry spot.
Once the box is opened, the contents should be stored in an airtight container if the packaging gets damaged. Stored like this, it will last for up to two years, but the cheese flavour will start to degrade over time. If the cheese powder has changed colour or clumped up too much, or if the uncooked pasta feels moist, it should be discarded.
If you've cooked the macaroni and cheese, it will last in the fridge for three to four days. If you're not going to eat it within two hours of cooking, it should be stored in the fridge in an airtight container to keep it fresh. Reheating food will kill off harmful bacteria, but if there are toxins present, no amount of cooking will make it safe to eat. If it smells bad or has an unexpected texture, it should be thrown away.
It's worth noting that the dates on the box are more of an indication of when the food is in its prime, rather than a hard-and-fast expiration date. Food banks suggest that boxed macaroni and cheese can last at least a year past its best-when-used-by date.

Can you eat expired macaroni and cheese?
Macaroni and cheese is a comfort food for many, but it's natural to wonder if you can eat it after its expiry date. The short answer is yes, you can eat expired macaroni and cheese, but there are some important considerations to keep in mind.
Firstly, it's essential to distinguish between cooked and uncooked macaroni and cheese. Cooked macaroni and cheese, when properly stored in an airtight container, will typically last 3 to 5 days in the refrigerator. If you want to extend its shelf life, you can freeze it, and it will maintain its best quality for about 1 to 2 months. On the other hand, uncooked boxed macaroni and cheese can be safe to consume even past its expiry date, usually up to a year, as long as the packaging is intact.
When it comes to cooked macaroni and cheese, the sniff and texture tests are reliable indicators of spoilage. If it smells bad or has a slimy surface, it's best to discard it. Reheating can kill off harmful bacteria, but if bacteria have produced toxins, cooking won't make it safe to eat. For uncooked boxed macaroni and cheese, pay close attention to the cheese flavouring, as it is more prone to spoilage than the dehydrated pasta. If the flavouring powder has changed colour, clumped excessively, or the pasta feels moist, it's best to discard the package.
While it's generally safe to consume expired macaroni and cheese within a reasonable timeframe, it's important to trust your senses. If something seems off in terms of smell, taste, or appearance, it's better to err on the side of caution and discard the food. Remember, expiry dates are not always a hard-and-fast rule, but they are an indication of when the food is in its prime.
In conclusion, you can eat expired macaroni and cheese, but always exercise caution and common sense. Trust your senses, and if in doubt, throw it out.

How to store leftover macaroni and cheese
Macaroni and cheese is a delicious meal, but it's often hard to get the portions just right, and you may be left with leftovers. Here's how to store leftover macaroni and cheese to keep it tasting great and safe to eat.
Firstly, it's important not to let your macaroni and cheese sit out for more than two hours, or it may start to spoil. You don't have to let it cool down before putting it in the fridge, but it's best to let it cool almost completely. Portion it out into individual servings, and store them separately in airtight containers. This will help keep the food fresh and make it easier to reheat just what you need.
In the refrigerator, your leftover macaroni and cheese will last for around three to five days. Be sure to store it in the back of the fridge, which is the coldest part, and keep cooked food above raw food to avoid cross-contamination.
If you can't eat your leftovers within that time, you can freeze them. Transfer the macaroni and cheese to an airtight container, clearly label it with the date, and put it in the freezer. It will last for two to three months in the freezer, but the sooner you eat it, the better, as it may start to lose its flavour.
To reheat your macaroni and cheese, you can use the microwave, oven, or stovetop. For the best results, add a splash of milk or a pat of butter to keep it creamy, and consider adding extra cheese or seasonings. If you're reheating from frozen, let it thaw in the refrigerator first, which can take several hours or even overnight.
