Does Butter Expire or Go Bad

Does Butter Expire or Go Bad? Butter is a food that can be used in a variety of ways. You want to make sure it’s good, whether you’re going to put it on your toast or in your cookies. Does Butter Have an Expiration Date? Butter does expire, however it usually does so after a long period of time, especially if stored properly. After the “best by” date, butter should last at least another week. Expired butter usually tastes rancid, and it’s easy to tell when it’s gone bad.

The rest of this article will teach you more about butter, including how to identify if it’s safe to consume and how to store it for maximum shelf life.

When it comes to butter, how long does it last?

Butter will last until it reaches its expiration or “best by” date on the package, and then it should last for another week or two. If you keep your butter in the fridge, it can occasionally survive another couple of months after it has passed its expiration date.

As a result, how you keep your butter has a significant impact on how long it lasts. If you’re not planning on using it right away, it’s a good idea to make sure you’re keeping it carefully so it lasts as long as possible.

It also makes a difference whether your butter is salted or unsalted. Because salt is a preservative, it makes it difficult for bacteria to develop, salted butter tends to last longer. Despite the salt, the butter still contains fat, which will cause it to grow rancid after a while.

What Is the Best Place to Keep Butter?

Butter can be stored at room temperature, but it will degrade quickly and may not even last until the expiration date indicated on the packaging. Butter is best kept in an airtight container in the fridge, where it will last considerably longer.

The lipids in butter undergo oxidation, which causes butter to become rancid. In unsalted or whipped butter, keeping it in the fridge will inhibit the oxidation process as well as the growth of any microorganisms. As a result, butter will last far longer in the refrigerator than on the counter.

It’s fine to keep salted butter at room temperature as long as the temperature in your house is below 77 degrees Fahrenheit. If it’s salted, it’ll last at least two weeks before becoming rancid. When the butter is at room temperature, keep it in an airtight container away from direct sunshine and heat sources (such as an oven).

Another alternative is to keep a small amount of butter on the counter and the rest in the refrigerator. If you like having soft butter on hand to spread on toast but don’t believe you’ll use it up quickly, this is the recipe for you.

How Can You Tell If Your Butter Is Bad?

Fortunately, it’s rather simple to determine when your butter has gone bad. It could have an odd texture, flavour, or smell, as well as discolouration. Mold can grow on spoiled butter, however this is uncommon unless the butter is left out for an extended period of time.

Butter that is still edible should be uniformly white or yellow in hue. If you notice darker or lighter spots on your butter, it’s time to throw it out. If you cut into the butter and don’t detect any browning on the outside, there could be some on the inside as well. In either case, this is a sign that the butter is past its prime.

Butter that has gone bad has a strong rancid and sour flavour, and you’ll be able to tell immediately away that something is wrong. It can also have a foul odour that isn’t what it should be. If something about the flavour or fragrance of your butter doesn’t seem right, toss it out.

Butter that is extremely firm or very soft and stringy is also likely to be harmful. Keep in mind that putting it in the fridge will cause it to harden, while leaving it on the counter will cause it to soften, so use your best judgement when it comes to texture. If the butter has gone bad, the odd texture is usually accompanied by a taste or smell.

Finally, if you keep butter out too long without realising it’s gone rancid, it can mould. If you notice any black or grey patches on the butter, this is mould, and you should discard it right once.

Is it Safe to Eat Expired Butter?

Eating outdated butter is unlikely to harm you, but it is unlikely to be enjoyable (unless the butter is still edible). It’s perfectly OK to consume if it’s still delicious). If the butter has gone rancid, it will taste horrible and be unpleasant to consume, but it should not make you sick most of the time.

Bacteria can’t grow in salted butter because it inhibits their growth. Butter also contains very little protein, which is necessary for bacteria that cause food poisoning to grow. This implies that becoming sick from eating rancid butter is quite rare, and the worst that can happen is a slight stomach discomfort.

If your butter, on the other hand, is mouldy, that’s a another situation. Mold spores can contain bacteria that can make you sick, and eating mouldy butter is definitely not a smart idea.


Butter does go bad after a while, and it’s easy to detect when it’s no longer edible. Although rancid butter will not harm you, it will taste awful, so eating it once it has gone bad is not an option. However, butter will last a long time in the fridge, and you will most likely use it up before it reaches that point.

Whatever you do, we hope that this article has provided you with a better understanding of butter and that you will consider some of these suggestions the next time you purchase a package from the shop.
