The most common indicator is mold, which may appear as dark spots throughout the pesto.
Additionally, you may notice an off-putting smell, or a change in the texture or color of the basil pesto.
If the pesto has separated and the oil has risen to the top, this can be an indication that it has gone bad.
Its also important to pay attention to the expiration date of your pesto.
If it has been more than a week past its expiration date, it should be discarded.
While there may still be no visible signs of spoilage, the pesto may have already gone bad and should not be eaten.
Freezing basil pesto can also extend its shelf life significantly.
If you have any leftovers, make sure to store them in the freezer.
This will help keep the pesto fresher for longer, and prevent it from going bad.
When youre ready to use it again, simply thaw it out and it should be good to go.

Knowing how to tell if basil pesto has gone bad is important for ensuring that your food is safe to eat and prevent food poisoning.
Moldy Basil Pesto
Mold is one of the most common signs of spoilage in basil pesto, so it’s important to check for it if you suspect your pesto may have gone bad.
Mold appears as fuzzy green or gray patches on the surface of the pesto, and it can be dangerous to consume.
If you spot any mold on your pesto, it should immediately be discarded.
Additionally, it’s a good idea to give the pesto a sniff too, as moldy food often has a sour smell.
If the pesto has a funky smell, that’s a sure sign it should be thrown away.
Off-Putting Smell in Basil Pesto
One of the surest signs that basil pesto has gone bad is an off-putting smell.
Basil pesto should have a fresh, herbal smell, so if you notice any other unpleasant odors, it is likely time to throw it away.
The most common bad smell associated with basil pesto is a sour or fermented smell.
This is a sign that the pesto has gone bad and should not be consumed.
Additionally, if the pesto has a strange or sharp smell, this could indicate that bacteria has started to grow in the pesto and it should be discarded.
It is also important to keep in mind that basil pesto can start to smell slightly different if it has been stored in the fridge for too long.
This is normal and should not be a cause for alarm, but it is still important to check for other signs of spoilage, such as mold or a change in color or texture.
If you can still smell the original herbal scent of the pesto, it should be safe to consume.
If not, it is best to discard it.
Change in Color or Texture of Basil Pesto
One of the most important indicators that basil pesto has gone bad is a change in color or texture.
Fresh basil pesto is usually a vibrant green color, so any discoloration can be a sign of spoilage.
If the pesto has developed any gray or brown spots, it should be discarded immediately.
Additionally, pesto that has separated or become runny is also a sign of spoilage.
If the oil has separated from the rest of the ingredients, it’s a good indication that the pesto has gone bad.
Lastly, if the pesto has become lumpy or thick in texture, it’s likely no longer safe to eat.
Expiration Dates for Basil Pesto
When it comes to knowing if basil pesto is bad, one of the most important factors to consider is the expiration date.
The expiration date on the package of basil pesto is a good indication of how safe the pesto is to eat.
Generally, basil pesto that has been opened should be used within a week; past this point, the pesto may start to spoil and should be discarded.
Additionally, be aware that freezing basil pesto can extend its shelf life significantly, so if you have any leftovers, make sure to store them in the freezer.
When checking the expiration date on your pesto, its important to pay attention to the label.
A date that says sell by indicates the last day the manufacturer recommends selling the product, while a date that says best by indicates the last day the product will retain its peak quality.
If the expiration date has passed, it is best to discard the pesto in order to avoid potential food poisoning.
It is also important to note that expiration dates are not always reliable, especially when it comes to homemade pesto. If you have made pesto yourself, it is best to use it within a week of making it. If you are in doubt, the best advice is to use your senses: if the pesto looks, smells, or tastes off, it is best to discard it.
Freezing Basil Pesto
When it comes to preserving basil pesto, freezing is an effective and easy way to extend its shelf life significantly.
Freezing basil pesto can help reduce the risk of food poisoning and ensure your food is safe to eat.
When it comes to freezing basil pesto, there are a few things you should keep in mind.
First, it is important to freeze the pesto in an airtight container or resealable plastic bag.
This will help keep out any air and moisture, which are both enemies of freshness.
Additionally, make sure to label the container or bag with the date so you know when it was stored.
You should also be sure to use the pesto within six months of freezing it.
When it comes time to use the frozen pesto, simply thaw it in the refrigerator overnight.
You may also be able to thaw it in the microwave, but this can affect the taste and texture.
Once thawed, make sure to use the pesto within a few days, and be sure to discard any that looks or smells off.
By freezing basil pesto, you can ensure that it stays fresh and safe to eat for an extended period of time.
Just be sure to follow the above tips to ensure it stays as fresh as possible.
