Why Eat Pesto?

Pesto has it all! You can combine it with just about everything or simply grab a spoon and eat it on its own.

We like it over pasta or slathered on crispy bread, and it makes a supreme dip too. It is especially appetizing in the summertime.

If you have never tried it, it is high time you do! You do not want to be late to this game. It is truly a life-changing food!

You can work it into almost every meal you normally cook.

Besides being incredibly delicious, pesto has numerous health benefits. If you look at the calorie intake only, you will never eat pesto again. However, you would be terribly wrong!

The calories in pesto come from unsaturated fats. What does it mean? 

Well, the unsaturated fats are the so-called healthy fats. They support your heart’s health and provide your body with the energy it needs to get through a busy day. 

For this reason, pesto is an excellent substitute for bad fatty food such as mayo, and various pasta sauces and salad dressings.

If you look at the nutrition label more closely, you will notice that pesto is high in valuable vitamins and minerals too. Most of all, it is rich in Vitamin A and Vitamin C, as well as calcium and iron.

How Long Does Pesto Last In Your Refrigerator? 

Pesto oxidizes as soon as you expose it to air. How can you tell? It turns brown on the surface, or, if you wait too long, throughout. 

It is an unsightly picture, so try to avoid it by all means. How can you do that?

It is simple, never leave your pesto uncovered out in the open. Use a film of plastic wrap to cover the top of the sauce.

The next step is the most important one (and quite logical). You should refrigerate your pesto as soon as you are done using it. It needs to stay refrigerated until you’re ready to use it again too. 

So, the main question is, how long does pesto last in the fridge?

Unfortunately, the answer to this question is not simple. It depends on a variety of factors. First of all, you need to answer the following questions:

  • Is your pesto homemade or bought?
  • Is it fresh, canned, or bottled?
  • How was it prepared?
  • Does it have the best before date?

Once refrigerated, pesto can roughly last from one to three weeks. For more precise information, check out the following table:

How Long Does Pesto Last In Your Freezer?

If you want to be able to use your favorite pesto for a long, long time, you will be pleased to know that it freezes beautifully. 

Many people believe that they can keep their food in the freezer for an unlimited time. They are very wrong! While we agree that it will hardly go bad, frozen food will not remain good to eat forever either. 

It will lose its nutritional value and flavor and even change its consistency. Pesto is no different.

How To Tell If Pesto Is Spoiled?

Due to improper storage or some kind of contamination, fresh or packaged pesto can turn bad sooner than it would normally do. It is crucial to be able to recognize a spoiled pesto before you eat it, or you can get seriously ill.

As we have already mentioned, pesto turns brown when exposed to air.  If the basil leaves have turned brown too, the pesto will not taste the same and is most probably not good to eat. The flavor will be much different also, but we do not recommend trying it out.

Dry packaged pesto will also turn into a brown color when it is past its best by date, or spoiled and rotten. Therefore you should consume it only while it is enticing green.

To avoid all health risks associated with spoiled food, always practice food safety and check expiration or best-by dates on the package!
