How Long Does Kale Last In The Fridge?
In the fridge, fresh kale will last for 5-7 days. Sometimes, it could last a couple of days longer, all depending on how fresh it is. Therefore, if you’ve bought fresh kale at the farmer’s market, they will most likely last up to a week. Kale sold at the farmer’s market is usually harvested a day before it’s being sold.
Cooked kale will last 3-5 days in the fridge. You’ll need to properly store it though. Just putting them on a plate and putting it in the fridge will not cut it. You’ll probably see it going bad within a day. Cooked kale should be stored in an airtight container or a sealable plastic bag.
As for bagged kale, if it’s unopened, look at the date on the label. It will usually be about 7 to 10 days after you’ve purchased them.

How To Store Kale
Most of the time, you’ll buy kale that is already bagged and prewashed. These kale are pretty much straight forward when it comes to storing them.
Once you get home, put the bag of kale in the fridge and keep them there until you need them.
If you need just some of it, simply remove the amount you need and place the rest back in the fridge. Just remember to keep them stored in the fridge at all times so they’ll remain fresh for a long time.
If you bought fresh kale, like those found at the farmer’s market, they should be stored in the fridge as well.
You have two options when it comes to storing fresh kale in the fridge. One of them is to store fresh kale in the crisper section of the fridge. After you get home, put them into the fridge right away.
Another option would be to put the fresh kale into a plastic bag. Make a couple of holes in the bag for the air to circulate in and out of the bag. This will allow the kale to breathe and prevent them from getting soggy.
Whether fresh kale is stored in the crisper section or on the fridge’s rack, it’s important that you do not wash the kale beforehand. Doing so could cause the kale to spoil quickly. Washing the leafy vegetables will not remove all the moisture from them. The moisture that’s left on the kale will cause the leaves to rotten away when it’s stored in the fridge.
When it comes to cooked kale, they too can be stored in the fridge.
When storing cooked kale in the fridge, they should be stored in an airtight container or a sealable plastic bag.
Once they are placed in the container or bag, make sure to seal it as tightly as possible. If air gets into the bag, it will cause them to become soft and mushy.
Can Kale Go Bad?
Like any other fresh leafy vegetables, kale can go bad. Once the vegetable is harvested, they will start to lose their freshness slowly.
Temperature and storage is the biggest factor for kale going bad. As for temperature, the warmer it is, the faster the kale will go bad. The leaves of the kale plant contain a lot of moisture. When it’s hot, the leaves will start to lose moisture. This will cause the kale to become soggy and wilt.
Where it’s stored is another important factor. Kale needs to be kept in a cool place to retain moisture in its leaves. Therefore, the best place for storing kale would be in the fridge.
How To Tell When Kale Go Bad?

However, the good news is that before kale reached their prime and are no longer safe to eat, they will show signs of black specs. This is a sign that means the vegetable is coming to an end quickly. You can cut the leaves with black specs away and use the rest.
When kale starts to go bad, their leaves will start to lose color. The dark green color will become pale green. The pale green means the kale will only have a day or so left. You’ll either want to use them in a salad or cook them right away. If not, in a couple of days, the leaves will turn yellow and you’ll longer be able to use it.
Another sign is when the leaves become wilted and soggy. This is usually a sign that kale has reached its prime and should be discarded right away.
The last thing to look for is a bad smell. Kale that is bad will have a sulfur smell to it. It will smell bad enough that it will quickly make you throw it away.
How To Keep Kale Fresh Longer
To keep kale fresh for as long as possible, it starts from when you purchase them. The best quality kale will last the longest.
