Bananas are the most popular fruit on the market today. They are tropical fruits that require a specific growing climate to have success.

Knowing how to dehydrate bananas will give you access to them year-round.

Do you know what a supply chain disruption is? It’s when foods and resources are not delivered to an area because a part of the production and delivery process has broken.

If we are talking about SHTF, your access to bananas is going to go away. You can combat that by dehydrating bananas now for long-term food storage. If you do this properly, you can store bananas for decades.

Maybe you’ve grown accustomed to that bright yellow shelf in the produce section. The banana rack that sells these delicious tropical fruits is full each and every week.

The changing environment around us will have an impact on food production, yield, and shipping methods as we move into the future.

We may not always have that massive section at the supermarket to pull fresh bananas from. Let’s hedge our bets and learn how to dehydrate bananas.

How to Dehydrate Bananas

Learning how to dehydrate bananas is easy! The biggest burden will be the processing of those bananas. Most people don’t dehydrate large batches of bananas at a time and that is ok.

Again, this can be a method used to eliminate food waste.

Preparing Bananas for Dehydration

To prep your fruit, you are going to peel the bananas and cut them into rounds. These rounds should be about ¼ – ½ inch thick.

If you like thick banana chips, you might even cut them thicker. There are no rules in this game but the thicker the banana, the longer it will take to dehydrate.

Using wire racks or parchment, you can lay your banana rounds out and then consider which method of dehydration you are going to use.

I have to imagine that the first dehydrated bananas were dried by the sun of Southeast Asia.

Let’s see if we cannot find your perfect dehydrated banana recipe.

Solar Dehydration

Don’t discount the power of the sun. There are incredible products on the market, like The Sun Oven, that will not only dehydrate foods but also cook them!

A simple solar dehydrator will take those overripe bananas and turn them into delicious banana chips with no problem. You can even build a simple DIY solar dehydrator if you are so inclined.

There are also many on the market that would do a great job.

Dehydrating in the sun is going to take a couple of good sunny days in a solar dehydrator. If you have them spread out on racks, you will wind up with great dehydrated bananas.

Remember, you are in control of this process. If the bananas are not as dry or crisp as you like, just leave them in there longer!

Oven-Dried Bananas

So, how long does it take to make dehydrated bananas in the oven? The good news is that its faster than doing it in the sun. Of course, speed isn’t everything but it certainly helps in our fast-paced lives.

You are going to want to set your oven to the lowest setting possible. Most ovens have a position called WARM. If you have a restaurant-style gas oven, you might have a pilot light on at all times. That light will give off enough heat to dry those bananas out.

It is best to dry your bananas on wire racks, but you don’t have them, you can use parchment-lined baking sheets. There is one thing to consider if you go in this direction.

The bananas are going to experience the drying heat on one side of the sheet. The other side will be laying in the liquid that is leaching out of the bananas because of the heat. Flipping those bananas halfway through the process will make a world of difference.

It might seem tedious but it’s a big help.

Dry the bananas for about 8–10 hours and check them for doneness.


If you have a dehydrator at home, then this operation is going to be very simple. If you don’t have one, check out our comprehensive Food Dehydrator Guide to make it easy to figure out which dehydrator is right for you.

Set your dehydrator to 135 degrees and line your racks with the prepped bananas.

Dehydrate them for 10–12 hours or until you reach that state of oneness that you like. If you are trying to make banana chips, you want them completely dried out.

A dehydrator is built for the job and it makes everything easier. If you are committed to dehydrating bananas and other foods, it’s the way to go. Invest in a countertop dehydrator to make this process seamless and simple.

How to Store Dehydrated Bananas

There are a number of ways that you can store your dehydrated bananas once you have finished the process.

It all comes down to what you want to do with those bananas. As I mentioned earlier, most people are not looking to dehydrate 10’s of pounds of bananas at a time.

This means you are likely to wind up with small batches of banana chips to eat or mix into other foods.

That doesn’t mean that you cannot use dehydrated bananas as long-term food storage. If that is your aim, you can certainly use mylar bags and oxygen absorbers to make that happen.

How long Do Dehydrated Bananas Last?

The shelf life of your bananas is going to depend on the type of storage container and the method you decide to use. There are three ways most people will store their dehydrated bananas.


The first is the classic Ziploc bag. If you use these bags to store your dehydrated bananas in your pantry, you will get one good year out of them.

After a year, your banana chips will begin to break down. They will physically get more brittle and begin to turn to pieces and powder.


You can also freeze dehydrated bananas. The dry environment of the freezer is a great environment for dried foods.

The taste and texture of your dehydrated bananas will suffer after a year. They will start to taste like the freezer.

Mylar Bags and Buckets

If you place your bananas in mylar bags with oxygen absorbers and store them in buckets, you will get more than 10 years out of these dehydrated bananas.

Again, you are going to be able to store them this way but you might not need to. You will likely eat these up fast!

Health Benefits of Bananas

chart of the health benefits of bananas

While you might think of South America and the Caribbean, bananas are actually native to Southeast Asia.

There are many types of bananas and the type we eat is known as cavendish. You might have seen the smaller brown varieties, too.

Bananas are so full of nutrition that it’s hard to believe. They contain things like potassium, huge amounts of Vitamin B6, great fiber source, and also Vitamin C.

So, what are the health benefits of bananas?

Digestive Health

While bananas are creamy and smooth in texture, they actually contain two types of fiber that are very beneficial.

The first is pectin which is a naturally occurring fiber in many fruits. It’s also used to make preserves and jams.

The second is called resistant starch. This is the good stuff for gut health. It evades digestion in the small intestine and feeds beneficial bacteria in the lower intestine.

Blood Sugar

The same fiber that nourishes your healthy gut bacteria also slows the digestive process of sugars.

Bananas are obviously not sugar-free. However, they break down slower and will not trigger an insulin spike the way that processed sugar calories can.

Fitness & Weight Loss

When you work out, the energy from your muscles is expended. That energy is called glycogen. After a workout, you need to replace that energy. That is how your muscles begin to recover and get stronger!

A banana is a great food to eat right after a workout. Don’t forget, it is also chock full of vitamins and minerals.

Additionally, eating more bananas and other fruits high in fiber has been linked to low body weight and weight loss.

Heart Health

The banana is known for its potassium content. Potassium is well known to help fight high blood pressure. If you know someone who is fighting high blood pressure, they are likely on some sort of potassium supplement.

A diet high in potassium has been shown to combat heart disease in general.

Banana Peel

Don’t throw away those peels either! They can be used for all sorts of things, Do you know the benefits of banana peels?

They are great for teeth-whitening. Peels can be used to tenderize meats but they are also eaten around the world. Most cultures cook them first to make them more palatable.

The banana peel is a great source of fiber and even contains a mood-enhancing amino acid called tryptophan.

They are also great in the garden soil; they help with bug bite relief and you can even use them to polish things.


Bananas are an absolute nutritional powerhouse. They are a tropical treat that travels from a different hemisphere and we don’t mind because they are so tasty.

Learning how to dehydrate bananas gives you the ability to store them for the long term or eat them in a different way.

There are many reasons to dehydrate bananas. If you take this DIY project on, it will give you another dehydrated fruit to add to those you can dry and store for tomorrow or store for the long term.

Never forget, the process of drying and preserving food is nothing new. It’s merely a process that we have decided to leave behind. Well, it might be time for a resurgence.
