How To Dehydrate Bananas in 4 Different Ways

From sun-drying to using the latest kitchen equipment, we included all of the possible ways for you to successfully dehydrate bananas.

Dehydration has been used to prolong the lifespan of fruits and make them travel-friendly especially when you go camping or hiking. 

For the first dehydration method, let’s go with sun-drying!

Method 1: Sun-drying

solar dryer

If you want to save on energy and take advantage of the heat of the sun, you can sun dry them. You can use a solar dryer that you can hang in the sunny area. However, since you are only relying on the heat of the sun, it will take about 6 days to fully dehydrate them. 

The length of the drying time will also depend on the weather. If it rains or gets cloudy the drying time can reach up to 10 days.

Here’s how to prepare bananas for sun drying:


  • 3  of lemon juice
  • 2 cups of water 
  • 3 tablespoons of honey (optional)
  • Strainer
  • Solar dryer
  • 2 to 3 bananas


  1. Mix lemon juice and water in a large bowl. You can add honey to make the banana strips sweeter. However, if you’re looking after your weight you can opt it out. 
  2. Start slicing bananas thinly and let them get soaked in lemon water. Let it sit for 2 to 3 minutes.
  3. Remove the sliced bananas from the bowl and remove extra moisture with tissue paper.  
  4. Place the dried sliced bananas on the strainer inside the solar dryer. 
  5. Hang the solar dryer where there is a full sun and good air ventilation. Let them dry and flip the banana slices after two days. 
  6. Keep on checking the banana slices from time to time just to check if there are no insects inside the solar or if they are drying well. 
  7. Harvest your dehydrated bananas on the 6th day or 10th day when they are already fully dehydrated.
  8. Place them in an airtight container and you can consume them for up to two weeks.

Method 2: Dehydrating Bananas Using An Oven

If you want to save on days of waiting for your bananas to get dehydrated, you can use your oven to cut the drying time.

The best tip to achieve the crunchy or chewy consistency of dehydrated bananas is to cut them uniformly thin. The ideal size is a quarter of an inch for best results.

Here’s how to use your oven to dehydrate your bananas.


  • 2 tbsp. of olive oil
  • 3 baking sheets
  • 3 tbsp. lemon juice
  • 1 ½ cup of water
  • 2 to 3 bananas


  1. Preheat the oven to 175 degrees
  2. Mix the lemon juice and water in a bowl.
  3. Thinly cut the bananas and dip them in the lemon water mixture. Leave them in the mixture for a minute. 
  4. Remove the slices of banana from the lemon water mixture and pat them dry with a tissue paper.
  5. Put the baking sheet in the baking tray and brush it with olive oil.
  6. Place the banana slices neatly on the baking tray and place them in the oven.
  7. Cook them for about 3 hours to dehydrate them right before they get too hard.
  8. Remove the trays from the oven and let them cool down before you store them.
  9. Peel the dehydrated bananas from the baking tray and store them in an airtight container.

Pro tip: If you want to keep the dehydrated bananas chewy, you can cut the banana slices bigger.

Method 3: Dehydrating Bananas Using An Airfryer

If you want the fastest way to dehydrate bananas, you can save on energy by using an AirFryer. However, unlike sun-drying and using an oven, you won’t be able to place them neatly in a baking tray.

The good thing is that with the AirFryer, every banana slice will still be cooked evenly. Here’s how:


  • 2 tbsp. coconut oil
  • cooking brush or pastry brush
  • 2 to 3 bananas
  • 3 tbsp. lemon juice
  • 1 ½ cup of water


  1. Mix the lemon juice with water and place the sliced bananas into it.
  2. Let the banana slices sit in the mixture for 5 minutes.
  3. Remove the banana slices in the mixture and pat them dry with a kitchen towel or tissue paper for 2 minutes.
  4. Place the bananas in the airfryer and brush them with coconut oil.
  5. Open the air fryer and set it to 180 degrees. Occasionally, shake the tray to cook every side of the bananas.
  6. Cook it for about 10 minutes and let it cool down before storing.
  7. Store the dehydrated bananas in an airtight container.

Method 4: Dehydrating Bananas Using a Dehydrator

If you are looking into preserving your food for the long-term, investing in a dehydrator would be best.

If you already have one, you can easily pop in your bananas inside a dehydrator and extend their shelf life. Here’s how:


  • 2 to or more bananas
  • 3 tbsps. lemon juice
  • 2 cups of water
  • 3 tbsps. Honey (optional)


  1. Cut the bananas into thin pieces.
  2. Mix the water and lemon juice in a bowl. You may also add honey to make the dehydrated bananas a little bit sweeter.
  3. Place the sliced bananas in the lemon water mixture.
  4. Pat them dry with a kitchen towel and place them in the dehydrator.
  5. Set the temperature at 135 degrees and set it for 6 to 8 hours. At the 6th hour, you can check if you want to make the bananas crispier or you can settle with a leathery and chewy texture. 

Dehydrated bananas are sweeter and have a crispy to leathery texture. They can be sticky to touch but most likely dry to store in airtight jars.
