Select Ripe Bananas

To dehydrate bananas, select ripe bananas with a few brown spots, indicating their sweetness. Avoid overly ripe, mushy bananas. These bananas should still be firm enough to slice evenly. The ideal ripeness strikes a balance between sweetness and texture for the best results in the dehydration process. It’s the first tip on How to Dehydrate Bananas.

Prepare Lemon Juice Solution (Optional)

Creating a lemon juice solution is optional but helps prevent banana slices from browning during the drying process. To prepare it, mix 1 tablespoon of lemon juice with 1 cup of water in a bowl. The acidity in the lemon juice helps counteract oxidation, which causes the bananas to turn brown.

Dip the banana slices into this solution briefly before placing them in the dehydrator or oven. This step enhances the appearance of the dehydrated bananas and helps maintain their natural color. It’s the second tip on How to Dehydrate Bananas.

Peel and Slice

After selecting ripe bananas, peel them and slice into even pieces. Aim for slices around 1/4 to 1/2 inch in thickness. An even thickness ensures consistent drying. You can choose to cut the bananas into rounds or strips, depending on your preference.

Use a sharp knife and a cutting board to make this process easier. If you prefer to prevent browning, you can dip the slices into a lemon juice solution, which helps maintain their color during dehydration. Once sliced, they are ready for the drying process. It’s the third tip on How to Dehydrate Bananas.

Dip in Lemon Juice (Optional)

Dipping banana slices in a lemon juice solution is an optional step that helps prevent browning during the drying process. To do this, prepare a mixture by combining 1 tablespoon of lemon juice with 1 cup of water in a bowl. The acidity in the lemon juice inhibits oxidation, which causes the bananas to turn brown.

Gently dip each banana slice into this solution and let them drain briefly before placing them on the dehydrator trays or baking sheets. This step preserves the natural color of the banana slices, making them more visually appealing in the finished dehydrated product. It’s the fourth tip on How to Dehydrate Bananas.

Arrange on Dehydrator Trays

Once you’ve prepared your banana slices, it’s time to arrange them on the dehydrator trays. Place the slices in a single layer, ensuring they don’t overlap. Leave some space between each slice to allow for proper air circulation, which is essential for even drying.

Proper spacing helps prevent the slices from sticking together during dehydration. Follow the manufacturer’s instructions for your specific dehydrator, as they may provide guidance on the best tray placement and load capacity. Once the trays are loaded with banana slices, you’re ready to set the dehydrator’s temperature and begin the drying process, typically at around 125°F (52°C). It’s the fifth tip on How to Dehydrate Bananas.

Set Dehydrator Temperature

To effectively dehydrate banana slices, follow the manufacturer’s instructions for your specific dehydrator model. In most cases, you’ll want to set the temperature to around 125°F (52°C) for bananas. This moderate heat helps remove moisture from the fruit while preserving its flavor and nutrients.

Be sure to refer to the dehydrator’s user manual for the exact temperature settings and recommended drying times, as they can vary depending on the brand and model. Proper temperature control is crucial to achieve the desired results and ensure that your banana slices are evenly and thoroughly dehydrated.


Dehydrating bananas involves removing their moisture to create a tasty, shelf-stable snack. Here’s a brief guide:

  1. Prepare Bananas: Select ripe, but not overly ripe, bananas. Peel and slice them into uniform pieces, approximately 1/4 to 1/2 inch thick.
  2. Optional Lemon Juice Dip: To prevent browning, briefly dip the banana slices in a mixture of 1 tablespoon of lemon juice and 1 cup of water.
  3. Arrange on Dehydrator Trays: Lay the slices in a single layer on dehydrator trays, leaving space for proper air circulation.
  4. Set Temperature: Follow your dehydrator’s instructions, but the typical temperature for bananas is around 125°F (52°C).
  5. Dehydrate: Allow the dehydrator to run for 6 to 12 hours, or until the banana slices become dry and leathery.
  6. Store: Once dried, cool the slices and store them in an airtight container for a delicious, long-lasting snack.

Check for Doneness

Periodically check the banana slices for doneness during the dehydration process to ensure they are drying evenly. The exact drying time may vary based on the thickness of the slices and your specific equipment. To check for doneness:

  1. Inspect Texture: Examine the banana slices. They should feel dry to the touch and have a leathery, pliable texture. There should be no moisture left in them.
  2. Test for Stickiness: Gently touch the slices. They shouldn’t feel sticky or tacky. If they do, they need more drying time.
  3. Bend Test: Try bending a slice; it should bend without breaking but not be too flexible.
  4. Color: The slices should retain their natural color, and if you used the optional lemon juice dip, they should not be overly brown.

Remove any slices that are fully dried and leave the others to continue dehydrating as needed.


In conclusion, dehydrating bananas is a straightforward and rewarding process that allows you to enjoy this delightful fruit year-round. Whether you’re creating a healthy snack, adding a burst of flavor to your recipes, or reducing food waste, dehydrated bananas offer a versatile solution.

By following the steps outlined in this guide and investing a little time, you can savor the natural sweetness and nutritional benefits of bananas in a convenient, shelf-stable form. So, get started on your dehydrating adventure and discover the lasting joy of homemade dehydrated bananas.

Do I have to use a dehydrator, or can I use an oven?

While a dehydrator is the most efficient and convenient option, you can also use an oven to dehydrate bananas. To do this, set your oven to its lowest temperature (usually around 170°F or 75°C) and follow the same preparation and drying process, but keep a close eye on the bananas to avoid over-dehydrating.

How long do dehydrated bananas last?

When stored in an airtight container in a cool, dry place, dehydrated bananas can last for several months to a year. It’s essential to ensure they are completely dry before storing to prevent moisture-related spoilage.
