How to Dehydrate Bananas for
Snacks, Baking, and More

If you’ve got bananas ripening faster than you can eat them, dehydrating is your secret weapon. In just a few hours, you can turn fresh bananas into chewy or crispy chips—perfect for healthy snacking, trail mixes, or adding to baked goods.

✅ Quick Answer: How do you dehydrate bananas?
Slice ripe bananas, pre-treat to prevent browning, then dry at 135°F until chewy or crisp. Store in airtight jars for up to a year.

This step-by-step guide shows you how to slice, pre-treat, and dry bananas so they keep their flavor and last for months.

Not only are these dehydrated bananas great for backpacking adventures, but they can also be re-hydrated to make a tasty banana pudding.

Dehydrating them with a dehydrator is an excellent way to use up those overripe bananas that seem to ripen so quickly. The longer you let your bananas "go," the sweeter and softer they become, making them ideal for dehydration.

However, if your bananas are "too far gone," consider using them in smoothies instead—the riper, the better!

Step-by-Step: How to Dehydrate Bananas the Right Way

TIP: Chill bananas a short while first for easier slicing—less mushiness.

  1. Prepare the bananas by unzipping them and slicing them evenly. Not too thick and not too thin. Use a knife and a chopping board, pass on using a mandoline - bananas are too squishy (even chilled) for a mandoline and are easy to chop with a knife!
  2. Grab a bowl and generously spray the banana slices with lemon juice, tossing gently to make sure they are evenly coated. TIP: Use a pump top from a new unused spray bottle; pick one that fits your lemon juice bottle, and look for one that has a long enough plastic tube that will reach the bottom of your lemon juice bottle.
  3. Arrange the sliced bananas on your dehydrator trays, making sure they don't overlap.
  4. Turn on your dehydrator and set the temperature between 125°F and 135°F (or per your food dehydrator's instructions).

  • Dried bananas will feel leathery when fully dried.
  • Drying time: between 6-12 hours.
  • Please remember to rotate your trays, for even drying.

Don't forget, you can slice your bananas lengthwise too—so you can wrap a slice around dates and other fruits (see this recipe Banana Cinnamon Rolls).

Bananas are fairly easy to grow, but they do require some special care. For example, they need to be planted in an area that receives full sun. They also need to be watered regularly.

If you live in an area with a tropical climate, you may be able to grow bananas outdoors all year round.

However, if you live in a cooler climate, you'll need to bring the plants indoors during the winter months, or at the very least, cover them up.
