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

When learning how to dehydrate bananas, you'll find there are many different types that can be used. However, some varieties are better than others.
For example, Cavendish bananas are the most popular type of banana in the world. They're also the type of banana that is typically used in commercial banana chips.
Other good banana options include plantains, Lady Finger bananas, and Red Dacca bananas. Experiment and see what type of banana you like best!
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.

Bananas are great anyway you slice 'em, but dehydrated bananas are fantastic in granola, banana bread, pudding, cookies... and baby food!
