Dehydrating bananas is an excellent way to use up those overripe fruits 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!

Your Top Banana Dehydrating Questions—Answered!

How to dehydrate bananas in air fryer?

Simply peel the bananas, slice evenly (1/4 to 1/2 inch thick) - thinner slices will dry faster. Lay them in a single layer in your air fryer basket. Due to the smaller "surface" area inside an air fryer (compared to a dehydrator), you will probably have to work in batches.

Set your air fryer to the lowest temperature, ideally between 120°F and 140°F, and run for 5 to 8 hours. Flip the banana slices over a couple of times during drying.

Dried bananas will feel leathery when done. Follow these proper storage procedures.

Are dried bananas good for dogs?

Yes, in moderation (like everything in life, right?!) It's a nutritious snack for humans and dogs alike, giving us a natural energy boost. Bananas are a good source of digestible fiber too.

As a general guideline, a few dried banana chips 2-3 times per week is an OK addition to most dogs' diets. Break larger chips into bite sized pieces to prevent a choking risk to your dog. And always check with your veterinarian for diet advice that fits your individual dog's needs.

See next question regarding potassium...

Are dried bananas high in potassium?

Bananas are rich in potassium which supports healthy muscles and nerve function in humans and dogs.

Moderation is key as bananas are a high carbohydrate fruit.

How long to dehydrate bananas?

Are dried bananas good for diabetics?

Dried bananas can be enjoyed in moderation if you're diabetic, but be careful with portion sizes. Here are some things for diabetics to consider with dried bananas:

Concentrated carbs and sugars - The dehydration process removes water, concentrating the fruit's natural sugars and carbs that can spike blood sugar levels.

Portion control is key - Stick to about 1-2 tablespoons of dried banana chips per serving. This equals around 15-20 grams of carbs. Pair the banana slices with protein/fat for steadier absorption.

Look for unsweetened - Some prepackaged dried bananas have added sugars or syrups. Check labels and choose unsweetened varieties... or make your own banana chips (keep reading down the page!)

Mind your meter - Monitor blood sugar carefully when adding dried bananas to your diet. Adjust portions accordingly.

Do I need to use lemon juice when dehydrating bananas?

Yes—lemon juice helps prevent browning and gives your banana chips a better color and flavor. You can use fresh lemon juice or bottled, just make sure it’s 100% juice with no added sugars.

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.

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.
