TOP Frequently Asked Questions:

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 then 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 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. They are a good source of digestible fiber too.

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

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?

As long as it takes. Seriously, it depends on how thick you slice them. General rule of thumb: 6 to 12 hours. They'll feel leathery when dried. See full deets further down the page.

Are dehydrated bananas healthy?

Yes, because bananas contain potassium. Potassium is very important for proper brain function, as well as a variety of other critical bodily processes.

Given potassium's far reaching roles in the body and brain, meeting daily intake recommendations (4,700 mg/day) is truly beneficial. Foods like bananas, potatoes, leafy greens, beans and dairy products can all help achieve healthy potassium levels. Here's an overview:

Brain: Potassium allows neurons to more effectively generate electrical signals and communicate with each other. This enhances learning abilities, memory retention, and overall cognitive function. Potassium also helps regulate fluids in the brain.

Heart: Potassium supports healthy blood pressure levels and regulates heart rhythms. It reduces strain on the cardiovascular system.

Muscles & Nerves: Potassium aids muscle contractions and nerve impulse transmission. It prevents painful muscle cramping and spasms. It also reduces fatigue.

Fluids & Electrolyte Balance: Potassium works closely with sodium to regulate hydration and maintain optimal fluid levels in and around cells. This protects organ function.

Kidney Health: Potassium lessens the burden on the kidneys for removing waste products. High potassium diets reduce kidney stone risk as well.

Are dried bananas good for diabetics?

Dried bananas can be enjoyed in moderation by some diabetics, but they should 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 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 introducing dried bananas to see your individual tolerance. Adjust portions accordingly.

While the concentrated sugars give pause, many diabetics can still incorporate small portions of dried bananas as a treat. Moderation, pairing with proteins, blood sugar testing, and working with a dietitian can allow for dried banana enjoyment while managing diabetes appropriately.

Tip: Chill Bananas Before Slicing

Go to grab a bunch—or two—and when you're ready, chill your bananas first before dehydrating bananas.

It makes the bananas much easier to slice—without them going all mushy!

1. Prepare the bananas by unzipping them and slicing them evenly. Not too thick and not too thin.

Don't forget, you can slice your bananas lengthwise too—so you can wrap it around dates and other fruits (and in our recipe Banana Cinnamon Rolls)!

Use your knife and a chopping board, or use a mandoline.

TIP: Chill bananas a short while first for easier slicing—less mushiness—(as mentioned above!)

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.

Are Bananas Easy to Grow?

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.
