A Step-by-Step Guide to Dehydrating Bananas in an Air Fryer 

Bananas are a great snack for any time of the day.

But if you’re looking for a way to make your bananas even more delicious and nutritious, try dehydrating bananas in an air fryer!

This is a simple process that can be done in just a few steps.


Here’s the Process of Dehydrating Bananas in an Air Fryer:

Step 1: Preheat the Air Fryer:

The first thing you need to do is preheat your air fryer. Set it to 375 degrees Fahrenheit for about 5 minutes.

This will ensure that the heat will help dry out the banana slices evenly. 

Step 2: Prepare the Bananas:

Once the air fryer has preheated, it’s time to prepare the bananas.

  • Start by slicing the bananas into thin slices – about ¼ inch thick or less.
  • You want them to be as even as possible so they all cook evenly in the air fryer.
  • Once they’re sliced, place them on a plate or baking sheet lined with parchment paper or aluminum foil.  

Step 3: Cook the Bananas 

When you’re ready to cook, place the banana slices directly into your preheated air fryer basket and spread them out so they don’t overlap each other too much.

Then set your timer for 10 minutes and let them cook until lightly golden brown and crispy on both sides (you may have to flip them over halfway through cooking).

Once they are finished cooking, remove your air fryer dehydrated bananas from the heat and let them cool before serving or storing them away for later use! 

Why Are My Air Fryer Dehydrated Bananas Not Crispy?

If your air fryer dehydrated bananas are not as crispy as you’d like them to be, try increasing the cooking time.

You may need to cook them for up to 15 minutes or more until they reach the crispiness you desire.

Additionally, make sure that you’re slicing your bananas evenly so they all cook at the same rate. 

Do I Need to Pretreat Bananas Before Dehydrating Them in an Air Fryer?

Pretreating your bananas before air frying them helps preserve their color and flavor while also preventing oxidation.

The most popular method of pretreatment is blanching or steaming the fruit.

This process involves quickly immersing the bananas in boiling water (or steam) for a few seconds and then submerging them in cold water to stop the cooking process.

This helps remove any existing oils and enzymes that could otherwise cause discoloration or spoiling during dehydration. 

Another common method of pretreating bananas is dipping them in an acid bath solution, such as citric acid or lemon juice.

This creates a barrier between the outer skin of the banana and oxygen, which helps prevent oxidation while also preserving its natural flavor. Additionally, this method gives you a bit more control over how brown or yellow your dried banana chips will be when they are finished dehydrating. 

Do You Need to Soak Bananas in Lemon Juice Before Dehydrating Them in an Air Fryer?

Soaking bananas in lemon juice before dehydrating helps to prevent discoloration.

Bananas naturally turn brown when exposed to oxygen, and that can make the final product look less than appetizing. The acidity of the lemon juice helps slow down this oxidation process which can help keep your dried banana chips looking fresh longer.

Additionally, some people find that adding a small amount of lemon juice enhances the flavor of the dried banana chips by adding a subtle citrusy flavor. 

How To Soak Bananas In Lemon Juice:

The process is very simple and only takes a few minutes of your time before you put your bananas into an air fryer or oven for dehydration.

  • Start by filling a large bowl with cold water then squeeze 1-2 tablespoons of freshly squeezed lemon juice into the water.
  • Give it a stir to mix everything together then add your peeled banana slices and let them soak for 5-10 minutes depending on preference.
  • After soaking, give them a quick rinse with cold water then place them onto parchment paper or reusable silicone sheets before putting them into your air fryer or oven for dehydration. 

Why Are My Air Fryer Dehydrated Bananas Sticky?

Let’s take a look at what could be causing this problem and how to fix it. 

1. The Temperature is Too High:

One of the most common causes of sticky dehydrated bananas is that the temperature of your air fryer is too high.

If you set your air fryer to a higher temperature while dehydrating bananas in an air fryer, it will dry out the fruit faster, but it can also cause it to become too dry and hard on the outside before it has had a chance to fully cook on the inside.

This can leave your banana with an unpleasantly chewy texture instead of being crisp and crunchy. 

2. Humidity Issues 

Another factor that can lead to sticky bananas after dehydrating bananas in an air fryer is humidity levels in your kitchen or pantry.

If there’s too much humidity in the air, it can cause moisture to cling to the surface of your banana slices during dehydration.

This moisture will eventually evaporate away as you continue cooking, but until then it can leave your finished product feeling sticky or slimy. 

The best way to avoid this issue is to make sure that you’re storing and dehydrating your bananas in an area with low humidity levels. 

3. The Fruit is Too Ripe 

Using overripe bananas for dehydrating bananas in an air fryer is another potential issue that might lead to sticky results.

Overripe bananas have more sugar than their firmer counterparts, which means they are more likely to caramelize during cooking and form a thicker syrup-like coating around them while they are being cooked in the air fryer.

To avoid this issue, make sure you only use firm yellow or light yellow bananas for dehydration—avoiding any dark brown spots or overly soft fruits.  

Air Fryer vs Oven for Dehydrating Bananas:

1. Air Fryer:

Air fryers have become increasingly popular over the past few years, and they have revolutionized how we cook many different types of food.

They are particularly well suited for dehydrating bananas because they heat up quickly and evenly, meaning your bananas will dry out evenly without burning.

The air fryer also helps keep the moisture in the bananas, so you don’t end up with dried-out, leathery pieces like you might with an oven. 

2. Oven:

On the other hand, an oven is still a great option if you don’t have an air fryer.

A conventional oven tends to dry out foods more quickly than an air fryer, so you’ll need to make sure to keep an eye on your bananas as they’re cooking.

You’ll also need to flip them regularly so that both sides get equal exposure to heat.

If you want your bananas crispy and crunchy, then using an oven is probably your best bet since it will help draw out more moisture from them than an air fryer would. 

In conclusion, both air fryers and ovens can be used for dehydrating bananas but each method has its own advantages and disadvantages. An air fryer is great for keeping moisture in the fruit while avoiding burnt edges, whereas an oven will help draw out more moisture from the banana which leads to a crispier texture.
