How to Dehydrate Bananas in an Air Fryer [Complete Guide]

Dehydrated bananas are a delicious and healthy snack that can be enjoyed on their own or used as a topping for cereal, yogurt, or baked goods.

While dehydrating fruits traditionally requires a food dehydrator, you can also achieve great results using an air fryer. In this article, we will guide you through the step-by-step process of dehydrating bananas in an air fryer, allowing you to enjoy this delightful snack at home.

Why Dehydrate Bananas?

Dehydrating bananas is an excellent way to preserve their natural sweetness and create a portable snack that can be enjoyed anytime, anywhere.

Dehydrated bananas are rich in fiber, potassium, and antioxidants, making them a healthy alternative to processed snacks. Plus, they have a naturally sweet flavor and a chewy texture that is both satisfying and enjoyable.

What You’ll Need

To dehydrate bananas in an air fryer, you will need the following:

  • Ripe bananas
  • Lemon juice (optional)
  • Air fryer
  • Parchment paper or silicone mat
  • Airtight container for storage

Step-by-Step Instructions

Follow these simple steps to dehydrate bananas in your air fryer:

Step 1: Preparing the Bananas

  1. Select ripe bananas that are still firm and free from bruises or blemishes. Ripe bananas will yield sweeter and more flavorful dehydrated slices.
  2. Peel the bananas and slice them into uniform pieces, about ¼ to ⅜ inch thick. Thicker slices will result in chewier dehydrated bananas, while thinner slices will be crispier.
  3. If desired, you can brush the banana slices with lemon juice to prevent browning. This step is optional but can help maintain the bananas’ color.

Step 2: Preparing the Air Fryer

  1. Preheat your air fryer to 135°F (57°C). This low temperature allows the bananas to dehydrate slowly and evenly, preserving their flavor and texture.
  2. Line the air fryer basket with parchment paper or a silicone mat. This prevents the banana slices from sticking to the basket and makes clean-up easier.

Step 3: Dehydrating the Bananas

  1. Arrange the banana slices in a single layer on the prepared parchment paper or silicone mat. Ensure that the slices do not overlap, as this can impede proper airflow and result in uneven drying.
  2. Place the loaded air fryer basket into the preheated air fryer. Close the air fryer and set the timer for 2 hours.
  3. After the initial 2 hours, flip the banana slices to ensure even drying. Continue dehydrating for another 2-3 hours or until the bananas reach your desired level of dryness. Keep in mind that the drying time may vary depending on the thickness of the slices and the humidity in your environment.
  4. Periodically check the banana slices for doneness. They should be slightly pliable and leathery to the touch, with no moisture remaining.

Step 4: Cooling and Storing

  1. Once the banana slices are dehydrated to your liking, remove the air fryer basket from the machine and allow the slices to cool completely. During the cooling process, the banana slices will continue to dry and become crispier.
  2. Once cooled, transfer the dehydrated banana slices to an airtight container or a resealable bag. Store them in a cool, dry place away from direct sunlight.

Tips and Tricks

  • Experiment with different flavor variations by sprinkling cinnamon, cocoa powder, or a pinch of salt over the banana slices before dehydrating.
  • If you want to enhance the sweetness, you can lightly dust the banana slices with a small amount of powdered sugar or drizzle them with honey before dehydrating.
  • Feel free to adjust the dehydrating time based on your personal preference. Some people prefer their dehydrated bananas chewier, while others prefer them crispier.
  • Dehydrated bananas can last for several weeks when stored properly in an airtight container. However, their texture may gradually change over time, becoming softer and less crispy.
  • Don’t throw away overripe bananas! Instead, slice them and dehydrate them for a tasty and nutritious snack.


Dehydrating bananas in an air fryer is a simple and effective way to create a delicious and healthy snack.

By following these step-by-step instructions, you can enjoy the natural sweetness and chewy texture of dehydrated bananas at home. Remember to experiment with flavors and enjoy this nutritious snack on its own or as a versatile addition to your favorite recipes.
