Homemade Banana Chips

Banana chips are a such a yummy crunchy snack. And the best part is, they are easy to make yourself and much less expensive than buying banana chips at the store.

A lot of people wonder if banana chips are healthy? This is actually a great question because store-bought banana chips are typically fried and contain a lot of ingredients that make them high in fat, sugar, and calories.

When you make banana chips at home, they have the nutrition of bananas without the downsides of being highly processed.  Bananas are a good source of:

  • Fiber- for gut health
  • Carbs – bananas provide a good balance of carbs and fiber to keep you feeling fuller and longer
  • Potassium- helps with muscle movement (great for child athletes)

If you have ripe bananas on your counter right now, these homemade banana chips are definitely a healthy snack option

Ingredients Needed for Banana Chips

Making banana chips at home is so simple because you really only need 2 ingredients!

  • Bananas – you will want to use ripe bananas that are still firm. If they are too ripe, they will be mushy and you won’t be able to slice them very well. If your bananas aren’t ripe enough, the banana chips won’t be sweet.
  • Lemon Juice – if you are using the oven or dehydrator method, you will need lemon juice to prevent the banana slices from turning brown and shriveling during the drying process. The slices will still brown some, but using lemon juice really helps with this.

How to Make Banana Chips

There are three different ways to make banana chips are home. I’m going to teach you the different ways depending on what equipment you have at home.

Oven Method

This method takes the longest but is very hands-off. There are a lot of other oven methods out there, but I have found this method produces the crunchiest banana chip!

  1. Slice. First, slice your bananas as thinly as possible and place them in a bowl. I aim for less than 1/4 inch thick. This is tricky to do if you are just guessing and doing it with a knife. If your bananas are firm enough, you can use a mandolin to make sure your slices are all uniform.
  2. Prepare. Cover the bananas with water, and add lemon juice. Gently stir the bananas to make sure they are all exposed to the lemon juice mixture. Let them sit for a couple of minutes.
  3. Dry. Gently spoon the banana slices out of the bowl and place them on a paper towel to blot excess water.
  4. Arrange. Line a baking sheet with parchment paper, and arrange the banana slices so that they are not touching.
  5. Bake. Set your oven to the lowest temperature it can go. I bake my banana chips at 170 degrees F. They will need to bake for about 5 hours.  After 5 hours, remove bananas and flip them over, so the underside gets crispy.
  6. Crisp. Put the tray back in the warm oven, turn the oven off, and let them sit in the oven overnight.  By morning, your banana chips will be super crispy!

Air Fryer Method

This method is the fastest and will definitely give you super crispy banana chips.

  1. Preheat. Set the temperature of your air fryer to 350 degrees F.
  2. Slice. First, slice your bananas as thinly as possible and place them on a baking sheet (or plate). I aim for less than 1/4 inch thick. This is tricky to do if you are just guessing and doing it with a knife. If your bananas are firm enough, you can use a mandolin to make sure your slices are all uniform.
  3. Prepare. Mix lemon juice and oil together and coat your banana slices.
  4. Arrange. Place the banana slices in a single layer in your air fryer basket or tray. You might have to do this in batches to make sure none of the slices are touching or covering each other.
  5. Cook. Air fry for 10-12 minutes, flipping halfway through, until golden and crispy.
  6. Cool. Remove from the air fryer and let them cool. Repeat with remaining banana slices.

Dehydrator Method

I like this method because it is basically set it and forget it. It does take quite a few hours, but it doesn’t take up oven space and your banana chips don’t really need to be attended to while they are drying.

  1. Slice. First, slice your bananas as thinly as possible and place in a bowl. I aim for less than 1/4 inch thick. This is tricky to do if you are just guessing and doing it with a knife. If your bananas are firm enough, you can use a mandolin to make sure your slices are all uniform.
  2. Prepare. Mix water and lemon juice together. Pour into the bowl with your bananas, and gently stir the bananas to make sure they are all exposed to the lemon juice mixture.
  3. Arrange. Place the banana slices in a single layer on your dehydrator trays. Place the trays on your dehydrator and put the lid on.
  4. Dry. Set the temperature on your dehydrator to 135 degrees F. Your banana chips will need to dry anywhere from 8-12 hours depending on the type of dehydrator you have and how thick your banana slices are. I would recommend checking after 6 hours to determine how much longer your banana chips will need to dry.

How to Dehydrate Bananas

Whether it’s for crunchy dehydrated banana chips or chewy dried banana leathers, there are so many great reasons to dehydrate your own bananas!

While banana bread is the typical go-to when you find that you’ve got a few too many bananas on your hands, another great option is to dehydrate them! Not only are dehydrated bananas soft, chewy, sweet, and loaded with concentrated banana flavor, but if properly stored, can be shelf-stable for upwards of a year! 

There are so many great ways to use dehydrated bananas. Use them as a topping for cereal, yogurt, or oatmeal. Add them to your favorite trail mix. Use banana chips as “dippers” for peanut butter. Serve them on top of burrito bowls like plantains. Or just enjoy them on their own!

Our two favorite versions of dehydrated bananas are the classic chip and the smashed banana leather. The former uses just-barely ripe bananas while the latter uses heavily ripened bananas. So no matter what stage your bananas are at, there’s a method that will work for you. 

So who’s ready to dehydrate some bananas? We’re here to tell you everything you need to know down below.

Sliced bananas on dehydrator trays

Prepping Bananas For Dehydrating

  • Slice the bananas: Using a sharp knife or mandoline, slice the bananas into ¼”-⅜” thick rounds. Try to keep the pieces to a uniform size to help with even drying.
  • For banana “jerky” you can slice the bananas lengthwise into long, ¼” thick slices.

Equipment Spotlight: Dehydrators

If you’re in the market for a dehydrator, we recommend buying one that has an adjustable temperature, which will allow you to dial in the drying temp to give you the best results for individual ingredients. The dehydrator we recommend (and use) most often is the COSORI Premium. You can also check out our best dehydrators post for a comparison of all the dehydrators we’ve used and would recommend.

How To Dehydrate Bananas

Drying bananas is pretty simple! After prepping the bananas and once your counters, equipment, and hands are clean, set up your dehydrator and follow these steps:

  • Arrange the bananas on your dehydrator trays. If you’re using a tray that has large holes, line it with parchment paper or, even better, a mesh liner cut to the size of your tray. Leave space between the pieces to allow air to circulate.
  • Dehydrate at 135ºF (52ºC) for 6-12 hours until the banana is dry and leathery.
  • Depending on your machine, you may need to rotate the trays every so often to promote even drying.

How To Tell When Bananas Are Done

Bell peppers should be hard when they are completely dried. To test, let them cool, then try to bend a few pieces. If they bend, put them back into the dehydrator or oven to dry longer

How To Store

If you’re dehydrating bananas for snacking and plan on eating them within a week or two, you can store them in a sealed container or zip-top bag on the counter or in your pantry. Just let them cool and place them in a sealed container. We like to use these reusable.

However, when properly dried and stored, dehydrated bananas can last up to six months. Here are our tips for long term storage:

  • Let the bananas cool completely before transferring them.
  • Condition: Loosely pack the bananas in a transparent airtight container. Check it daily for a week to check for signs of moisture or condensation, and shake to help prevent the slices from sticking together. If signs of moisture appear, stick them back into the dehydrator (as long as there’s no mold—in that case, toss the batch). After a week, if there are no signs of moisture or mold, you can package them for long-term storage.
  • Store in a clean, airtight container. For longer shelf life, vacuum seal.
  • Use a moisture absorbing desiccant packet if you anticipate opening the container often, or if you live in an area with high humidity.
  • Label the container with the date and any other important details
  • Place the container in a cool, dark, and dry place—inside of a pantry cabinet works well.

How To Make Banana Chips With Dehydrator


  • Bananas: Ripe bananas
  • Pretreating: Fruit Fresh or lemon juice


7 to 9 medium to large ripe bananas will make about 1 ½ quart of dehydrated banana chips.


  • Set up your dehydrator in a safe area.
  • You should also wash and dry each dehydrator tray and plastic mesh liner before each use. I filled 6 trays with sliced bananas.
  • Place a plastic liner on each dehydrator tray and stack the remaining trays nearby, ready to be filled with the banana slices.
  • In a medium-sized mixing bowl mix the Fruit Fresh with water following the directions on the container.
  • Or place 3 tablespoons of lemon juice mixed with 3 tablespoons of water in the bowl if using that.
  • You will need to replenish the Fruit Fresh or lemon juice as you go, depending on how many bananas you will be dehydrating.
  • Set the bowl aside within reach of your work area.


Step 1: Peel and gently slice one ripe banana at a time into thin ¼ inch slices with a sharp paring knife.

Immediately drop the banana slices into the bowl of the pretreatment method you are using and swish them around so they are covered on all sides with the liquid.

Step 2: Transfer the pretreated banana slices to a lined dehydrator tray until the tray is full.

Repeat slicing one banana at a time, dipping into the pretreatment method then arranging the slices on the dehydrator tray until you run out of bananas. Do not let the banana pieces touch or they might stick together.

Step 3 : Once all the trays have been filled place the lid on the dehydrator and turn it on.

If using a dehydrator with an adjustable temperature setting set the temperature to 135 F. degrees.

Step 4: Dehydrate the banana chips for 6 to 12 hours at 135 F. Degrees.

Every 3 to 4 hours rotate the dehydrator trays moving the bottom trays to the top of the dehydrator. Check the banana chips to see how dry they are.

The dehydrating time will vary depending on a number of things.

The type of dehydrator you are using, the temperature of your home, the type of fruit you are drying, and the humidity in the air all play a role in the time it takes to dehydrate fruit.
