Freeze Dried Fruits

Bananas are easily perishable but don’t dehydrate well. Freeze drying locks in bananas’ color, taste, and nutrition without fancy prepping.

We love freeze-drying bananas because they don’t turn brown like they do in a dehydrator. This process of preservation locks in the taste, flavor, and nutrients of the fruit, unlike any other method. We show you how we process them, so we have tasty, satisfying bananas whenever we need them.


Before we start, let’s get our pieces of equipment ready.

  • Tray
  • Parchment paper
  • Chopping board and knife
  • Freeze dryer

That’s all you need. Life is simpler when you have a freeze dryer, really.

How To Freeze Dry Bananas

  1. Pre-run your freeze dryer so
  2. Line your trays with parchment paper to help keep the bananas from sticking. Bananas have a high sugar content that makes them sticky during freeze-drying.
  3. Peel the bananas and slice them into circular, similar-sized slices.
  4. If you have a little helper that I did, let him line up the bananas on the tray for you. You can keep the bananas close together. That’s fine. They’re not going to expand like Salt Water Taffy.
  5. Close the valve on the side of the freeze dryer and load the tray in.
  6. Close and lock the chamber, making sure it’s airtight.
  7. Press continue.
  8. Once the timer’s done, take out the bananas and enjoy.

How Long Should You Freeze Dry Bananas?

Many variables determine the length of time for freeze drying. These are:

  • The make and model of the freeze dryer
  • What you’re freeze drying
  • The thickness of the food
  • Location of the freeze dryer
  • Climate conditions/season
  • Food temperature (pre-frozen, room temp)

You can play around with the settings until you get it right. For this one, what we did was we added in an extra 4 hours of freeze time plus extra 6 hours of dry time.

Honestly, it’s going to have a lot of trial and error. What you can do is document your process each time you freeze dry. This way, you’ll see where you need to adjust so you can get the ideal settings sooner.


How Do I Know That The Bananas Are Good?

When you check the bananas, every single piece should be dry and hard. No cold, soft, or wet spots.

Biting into it should give you a crunchy, airy texture. They should taste like a banana chip, like the dehydrated ones. Only they’re not chewy and tough. They almost have the airiness of merengue and the same satisfying melt-in-your-mouth experience.

How Thick Should I Slice The Bananas?

You can slice them paper thin if you want banana crisps or chips. You can go thicker; just don’t go above the lip of the tray. For us, we sliced the banana approximately 1/2 or 3/4 inch thick.

Can I Freeze Dry Bananas Whole?

Sure you can! What we like most about freeze-drying is that you can experiment with it and see which method suits you.

One thing, though. It’s going to take longer to freeze dry compared to banana slices. So this means you need to do all the bananas the same way. Otherwise, you’ll end up with inconsistent freeze drying, and that’s not what you want.


How Do You Store The Bananas?

We usually pack our freeze-dried food in Mylar bags since they keep out air, moisture, and light pretty well. We throw in an oxygen absorber (or two for good measure). Then we keep the bags in a place with a temperature not higher than 72°F (22 °C).

For this video, though, we’re going camping so we just threw in the bananas in an air-tight container. Our kids love them, so these are going to be gone in less than a day, haha.

Do You Reconstitute Bananas After Freeze Drying?

We don’t reconstitute the fruit after freeze drying. We find that it doesn’t come out exactly the same.

How Can I Use My Freeze Dried Fruit?

You can grind the bananas in the blender and use it for baby food. It also works well with baking.

For the kids, they just eat them as they are. They’re great for snacking and can be a great compliment to cereals and oatmeal.

If you want an added crunch that turns into a creamy, melt-in-your-mouth sweetness in your ice cream? Go ahead and add your freeze-dried banana slices.

Dogs love them too! They’re great treats for dogs, especially if they’re on a diet.

Tips and tricks

We didn’t pile or layer the bananas because we find that this helps them freeze dry evenly. If you layer them, you’ll have to constantly move them around. Yes, this means constantly taking the tray out of the freeze dryer. You’ll be interrupting the cycle, which prolongs the freeze drying process and gives you inconsistent and unsatisfying results.

Some leave the peel in when they freeze dry. Haven’t personally tried it, but to each her own, I guess.

You can pre-freeze your bananas before putting them in the freeze dryer. This works especially well if you’re in a hot region or your freeze dryer’s in a hot place. It shortens the process considerably and removes the load off your freeze dryer.

Don’t worry about the crystals or bubbles that form when you freeze dry. This is due to the sugar content of the fruit. The more ripe the bananas are, the higher the sugar content.

On this note, better not freeze dry bananas that are too ripe. Someone freeze-dried their batch that’s way too ripe, and the banana slices just exploded.

Freeze drying fruits help ensure you have enough supply without worrying about wastage. If you love bananas but hate the fact that they have a short shelf life, then try this. Freezing them allows you to enjoy the fruit all year long wherever you are without spoilage. No more worrying about browning!

    our power went out for 3 hours and the banana slices are stuck to the parchment paper, any way to suggestions on removing the paper?

    • Hi, Debbie. So sorry to hear about the power outage. Hope all is good with you? Unfortunately, there’s no easy way of removing the paper. They’re stuck there for good. 🙁

    I freeze dried bananas, they were not too ripe. I pre froze them for 2 hrs. Out them in freeze dryer sliced. They foamed up and exploded. What did I do wrong?

    • Hi, Lisa. My goodness, that must have been a shocker. Unfortunately, some do say their bananas create a mess in their freeze dryer. Usually this happens on food that’s got high sugar content on them. Also, 2 hours is not enough pre-freeze time. Harvest Right recommends at least 48 hours of pre-freezing. If you can’t do 48 hours, overnight would do well. Also, once you put food in the freezer, don’t open and close the freezer door. One, pre-freezes food faster. Second is this prevents condensation from forming on the food, which can lead to more moisture and/or large ice crystals.
