If you have frozen fruits that are filling up your freezer, the time will come when you need to make room for other things. In this situation, you’ll be looking for ways to remove some of the fruits out of the refrigerator.

This leads to the question, can you dehydrate frozen fruit? Fruit dehydration is best done during peak season when fruits are plentiful, and may even save you money. 

If you’re trying to find out how to preserve fruits more effectively, you’ve probably asked yourself whether you can dehydrate them. If that’s the case, this article is for you.

Can You Dehydrate Frozen Fruit?

Yes, it is possible to dehydrate frozen fruit. Blueberries, when frozen, are one of the fastest frozen fruits to dehydrate.

It’s essential to keep in mind, however, that some fruits cannot be dehydrated. Avocados are one example. You need to ensure that the fruits you intend to dehydrate are suitable for this process. 

How to Dehydrate Blueberries

You might think that frozen fruits have to be defrosted and drained before being dehydrated. However, this is an additional step that isn’t always required. For certain fruits, dehydrators can be used without the need to defrost.

Scatter the frozen blueberries out on dehydrator trays in a single layer. Set the dehydrator to 125-130°F or according to the manufacturer’s instructions. 

Based on the blueberries’ size, the drying procedure can take between 15 to 30 hours. If you feel impatient and want to accelerate the drying process, don’t raise the temperature. Although you might expect the blueberries to dry faster, it can actually cause uneven drying. 

For the best outcome from the dehydration process, employ the slow, steady method. Keep the frozen fruit stored in an airtight container in a cold, dry location and away from direct sunlight.

Blueberry Dehydration Using an Oven

Can you dehydrate frozen fruit using an oven? Absolutely! You can also use an oven to dehydrate frozen fruits if you don’t have a dehydrator. 

This approach works great, but it consumes more energy than a dehydrator, so keep that in mind. It’s really no different than drying fresh fruits. 

If you want to dehydrate blueberries, the first step is to cover a cookie sheet using parchment paper. Then, spread your blueberries out on the sheet. You can thaw the berries before putting them in the oven if you’d like, but it is not required.

Make sure the blueberries are free of any leaves or stems and are clean. Keep the blueberries in the oven for 10 hours, baking at 135°F. 

If your oven doesn’t heat uniformly, rotate the trays to ensure that they all receive the same amount of heat. Alternatively, you can heat the blueberries for 7 hours at 200°F if you’d like to speed up the process. 

You’ll need to keep an eye on them to avoid burning. A thermometer can come in handy when checking your oven temperature and making any necessary adjustments.

Rehydrating Dried Blueberries

You can quickly rehydrate dried blueberries for use in smoothies, recipes, and other applications. Fill a clean basin halfway with room temperature water and add the dried berries. 

After roughly 30 minutes, the blueberries should have absorbed the water and be ready to use. Any surplus water should be drained. Refrigerate the reconstituted blueberries until you are ready to use them. 

It’s essential to use the blueberries in a few days, as they’re more susceptible to spoilage.

Dried blueberries are nutrient-dense and have numerous health advantages, so you should incorporate them into as many dishes as possible.

Can Frozen Pineapple Be Dehydrated?

Dehydrating frozen pineapple is possible. You have two choices: dehydrate it immediately or defrost it beforehand. Here are the steps to follow to dehydrate frozen pineapple:

Thinly slice the pineapple into 1/8 to 1/4-inch thick slices. Ensure the slices are all the same size. Put the slices in one layer on mesh trays. Before putting them in the dehydrator, check to confirm that they don’t overlap.

Dehydrate the pineapple slices at 135°F for 30 minutes or until they are dry and leathery. The dehydration procedure will take 8-12 hours for smaller pieces.  Thicker and larger pieces will need 12-14 hours. 

Let them cool down entirely before putting them in an airtight container for storage. Keep the container somewhere that is cool and dry. Dehydrated frozen fruits can last up to a year if they are stored correctly. However, if you want to get the most out of it, consume them within six months.

Can Frozen Elderberries Be Dehydrated?

Yes, frozen elderberries can be dehydrated. The entire dehydration procedure is straightforward. You can follow these steps:

  • Arrange the frozen elderberries on a parchment paper-lined dehydrator screen. Ensure they’re all in one layer and not stacked on top of one another. Check to confirm that there aren’t any stems or leaves.
  • Dehydrate the elderberries at 125-135°F in a dehydrator. It will take roughly 15-20 hours to complete this task. The moisture content in the berries will determine how long they need to dry. It’s critical to check on the elderberries after several hours to ensure that everything is going smoothly.
  • Elderberries should be properly dried after roughly 15 hours. Store them in an airtight container after you’ve cooled them completely. 

Can Frozen Cherries Be Dehydrated?

Frozen cherries can be dehydrated. The dehydration method is identical to that of dehydrating frozen blueberries. Simply cut the cherry in half and lay the pieces on a parchment-lined dehydrator tray. If you prefer sweeter dried cherries, sprinkle sugar on the slices. 


If you have been wondering, “can you dehydrate frozen fruit,” you now know that you can. However, there is a catch. Avocados, for example, are unable to be dehydrated. Try to research your fruit before dehydrating any to ensure that it is safe and appropriate.
