How to Dehydrate Fruit
Wash and slice fruit evenly, dip cut fruit in lemon water to limit browning, and dry at about 135F (57C) until leathery, from a few hours to 12+ hours depending on the fruit and thickness. Cool and store airtight.
Fruit is the friendliest thing to dehydrate: naturally sweet, forgiving, and useful as snacks, leather or baking add-ins. The method is the same across most fruit, only the timing changes.
Prep and pretreat
Wash, then slice evenly, uniform thickness is the single biggest factor in even drying. For pale fruit that browns (apples, pears, bananas), dip the slices in water with a little lemon juice, then drain. This is optional and purely for colour.
Temperature and timing
Dry most fruit at about 135F (57C). Times vary widely by fruit, thickness and machine:
| Fruit | Approx time at 135F | Guide |
|---|---|---|
| Apple slices | 6–12 hours | Apples |
| Banana slices | 6–12 hours | Bananas |
| Berries | 10–18 hours | Halve or check skins |
| Fruit leather (puree) | 6–12 hours | Use solid sheets |
Doneness and storage
Test a cooled piece, it firms as it cools. Aim for leathery (or crisp for chips) with no wet spots. Cool fully, then store airtight and dark; vacuum sealing pushes shelf life to the top of its range.

Frequently asked questions
What temperature to dehydrate fruit?
Around 135F (57C) suits most fruit. Even airflow and uniform slices matter more than the exact number; judge by texture, not the clock.
Should I pretreat fruit before drying?
For pale fruit like apples and pears, a quick lemon-water dip limits browning. It is cosmetic, browned fruit is safe, but it makes a nicer result.
How do I know dried fruit is done?
Cool a piece, then check: leathery and pliable with no beads of moisture. For chips, it should be crisp. Condition the batch to catch hidden moisture.
