You can make dehydrated watermelon at home with just a watermelon, a knife, and a dehydrator or an oven.
It’s one of the easiest fruit snacks you’ll ever make, and the result is chewy, sweet, and intensely flavorful.
If you’ve been wondering how to make dehydrated watermelon, you’re in the right place.
The process is simple, but a few small tricks make a big difference between soggy slices and perfect watermelon jerky.
In this post, we’ll walk through how to make dehydrated watermelon step by step, including prep, drying times, and storage tips.
Let’s get to it.
How to Make Dehydrated Watermelon Step by Step
Learning how to make dehydrated watermelon starts with the right fruit and a little patience.
Here’s the full process from start to finish.
1. Pick a Ripe, Firm Watermelon
The best dehydrated watermelon starts with a ripe but firm watermelon.
A soft, overripe melon holds too much water and turns mushy during drying.
Look for one that feels heavy for its size and sounds hollow when you tap it.
Seedless varieties work great because you skip the step of removing seeds later.
If you can, choose a watermelon that’s sweet but not dripping with juice.
2. Wash, Peel, and Slice
Rinse the watermelon under cool water and pat it dry.
Cut it into quarters, then slice off the rind and any white pith.
Now slice the flesh into pieces about 1/4 inch thick.
You can cut them into strips, triangles, or thin slabs.
Just keep the pieces uniform so they dry at the same rate.
Thicker slices take much longer and often stay sticky in the middle.
3. Remove Excess Juice
Watermelon is about 92 percent water, which is why dehydrating it takes longer than most fruits.
To speed things up, lay the slices on paper towels and blot the top gently.
Let them sit for about 10 minutes so some moisture drains out.
You can also press them lightly between two clean towels.
This step helps your dehydrated watermelon dry faster and more evenly.
4. Arrange on Dehydrator Trays
Place the slices in a single layer on your dehydrator trays.
Leave a little space between each piece so air can circulate.
If your dehydrator has mesh sheets, use them to keep small pieces from falling through.
Don’t overlap the slices, or they’ll stick together and dry unevenly.
5. Dry at the Right Temperature
Set your dehydrator to 135°F (57°C).
This is the sweet spot for making dehydrated watermelon.
Dry the slices for 10 to 14 hours, depending on thickness and humidity.
Flip them once or twice during drying so both sides dry evenly.
When done, the pieces should be leathery and pliable, not brittle.
They’ll feel slightly tacky but won’t drip any juice when you squeeze them.
How to Make Dehydrated Watermelon in the Oven
No dehydrator? No problem.
You can still make dehydrated watermelon in a regular oven.
Here’s how to do it.
1. Set the Oven to Its Lowest Temperature
Set your oven to its lowest setting, ideally around 135°F to 150°F.
Most ovens don’t go that low, so crack the door open with a wooden spoon to let heat escape.
This keeps the temperature low enough to dry the watermelon instead of cooking it.
2. Use a Wire Rack on a Baking Sheet
Place a wire cooling rack on top of a baking sheet.
Lay the watermelon slices on the rack in a single layer.
The rack lets air move under the slices, which helps them dry evenly on both sides.
3. Bake and Check Every Hour
Dry the slices for 6 to 10 hours, checking every hour after the first few.
Oven drying can be uneven, so rotate the tray and flip the slices as needed.
Your dehydrated watermelon is ready when it’s chewy and leathery with no soft spots.
Tips for the Best Dehydrated Watermelon
These little tricks make your dehydrated watermelon turn out perfect every time.
1. Add a Flavor Boost
Plain dehydrated watermelon is delicious, but you can dress it up.
Sprinkle the slices with a pinch of sea salt, chili powder, or lime zest before drying.
A light drizzle of honey or a dusting of cinnamon also works beautifully.
Just keep the additions light so the slices still dry properly.
2. Watch the Humidity
Humid days slow down drying and can leave your dehydrated watermelon feeling sticky.
If your kitchen is humid, add a couple extra hours to the drying time.
You can also run a fan near the dehydrator to improve airflow.
3. Store It the Right Way
Let the dehydrated watermelon cool completely before storing it.
Keep it in an airtight jar or a zip-top bag with the air pressed out.
Store it in a cool, dark place, and it’ll stay good for 6 to 12 months.
If you notice moisture inside the container, the slices need more drying time.
So, How Do You Make Dehydrated Watermelon?
You make dehydrated watermelon by slicing ripe melon, blotting off excess juice, and drying the pieces at 135°F for 10 to 14 hours.
Learning how to make dehydrated watermelon is really that simple, whether you use a dehydrator or your oven.
The result is a sweet, chewy snack that lasts for months and tastes like summer in every bite.
Grab a watermelon, fire up your dehydrator, and give this easy recipe a try.
Once you know how to make dehydrated watermelon, you’ll never look at this juicy fruit the same way again.
