You can dehydrate celery in a food dehydrator, and it’s one of the easiest ways to preserve this crunchy vegetable for months.
If you’ve been wondering how to dehydrate celery in a food dehydrator without ending up with brown, flavorless sticks, you’re in the right place.
Dehydrating celery in a food dehydrator keeps that distinct celery flavor locked in while removing all the water that would otherwise cause it to spoil quickly.
In this post, we’ll walk through exactly how to dehydrate celery in a food dehydrator, how long it takes, and how to store your dried celery so it stays fresh.
Let’s dive in.
How to Dehydrate Celery in a Food Dehydrator
To dehydrate celery in a food dehydrator, you basically need to wash it, chop it, and load it into the machine on the right setting.
Here’s how to dehydrate celery in a food dehydrator step by step so you get the best results every time.
1. Pick Fresh, Crisp Celery Stalks
The quality of your dried celery starts with what you put in the dehydrator.
Choose firm, crisp stalks that snap when you bend them.
Avoid celery that’s limp, rubbery, or starting to turn brown because dehydrated celery made from tired stalks tastes bland and woody.
If you’re dehydrating celery to reduce food waste, slightly wilted stalks still work, but fresh ones always give the best flavor.
2. Wash and Dry the Celery Thoroughly
Rinse each stalk under cool running water to remove dirt, grit, and any lingering pesticides.
Pay attention to the grooves along the outside where soil likes to hide.
Once washed, pat the celery dry with a clean towel or paper towels.
Excess surface water means longer drying times when you dehydrate celery in a food dehydrator, so don’t skip this step.
3. Chop the Celery into Even Pieces
Consistency is everything when you dehydrate celery in a food dehydrator.
Cut the stalks into pieces that are roughly the same size so everything dries at the same rate.
Slices about 1/4 to 1/2 inch thick work great for soups and stews.
If you plan to rehydrate celery for snacking, you can leave longer sticks.
Just remember that thicker pieces take longer to dry, and uneven pieces leave you with some bits that are bone dry and others still chewy.
4. Blanch the Celery (Optional but Recommended)
Blanching is optional, but it helps dehydrated celery keep its color and flavor longer.
To blanch, drop the chopped celery into boiling water for about 2 to 3 minutes.
Then immediately transfer it to an ice water bath to stop the cooking process.
Drain and pat dry before loading the dehydrator trays.
If you’re short on time, you can skip blanching, but your dehydrated celery may lose some of its vibrant green color over time.
5. Arrange the Celery on Dehydrator Trays
Spread the celery pieces in a single layer on each tray.
Make sure the pieces aren’t touching or overlapping.
Overlapping pieces trap moisture and slow down the drying process, which can lead to mold later on.
If your dehydrator has mesh sheets, use them for smaller pieces so nothing falls through the cracks.
6. Set the Right Temperature and Time
Set your food dehydrator to around 125°F to 135°F (52°C to 57°C).
At this temperature, celery usually takes about 6 to 10 hours to fully dry.
The exact time depends on how thick your pieces are, how humid your kitchen is, and the model of your dehydrator.
Check the celery every couple of hours after the 5-hour mark.
How Long Does It Take to Dehydrate Celery in a Food Dehydrator?
Celery takes roughly 6 to 10 hours to dehydrate in a food dehydrator at 125°F to 135°F.
Thin slices can be done in as little as 4 to 6 hours, while thicker sticks may need up to 12 hours.
The best way to know when your celery is done is by testing it, not by watching the clock.
Properly dehydrated celery should feel brittle and snap when you bend it.
It should not feel leathery, bendy, or cool to the touch.
If it’s still flexible, keep drying and check again in another hour.
How to Store Dehydrated Celery
Once your celery is fully dry, let it cool completely at room temperature.
Then store dehydrated celery in an airtight container, glass jar, or vacuum-sealed bag.
Keep it in a cool, dark, and dry place like your pantry.
Properly stored dehydrated celery lasts anywhere from 6 months to a year.
For even longer shelf life, you can store it in the freezer.
If you notice moisture forming inside the container, the celery wasn’t dried enough, so return it to the dehydrator for another hour or two.
So, How Do You Dehydrate Celery in a Food Dehydrator?
You dehydrate celery in a food dehydrator by washing, chopping, optionally blanching, and drying it at 125°F to 135°F for 6 to 10 hours.
Once the celery is brittle and snaps easily, it’s done.
Learning how to dehydrate celery in a food dehydrator is a simple skill that saves you money and cuts down on food waste.
Whether you toss it into soups, stews, or casseroles later, dehydrated celery brings that fresh celery taste right back to life.
