How to Make and Use Freeze-Dried Celery
Celery is a nutritious vegetable that is simple to grow (learn how here). I grow celery yearly in my cool-season garden and often have abundant fresh celery at harvest time. Freeze-drying is my favorite way to preserve celery’s flavor and nutrition. Learn how to make and use freeze-dried celery and enjoy its benefits for up to 20 years.
What We’ll Cover:
Benefits of Consuming Celery
Celery is often referred to as a superfood, and it’s easy to see why. Research has shown that some benefits of consuming celery include:
- Lowering high blood pressure: Celery contains compounds that can help relax the blood vessels, lowering blood pressure levels.1
- Cancer prevention: Celery is rich in antioxidants, which may help prevent cellular damage and reduce cancer risk.2
- Boosting digestion: The high fiber content of celery can promote bowel movement and reduce the risk of constipation.3
- Reduced inflammation: Certain compounds in celery have been shown to have anti-inflammatory effects, which may help reduce inflammation in the body.4
- May improve skin health: Celery contains vitamin C and other antioxidants that can help reduce skin damage caused by free radicals.5
Freeze-drying is known to preserve the nutritional content and quality of food, so you can enjoy these benefits for years.6

Don’t Have a Freeze Dryer?
Purchasing a freeze dryer is undoubtedly an investment. My freeze dryer runs almost nonstop, and I’m grateful to have one. I have the medium-size freeze dryer with the premier pump from Harvest Right.

Why Freeze Dry Home-Grown Celery?
Although celery is very nutritious, conventionally-grown celery can be high in pesticides. Preserving the abundant harvests of your homegrown celery allows you to reap all the benefits of consuming celery without the possible pesticide risk.7
Because freeze-dried celery can last for more than a year, it’s an excellent way to preserve your harvest, reduce waste, and build a flavorful food storage straight from your garden. Below are simple, practical ways to use freeze-dried celery in your kitchen year-round.
How to Freeze Dry Celery
Feeze-drying celery is quite simple. All you need is some fresh celery, a freeze dryer, and an airtight container or vacuum sealer bag for storing them when they’re done.
I freeze dry celery stalks and leaves. The processing times for leaves and stalks are different, so process them separately.
- Cut the stalks/leaves into uniform sizes and place them on freeze dry trays up to the top of the tray.
- Follow your freeze dryer’s instructions to process them.
- Freeze dry until completely dry. Once they are crisp enough to snap when bent gently in half, they are ready to be stored away.
- Using a blender, process into powder or leave whole.
- Immediately after freeze-drying, place the dried stalks into an airtight container or mylar bag with an oxygen absorber for storage until ready for use.
A note about dehydrating:
Dehydrating celery also works as a preservation method. You may lose more nutritional value when dehydrating, however.
How To Use Freeze-Dried Celery
Use Freeze-Dried Celery and Celery Leaves Whole
To rehydrate freeze-dried celery, place the celery in a bowl covered with cool water. Cool and let sit until desired consistency is reached. Use as you would fresh in recipes.
To use in soups or stews, add freeze-dried vegetables to the pot while cooking. This works especially well in my Make Ahead Sausage and Herb Stuffing Recipe.
To rehydrate celery leaves, place them in a plastic bag and spritz them with water and then toss them until rehydrated.
Crumble Celery or Process it Into Powder Before Using
I like to process freeze-dried celery in the blender and make celery powder. I use this powder anytime I want to add extra nutrition or celery flavor.
Ways to Use Freeze-Dried Celery Powder or Crumbled Celery Leaves
- Homemade seasoning mixes. Mix together equal parts of freeze-dried herbs like thyme, oregano, parsley, etc., with freeze-dried vegetables like carrots and celery.
- Smoothies – adding some freeze-dried celery powder will give your smoothie a fantastic texture and extra nutrition!
- Adding it to soups, dips, and stews.
- Homemade celery salt. Learn how to make it here.

- Freeze-Drying – an overview | ScienceDirect Topics (www.sciencedirect.com). According to this source, compared to other drying methods, such as air drying or sun drying, freeze-drying can retain more of the food’s original flavor, texture, and nutrient content. This is because freeze-drying involves removing water from the food by sublimation (ice turns directly into vapor) without exposing it to high temperatures or oxygen, which can cause nutrient degradation. As a result, freeze-dried foods can have a longer shelf life without compromising their nutritional quality.
- Dirty Dozen™ and Clean Fifteen™ Lists | EWG’s 2021 Shopper’s Guide to Pesticides in Produce™ (www.ewg.org). According to this source, the Environmental Working Group (EWG) lists celery as number 10 on the Dirty Dozen list for 2021, which means that it was found to have a high amount of pesticide residue. The EWG recommends that consumers buy organic celery or wash it thoroughly before eating to reduce exposure to pesticides.

I heard that you can add a little baking soda to the blanching water and it helps keep the color. I did this when I freeze dried my home grown and you cannot believe the difference in the color. I had bought a #10 can from one of the suppliers, mine turned out much better. I don’t think they blanch first. Try it.
Great idea, thanks!
I just ran 2 stalks through my freeze dryer. Now, after I defrosted, the whole things smells like celery and I really need to do milk. How do I get the smell out of the dryer and/or will it transfer to the milk and cream cheese?
Good question. Wipe down the chamber and trays with a 50/50 mix of white vinegar and water to neutralize odor or wipe-down with baking soda and water, then rinse well. If the odor still persists you can leave the door open for a while or run a short empty cycle (2–3 hours) with a bowl of baking soda. Yes, odor transfer is possible, especially to foods that absorb smells easily like milk. Hope this helps.
