How To Dehydrate Watermelon

Print Friendly, PDF & Email

Today I am showing you how to dehydrate watermelon. It is so easy and healthy without any chemicals and preservatives. If you have a bumper crop of watermelon, or have a market close by with some great deals, this is one way to make some easy snacks to eat every day or take hiking and camping without breaking the bank.

Do you sometimes look in the refrigerator and say, “I am not going to be able to eat all that watermelon.” I updated this post today with better images and more information. I wrote the original post back in 2014 and I really wanted to share this one with you again. I love dehydrated watermelon!

Have your dehydrator handy and cut the watermelon into bite-size pieces and start drying them. If the watermelon is sweet, the dehydrated watermelon pieces will be sweet too. Remember you can dehydrate in your oven or on screens in the sun if you don’t have a regular dehydrator. My message today is directed to those who have a dehytrator. Are any of you planting watermelon seeds this year?

This particular watermelon was seedless (you can see the small white seeds). If you dehydrate a regular watermelon with black seeds you will want to remove the seeds before dehydrating. I will only dehydrate a seedless watermelon, I am not removing any seeds. LOL!

How To Dehydrate Watermelon

How To Dehydrate Watermelon

Step One

Wash the outside of the watermelon. Cut watermelon and remove the rind. I use a serrated knife to slice through the thick rind. I cut the ends off to make it easier for me to remove the rind. This is a “seedless” watermelon, but they always seem to have seeds.

Cut the Ends Off

Step Two

After I cut the ends of the watermelon off, it made the watermelon more stable for me to slice through. I started out with my Cutco bread knife and had to switch to another bread knife with a serrated edge.

Cut the rind off

Step Three

The next step is to cut the melon in half.

Cut into fourths

Step Four

Then slice the sections into 1/2-inch slices. I’m making watermelon wedges here to dehydrate.

Slice the Watermelon

Step Five

Then slice it in half again to make the watermelon slices easier to dehydrate.

Cut in half again

Step Six

Then place the wedges evenly on the dehydrating racks.

Step Seven

Of course, we all want to dehydrate watermelon into one-inch squares too because they are easy to take backpacking or for everyday snacks.

Step Eight

Place the racks in your dehydrator to start the drying. I have an Excalibur Dehydrator that states 135 degrees is the temperature for my unit when working with this kind of food product. Please check your brand to see what temperature they suggest. The time will always depend on the humidity in the room where you are dehydrating your fruit. Today this batch of watermelon took about 9 hours. No chemicals or preservatives.

Finished Product-Wedges

These took about 9 hours as well. I dried them at the same time as the cubes, just on different racks.

What is conditioning after dehydrating?

This is how I “condition” them. I know they are dehydrated but I want to make sure every single section is totally dry. Yes, they will be pliable and somewhat sticky. They are perfect. I let them sit out for at least a week to complete the conditioning stage.

Can I dehydrate watermelon in my oven?

Yes, you can. Set your oven at the lowest possible setting. Leave the door open slightly with a piece of foil wadded up into a ball. You need air to circulate around the food you are drying. You will need to watch the food closely because it is a little more tricky for the dehydrating time. Place your food on a nonstick tray.

What are the health benefits of watermelon?

Watermelon is a healthy low-calorie snack packed with antioxidants, essential nutrients, vitamins, and minerals. It’s a great fruit for hydrating your body.

How do I store the finished product?

How To Condition Your Fruit or Vegetables

If you live where it is HUMID: “To condition the fruit, take the dried fruit that has cooled and pack it loosely in plastic or glass jars. Seal the containers and let them stand for 7 to 10 days. The excess moisture in some pieces will be absorbed by the drier pieces. Shake the jars daily to separate the pieces and check the moisture condensation.”

I live in the DRY DESERT: I set my fruit and vegetables on my countertop for 5-7 days. Ten days is even better to make sure everything is dry before using your FoodSaver unit.

My favorite containers to store these in are wide-mouth quart mason jars. I remove the air with my FoodSaver® Jar Sealer. This FoodSaver® Jar Sealer is built into my unit. This one is also workable for other units, at least the hose anyway. FoodSaver® Jar Sealer The unit must have an accessory hose opening. Please note, I do not use oxygen absorbers, it’s a personal thing. I only dehydrate what I will eat within one year.

  • 1 watermelon washed, and rind removed (cut in one-inch cubes or 1/2-inch thick wedges)
  1. Place the watermelon pieces on the dehydrator racks spacing them so they do not touch each other. This way they will dry more evenly. I used an Excalibur Dehydrator and my manual says to set the temperature at 135 degrees. Be sure and look at your own dehydrator to see the correct temperature for your dehydrator. The time to dehydrate will always depend on the humidity of the room you are using to dry the product. Today this batch of watermelon took about 9 hours. No chemicals or preservatives.

Final Word

Preserving fruits and vegetables brings me so much joy. I have my dehydrator sitting out on the kitchen counter so I can load it every day if I have some excess fruit or vegetables. When you dehydrate watermelon your house smells so good. Of course, the finished product is super yummy! Please let me know what you are dehydrating this season, I’d love to hear from you. May God Bless this world, Linda

    You mentioned that you can dehydrate the watermelon in the oven, but didn’t say how. My kids love watermelon, but we don’t have a dehydrating machine, so I would love to know how to use the oven to do the dehydrating. Thanks!

      Hi Rennie, I am so glad you asked. i just added the information to my post! ***Please note if you do not have a dehydrator you can use your oven. Set your oven at the lowest possible setting. Leave the door open. You need air to circulate around the food you are drying. You will need to watch the food closely because it is a little more tricky for the dehydrating time. Place the your food on a nonstick tray. My electricity is so expensive where I live it is cheaper for me to use a dehydrator. Thanks for asking the question! Linda

      Hi Faith, they look fabulous! I was happy to ready you dehydrated them in your oven! Love it! I was already following you! Thanks Linda

    Can you dehydrate in a gas oven using only the pilot light? It seems so wasteful burning all the time for nothing.

    • March 14, 2014 at 9:13 am

      Hi Sandra, I think it is a waste of fuel myself to dehydrate food in MY oven. Our electricity is so expensive where I live. I only have an electric stove. I have always had a gas stove. I think you would want air flowing through your oven. I wonder if you just took your cookie racks that we all cool our cookies or cakes on…and let them air dry. I know a lot of people dehydrate food outside with screens. The pilot light scares me a little. Is there a smell/fume it would put in the food because it would take days to dry. Not sure??? I know dehydrating needs air to dry the food…I wish I could answer that question. Thanks for stopping by! Linda

    Do not dehydrate over 115 — you want the watermelon to still be a living food. Temps over 115 kill the food.

    • March 14, 2014 at 10:30 am

      Terry, really? I did not know that. Do you think the Excalibur Dehydrating Book shows higher temps for a reason? Linda

      • March 14, 2014 at 2:25 pm

        Linda, I’ve been raw vegan for many years, so am sensitive to the temps food is prepared at. The basic idea is that cooking destroys not only many of the vitamins in food but also enzymes that are important to our health.

        Food that reaches 115F-118F is no longer considered raw because at temperatures above that, the food’s nutrition is diminished.

        Because of this, dehydrating temperatures for food that still qualify as raw once dried are typically between 105F/41C and 115F/46C. That is significantly lower than the 135F/57C to 150F/66C usually recommended for drying fruits and vegetables. What this means is that if you want to dry foods but still keep their raw status, you’ll need to allow for up to 1/3 longer drying time than the usual dehydration recipe will specify.

        I actually have two Excalibur dehydrators … love them! 🙂

        • March 14, 2014 at 4:35 pm

          Terry, I LOVE this!!!! I will have to do posts that show the Excalibur temperature but I am thinking the true raw vegans would know this…right? Would you be interested in doing a post about this for my website? Or do you have a website I could link to? Let me know. It would have to be original content from you with your pictures so I could pin them with your watermark is great. Let me know if you would be interested. Thanks so much! Linda

    You mentioned everything accept how you store your dehydrated watermelon. I have read so many different articles, I am wondering who is correct. Some say store up to 2-4 weeks and after that its implied that it no longer good, others have said years – I could just as easily freeze the watermelon for longer storage. Does thickness affect storage? If I place the watermelon in air tight containers and store in an area that remains below 60 degrees how long should it last? Thank you in advance for any help.

    • June 3, 2018 at 2:27 pm

      Hi, William, I store my dehydrated watermelon for 2 weeks at the most. Thickness effects how long it will take to dehydrate. I have frozen watermelon for smoothies. I received my Master Canning & Preserving Certificate and what you may read on the internet please be cautious with the information. Please check your USDA canning and preserving guidelines. They change often. Please be safe, when in doubt throw it out. Linda

    I’ve got some to freeze dry. Just haven’t got to it yet

    • October 20, 2021 at 8:48 am

      Hi Matt, oh my gosh, let me know how it turns out! AWESOME! Linda

  • October 20, 2021 at 8:44 am

    Good article Linda. I have an Excalibur myself. Love it and so easy to clean. I read some where that dehydrating foods only last a year. Some of mine I had to toss that were over a year old. Anyone else had this problem? I keep mine in mason jars also and make sure they are very dry before addding to jars.

    • October 20, 2021 at 8:52 am

      Hi Judy, that is true, they are only good for a year. When I took my Master Canning and Preserving class they mentioned both home-canned, pressure-canned, and home dehydrated food is good for a year. Yes, I have eaten canned peaches that were probably 3 years old, but the idea behind preserving our own food is to plant the seeds, grow the food, then harvest it, and preserve it for a year. Then start the cycle again. I love dehydrating food! Linda

      • October 20, 2021 at 9:21 am

        I have to disagree about pressure canned food being good for only one year. I keep my pressure canned foods in a cold dark place and have eaten foods several years old. I always check for unsealed jars, odor and looking at the food for spoilage. I have never had any problems and as usual always boil food 10 mins. before eating.

        • October 20, 2021 at 7:11 pm

          Hi Judy, I’m just telling you what I learned from my class. I have eaten food that is older than a year. Linda

          • October 21, 2021 at 6:07 am

            Yes I understand. I was talking about what they taught you. It is good to have good discussions.

    Step 9 : use the rind to make watermelon pickle!

    • July 15, 2022 at 8:00 am

      Hi Diana, oh my gosh, I forgot about watermelon rind pickles!! I haven’t made those in years! They are so good!! Linda
