How to Dehydrate Lemons
Quick-drying FAQ: Dry at 125°F/52°C for 18-36+ hours until dehydrated lemon slices snap when cooled and there is no moisture in any of the cells.
Step one
Wash lemons thoroughly. Even if using organic, you should soak and wash the orange to remove any residue and wax that may be on the skin.
Soak in a 50/50 solution of water and vinegar for about 15 minutes. Scrub with baking soda if you feel it necessary.
Step Two
Slice lemons into ¼" slices (6-7 mm). Using a good serrated bread knife works wonders for cutting lemons by hand, and is my favorite way to cut lemons. You can also use a meat slicer.
Tip: If using a mandoline or meat slicer, cut the end of the orange to give yourself a flat surface.
Tip 2: PLEASE remember to wear a protective cutting glove when using a mandoline. Even if you can use the guard that comes with the machine, hands and surfaces become slick.
Step Three:
Place slices on trays. You can pack them fairly close together without overlapping. Some airflow is nice, but they don't need a ton of space, nor will they shrink much.
Dry at 125°F/52°C or lower for 18-36+ hours.
While the recommended temperature for fruit is 135°F/57°C, lemons often brown during drying as the sugars brown from the heat. Dropping the temperature can help prevent that, though you do have to add a little more time to the drying process.
You can use a liner such as silicone mesh or parchment paper, but it's unnecessary.
Tip: Flip your slices after the three to four-hour mark, and every five hours to keep them from sticking to your trays.
Step Four:
Test. Allow a sample or two to come to room temperature. It is fully dry when you can snap it in two easily, and there is no moisture in the cells of the flesh.
Step Five:
Don't miss this vital step! Conditioning allows you to catch any areas of moisture before they turn into mold.
- Simply shake the jar once a day for five days to watch for signs of sticking, moisture buildup, or mold.
- If you see sticking or moisture, put the potatoes back into the dehydrator to dry more. If you see mold, toss.
Step Six:
Store in an airtight container for up to eighteen months, though you'll likely get a much longer time with proper storage techniques.
Oven Directions:
- Slice citrus into ¼" slices.
- Place parchment paper onto a metal cooling rack.
- Place lemon slices in a single layer.
- Turn the oven to the lowest temperature, preferably 170°F/60°C or below.
- Use a wooden spoon or another oven-safe silicone mitten to crack the door if it's too hot.
- Flip citrus after 2 hours.
- Dry until completely dry, approximately 4-6 hours.
- Store as above.
How to Use Dried Lemon Slices
Your dehydrated slices will look so pretty in your containers, but they have many more uses than simply throwing them in a potpourri bowl.
- Roast chicken: Place slices in the cavity or make a bed for the chicken to sit on.
- Dry lemon slices can be used on fish or other seafood, or as a base to lay on during the baking process.
- Mix with pepper, grind, and make lemon pepper seasoning
- Slip your dried lemon wheel into a glass of water or tea to bring a bright orange flavor.
- Add a citrus weel onto the rim of your glass as a garnish on cocktails
- Create a citrus garland with lemon, orange, and lime slices. Remember to spray with a protective coating if displaying any citrus on a wreath or other decoration for any period of time to seal it.
- Simmer in a pot with cinnamon sticks, cardamon, and allspice for an autumn/winter ambiance

How to Dehydrate Lemon Zest
If you want the zest from any citrus variety, you can do it on its own, and still dehydrate the leftover citrus slices. The dried lemon peel can store easily for about a year.
- Use your favorite lemon zester to remove the zest (minus the white pith), lay between two paper towels, and allow to air dry for a day or so.
- You can also place them in a coffee filter or onto dehydrator trays on your dehydrating trays and dry at 95°F/35°C until dry.
- Peel the lemon like an apple, and place the zest slices onto dehydrator trays to dry at 95°F/35°C until crisp (approximately 8 hours).
Store in an airtight container and use in place of fresh zest if you're out, by grinding in a coffee grinder or finely chopping into small bits.

How to Make Lemon Powder
Dry fruit thoroughly with the instructions above. Your lemon slices must be completely dehydrated before powdering.
- Break slices up into the grinder of your choice. I often use a NutriNinja bullet blender, but a coffee grinder or large blender work well, too.
- Pulse your grinder four or five times before commencing to a sustained grind. Please follow the instructions for your particular grinder.
- Condition: Place powder on parchment paper on a cookie sheet in a warmed (but off) oven OR back into your dehydrator in coffee filters, muffin papers, etc. to dry for 15-30 minutes.
- Allow to come to room temperature, then store in an airtight container, preferably with a moisture absorber. Follow these tips to help prevent clumping in orange powder.

Commonly asked questions
Typically, most dehydrated foods are best within a twelve to eighteen-month window that you dry them. However, with proper airtight storage techniques, you're likely to get much longer time from them.
While lemon peels are edible, you need to weigh the organic vs. conventional citrus debate about clean fruit.
Lemonade is made from the juice and pulp of oranges. With dehydrated slices, you can flavor water with the essence of lemon. Place lemon slices in a jug of water to allow to soak for a day or so, add simple syrup and have something similar to lemonade.
Time is relative when dehydrating. It depends on your machine, your home's humidity, the moisture in your fruit, how thick you've cut the slices, etc. Use the time mentioned as a window of time, not an exact one. Keep drying if they aren't fully dried, yet!
Yes, in two cases. Using too high heat in your dehydrator or oven can cause the sugars to brown. They aren't necessarily burned, but turning down the temperature can really help. The other issue is storage. Lemons and other citrus stored where direct sunlight can get to them will degrade and turn brown over time. Airtight containment in a dark, cool, dry place is best.
Air drying lemon zest is the easiest way, but you can also use a dehydrator to dry them (95°F/35°C) or freeze them in portion-sized mounds. They last for a year or so dried.

Hi Darcy
I followed your way of dehydrating lemons worked great but a week later the lemons are now sticky What did I do wrong or do I start again or are they still good?
Darcy Baldwin says
You didn't do anything wrong - but here are my thoughts: They weren't really dry enough. They were stored in a jar with way too much air. If you opened and shut them a lot and there was a lot humidity - you were introducing humidity every time. Just throw them back in, dry them more, and maybe use a moisture absorber with them once you store them.
Janis Patton says
Thank you I will do that by the way, I love your youtube channel
Louise says
Is this the same process if they are candied.
I have some left over from making a lemon syrup and I was going to put them in the dehydrator. Not sure if they will just end up burning because of the sugar or not.
Darcy Baldwin says
Yes, but drying time will be different because of the added sugars.
Amber L Caruso says
Do you use white vinegar or apple cider vinegar?
Thanks
Amber
Darcy Baldwin says
Regular vinegar.
