Wash approximately 6 lemons to remove dirt or wax. If using non-organic lemons, scrub with a vegetable brush to remove pesticides. Using a mandoline or a very sharp knife, slice lemons into uniform ⅛" slices.
If lemons have seeds, remove the seeds before dehydrating them. Arrange lemon slices on dehydrator trays in a single layer. Do not overlap, leave room for air circulation.
Add the dehydrator cover and set the temperature to the fruits & vegetables setting (135°F). Set a timer, and flip the lemon slices after a few hours to prevent them from sticking to the trays. Dehydrating lemons can take up to 6+ hours. Lemon slices are done when they are crisp and no longer sticky, tacky, or pliable.
How to Store Dehyrdated Lemons
Allow the dehydrated lemons to cool completely to prevent condensation, then store them in a quart-sized mason jar. Use a mason jar vacuum sealer to remove excess air from the jar. This will keep the dehydrated lemons fresh longer. Store the jar in a cool, dark location, like a pantry.
Notes
Slice lemons into uniform, thin slices (about ⅛ thick) for consistent drying. The thicker they are, the longer they will take to dry.
If you have lemon pieces that are too thick or too thin, don't toss them out. You can still dehydrate them, then add them to your water or tea for a lemony flavor. You can also grind these pieces into powder!
Before dehydrating, gently remove the seeds to avoid bitterness.
Sprinkle with sugar or spices (e.g., cinnamon) before drying for added flavor.
Store in an airtight jar or container in a cool, dark place, such as a pantry.
Occasionally check the container to ensure no moisture has developed, which could lead to mold. Adding an oxygen absorber can be helpful!
