How to Dehydrate Lemons (3 Easy Methods)

1. Using a Dehydrator

This is the most efficient and consistent method.

What You’ll Need:

• Fresh lemons

• Sharp knife or mandoline

• Food dehydrator

Steps:

1. Wash lemons thoroughly.

2. Slice lemons into even 1/8- to 1/4-inch thick rounds.

3. Arrange slices in a single layer on dehydrator trays.

4. Set temperature to 135°F (57°C).

5. Dry for 6–10 hours, checking at the 6-hour mark. Slices should be dry and slightly brittle.

2. Using an Oven

Perfect if you don’t own a dehydrator.

Steps:

1. Preheat oven to 170°F (or the lowest setting).

2. Line a baking sheet with parchment paper.

3. Place lemon slices in a single layer.

4. Bake for 2–3 hours, flipping halfway through.

5. Let cool completely before storing.

Tip: Prop the oven door open slightly to allow moisture to escape.

3. Sun-Drying (Natural Method)

Best for warm, dry climates.

Steps:

1. Place slices on a mesh rack or screen.

2. Set them in a sunny spot with good airflow.

3. Cover with a thin mesh or cheesecloth to protect from bugs.

4. Bring inside overnight.

5. Dry for 3–5 days, depending on weather conditions.

Storage Tips

To keep dried lemons fresh:

• Store in airtight jars or containers

• Keep in a cool, dry, dark place

• Use within 12–24 months

To test if they’re fully dried, press a paper towel against a slice. If any moisture transfers, they need more time.
