These dried lemon slices are an easy way to turn fresh lemons into a bright, beautiful garnish for drinks, desserts, and more. All you need is your oven (no dehydrator required!) and a little patience for perfectly dried lemons every time!

If you enjoy preserving fruit at home, try my Oven-Dried Apple Slices without a Dehydrator next.

I love keeping a jar of these dried lemon slices on hand because they instantly make simple drinks and desserts look a little extra fancy! I use them to dress up drinks like my Refreshing Coconut Water Mocktail, pair them with my 3-Ingredient Lemon Simple Syrup, or use them to decorate my Vegan Lemon Olive Oil Cake for a pretty citrusy finish.

Ingredient Notes

Fresh lemons: I recommend Meyer or Eureka lemons for the best results. Choose firm, fresh lemons with smooth, unblemished peels. Lemons with less white pith tend to taste less bitter once dried. You can remove visible seeds after slicing for a cleaner-looking garnish, but it’s not necessary.

Using organic vs. non-organic lemons? Organic lemons are a great choice when you can find them, especially since the peel stays on. Whether you use organic or conventional lemons, wash and scrub them well before slicing to remove any dirt or surface coating.

How to Make Dried Lemon Slices in the Oven

Step 1: Wash and dry the lemons, then cut them into even ¼-inch (6 mm) slices using a sharp knife or mandoline. Keeping the slices uniform helps them dry at the same rate.

Step 2: Place a cooling rack over a baking sheet and arrange the lemon slices in a single layer without overlapping. I prefer a cooling rack because air can circulate around both sides of the slices for more even drying.

Step 3: Dry at 200°F for 2 hours. Flip the slices, rotate the baking sheet, and continue drying for about 1 more hour. Start checking during the final hour and remove individual slices as they finish, since thinner or smaller slices may dry faster.

Step 4: Transfer the dried lemon slices to a cooling rack and let them cool completely. I like to leave mine uncovered for 6–8 hours before transferring them to a jar for conditioning.

How to Tell When Dried Lemon Slices Are Done

Dried lemon slices are done when they feel dry to the touch with no soft, sticky, or moist spots in the center. Let a slice cool before checking, since it will firm up and become slightly crisper as it cools.

• Check the center: It should feel dry rather than tacky or moist.
• Look at the edges: They may curl slightly and deepen in color as the slices dry.
• Test the texture: Thinner slices will be crisper, while thicker slices may remain slightly flexible even when fully dried.

Pro Tip: If some slices finish before the others, remove them individually and return the rest to the oven. Lemon size, slice thickness, humidity, and oven temperature can all affect the total drying time.

Common Mistakes (and Fixes)

• Dried lemon slices are turning brown: The oven may be too hot or the slices may have dried too long. Lower the temperature and remove finished slices early to help preserve their bright color.
• Slices are dry around the edges but moist in the center: They may need more time in the oven. Continue drying at a low temperature until no sticky or moist spots remain.
• Moisture appears after storing: The slices may not have been completely dry before sealing. If you notice condensation but no spoilage, dry them again before storing. Discard any slices that show mold.

How to Dry Lemon Slices in Humid Weather

Humidity can make lemon slices take longer to dry because moisture evaporates more slowly. Keep the oven between 170°F and 200°F and allow extra drying time as needed, using the doneness cues above rather than relying only on the clock.

Pro Tip: If the slices still feel tacky after cooling, return them to the oven until fully dry.

Dried Citrus Variations

You can use the same low-and-slow oven method to make other dried citrus slices, including oranges, limes, grapefruit, and blood oranges. Drying time may vary depending on the fruit's size, moisture content, and slice thickness.

• Dried orange slices: Sweet and festive for holiday drinks, desserts, or as a garnish for a Cranberry Orange Mocktail.
• Dried lime slices: Bright and tangy, perfect for garnishing sparkling water, tea, and other refreshing drinks.
• Dried grapefruit slices: Bittersweet and colorful for mocktails, sparkling drinks, or dessert garnishes.
• Dried blood orange slices: Deeply colored and especially pretty for holiday drinks, dessert boards, and seasonal decorating.

You can also pair the different citrus varieties with flavored syrups, like my Homemade Orange Simple Syrup.

Pro Tip: Larger or juicier citrus slices may need more time in the oven, so use the same doneness test rather than relying on the clock.
