These easy oven dried lemon slices are ready to brighten up your cocktails, teas, or desserts without using any fancy dehydrator. Dehydrated lemon slices is one of my favorite ways to garnish zesty drinks or baked goods - crisp, tangy, and absolutely gorgeous.

If you're into oven dried fruit, try my Dried Apple Slices - perfectly chewy and naturally sweet. I love keeping these aesthetically pleasing dried fruits in glass jars on my kitchen counter for vibrance.

Why You’ll Love Oven-Dried Lemons

• No dehydrator needed -  just your oven.
• Naturally vegan and preservative-free.
• Shelf-stable for months in an air-tight jar.
• Incredibly versatile - use to garnish cocktails or teas, infuse soups or stews, or use it to make a holiday dried citrus garland.

What Are Dried Lemon Slices?

Dried lemon slices (also called dehydrated lemon slices, lemon wheels, or dried lemons) are thin circular pieces of lemon that are dried until crisp or chewy. They are most commonly used to garnish beverages, or desserts (little citrus rounds on lemon cupcakes are my fav!). Not only are they a stunning pantry staple, but they also hold a good amount of health benefits as the dehydration process concentrates the nutrients found in fresh lemons - like vitamin C, fiber, and antioxidants.

Ingredient Notes

• Fresh lemons: I recommend Meyer or Eureka lemons for best results. But homegrown lemons will be fine as long as they are unwaxed.
• Optional: Sprinkle over sugar, cinnamon, or cardamom for spiced citrus wheels.

Using non-organic vs organic lemons? Go organic when you can. Non-organic lemons are waxed, and while scrubbing helps, unwaxed lemons dry more evenly and keep better color retention in dried lemon slices.

How to Make Dried Lemon Slices in the Oven

Slow baking thinly sliced lemons is the key to dry lemon slices, removing all the moisture. This process concentrates the flavor without actually cooking, enhancing the natural tanginess and imparting a slightly chewy texture.

Step 1: Slice the Lemons

Wash, dry, and slice lemons into ¼ inch slices (6 mm) using a sharp knife or a mandoline for even slices. Remember, uniform thickness is key for even drying. Thin slices dry crisp, thicker ones stay leathery. Same prep applies if you want dried orange slices, dried lime slices, or even dried grapefruit slices.

Step 2: Arrange for Drying

Line a baking sheet with parchment or set a cooling rack on top (I prefer using the cooling rack). Lay slices in a single layer, no overlaps. This setup works for all dehydrated citrus - lemon, lime, orange, or tangerine slices.

Step 3: Bake Low & Slow

Bake at 200°F for 2 hours, then flip all slices and rotate the baking sheet once and bake for another 1 hour.

Step 4: Cool & Store

Cool completely (they crisp as they cool), I suggest leaving them out on the cooling rack for 6-8 hours to remove all moisture after drying - letting slices air out before sealing helps prevent mold. Store your dehydrated lemons in an air-tight jar. I love using wide-mouth glass jars - they show off the color and double as kitchen décor.

Pro Tips for Perfect Dried Citrus

• How to know when they’re done: Slices should look translucent and feel dry, not sticky. Thin = crisp, thick = leathery.
• Remove seeds before drying (optional): Some feel that the seeds burn easily and make the lemon rind bitterness more noticeable after drying (I don't mind having some dried citrus slices with seeds intact for aesthetics purposes).
• For better color retention in dried lemon slices, use fresh, unwaxed lemons and dry low and slow.
• Crack the oven door slightly if edges brown - handy when drying oranges in the oven too.
• In humid climates, store dried citrus for cocktails in the fridge or freezer.

Why Oven Dry Over Other Methods?

Oven dried citrus - whether it’s lemons, oranges, or limes - works every time without fancy equipment because it's reliable and simple. Air drying often fails in humid places, and while a dehydrator is great, not everyone has one. With the oven, you control the process - and your whole kitchen smells like citrus candy.

Wondering how to dry lemon slices in a humid climate? Slice thinner (⅛ inch slices, 3 mm). Keep your oven on the lower end (170°F) and extend drying time (3-4 hours) - then let slices cool completely before storing in the fridge or freezer.

Common Mistakes (and Fixes)

• Slices too thick? They’ll stay damp. Slice thinner for proper lemon dehydration.
• Tray overcrowded? They steam instead of dry. Spread citrus slices apart.
• Brown edges? Oven temp too high. Same issue when baking oranges.
• Mold later? Not fully dry or stored incorrectly. Learn how to store dried citrus long term: airtight jars, cool spots, or the fridge in humid areas.
• Seeds left in? Adds lemon rind bitterness after drying. Remove them if infusing for flavor. Keep them intact for decorating desserts.

Flavor Variations: Beyond Lemons

Dried citrus isn’t just lemons. Try other drying other citrus fruits:

• Dried orange slices: Sweet and festive, perfect for holiday mocktails.
• Dried lime slices: Sharp and tangy, beautiful on margaritas.
• Dried grapefruit slices: Bittersweet and bold, a classic garnish for Gin & Tonic.
• Dried blood orange slices: Ruby-red and striking, well-suited for drinks with a deep color profile.

Mix them together for colorful dried citrus slices - perfect for a dried fruit cocktail garnish or holiday decorations.

Best Lemons for Drying

Meyer = sweeter and golden. Eureka = tart and pale. Both make great dried lemon slices for cocktails or baking. Always choose fresh, unwaxed fruit for the best results.

Storage & Shelf Life

Keep dried lemon slices in airtight jars for 6-12 months. In humid climates, refrigeration is best. “Condition” by shaking the jar daily for the first week. If slices clump, re-dry for 20 minutes.

How to store dried citrus long term? Keep airtight, in a cool, dark place. For very humid areas, vacuum sealing or freezing keeps slices safe.

Ways to Use Dried Citrus

There are so many ways you can incorporate dried lemon slices into your cooking! Here are some of my favorites:

• Add dried lemon wheels to tea, sparkling water, or kombucha.
• Use dried lemon slices for cocktails - or swap in dried fruit slices for cocktails like sangria or margaritas.
• Garnish drinks with these gorgeous citrus rounds - serve them with some of my favorites Brazilian lemonade, ginger beer mocktail, coconut water mocktail, or cranberry mocktail.
• Decorate cakes or pastries with a lemon slice for a decorative touch. You can try adding some to my vegan olive oil cake!
• Crush the slices and add them to stews and soups like my chickpea soup. They work well in Mediterranean, Middle Eastern, and North African dishes.
• Grind into dried lemon powder recipe for spice blends, rubs, or citrus sugar.
• Make chocolate-coated lemon slices by dipping them in melted dark chocolate. Let them dry on a parchment paper-lined pan.
• They also double as beautiful decorations - think holiday centerpieces or citrus strands. Here’s a great dehydrated citrus garland DIY if you’d like to try it.
