Dried citrus is one of the easiest ways to elevate cocktails at home, and you don’t need a dehydrator — this simple oven method works beautifully.

The other day I was at my fancy local green grocer and spotted little pouches of dehydrated citrus — so pretty, so cheerful, and absolutely perfect for cocktails. But at $20 a bag, I just couldn’t justify it. I love having citrus garnishes on hand for spritzes and G&Ts over summer, especially at Christmas, but not at that price. So I decided to make my own.

I don’t own a food dehydrator (and honestly, I don’t have space for another kitchen gadget), so I wanted to figure out how to make dried citrus slices using nothing more than my oven. No wire racks, no special equipment — just thinly sliced fruit, low heat and a little patience.

And the result? Gorgeous stained-glass slices of oranges, lemons, limes and blood oranges, perfect for cocktails, grazing boards or packaging into sweet little jars for gifting. You can even string them up for old-fashioned Christmas decorations — they look beautiful hanging in a sunny window.

My son is also obsessed with Bonne Maman raspberry jam, so I always have a collection of their jars tucked away in the cupboard. The red-and-white lids feel instantly festive and make the cutest little Christmas gifts filled with mixed citrus slices and tied with a bow. It’s simple, sustainable and genuinely joyful — my favourite kind of project at this time of year.

Ingredients Explained

Oranges – sweet, aromatic, classic in cocktails.
Lemons – bright and slightly tart; great for gin.
Limes – fresh and zesty; they dry quickly.
Blood oranges – deep colour and especially beautiful for gifting (I couldn’t get them because they are out of season but if you can you should).

You can keep them plain or lightly dust them with vanilla sugar or cinnamon for gifting, though I prefer them neutral for cocktails.

Pro Tips

• Slice evenly so everything dries at the same rate.
• If edges start browning, lower the temperature slightly.
• Make sure slices are fully cool before sealing jars.
• Mixed citrus jars make the prettiest gifts.
• Blood oranges can take slightly longer to dry due to moisture content.

---

Substitutions

• Grapefruit — dries beautifully and adds gentle bitterness.
• Vanilla sugar — lovely for scented gifting.
• Cinnamon or mixed spice — festive but better for decorations than cocktails.

Storage

Store in airtight jars for up to 6 months, away from direct sunlight to preserve colour.

FAQs

Do I need a wire rack?
No — lined trays work perfectly.

Why are some slices still soft?
They may be thicker or juicier. Return them to the oven for another 20–30 minutes or allow them to finish drying in the cooling oven.

What drinks do they work best in?
Spritzes, margaritas, gin and tonics, iced water or festive punch bowls.

How thin should I slice them?
Around 3 mm — thin enough to dry evenly while still holding their shape.

If you enjoy making simple summer drinks at home, these dried citrus slices are lovely to keep in the pantry. I use them all the time in my Aperol Spritz, they make a great little garnish for a Classic Margarita, and they’re perfect dropped into a really cold G&T.
