Picture this: It’s a chilly January evening, snow falling outside your window, and you’re curled up with a steaming mug of peppermint tea made from mint you harvested back in June. The aroma alone transports you back to those warm summer days in your garden.
That’s the magic of drying mint—capturing peak-season freshness to enjoy all year long.
If your mint plant is taking over your garden (as mint tends to do), or you simply want to preserve that incredible burst of flavor, you’re in the right place.
Drying mint is surprisingly simple, requires minimal equipment, and yields results far superior to store-bought dried herbs.
Why Dry Your Own Mint?
Store-bought dried mint often sits on shelves for months, gradually losing its potency. When you dry your own, you control the freshness from garden to jar, and the flavor difference is remarkable.
A single mint plant can yield several jars of dried leaves throughout the growing season—that’s dozens of cups of tea and countless recipes without spending another dime.
Beyond the superior taste and savings, you know exactly what’s in your dried mint. No mystery additives, no pesticides you didn’t approve, just pure herb.
And since mint grows enthusiastically (nearly impossible to kill), regular harvesting actually helps control its spread while giving you an endless supply to preserve.
Choosing Your Mint Variety
While all mint varieties dry beautifully using the same methods, knowing what you’re growing helps you use it best.
- Peppermint packs a strong menthol punch, perfect for tea and medicinal uses.
- Spearmint offers a sweeter, milder flavor ideal for cooking—think tabbouleh and mojitos.
- Chocolate mint genuinely tastes like after-dinner mints (delightful in desserts), while apple, orange, or strawberry mints add unique twists to beverages.
The drying process doesn’t change between varieties, so feel free to experiment with whatever grows in your garden.
Timing Your Harvest for Maximum Flavor
The secret to intensely flavored dried mint starts before you pick up your scissors.
Harvest just before flowering, typically in late spring to early summer, when leaves contain the highest concentration of essential oils—those aromatic compounds responsible for mint’s distinctive taste and smell.
Head to your garden mid-morning, after dew evaporates but before afternoon heat causes oils to dissipate.
Using sharp scissors or garden shears, cut stems about one-third down from the top, leaving at least two sets of leaves near the base so your plant regenerates.
This technique encourages bushier regrowth and gives you tender leaves perfect for drying.
Avoid randomly plucking individual leaves, which weakens the plant over time. Take entire stem cuttings instead—your mint will thank you with healthier, fuller growth.

Preparing Your Mint: The Critical First Step
Proper preparation makes the difference between beautifully green, aromatic dried mint and disappointing brown leaves that taste like paper.
Fill a large bowl with cool water and swish your mint stems around to remove dirt, dust, and any tiny garden visitors. Change the water and repeat until it runs clear.
Then comes the crucial part: drying completely. Any moisture left on leaves can trigger mold during drying or spoilage in storage.
Use a salad spinner to remove excess water quickly, or lay stems on clean towels and gently pat dry.
Then let mint air-dry on towels for 1-2 hours. The leaves should feel completely dry to the touch before you proceed.
For most drying methods, remove leaves from stems by pinching the stem tip and sliding your fingers down to strip leaves in one motion.
This speeds drying and creates more even results. For air drying bundles, however, keep leaves on stems—it’s easier to handle.
Planning your harvest: Fresh mint reduces dramatically when dried—expect about 1 cup of dried leaves from 4 cups of fresh.
A bunch of mint that fills a grocery bag will fit into a single pint jar once dried. Keep this in mind when choosing storage containers.
Choosing Your Drying Method
Each method offers different advantages.
- Air drying is gentlest and preserves the most flavor but takes longest.
- Oven drying is fastest but requires constant attention.
- Dehydrators offer the best balance of speed and quality if you dry herbs regularly.
Here’s how each works:
Air Drying: The Traditional Approach
Air drying preserves mint’s vibrant color and robust flavor beautifully, and there’s something deeply satisfying about bundles of herbs hanging in your kitchen.
Gather 5-6 mint stems and secure them at the bottom with kitchen twine, tying tightly since stems shrink as they dry.
Hang bundles upside down in a warm, dry, well-ventilated spot away from direct sunlight—a spare bedroom, pantry, or shaded kitchen corner works perfectly.
For extra dust protection and to catch falling leaves, loosely slip a paper bag (with holes punched for air circulation) over each bundle.
Expect 1-2 weeks depending on humidity and bundle size. The leaves are ready when they feel crispy and crumble easily while still retaining their green color.
Small-space option: Spread individual leaves on a clean dish towel or cooling rack in a dry area, turning every few days for even drying.
Oven Drying: When You’re Short on Time
Oven drying delivers results in hours but demands vigilance to prevent scorching.
Preheat your oven to the absolute lowest setting, ideally 140-170°F. If your oven doesn’t go that low, use the “warm” setting.
Spread mint leaves in a single layer on a parchment-lined baking sheet without overlapping—each leaf needs direct warm air exposure.
Here’s the critical part: prop the oven door open slightly with a wooden spoon to let moisture escape and prevent temperature spikes.
Check after 1 hour, then every 15-20 minutes. Total time runs 1.5-4 hours. Leaves are done when they curl at the edges and shatter when pressed while still retaining green color.
Watch closely toward the end—the line between perfectly dried and burnt happens quickly.
Food Dehydrator: Consistent and Reliable
Food dehydrators offer precise temperature control and consistent airflow—ideal conditions for preserving mint’s essential oils.
Spread leaves in a single layer on dehydrator trays, leaving space for air circulation. Set temperature to 95-105°F.
Most mint dries in 2-5 hours, though humidity and leaf thickness affect timing. Leaves are ready when brittle and breaking cleanly without bending.
The advantage: you can stack multiple trays to dry large quantities at once, perfect when your mint plant goes into overdrive mid-summer.

Microwave: Emergency Option Only
This is my least favorite method because it’s easy to burn mint and lose precious flavor, but if you need dried mint immediately and have no other options, it works in a pinch.
Spread a handful of leaves on a microwave-safe plate lined with a paper towel. Microwave on lowest power in 10-second bursts, checking after each interval.
Total time usually runs 1-2 minutes, but watch constantly. Leaves should be crispy but still green—any brown spots mean you’ve overdone it.
Common Pitfalls to Avoid
Learn from these frequent mistakes:
- Drying in direct sunlight bleaches mint and destroys delicate essential oils. Always choose shade or indirect light, regardless of method.
- Using too much heat cooks your mint instead of drying it, leaving brown, flavorless leaves. Low and slow wins this race.
- Storing warm mint creates condensation inside jars, leading to mold. Always let dried leaves cool completely—give them at least 30 minutes after removing from heat.
- Insufficient drying is the biggest spoiler of stored herbs. Even slightly damp leaves will mold your entire batch.
- Overcrowding slows drying and creates uneven results. Whether in the dehydrator, oven, or on racks, mint needs air circulation space.
Testing for Perfect Dryness
Don’t skip this step—storing incompletely dried mint invites mold and ruins your hard work.
- Take a leaf and crush it between your fingers. It should shatter into small pieces, not bend or tear, with a texture like dry fall leaves.
- Grab a handful and scrunch—fully dried mint makes a satisfying crackling sound.
- While color varies slightly by drying method, leaves should remain relatively green, not brown or black.
If your mint doesn’t pass all three tests, give it more time.
Storing Your Harvest
Glass jars with tight-fitting lids are ideal—mason jars, old spice jars, or repurposed glass containers all work. Avoid porous materials like cardboard or thin plastic, which absorb aromatic oils.
Store leaves whole and crush them only when ready to use. This preserves flavor and aroma far longer—whole leaves can maintain quality for up to a year, though flavor peaks within six months. Crushed mint deteriorates within a few months.
Tuck jars in a cool, dark, dry spot away from the stove. Light and heat are dried herbs’ enemies. Label everything with the date and mint variety.

- Important first-week check:
Inspect your jars daily for the first few days. If you spot any condensation, your mint wasn’t quite dry enough—simply remove and re-dry it before mold develops.
- How to crush dried mint:
When you’re ready to use it, crumble leaves by rubbing between your palms over a bowl, or pulse briefly in a clean coffee grinder dedicated to spices. For tea, you can use whole leaves and let them steep as-is.
- Stem usage:
Don’t discard those stems! They contain oils too. Dry them separately (they take longer) and break into pieces for adding to tea or making mint-infused simple syrup.

Knowing When Dried Mint Has Gone Bad
Properly dried and stored mint lasts up to a year, but it won’t last forever. Your nose is your best guide—fresh dried mint should smell distinctly minty when you open the jar.
If it smells musty, stale, or like nothing at all, it’s past its prime.
Visually, watch for any darkening beyond the natural drying color, white fuzzy spots (mold), or any moisture inside the container. When in doubt, throw it out.
Creative Ways to Use Your Dried Mint
- Classic mint tea needs just 1 tablespoon of dried mint steeped in hot water for 3-5 minutes. Add honey and lemon for extra comfort on cold days.
- Herb blends become more interesting with mint—try mixing with chamomile for bedtime tea or adding to green tea for a refreshing morning boost.
- Cooking applications are endless. Dried mint elevates Middle Eastern dishes like tabbouleh, adds depth to lamb marinades, brings freshness to tzatziki, and perks up pea dishes (seriously, try adding a pinch to your next batch of cooked peas).
- Mint sugar starts with pulsing dried mint with granulated sugar in a food processor. Use it to rim cocktail glasses or add an unexpected twist to cookies and brownies.
- Beyond the kitchen: Add crushed dried mint to bath salts, sugar scrubs, or facial steam blends. Fill small cloth sachets to freshen drawers and closets naturally.
Quick Troubleshooting Guide
- Mint turned brown during drying: Too much heat or direct sunlight. It won’t hurt you but lacks flavor. Start fresh with lower temperatures and shade.
- Musty smell after drying: Mint wasn’t completely dry before storage or was stored in too-humid conditions. Prevent this by ensuring crispness before jarring.
- Some leaves dried while others didn’t: Leaves weren’t spread in a single layer or varied too much in size. Dry similar-sized leaves together with adequate spacing.
- Leaves are brittle but tasteless: Likely dried too long or stored in light. Use within 6 months for best flavor.
Frequently Asked Questions
- Q: Can I dry mint that’s already flowering?
A: Yes, but the flavor won’t be as intense since the plant directs energy to flowers rather than producing leaf oils. For best results, harvest before flowering begins.
- Q: How much dried mint equals fresh mint in recipes?
A: Dried herbs are more concentrated—use about one-third the amount. If a recipe calls for 3 tablespoons fresh mint, use 1 tablespoon dried.
- Q: Does climate affect drying time?
A: Absolutely. Humid climates extend air-drying time significantly (sometimes making it impractical), while dry climates speed the process. In high humidity, oven or dehydrator methods work more reliably.
- Q: Can I freeze mint instead of drying it?
A: Yes! Freezing preserves fresh mint’s bright flavor well. Try chopping leaves and freezing in ice cube trays with water or oil. But for tea and long-term pantry storage, drying is superior.
Final Thoughts
Drying mint connects you to centuries of herbal tradition while providing a practical way to preserve your harvest.
The method you choose matters less than the care you put into harvesting at peak flavor, drying thoroughly, and storing properly.
Start with whatever feels most accessible—air drying if you have space and patience, a dehydrator if you preserve herbs regularly, or even the oven in a pinch.
Your mint plant is already doing the hard work of growing; all you need to do is capture that fresh, vibrant flavor and tuck it away for those moments when you need a little garden magic in the middle of winter.
Now grab those scissors and head to your garden—those mint leaves won’t dry themselves!
