Key Takeaways:
- Dry herbs are an easy and cost-effective way to preserve fresh herbs while extending their shelf life for up to one year when stored correctly.
- Woody herbs such as rosemary, thyme, oregano, sage, and marjoram retain their flavor exceptionally well after drying, while delicate herbs like basil, parsley, cilantro, and mint are often better frozen instead.
- Harvest herbs early in the morning before flowering for the highest concentration of essential oils and the best flavor after drying.
- Air drying, using a food dehydrator, or drying herbs at low oven temperatures are the most reliable methods for preserving herbs without sacrificing their aroma.
- Store dried herbs in airtight glass containers away from heat, moisture, and direct sunlight to maintain freshness and potency for months.
- Because dried herbs are more concentrated than fresh herbs, use approximately one-third the amount when substituting them in recipes.
Overview
Dry herbs are fresh herbs that have been dehydrated to preserve their flavor, aroma, and nutritional compounds for long-term use. Drying herbs is one of the oldest and most effective food preservation techniques, helping reduce waste while keeping herbs available year-round. The best herbs for drying include rosemary, thyme, oregano, sage, bay leaves, and marjoram because they naturally contain lower moisture levels and retain much of their essential oils during the drying process. More delicate herbs, including basil, parsley, cilantro, and chives, tend to lose their flavor when dried and are often better preserved by freezing. There are several ways to dry herbs successfully, including air drying, using a food dehydrator, oven drying at low temperatures, or microwave drying for small batches. Proper storage is equally important. Keeping dried herbs in airtight containers away from light, humidity, and heat helps preserve their flavor for six months to one year. Whether you’re preserving herbs from your garden or reducing grocery waste, dry herbs provide concentrated flavor, convenience, and an economical pantry staple for everyday cooking.
As the weather turns cooler and the first days of fall arrive, it’s time to prepare the garden for winter. Before the growing season comes to an end, gather the remaining harvest while it’s still fresh. This is the perfect opportunity to pick ripe tomatoes for one last batch of homemade tomato sauce and harvest fresh herbs for drying and long-term storage.
One of the most traditional ways to dry herbs is by air drying. Simply gather several stems into small bundles, secure them with string or twine, and hang them upside down in a warm, dry, well-ventilated area away from direct sunlight. Depending on the humidity, the herbs usually dry within one to three weeks. For the best results, keep the drying space at a temperature of at least 50°F (10°C). This method works especially well if you have a large harvest and enough room to hang multiple bundles.
If you prefer a faster method, you can dry herbs in the oven. Set the oven to 180°F (82°C) or the lowest temperature available, as excessive heat can reduce the herbs’ flavor, aroma, and essential oils. Arrange the herbs in a single layer on a parchment-lined baking sheet, making sure they don’t overlap. Dry them for approximately 2 to 4 hours, checking periodically until the leaves become crisp and crumble easily. If your oven cannot maintain a temperature below 200°F, leave the oven door slightly open to help regulate the heat.
Another quick option is drying herbs in the microwave. While some gardeners prefer traditional drying methods, the microwave can be an effective solution when you need dried herbs in just a few minutes. Place 4 to 5 herb stems between two paper towels and microwave on high for 2 to 3 minutes. Check whether the herbs are completely dry and brittle. If they still contain moisture, continue heating in 30-second intervals until fully dried. For herbs with larger leaves, such as basil or sage, microwave 4 to 5 leaves between paper towels for about 3 minutes, adjusting the time as needed until the leaves are crisp and ready for storage.
Using a food dehydrator is one of the easiest and most reliable ways to preserve fresh herbs while maintaining their flavor and aroma. There are many excellent dehydrators on the market, but I especially like the model shown above because it consistently dries herbs, fruits, and vegetables evenly. It comes with five stackable trays and can be expanded to hold up to thirteen trays, making it perfect for everything from small herb batches to large garden harvests.
For added versatility, you can use a solid silicone tray liner to make homemade fruit roll-ups—a favorite treat for the grandkids—or a fine mesh liner for drying delicate herbs and small fruit or vegetable pieces without them falling through the trays. Another feature I appreciate is the adjustable temperature control, which allows you to choose the ideal drying temperature for different foods. According to Farmer Fred, one of its biggest advantages is its affordability, with a price of around $50. You can check it out here.
How to Dry Herbs in a Food Dehydrator
Harvest herbs later in the day after the morning dew has completely dried.
I usually don’t wash freshly picked herbs before drying. If you prefer to rinse them, gently pat them completely dry with a clean towel before placing them in the dehydrator.
Remove and discard any damaged, discolored, or unhealthy leaves.
For herbs with large leaves, such as basil or sage, remove the leaves from the stems before drying.
Herbs with many small leaves, like thyme or oregano, can be dried with the leaves still attached to the stems. Once fully dried and brittle, the leaves will easily separate from the stems with gentle pressure.
Store completely dried herbs in an airtight container. Small glass mason jars work especially well because they help preserve freshness, flavor, and aroma for months.
Now that your herbs are ready, it’s time to enjoy them! Add your homemade dried herbs to soups, stews, roasted vegetables, marinades, salad dressings, or your favorite pasta sauce for fresh garden flavor all year long.

BONUS: How To Freeze Fresh Herbs.
Fresh herbs are easy to preserve for later use. Strip the leaves from the stems, place them in a freezer-safe zip-top bag, and store the bag in the freezer. When you’re ready to cook, take out only the amount you need and return the remaining herbs to the freezer right away. Avoid letting the herbs thaw before using them, as they can become soft and clump together. Frozen herbs work best in cooked dishes, where their flavor is retained even though their texture changes. They’re an excellent addition to recipes such as marinara sauce, soups, stews, casseroles, and other simmered dishes.
