You may find yourself wondering – how long does fresh thyme last before it goes bad? With proper storage methods, fresh thyme can retain optimum flavor and quality for up to 1-2 weeks. Learning the best ways to store fresh thyme can help you enjoy it’s taste and aroma for as long as possible.
In this complete guide, you will learn:

- Tips for Using Fresh Thyme
Armed with this information, you can master keeping fresh thyme on hand to enliven your home cooking all season long. Let’s start with understanding just how long fresh thyme will last.
Shelf Life of Fresh Thyme
The shelf life of fresh thyme depends on how it is stored:
- Countertop – 1-3 days
- Refrigerator – 1-2 weeks
- Frozen – 4-6 months
- Dried – 1 year
Fresh thyme you buy at the grocery store or harvest from your garden usually comes bundled in sprigs on the stems. The leaves are most flavorful and aromatic when fresh.
At room temperature, fresh thyme will only remain usable for 1-3 days before flavor diminishes. To enjoy the herb for longer, you must employ additional storage methods.
Refrigeration can extend the shelf life of fresh thyme to 1-2 weeks. Freezing keeps thyme viable for 4-6 months, while drying allows thyme to last approximately 1 year before losing potency.
Next, let’s look at the best techniques for storing fresh thyme using refrigeration, freezing, and drying.
Proper Storage Methods
Proper storage is key to retaining the maximum freshness and flavor of thyme. Here are the recommended techniques:
To store fresh thyme in the refrigerator:
- Trim thyme sprigs to remove dead or damaged parts
- Rinse briefly and pat dry thoroughly with paper towels
- Place sprigs in a resealable plastic bag or storage container
- Optional – Add a damp paper towel inside bag/container to provide humidity
- Refrigerate for up to 1-2 weeks
Keeping thyme refrigerated at 40°F slows moisture and flavor loss. The cold temperature prevents spoilage by inhibiting bacterial growth. Storing cut herbs in an unsealed container allows for some airflow which reduces risk of mold.
Check thyme daily and remove any sprigs that are turning slimy or wilted. Refreshed the damp paper towel as needed to provide humidity without causing excess moisture.
Freezing is one of the simplest ways to preserve fresh thyme for 4-6 months. To freeze:
- Wash thyme sprigs and pat thoroughly dry
- Place on a parchment paper-lined baking sheet and freeze overnight
- Transfer frozen thyme to an airtight container or freezer bag
- Label bag with date and return to freezer
Freezing stops the enzymatic breakdown that causes herbs to lose flavor. Frozen thyme will darken slightly but retains its taste. To use, simply remove desired amount and return remainder to freezer.
Frozen thyme works best in cooked dishes rather than garnishes. Let it thaw 5 minutes before using to prevent mushiness.
Air drying thyme completely removes moisture, allowing it to be stored at room temperature for up to 1 year. You can dry thyme in a food dehydrator or oven at low heat. An easier method is to air dry thyme naturally:
- Wash thyme sprigs gently and dry thoroughly
- Tie stems together and hang bundles upside down in a dry, well-ventilated area
- Leaves should fully dry in 1-2 weeks
- Crumble dried leaves off stems and store in an airtight container
Dried thyme has a more concentrated, intense flavor. Use about half the amount of dried thyme as you would fresh. Keep away from light and moisture to retain maximum potency.
Now that you know how to store fresh thyme correctly, let’s go over how to tell if thyme has gone bad.
How to Tell if Thyme Has Gone Bad
With improper storage, fresh thyme can deteriorate quickly. Signs that thyme has spoiled include:
- Wilting, drooping, or mushy leaves
- Brown or black discoloration
- Slimy texture
- Foul, musty odor
Discard any sprigs that display these traits. Just one spoiled sprig can make an entire batch go bad faster.
If storing in the fridge, closely monitor thyme daily. Small spots of mold or sliminess can appear rapidly. Immediately remove and discard any compromised stems.
For dried thyme, check for lack of aroma, change in texture, or visible mold. Dried thyme that is very old may lose its potency but is still safe to use in larger quantities.
As long as fresh or dried thyme shows no signs of spoilage, it is still usable. But for the best flavor, try to use thyme as soon as possible after purchasing or harvesting.
Tips for Using Fresh Thyme
Here are some tips for enjoying fresh thyme at its flavorful best:
Add to meat, poultry, and vegetables in the last 10 minutes of cooking to retain flavor.
Use sprigs as a bake potato topping. The high heat will gently release the thyme’s aromas.
Combine with olive oil, salt, and pepper for a quick bread dipping sauce.
Toss chopped thyme into salads, grain dishes, soups, and marinades.
Pair with heartier aromatics like rosemary, sage, and oregano in seasoning blends.
Muddle into lemonade, cocktails, and other beverages for flavor.
With proper storage, you can keep fresh thyme on hand for 1-2 weeks. Follow these tips for maximizing the shelf life and enjoying the taste of fresh thyme. Feel free to dry or freeze remaining thyme if you can’t use it all when fresh.
