Quality holds for about 1–2 months at 0°F / -18°C. Frozen food stays safe indefinitely; only quality declines.
Yes: tarragon keeps 1–2 months in the freezer at 0°F (-18°C), compared with 7–10 days in the fridge.
How to freeze tarragon
- Leafy greens and herbs lose their crunch when frozen.
- For cooking, blanch greens or chop herbs into ice-cube trays with oil or water.
- Add straight from frozen to soups, sauces and stir-fries.
How to thaw tarragon
In the fridge
Move it to the fridge the night before; this keeps texture best.
At room temperature
Only for shelf-stable items; perishable food should not thaw on the counter.
From frozen
Many foods can go straight into soups, sauces, smoothies or the oven.
Freezer vs fridge vs counter
What freezing does to tarragon
Leaves are thin and full of water, so they collapse when frozen. They cannot be used for salads afterwards, but blanched greens and herbs frozen in oil keep their flavour well for soups, sauces and stir-fries.
Tarragon storage times by method

About tarragon
Tarragon belongs to our vegetables category. USDA FoodKeeper has no separate entry for tarragon. It is covered by “Herbs” (fresh herb), so this page uses that entry’s storage times. According to USDA FoodKeeper, it keeps 7–10 days in the fridge and 1–2 months in the freezer. It is not a high-risk perishable food, so the main concern is quality rather than safety. Where to keep it: the crisper drawer holds humidity, which keeps produce from wilting.
Leafy greens and fresh herbs are mostly water held in thin leaves, so they wilt and spoil faster than almost any other produce. The two things that shorten their life are too much moisture, which turns leaves slimy, and too little, which makes them wilt. Stored dry, cold and loosely wrapped, they keep for days to a couple of weeks.
Why tarragon goes bad
Bacteria and moulds break down leaf tissue that has been damaged by bruising or excess water, producing the slimy, dark patches and sour smell of spoiled greens. Leafy greens are also a known carrier of E. coli and Listeria from the field, which is why bagged salads should be kept cold and used by their date.
Common tarragon storage mistakes
- Storing greens wet after washing.
- Packing them tightly so leaves bruise.
- Keeping them near ethylene-producing fruit.
- Freezing them for salads; frozen greens are only good for cooking.
How to pick fresh tarragon
- Choose crisp leaves with no slime, yellowing or dark spots.
- Check bagged salad for liquid in the bag and a date well ahead.
- Buy herbs with perky stems and a fresh smell.
Tarragon: use it up in time
- Wilt soft greens into soups, pasta, curries and omelettes.
- Blend herbs into pesto or freeze them in oil in ice-cube trays.
- Add a handful to smoothies.

Expiration dates, decoded
Most dates printed on tarragon packaging are about quality, not safety. In the US, the only federally required date is the use-by date on infant formula; everything else is chosen by the manufacturer. “Best if used by” tells you when flavour and texture are at their best. “Sell-by” is for the shop's stock rotation and you can store food at home for its normal storage time after it. “Use-by” is the last date the manufacturer recommends for peak quality.
That is why this page counts storage time from the day you buy, cook or open tarragon, rather than from the printed date: 7–10 days in the fridge. If food has been stored correctly, it can be fine past a best-by date; if it has been stored badly, it can spoil well before it.
How long has your tarragon been frozen?
Still safe, and at the end of its best-quality window. Use it in the next few weeks; texture and flavour fade after 1–2 months.
Food kept frozen solid stays safe indefinitely, but after 3 months expect freezer burn and dull flavour. Fine for soups, sauces and baking; trim dry grey patches.
Food kept frozen solid stays safe indefinitely, but after 6 months expect freezer burn and dull flavour. Fine for soups, sauces and baking; trim dry grey patches.
Assumes -18°C (0°F) or colder. Frozen food stays safe; these verdicts are about quality.
True or false? Tarragon myths
- Correct!Not quite.
Partly true. Tarragon is not high-risk, so a little past 7–10 days usually means lower quality, not danger. Check for mould and off smells first.
- Correct!Not quite.
False. Freezing pauses bacteria; it does not kill them. They become active again as the food thaws, so thaw in the fridge and cook or reheat properly.
- Correct!Not quite.
True. Quality holds for about 1–2 months at 0°F / -18°C. Frozen food stays safe indefinitely; only quality declines.
- Correct!Not quite.
False. The door warms up every time it opens. The crisper drawer holds humidity, which keeps produce from wilting.
- Correct!Not quite.
Not for safety, but it keeps it at best quality longer. Follow the storage times on this page.
Tarragon shelf life, answered
How long does tarragon last in the fridge?
7–10 days at 4°C (40°F) or colder. Keep it sealed so it does not pick up moisture or odours.
How long does tarragon last in the freezer?
1–2 months for best quality at -18°C (0°F). Frozen food stays safe indefinitely; after that, texture and flavour fade.
How long does tarragon last at room temperature?
It is not meant to be kept at room temperature. Refrigerate it.
How long is tarragon good for past the expiration date?
Tarragon past its best-by date is usually safe if stored well; check smell, look and taste before using.
How can you tell if tarragon is bad?
A sour or rotting smell from the bag or bunch. Slimy, wet or wilted leaves that do not perk up in cold water. Dark green-black or brown leaves.
