Yes, eventually. Expect dill to keep 7–10 days in the fridge, or 1–2 months if frozen. Poor storage can cut that short, and once it turns, the warning signs listed below will give it away.
Warning signs that dill has spoiled
Odor
A rotten or sour smell coming from the bunch or the bag.
Texture
Leaves that are soggy, slimy or limp and won't revive in cold water.
Color
Leaves turning brown or a blackish dark green.
Mold
Fuzz anywhere in the bag means the whole bag should go.
Eating dill after the printed date
Best-by vs. sell-by
Counting from the purchase date, FoodKeeper allows unopened dill 7–10 days in the refrigerator. Labels such as "best-by" and "sell-by" are about peak quality and how stores rotate stock, not about safety — infant formula is the one product whose use-by date federal law requires.
Past the printed date
Dill kept in good conditions is generally still safe after its best-by date. Before use, inspect the odor, appearance and flavor.
Making dill last longer
- Keep it dry: wrap it in a paper towel and tuck it into a bag or container.
- Keep it in the crisper drawer, with the fridge set to 40°F (4°C) or colder.
- Stand parsley, cilantro and similar herbs upright in a jar of water, drape a loose cover over them and refrigerate.
How long dill keeps with each storage method
| Storage | How long | Temp | Packaging | Good to know |
|---|---|---|---|---|
| Refrigerator | 7–10 days | ≤ 40°F / 4°C | Airtight | 40°F (4°C) or colder |
| Freezer | 1–2 months | 0°F / -18°C | Wrapped or freezer bag | 0°F; for quality, not safety |
Getting to know dill
Dill sits in the vegetables section of our food guide. USDA FoodKeeper has no separate entry for dill. It is covered by “Herbs” (fresh herb), so this page uses that entry’s storage times. Going by USDA FoodKeeper, it lasts 7–10 days in the fridge and 1–2 months in the freezer. It falls into the lower-risk group, so storing it well is mostly about keeping quality rather than about safety. Best storage spot: the crisper drawer keeps moisture in, and that humidity stops produce from going limp.
Salad greens, cooking greens and fresh herbs are little more than water held in thin leaves, which is why they droop and break down faster than nearly any other produce. Two things cut their life short: excess moisture turns the leaves slimy, while a lack of it makes them go limp. Stored cold and dry in loose wrapping, they last from a few days up to a couple of weeks.
What makes dill spoil
When leaves are bruised or sitting in excess water, bacteria and molds break down the damaged tissue, causing the dark, slimy spots and sour odor of greens that have spoiled. Greens can also arrive from the farm carrying E. coli or Listeria, so bagged salads need to stay cold and be eaten by their date.
Mistakes people make storing dill
- Putting greens away while they are still wet from washing.
- Cramming them into a container so the leaves get crushed and bruised.
- Storing them close to fruit that gives off ethylene.
- Freezing greens meant for salad; once frozen, they are only suitable for cooking.
Choosing good dill at the store
- Look for crisp leaves without slime, yellow edges or dark spots.
- With bagged salad, check that there is no liquid inside and that the date is well in the future.
- Pick herbs whose stems stand upright and that smell fresh.
Dill: ways to finish it in time
- Wilt tender greens into a curry, soup, omelet or pasta dish.
- Blitz herbs into pesto, or pack chopped herbs into ice-cube trays, top with oil and freeze.
- Toss a handful into a smoothie.
Making sense of expiration dates
The dates printed on dill packaging mostly describe quality rather than safety. Under US rules, infant formula's use-by date is the only one federal rules require; manufacturers choose all the others themselves. A “Best if used by” date marks when flavor and texture are at their peak. A “Sell-by” date helps the store rotate its stock, and once it passes you can still keep the food at home for its usual storage time. A “Use-by” date is the manufacturer's own pick for the final day of best quality.
For that reason, the storage times on this page start counting from the moment you open, cook or buy dill, not on the date stamped on the package: 7–10 days in the fridge. Food that was stored properly can still be good after a best-by date, while food that was handled carelessly can go bad long before it.
The best place for dill
The crisper drawer keeps moisture in, and that humidity stops produce from going limp.
Inspect your dill
No boxes ticked? That's encouraging. Even so, confirm how long it has been stored, because the germs behind food poisoning can't be seen with the naked eye.
Even one of these means it has spoiled. Toss it, and never taste it to find out.
Your dill storage questions
How long does dill last in the fridge?
7–10 days when held at 4°C (40°F) or below. Seal it well so it stays free of moisture and fridge odors.
How long does dill last in the freezer?
1–2 months at -18°C (0°F) for peak quality. It remains safe for as long as it stays frozen; past that point, flavor and texture slowly decline.
How long does dill last at room temperature?
Room-temperature storage does not suit it; keep it in the fridge.
How long is dill good after the expiration date?
Dill kept in good conditions is generally still safe after its best-by date. Before use, inspect the odor, appearance and flavor.
How do you know if dill is bad?
A rotten or sour smell coming from the bunch or the bag. Leaves that are soggy, slimy or limp and won't revive in cold water. Leaves turning brown or a blackish dark green.
Dill myths: fact or fiction?
- You got it!Not this time.
Partly true. Because dill is low-risk, going slightly beyond 7–10 days usually costs quality rather than safety. Look for mold and sniff for off odors first.
- You got it!Not this time.
False. The freezer puts bacteria on hold rather than killing them. They start up again as the food warms, so let it thaw in the fridge, then cook or reheat it all the way through.
- You got it!Not this time.
True. Held at 0°F / -18°C, it keeps its best quality for roughly 1–2 months. Food that stays frozen remains safe indefinitely; only the quality slips over time.
- You got it!Not this time.
False. Each time the fridge is opened, the door heats up. The crisper drawer keeps moisture in, and that humidity stops produce from going limp.
- You got it!Not this time.
Not for safety reasons, but refrigeration keeps it at peak quality for longer. Go by the storage times listed on this page.
