How to Keep Cilantro Fresh in the Refrigerator for Two to Three Weeks
Treat cilantro like cut flowers, not like lettuce
Cilantro wilts fast because it is mostly water and has thin, delicate stems. The moment you bring it home, it starts losing moisture. The best way to keep it fresh is to store it upright in a jar with water at the bottom—the same way you would keep a bouquet of flowers. This method keeps cilantro crisp for two to three weeks, far longer than wrapping it in paper towels or plastic bags.
The water method works because the stems can absorb moisture directly, replacing what the leaves lose to the air. Cilantro stored this way stays green and flavorful much longer than cilantro stored dry. You will notice the difference within a few days.
Key Takeaways
- Store cilantro upright in a jar with about an inch of water at the bottom, covering the lower stems but not the leaves.
- Cover the cilantro loosely with a plastic bag to trap humidity around the leaves while allowing some air circulation.
- Change the water every three to four days to prevent bacterial growth and keep the stems from rotting.
- Keep cilantro away from ethylene-producing fruits like apples and avocados, which speed up wilting.
- Cilantro stored this way lasts two to three weeks, compared to three to five days in a sealed plastic bag.
The water jar method step by step
Fill a glass jar or drinking glass with about an inch of room-temperature water. Trim the bottom half-inch off the cilantro stems with a sharp knife—this removes any bruised or dried tissue and opens the stem to absorb water more easily. Stand the cilantro upright in the jar so the lower stems are in the water but the leaves stay dry and above the waterline.
Loosely drape a plastic bag over the cilantro without sealing it. The bag traps humidity around the leaves, which slows water loss, but you want a little air to move through so the stems do not rot. Secure the bag loosely around the jar with a rubber band or just let it sit over the top. Place the jar in the coldest part of your refrigerator—usually the back of a shelf, not the door.
Change the water every three to four days. As cilantro sits in water, bacteria and fungi can grow and clog the stem, preventing water uptake. Fresh water keeps the stems open and the plant hydrated. You will see the cilantro perk up noticeably after a water change.
Why the plastic bag matters
Cilantro leaves lose water to the air around them. A plastic bag creates a humid microclimate that slows this loss. However, a completely sealed bag traps too much moisture and can cause the stems to rot or the leaves to develop mold. The loose drape is the balance—it reduces water loss without creating a wet, airless pocket.
If you notice condensation pooling inside the bag or the stems looking slimy, loosen the bag further or remove it for a few hours. The goal is visible moisture on the leaves, not standing water inside the bag.
Keeping cilantro away from ethylene producers
Ethylene is a gas that ripening fruits release. It speeds up the aging process in nearby plants, including cilantro. Apples, avocados, bananas, and tomatoes are strong ethylene producers. If your cilantro jar sits next to a bowl of apples or near the produce drawer where you keep avocados, the cilantro will wilt faster.
Store your cilantro jar on a shelf away from these fruits. If your refrigerator is small and space is tight, at least keep them on different shelves. This simple separation can add several days to cilantro's life.
What to do if cilantro starts to wilt
If you notice the leaves drooping but the stems are still firm and the water is clear, the cilantro is thirsty. Change the water immediately and trim another quarter-inch off the bottom of the stems. Cilantro often revives within a few hours of fresh water.
If the stems feel slimy or smell sour, the cilantro has begun to rot and should be discarded. Slime means bacteria have taken over and the plant cannot recover. This usually happens when the water has not been changed in more than a week or when the jar was sealed too tightly.
Freezing cilantro for longer storage
If you have more cilantro than you can use in three weeks, freezing extends its life to several months. Wash and dry the cilantro completely, then chop it finely and spread it on a baking sheet. Freeze for two to three hours until solid, then transfer to a freezer bag or airtight container. Frozen cilantro works well in cooked dishes like soups, curries, and salsas, but the texture becomes soft and it is not suitable for fresh garnishes.
Another option is to make cilantro ice cubes: blend fresh cilantro with a little water or olive oil, pour into ice cube trays, and freeze. Pop out the cubes and store them in a freezer bag. Each cube is a single portion ready to drop into a pot or blender.
Comparing storage methods
| Storage Method | Lasts How Long | Best For | Setup Time |
|---|---|---|---|
| Water jar with loose plastic bag | 2 to 3 weeks | Regular use, fresh garnishes | 2 minutes |
| Sealed plastic bag in crisper drawer | 3 to 5 days | Short-term storage only | 1 minute |
| Paper towel wrap in plastic bag | 5 to 7 days | Moderate use, some moisture control | 3 minutes |
| Frozen chopped cilantro | 3 to 4 months | Cooked dishes, long-term storage | 15 minutes plus freezing time |
Frequently Asked Questions
Can I store cilantro in the crisper drawer instead of on a shelf?
Yes, the crisper drawer is actually a good location because it maintains higher humidity than the rest of the refrigerator. Use the water jar method there if you have room. If you prefer not to use a jar, wrap the cilantro loosely in a damp paper towel and place it in a plastic bag with a few small holes punched in it. This lasts about a week.
Should I wash cilantro before storing it?
Wash it only if it is visibly dirty. Extra moisture on the leaves speeds up rot, especially if you then seal it in a bag. If you must wash it, dry it thoroughly with paper towels or a salad spinner before storing. For the water jar method, you can wash it right before you use it.
Why does cilantro smell bad after a few days even though it looks okay?
Smell usually means bacteria are growing in the water or on the lower stems. Change the water immediately and trim off the bottom inch of stems. If the smell returns within a day, the cilantro is beginning to rot and should be discarded. Always change the water every three to four days to prevent this.
Can I store cilantro at room temperature?
Not for long. Cilantro wilts within hours at room temperature because the warm air pulls moisture from the leaves. Always refrigerate it. The water jar method works at room temperature for a day or two if you are using the cilantro quickly, but the refrigerator extends its life dramatically.
Is it okay to store cilantro with the roots still attached?
Yes, and roots actually help. If your cilantro came with roots, keep them on and store the whole plant upright in water. Roots can absorb water just like cut stems, and they may even regrow small leaves if the plant is healthy. Trim the roots slightly if they are very long or matted.
