You can store cilantro and green onions so they stay fresh for weeks if you treat them right.
The trick is to give them a little moisture, a little airflow, and the right temperature for each herb.
Learning how to store cilantro and green onion properly will save you money and frustration.
You’ll stop tossing slimy, wilted bunches into the trash every week.
In this post, you’ll learn exactly how to store cilantro and green onion in the fridge and freezer, plus common mistakes to avoid.
Let’s keep your herbs crisp and vibrant.
How to Store Cilantro and Green Onion So They Last
Believe it or not, cilantro and green onions are two very different plants, and how you store cilantro and green onion should reflect that difference.
Cilantro is a tender leafy herb that wilts fast, while green onions are sturdier alliums with hollow stalks.
That’s why the best way to store cilantro and green onion starts with understanding what each one hates.
Cilantro hates drying out, and green onions hate excess moisture sitting on their roots.
So here’s how to store cilantro and green onion like a pro.
1. How to Store Cilantro in the Fridge
The most reliable way to store cilantro is the “flower vase” method in your fridge.
Trim the stems slightly, place the bunch in a jar with an inch of water, and cover the leaves loosely with a plastic bag.
This keeps cilantro hydrated without soaking the leaves, which is the number one way to store cilantro and green onion differently.
Change the water every couple of days, and your cilantro can last up to two weeks.
If you don’t have a jar, wrap the cilantro in a slightly damp paper towel and seal it in a zip-top bag.
That’s another easy way to store cilantro and green onion when space is tight.
2. How to Store Green Onions in the Fridge
Green onions are a bit more forgiving, but they still need a smart setup.
The best way to store green onion is to trim the roots, wrap the stalks in a dry paper towel, and place them in a plastic bag in your crisper drawer.
The paper towel absorbs extra moisture, which prevents that nasty slime from forming.
You can also stand green onions upright in a glass with a little water, roots down, and cover the tops with a bag.
This is a fantastic method to store cilantro and green onion together if you’re short on fridge space.
Just change the water every few days so the roots don’t rot.
3. The Mistake That Ruins Both Herbs
Washing cilantro and green onions before you store them is the biggest mistake people make.
Extra water on the leaves and stalks creates a breeding ground for mold and bacteria.
So when you store cilantro and green onion, always wait to wash them until right before you use them.
If you must wash them early, dry them thoroughly with a salad spinner or clean towels first.
That one tip alone will double how long you can store cilantro and green onion in your fridge.
How to Store Cilantro and Green Onion in the Freezer
Sometimes you buy too much and you know you won’t use it all in a week.
That’s when the freezer becomes your best friend for cilantro and green onions.
Freezing changes the texture, so these herbs won’t work as fresh garnishes anymore.
But they’re perfect in soups, stews, sauces, and cooked dishes.
Here’s how to store cilantro and green onion in the freezer the right way.
1. Freezing Cilantro in Oil or Water
Chop your cilantro finely and pack it into ice cube trays.
Cover with olive oil or water and freeze until solid.
Once frozen, pop the cubes into a freezer bag and label them with the date.
This is a smart way to store cilantro and green onion for cooking, because you just toss a cube straight into the pan.
2. Freezing Green Onions in a Bag
Green onions freeze beautifully with almost no prep.
Slice them, spread them on a baking sheet to freeze individually, then transfer to a freezer bag.
You could also learn how to store cilantro and green onion the lazy way by simply chopping both and freezing them together.
They’ll last up to six months in the freezer.
3. Label and Date Everything
Frozen herbs all look the same after a few weeks.
Always write the herb name and freeze date on the bag.
This small habit makes it easy to store cilantro and green onion without guessing later.
A quick glance tells you what’s fresh and what needs to go.
Extra Tips to Store Cilantro and Green Onion Longer
Want to squeeze even more life out of your herbs?
Try these bonus tricks that work every time.
1. Keep Them Away From Ethylene Producers
Bananas, apples, and tomatoes release ethylene gas that speeds up spoilage.
Store cilantro and green onion away from these fruits in the fridge.
This simple separation keeps your herbs greener for days longer.
2. Use the Right Fridge Spot
The crisper drawer is designed for this job.
It controls humidity better than the shelves, which helps you store cilantro and green onion without wilting.
Set the vent to low humidity for green onions and higher humidity for cilantro.
3. Revive Wilted Herbs Fast
If your cilantro looks sad, trim the stems and stand it in cold water for 30 minutes.
Green onions perk up the same way.
Knowing how to store cilantro and green onion also means knowing how to bring them back when they’re fading.
A little cold water works wonders.
So, How to Store Cilantro and Green Onion?
You store cilantro and green onion by keeping them dry, cold, and properly wrapped until you’re ready to use them.
Cilantro loves a jar of water and a loose bag, while green onions prefer a dry paper towel and a sealed bag.
Skip washing until the last minute, keep them away from ethylene-producing fruits, and freeze the extras in oil or bags.
Follow these steps and you’ll always know exactly how to store cilantro and green onion so they stay fresh, flavorful, and ready whenever a recipe calls for them.
