You can preserve cilantro in olive oil by chopping it up and freezing it in ice cube trays.
This simple method locks in that fresh, vibrant flavor for months.
If you’ve ever watched your bunch of cilantro turn slimy in the fridge after just a few days, you’re not alone.
It happens to the best of us.
But here’s the good news: preserving cilantro in olive oil is one of the easiest kitchen hacks you’ll ever learn.
It takes about ten minutes of hands-on work and saves you from tossing out wasted herbs week after week.
In this post, we’ll walk through exactly how to preserve cilantro in olive oil, plus a few tips to make the process even smoother.
Let’s get into it.
Why Preserve Cilantro in Olive Oil?
Preserving cilantro in olive oil works so well because the oil creates a protective barrier around the herb.
That barrier keeps air away, and air is the main enemy of fresh cilantro.
When oxygen hits chopped cilantro leaves, they oxidize, turn dark, and lose that bright, citrusy punch.
Olive oil stops that from happening.
Here’s why this method deserves a spot in your routine.
1. It Keeps Cilantro Fresh for Months
A bunch of cilantro in the fridge lasts maybe a week if you’re lucky.
Cilantro preserved in olive oil, on the other hand, keeps for three to six months in the freezer.
That means no more emergency trips to the store just because a recipe calls for a handful of fresh cilantro.
2. It Saves You Money
How many times have you bought a big bunch of cilantro, used two tablespoons, and watched the rest wilt?
Preserving cilantro in olive oil means you use every last leaf.
Nothing goes to waste, and your grocery budget notices.
3. It’s Ready to Use Instantly
When you preserve cilantro in olive oil, you’re basically making pre-portioned flavor bombs.
Toss one into a hot pan for sautéed vegetables, stir it into soup, or melt it over grilled chicken.
There’s no chopping, no washing, no prep work at dinner time.
It’s all done already.
How to Preserve Cilantro in Olive Oil Step by Step
Ready to preserve cilantro in olive oil yourself?
Here’s the whole process from start to finish.
1. Wash and Dry the Cilantro Thoroughly
Start by giving your cilantro a good rinse under cool water.
You want to remove every bit of dirt and grit hiding in those stems.
Then dry it well.
A salad spinner works great, or you can pat the leaves dry with a clean kitchen towel.
Excess water is a problem because it can turn into ice crystals later and dilute the flavor.
2. Chop the Cilantro
Once your cilantro is dry, chop it up.
You don’t need to be precise here.
A rough chop is perfectly fine, stems and all, since the stems carry plenty of flavor too.
Just run your knife through the bunch until you’ve got small, manageable pieces.
3. Pack It Into Ice Cube Trays
Now grab an ice cube tray.
Spoon the chopped cilantro into each cup, filling them about three-quarters of the way.
Don’t press it down too hard.
You want a little breathing room so the oil can work its way into every gap.
4. Cover With Olive Oil
Pour olive oil over the cilantro until each cup is completely full.
Every single leaf should be submerged.
That’s the whole secret behind how to preserve cilantro in olive oil successfully.
If any leaves poke above the surface, they’ll darken and spoil.
Use a decent everyday olive oil here, nothing too fancy, since you’ll be cooking with it.
5. Freeze Until Solid
Slide the tray into your freezer and leave it for a few hours, or overnight.
Once the cubes are rock solid, you can pop them out and transfer them into a freezer bag or airtight container.
Label the bag with the date so you know how long they’ve been in there.
6. Store and Use Within Six Months
Cilantro preserved in olive oil stays at its best for about six months.
After that, it’s still safe to eat, but the flavor starts to fade.
When you’re ready to cook, just grab a cube and drop it straight into the pan.
No thawing needed.
Tips for Preserving Cilantro in Olive Oil
A few small details make a big difference when you preserve cilantro in olive oil.
1. Use Fresh, Healthy Cilantro
Start with the best cilantro you can find.
Look for bright green leaves and firm stems, and skip any bunches that are yellowing or wilted.
You can’t preserve cilantro in olive oil and get great results if the herb was already on its way out.
2. Add a Little Garlic or Lime (Optional)
Want to level up your cilantro cubes?
Drop a tiny piece of minced garlic or a squeeze of lime juice into each cup before adding the oil.
It’s a game changer for soups, tacos, and marinades.
3. Try Different Herbs the Same Way
The same technique works for parsley, basil, mint, and dill.
So once you’ve mastered how to preserve cilantro in olive oil, you’ve basically unlocked a whole system for saving fresh herbs.
So, How Do You Preserve Cilantro in Olive Oil?
You preserve cilantro in olive oil by chopping the herb, packing it into ice cube trays, covering it completely with oil, and freezing it.
It’s a quick, affordable way to keep that fresh cilantro flavor on hand for months.
No more wilted bunches, no more wasted money, and no more last-minute store runs.
Give it a try the next time you bring home a big bunch of cilantro, and you’ll wonder why you didn’t start preserving cilantro in olive oil sooner.
