The flavor difference is even more dramatic.
Cilantro has a bold, fresh, citrusy flavor that can dominate a dish.
Parsley is considerably milder. Flat-leaf parsley has a fresh, grassy flavor with a slightly bitter or peppery edge.
This is why substituting one for the other can completely change a recipe.
If a recipe specifically calls for cilantro and you use parsley instead, the dish may still taste good—but it won’t have that distinctive cilantro character.
Why Do Some People Think Cilantro Tastes Like Soap?
This is one of the most interesting things about cilantro.
Most people recognize its characteristic citrusy, herbal flavor, but some people perceive cilantro as tasting strongly like soap.
Research and nutrition references have linked this perception to genetic differences affecting how certain aldehyde compounds are detected.
So if cilantro tastes strange or soapy to you, you’re not necessarily imagining it. Your perception of its aroma and flavor can genuinely differ from someone else’s.
Where Is Cilantro Used?
Cilantro is especially popular in cuisines where its bright, powerful flavor complements spicy, acidic, and aromatic ingredients.
You may find fresh cilantro in:
- Salsa
- Guacamole
- Tacos
- Curries
- Fresh chutneys
- Asian-inspired dishes
- Soups
- Rice dishes
- Salads
- Marinades
It is often added toward the end of cooking or used fresh as a garnish because its delicate leaves and strong aroma are best appreciated when they aren’t subjected to prolonged cooking.
Where Is Parsley Used?
Parsley is one of the most versatile kitchen herbs.
Flat-leaf parsley can be added to:
- Soups
- Stews
- Salads
- Pasta
- Sauces
- Marinades
- Dressings
- Meat dishes
- Vegetable dishes
- Stocks
Its flavor is much more subtle, making it useful when you want freshness without dramatically changing the flavor of the dish.
Don’t Confuse Cilantro With Coriander Seeds
Here’s another source of confusion.
Cilantro and coriander come from the same plant, Coriandrum sativum.
In American English, the fresh leaves and stems are commonly called cilantro, while the dried seeds are called coriander.
In many other English-speaking regions, however, the word “coriander” can refer to both the fresh herb and the seeds.
So when following an international recipe, it’s worth checking whether the recipe means fresh coriander leaves or coriander seeds.
They have completely different appearances and flavors.
Can You Substitute Parsley for Cilantro?
Sometimes, but don’t expect the same result.
Parsley can provide freshness and a green herbal note, but it won’t reproduce cilantro’s distinctive citrusy flavor.
Likewise, cilantro isn’t always a good substitute for parsley because its much stronger flavor can take over a dish.
If a recipe calls for a small amount of parsley as a garnish, cilantro could dramatically change the finished dish.
How to Keep Fresh Cilantro and Parsley Longer
Fresh herbs can wilt quickly, but proper storage can help.
After bringing them home, remove any damaged leaves and keep the herbs refrigerated.
One practical approach is to wrap them loosely in a slightly damp paper towel and place them in a container or bag that allows some airflow.
Avoid leaving them soaking wet, because excess moisture can encourage spoilage.
Another useful habit is to wash only the amount you plan to use immediately and keep the remaining herbs relatively dry until needed.
The 10-Second Grocery Store Test
The next time you’re standing in the produce section, remember these three steps:
1. Look.
Cilantro usually has softer, rounder-looking leaf lobes. Parsley has more pointed, sharply serrated leaves.
2. Feel.
Cilantro tends to be more delicate, while flat-leaf parsley is generally sturdier.
3. Smell.
Rub a leaf gently. A strong citrusy, distinctive aroma points to cilantro. A mild grassy aroma points to parsley.
That’s it.
You don’t need to memorize complicated botanical details.
So, Which One Would You Pick?
If you chose number 1, congratulations—you picked the cilantro.
Number 2 is flat-leaf parsley.
The two herbs may look almost identical when you’re standing several feet away, but once you know the difference in their leaves and especially their aromas, the grocery-store mystery becomes much easier.
And the next time someone asks, “Which one is cilantro?” you can simply pick up a leaf, give it a gentle rub, and let the aroma answer the question.
Did you get number 1 right? Or have you ever accidentally bought parsley when you needed cilantro?
