How to Make Cilantro and Onion for Tacos
Learning how to make cilantro and onion for tacos is easier than you think, and it all starts with the right ingredients.
Here’s what you’ll need and how to bring it all together.
1. Choose Fresh Cilantro and White Onion
The base of cilantro and onion for tacos is, well, cilantro and onion.
For the onion, white onion is traditional because it has a sharp, crisp bite that softens slightly with lime.
Red onion works too if you want a milder, more colorful version.
For the cilantro, look for bright green leaves with firm stems and no yellowing or wilting.
Freshness matters here because cilantro and onion for tacos is a raw topping, so there’s no cooking to hide behind.
2. Wash and Dry Everything Thoroughly
Cilantro can hold a lot of grit and sand, so rinse it well under cold water.
A salad spinner or a few pats with a clean kitchen towel will dry it off.
Drying is key because wet cilantro and onion for tacos turns soggy fast, and nobody wants a watery taco.
Give the onion a quick rinse too, then pat it dry.
3. Chop the Cilantro Finely
Bunch the cilantro leaves together and chop them finely with a sharp knife.
You want small, even pieces so every bite of your cilantro and onion for tacos gets that fresh herbal hit.
Some people include the tender stems, and that’s totally fine since they carry plenty of flavor.
Just avoid the thick, woody stems near the bottom.
4. Dice the Onion into Tiny Pieces
Cut the onion into very small dice, roughly the same size as your chopped cilantro.
Uniform pieces mean the cilantro and onion for tacos distributes evenly across every taco.
If raw onion tastes too strong for you, soak the diced onion in cold water for 10 minutes, then drain and pat dry.
This mellows the bite while keeping the crunch.
5. Mix with Lime Juice and Salt
In a bowl, combine equal parts chopped cilantro and diced onion.
Squeeze in fresh lime juice, about half a lime for every cup of the mixture, and sprinkle in a pinch of salt.
Toss gently so the cilantro and onion for tacos is coated but not bruised.
The acid brightens everything up and helps the flavors meld together.
