Three green sauces show up on most restaurant menus and in most home cooks' rotations: chimichurri, salsa verde, and pesto. They all use olive oil and green herbs. They are not the same thing, they do not substitute for each other, and using pesto where chimichurri belongs is a small crime against grilled meat. Here is exactly what makes each of them different.
Quick answer
Chimichurri is Argentinian, parsley and dried oregano based, loose and oily, uncooked, served over grilled meat. Italian salsa verde is parsley, capers, and anchovies, loose but salty and umami, served over poached fish or boiled meat. Pesto is Genoese, basil and pine nut based, thick and creamy from parmesan, tossed through pasta. Same green colour, three different flavour worlds and three different use cases.

What each one actually is
Chimichurri
Argentina's answer to "what do we put on grilled meat". Fresh flat-leaf parsley chopped by hand, dried oregano, minced garlic, dried chilli flakes, sea salt, black pepper, red wine vinegar, and extra virgin olive oil. Everything raw, everything rested for at least 30 minutes so the flavours integrate. The finished sauce is loose and oily with distinct herb pieces suspended in it. You spoon it, you do not pour it.
Chimichurri exists to sit next to a grill. The whole logic is: the meat is heavy, salty, and rich; the sauce is bright, sharp, and herbaceous; the two together are the balance. It is a raw sauce over hot meat, always at the table, never in the pan.
For the full recipe see Pedro's family chimichurri recipe. For the ready-made version, Pedro's Chimichurri uses the same ingredients in a 200ml jar.
Italian salsa verde
Not the same as Mexican salsa verde (which is tomatillo based). Italian salsa verde is a herb-and-caper sauce from northern Italy. Fresh parsley (usually flat-leaf), capers, anchovies, garlic, sometimes hard-boiled egg yolk, sometimes stale bread as a thickener, olive oil, vinegar or lemon.
Traditional pairing is bollito misto (a plate of poached meats), poached fish, or roasted vegetables. It is saltier and more umami than chimichurri thanks to the capers and anchovies. It has almost no heat.
Pesto (Genoese)
A sauce, not a paste, in Italian technique, though it reads as a paste to Australian palates. Fresh basil pounded in a mortar with pine nuts, garlic, extra virgin olive oil, sea salt, and grated hard cheese (parmesan and pecorino traditionally). The result is thick, creamy, and rich. It is designed to coat pasta.
Pesto is not typically served next to meat in Italy. It goes on pasta, into minestrone, on bruschetta, occasionally over gnocchi. Its texture is wrong for anything hot and heavy that you want to cut through.
The Argentinian answer to "what makes chimichurri different"
Four things distinguish chimichurri from every other green sauce.
- Vinegar-forward. Chimichurri hits you with acidity in a way pesto never does and salsa verde only sometimes does. The red wine vinegar is deliberately assertive.
- Herb-fresh, not paste. Chimichurri stays loose. You can see individual parsley leaves and garlic pieces. This is the opposite of pesto, which is deliberately smooth and creamy.
- Oil-loose. The oil in chimichurri is not emulsified with anything. It floats above the herbs. You stir it before serving and it separates again as it sits. This is correct.
- Uncooked. Never heat chimichurri. This is also true of the other two green sauces, but chimichurri is the strictest about it.
When to use each
| You are cooking | Use |
|---|---|
| Steak, grilled chicken, chorizo, lamb chops | Chimichurri |
| Empanadas (baked, fried, or reheated) | Chimichurri |
| Poached fish, boiled meat, cold roast beef | Italian salsa verde |
| Roasted root vegetables | Either salsa verde or chimichurri |
| Pasta, gnocchi, minestrone | Pesto |
| Bruschetta or a cheese board | Pesto |
| Sourdough with olive oil | Chimichurri drizzle |
| Fried eggs or avocado toast | Chimichurri |
Substituting: what happens if you swap
Pesto on steak
Wrong texture, wrong flavour. The cheese and pine nut richness clings to the meat instead of cutting through it. The result is heavy on heavy. Not disastrous, but nobody would ask for it in Argentina.
Chimichurri on pasta
The vinegar destroys pasta. Do not.
Salsa verde on empanadas
Works, but the anchovies confuse the beef in the empanada. Chimichurri is the intended partner.
Pesto in a chimichurri jar
Argentinians would call you out.
Where chimichurri fits in Argentinian eating
Chimichurri is not a special-occasion sauce in Argentina. It sits on the table at every asado, every empanada dinner, every family lunch. It is closer in cultural role to how Australians relate to tomato sauce than to how anyone relates to pesto. Everyone has an opinion on the best version, most families make their own, and the ready-made jar in the fridge is the emergency backup.
See chimichurri with steak for the deeper cultural context, or the Argentinian table for how chimichurri sits inside the wider meal.
Pedro's ready-made jar
If you want the Argentinian version without making it from scratch, Pedro's Chimichurri is made in Bondi Beach in small batches using the traditional recipe. Fresh parsley, dried oregano, garlic, red wine vinegar, extra virgin olive oil, chilli. Vegan and gluten-free. 200ml jar, keeps 2 weeks refrigerated once opened. Adds to any empanada order to help meet the $48 minimum.
FAQ
Is chimichurri the same as salsa verde?
No. Chimichurri is Argentinian, parsley-and-oregano based, vinegar-forward. Italian salsa verde is parsley-and-caper based, sometimes with anchovies. Mexican salsa verde is tomatillo based, a different sauce entirely.
Can I use pesto instead of chimichurri?
Not really. The texture (thick vs loose), fat profile (cheese and pine nut vs pure olive oil), and flavour direction (basil-rich vs parsley-oregano-vinegar) are all different. Pesto belongs on pasta. Chimichurri belongs over grilled meat.
Is chimichurri healthier than pesto?
Chimichurri has no cheese or nuts, so it is lower calorie per spoon. Both are olive oil based. Chimichurri is vegan and dairy-free by default. Pesto contains parmesan.
Can I make salsa verde in an Argentinian style?
You can, but then it is chimichurri. If you add capers and anchovies to chimichurri, you have made Italian salsa verde. The two are close cousins on a different flavour track.
Which is the oldest of the three sauces?
Pesto has the longest continuous history (Genoa, centuries). Italian salsa verde also has centuries of tradition. Chimichurri's origins are debated, with variations traced through 19th-century Argentinian gaucho cooking.
