This chimichurri, a classic Argentine sauce, is based on the authentic and traditional recipe. Vinegar, olive oil, parsley, oregano, garlic, and pepper flakes are whisked together in minutes. Tweak slightly to taste. Bring on the steak.

We’re keen on dousing, drizzling, and otherwise acquaint this emerald elixir with grilled steak, chicken, chops, seafood, or heck, just about anything. While some traditional chimichurris call for a 1:1 ratio of vinegar to oil, this one dares to tilt things in favor of being more acidic. The line you choose to walk with regard to how much vinegar to add depends in part on your tolerance for tang and in part on whether you intend to use it as a marinade or drizzling sauce (opt for more vinegar for the former, less for the latter). So try it as-is. Then, if need be, tweak it ever so slightly and try, try again. We find it to be the perfect basis for just about any use.Renee Schettler Rossi

How Do You Say Chimichurri?

We’re going to be snarky for a second. Chimichurri is, by definition, a sauce. So to say “chimichurri sauce” is a little redundant. Sort of like saying “Tuna Melt Sandwich” or “Frosted Flakes cereal.” Imagine the time you’ll save in your life not adding those extra five letters each time you say “chimichurri” in conjunction with grilled steak, chicken, salmon, pork, shrimp, or anything else you can drizzle or douse with this fetching green sauce!

  • 3/4 cup sherry vinegar
  • 1/2 cup olive oil
  • 3/4 cup chopped flat-leaf parsley leaves
  • 3 tablespoons chopped oregano leaves
  • 6 large cloves garlic chopped
  • 1/2 teaspoon red pepper flakes
  • 3/4 teaspoon salt


  • In a large nonreactive bowl or a glass jar, combine the vinegar, oil, parsley, oregano, garlic, red pepper flakes, and salt. Taste and, if desired, gently adjust the amount of vinegar, oil, and salt accordingly.
  • Serve the chimichurri immediately or refrigerate in a covered container. If chilled, allow the sauce to return to room temperature before serving. It can be kept in the fridge for a week, but we doubt it will last that long.

I made this recipe in the worst of all possible scenarios: for a friend who spends half the year in Uruguay in South America, and who’s addicted to chimichurri. In short, she loved it. As we said above, this particular version is definitely tangy with vinegar. It’s also thin. So I added more olive oil (about 1/2 cup) and it balanced out the vinegar and made it a bit more viscous. By the end of the meal we were dipping everything into it, including potatoes, bread, even our fingers.

One note: Refuse to use the food processor. This needs the rough chop of a knife.

Recipe Testers’ Reviews

I think chimichurri is one of those sauces that has many variations, and people prefer slight differences — more garlic, less pepper, thicker sauce, looser marinade. This is a looser sauce, with an emphasis on the vinegar, which I feel works well when marinating steak. It also makes a lot, again due to its use as a marinade here. It comes together really quickly (I suspect you could even throw everything into a food processor for a couple of whirls) and gave the steak a bright, fresh flavor. I’d recommend reserving more than just 1/3 cup, though, for drizzling. We dipped bread into it, drizzled it over grilled corn, even spooned it on eggs the next morning.

I really liked this recipe as written. I kept the ratio of oil to vinegar as-is, as I didn’t find it too vinegary BUT I make my vinaigrettes more to a half and half ratio, which many might consider too tart. I really appreciated this vinegary, parsleyed, garlicky marinade and sauce with the charred smokiness of the steak, and wouldn’t change a thing. Very easy and simple and works perfectly with beef.

Sherry vinegar is one of my favorite vinegars ever, and I’m happy to use it whenever I can. Its flavor really came through for me — in a good way. Sometimes chimichurri (and other marinades and sauces) can be assertively vinegary, but this combination was a great ratio. The recipe calls for 2/3 cup, but I used 3/4 cup, and I also increased the 1/4 cup olive oil to 1/2 cup. Perhaps next time I’ll try cider vinegar out of curiosity.

Recipes that require fresh herbs appeal to me as I grow many of our own. Fresh oregano has sort of a mustiness to it, but when teamed up with the remaining ingredients it was subtle yet added that flavour so traditional in chimichurri. The red pepper flakes and garlic make this really sing!

The chimichurri tasted good even before adding flank steak to the equation, which is telling. Chimichurri + flank steak = delicious.

    We love this. I never have sherry vinegar, so I use sherry and balsamic vinegar. I marinate my meats then i usually reduce the sauce and serve it with the steak.

    I’ve had several Chimichurri sauce disasters and tonight I had some special rib eyes from a rancher friend and figured that I could put my faith in David Leite–so I made this recipe with a few adaptations. I didn’t have red pepper flakes so I used some fresh cayenne. I didn’t have sherry vinegar so I used brown rice vinegar. I did about 25% more parsley and garlic than called for, but my garlic was elephant garlic and a little less intense. The sauce was amazing! Oh, and I think that doing all the chopping by hand makes a huge difference.

    1. Robin, thank you for your confidence in me–and us! This sauce is a winner, and we have Costa Rican friend who visits Argentina often, and she swears by it. And I think your version sounds incredible.

  3. just wordsmithing here (once an editor, always an editor): do you really mean acerbic, or do you mean acidic? Both words work, but they actually describe different flavor profiles, actually –I should say–taste profiles.

    1. that’s a very good question, beth. you’re right, acerbic leans more toward sour or bitter, acidic more towards, well, acidic, yes? i shouldn’t have relied on a single word and instead taken a few more words to explain that some testers simply felt the higher dose of vinegar was just too vinegary for their tastes. i guess this can fall under either camp, but more towards acidic, yes? many thanks for helping ensure we’re as clear as can be…

  4. What’s the closest to sherry vinegar, apple cider vinegar, plain old vinegar or balsamic vinegar? Thanks.

    1. Depends on how acerbic you like things, Ellen. You could use an apple cider vinegar if you like a slight tang, but I’d recommend balsamic. If you have it, a white balsamic could be really quite nice, not just because it keeps the chimichurri from turning a rather drab brown but because it has a slightly less slam-you-in-the-face-with-a-baseball-bat vinegar effect. Let us know what you decide…

      1. I’ve been using this recipe for a while now, not knowing I was a closet Argentinian. I’ve been substituting balsamic for sherry vinegar, adding a solid slug of bourbon (natch) & a dash of dark brown sugar. I’ve also used the concotion as a marinade, adding thin sliced onions (sometimes orange zest) and then letting steaks, chops, chicken swim around in the goop for times ranging from 2 hours up to 24 depending on type of meat & state of organization. Grilled with some good grilled sausage along side…must be why those Argentinian cowboys alway look so damned frisky.
