Making it couldn’t be easier. You simply puree together fresh herbs like cilantro, oregano and parsley with olive oil, red wine vinegar, garlic and chili flakes in a food processor or blender until smooth. Ideal as a sauce on top of any grilled meat, I decided to use it as both a marinade and a topping for this super tender and juicy grilled flank steak.


It was a huge hit at a recent BBQ I hosted for friends and is sure to be a regular menu item all summer long. Ideal for using up fresh herbs growing in the garden, you can prepare the chimichurri sauce up to 7 days in advance to save time during mealtime.

  1. Oh god it makes me sad to see that americans have no idea about south america. Nobody in Brazil has ever heard about this sauce, the mexican and brazilian kitchens are completely different! Not a good article to relate to the olimpic games…
    Best regards from Rio de Janeiro.

    1. Hi Vanessa, I’m sorry that this recipe made you sad. Please don’t let my grilled flank steak blog post affect how you feel about my entire nation. :) As stated, I know this dish isn’t from Brazil but it is from South America which is home to the Olympics. Either way, I’m sorry that my steak recipe made you sad. Best of luck with the Olympics! I would love to visit your beautiful region one day – was trying to go this fall but had to cancel due to the Zika virus but would love to go one day when they find a vaccine. Thanks again for writing and have a great rest of your week.

  2. Sooooo, If I eat this every day from now until the 2020 Olympics, think I can make the swim team? I’ve always wanted to look good in the little tight hats.

    Seriously, though, love a perfectly cooked healthy steak – and this is just that! Perfect (and I bet killer for leftovers too!)

  3. This chimichurri sauce sounds great (I’ve seen a lot of recipes that don’t sound good at all). I just wish that my husband liked marinated steaks, but that’s not likely to happen. At least I could make the sauce to serve with the steak, which would allow me to enjoy it.
