Start by gathering your shallot, red jalapeño, and garlic cloves. Finely chop these ingredients before placing them into a food processor. Add two tablespoons of red wine vinegar for that tangy flavor. Pulse the mixture for about 20-30 seconds, stopping to scrape down the sides, until everything is well minced and nicely incorporated.

Next, remove the processor lid and add a generous handful of fresh cilantro and flat-leaf parsley, along with a teaspoon of oregano and salt to taste. Pulse again for about 15-20 seconds until the herbs are finely chopped but still retain a bit of texture.

With the food processor running on low, slowly drizzle in about half a cup of extra-virgin olive oil. Pulse just until the ingredients are fully combined, which should take no more than 10 seconds.

Taste your chimichurri sauce and adjust the seasoning if necessary by adding more salt or a touch of vinegar for extra zest.

Transfer your vibrant cilantro chimichurri sauce into an airtight container or mason jar. Refrigerate it for about 30 minutes before serving, which allows the flavors to meld beautifully.
