Add all ingredients to a food processor, and puree until smooth.
For best results, wait at least 2 hours (at room temperature) before use to let the flavors develop.
Drizzle it over mains or sides, like grilled steak or chicken, or roasted potatoes.
Notes
Storing: Homemade chimichurri sauce lasts about a week in the refrigerator; store in a lidded container like a Mason jar. Bring to room temperature before use.
Don't taste it right away. I personally think this chimichurri sauce tastes like grass clippings immediately after making. It NEEDS time to sit before it tastes truly awesome.
Serving up success. This easy chimichurri sauce is seriously AH-mazing paired with grilled steak, grilled chicken thighs, and even grilled vegetables.
