Notes
Is Chimichurri Served Hot or Cold?
Chimichurri tastes best at room temperature. So if you refrigerate it, bring it out of the refrigerator an hour before serving to let it come to room temperature.
Can I Make Chimichurri Sauce Ahead?
Yes, you can make it up to a day ahead. Cover and store in the refrigerator. Take it out of the refrigerator an hour before serving to let it come to room temperature.
