Note: The ingredients below will make 3/4 to 1 cup of chimichurri sauce.

If you’re using the chimichurri as a finishing sauce (drizzled over cooked steak), 1 cup is typically plenty for 2 lbs. of meat, especially since the sauce is bold and flavorful.
You’ll want extra if you also want to use it as a marinade. Chimichurri used for marinating and topping should be split into two batches (for food safety), and you’ll need about 2 cups total.
