My homemade chimichurri is a chunky, herby sauce made with fresh parsley, garlic, red wine vinegar, lime juice, oregano, and a pinch of red pepper flakes. I pulse it just a few times in the food processor because I prefer chimichurri with plenty of texture rather than a smooth consistency. It's tangy, garlicky, and especially good spooned over juicy churrasco, but I also use it with chicken, shrimp, and roasted potatoes.
Add all the ingredients to a food processor. Pulse until desired consistency. I'd pulse 2-3 times first and check to see if it's ok. You want the sauce rather chunky, not liquidy. You want texture! If it's not there yet, pulse 1-2 times again. That should do it!
Taste and adjust seasonings. Serve chimichurri sauce with churrasco steak or your favorite chicken, or shrimp recipe. Enjoy!
