Should I use flank steak or skirt steak?
Honestly, you can use this chimichurri sauce on any cut of steak. It can even be used on pork, chicken or seafood.
In my opinion and based on testing various cuts, skirt steak grilled or seared in a cast iron pan is the best cut of meat for this fresh and tangy sauce.
Flank steak also works well and cooks quickly, but is a leaner cut of meat than skirt steak. Skirt steak has a little more “melt in your mouth” flavor to go with this delicious sauce.
Both flank and skirt steak are great options for an easy steak marinade.

Can I use this chimichurri as a marinade?
Yes, absolutely! But you really don’t need to. After testing it various ways….we recommend just adding it at the end as a fresh sauce.
Marinating is not necessary and just adds an extra step and time. A simple grilled steak seasoned with salt and pepper is all you need!
Spoon this fresh sauce over a hot flank or skirt steak and you’ll know what I mean.

LOVE this chimichurri recipe! I’ve made it 3 times now and it’s just perfect. We end up putting it on our whole meal, not just the steak! I’ve also turned the leftovers into a salad dressing by adding more oil the next day.
Yes, you can put it on just about anything!
