What is chimichurri sauce?

Chimichurri sauce is an uncooked herbaceous sauce from Argentina that is traditionally served with grilled meats.

It is traditionally made with parsley but it can sometimes be made with both parsley and cilantro.

For this recipe I opted to add some cilantro because I love the big burst of flavor it brings to the sauce.

How do I make chimichurri sauce?

All you need to do is add the ingredients to a food processor and blend!

If you don’t own a food processor you can also use a high powered blender.

How to cook chimichurri flank steak?

My favorite way to prepare this recipe (and most steak recipes!) is by grilling them!

It turns out perfectly and makes for a very little cleanup. Which, if you live in my house you know that is the ultimate dinner objective.

For this recipe I like to lightly marinate the meat, preheat the grill to medium-high heat, grill on both sides until browned, let rest, slice, and then serve with the remaining chimichurri sauce.

I typically cook my meat until medium rare which is about 4 minutes per side.

However, your cook time will depend on the thickness and size of your flank steak.

How do I store leftover grilled flank steak?

If you have any leftover flank steak I like to keep it in an airtight container in the refrigerator for up to 3 days.

You will also want to store any leftover chimichurri sauce in the fridge as well. However, the oil might harden a bit from the cooler temperatures so let it rest at room temperature until the oil is melted.
