Flank Steak with Chimichurri Sauce

Growing up in a small town in the Midwest, we weren’t exposed to exotic, Argentinian fare like this chimichurri sauce. It’s a vibrant green condiment full of herbs, garlic, a splash of vinegar and olive oil. Fabulous stuff.

Not all versions contain cilantro, but since I’m a fan, I included that along with some Italian, or flat-leaf, parsley, and oregano. Whizzed up in the blender, it’s ready in a matter of minutes.

I sprinkled some of my homemade taco seasoning over our flank steak, drizzled with a bit of olive oil and sent Bill to grill it to a medium-rare. After a short resting stint, I sliced the meat on the diagonal and topped with this gorgeous herb sauce. Such an outstanding pairing with beef!

The Verdict

I could see the picky hubby eyeing the “green stuff” on his beef. It certainly was a far cry from his usual ketchup. I loved everything about this chimichurri sauce. In fact, I was happy to nibble on the leftover bits on the serving plate. Bill was neutral and Nick, the other carnivore in residence this summer, thought it was “pretty good.” Baby steps.

I was delighted that the ketchup stayed in the fridge. I will keep this in my back pocket for our next dinner party. I’ll have Bill grill a number of flank steaks and this sauce will be one of the options!
