Balsamic Flank Steak with Chimichurri Sauce

Feel the summer grilling vibes all year long with this Balsamic Flank Steak with Chimichurri Sauce!

This post was created in partnership with our friends at Tessemae’s.

Stop what you’re doing.

It’s time to talk steak and summer and grilling for just a minute. Okay, maybe two minutes because steak and summer and grilling!

Guuuuuys! It’s finally here. The official unofficial first day of summer came and went last week and I hardly noticed. Besides that, it’s been raining and cool here in Boulder until now. Yay! Summer’s a comin’ … and pretty soon I’ll be complaining that it’s just too hot. Yeah, you too? #miserylovescompany

But that’s not the point. The point is this Balsamic Flank Steak with Chimichurri Sauce that takes just minutes to prep, 4-24 hours to marinate and just a few more minutes to grill. Please don’t let it take just a few minutes to eat – it’s worth savoring.

To keep things really simple and Whole30-compliant I marinated the flank steak using Tessemae’s Organic Balsamic Vinaigrette. Sure, I could have mixed up my own marinade using oil, vinegar, and spices but tossing the steak into a zip-top bag, dousing it with a pre-made dressing & marinade then tossing it in the fridge to do its thing took me less than 5 minutes to do and no dishes.

Don’t have any Tessessmae’s Balsamic Vinaigrette on hand? Don’t worry, you can also use our Homemade Balsamic-Herb Steak Marinade and get perfect results every time.

Get your own Tessemae’s dressings, marinades and sauces here or at your local Whole Foods, Target and many local grocery chains nationwide – which you can find using the Tessemae’ Store Locator)

Now let’s talk about this Chimichurri Sauce

I first tasted chimichurri in Argentina in 2003. It was unlike anything I’d ever had before. Until then I’d never really used parsley in cooking or as a plate garnish back in my restaurant and catering days. But this sauce –  a blend of fresh parsley, garlic, lemon, salt and oil was intoxicating. Especially served over thinly sliced beef steak.

For those of you new to chimichurri, it’s like pesto. Only without the basil, cheese or pine nuts. Ok, so maybe it’s not really like pesto but it looks like pesto and it’s still fresh herbs + oil + acid + salt like pesto. It’s like South American pesto, mmkay?!

And it’s absolutely perfect when generously spooned over grilled Balsamic Flank Steak served a top Grain-free Cauliflower Rice Tabbouleh. Like summer in a bowl.
