I just realized not only is it Cinco de Mayo (yes, I’m getting this post out very last minute but whataya do), but it’s also Taco Tuesday!!! Double whammy! And in honor of both of these occasions, I’m sharing a MAJOR bomb taco recipe, Chimichurri Steak Tacos with Charred Onions. I’ll also note, my husband just walked in the room after eating some of these leftover tacos, and stated “best tacos you’ve ever made.” I have no doubt you’ll love them too!

The secret to these ulta tasty tacos? One word. Chimichurri. It’s truly the shining star in this taco recipe. I shared a recent post all about this magic green herby sauce. You can find it here. Chimichurri is a traditional Argentinian condiment served with grilled meat. It’s made with fresh herbs, olive oil, red wine vinegar, garlic, and spices. It’s just a few ingredients and the flavor is out of this world. It’s herby, vibrant, slightly tangy and has a little garlic punch. It pairs perfectly with the seared meat, charred onions, jalapenos and feta in these tacos. It seriously does not get much better than this flavor combo.
