Chimichurri – A Humble Steak Sauce

Chimichurri with steak, basting butter and sauce.

What is the BEST steak sauce? There are loads of options for steak sauces including béarnaise, demi-glace, peppercorn sauce, Diane sauce and salsa verde to name a few. My favourite steak sauce will always be a proper demi-glace jus but this is difficult and time consuming to make at home. It’s best to leave this to the professionals and order this sauce at a proper restaurant that knows what they are doing.

At home I want something light, healthy and preferably something I can also make on the grill. Here is my recipe for a grilled spring onion chimichurri steak sauce.

What is Chimichurri?

Originating from South America, chimichurri is a popular green steak sauce that is served room temperature and consists mainly of parsley, garlic and red wine vinegar. You can definitely add any other herbs you wish including oregano, cilantro or even mint.

Why Chimichurri?

I love this steak sauce because it packs a little heat from the jalapeño and it’s full of fresh herb flavour. You can make this sauce pretty quickly and it’s a healthier alternative to steak au poivre or the classic béarnaise sauce. Chimichurri is the exact sauce I want to eat outside with a nice grilled steak when the weather is scorching hot.

In this recipe I’ve added some grilled spring onions to add a little sweetness and extra smokiness into the sauce. Also there’s no way I’m putting cilantro in this because I hate cilantro, but of course you can add this if you like.

Thoughts on Authenticity

Should a recipe be authentic? What does authentic really mean? I don’t understand why a recipe needs to be authentic. If it is authentic to only add red wine vinegar in this recipe and not lime juice – who care’s? Authenticity doesn’t guarantee good food, it guarantees lack of innovation. If we are never allowed to experiment with new variations, we will never have new ideas. Also, everyone has different tastes. If you like your chimichurri with lime juice instead of red wine vinegar, then that’s okay! The most important part is that you like the sauce, not somebody else.

Steak and raw ingredients for chimichurriTips for a Better Steak

Let the steak rest at least 5 minutes in a warm place. 
This is crucial. When you let the steak rest, the juices cool and thicken slightly so when you go to slice your steak you don’t have the juices spilling out everywhere.

Salt the steak right before you cook it and not too far in advance.
The salt will draw moisture from the steak and the water will prevent you from achieving a nice grilled colour.

Always buy dry-aged if you can.
Dry aged steaks have less moisture and therefore more intense flavour. They also grill beautifully but are always more expensive.

Dry your steak well.
The secret to a good steak is controlling the moisture. Too much moisture will result in a grey-looking steak instead of a nicely charred exterior.

Add the pepper to the steak after its cooked.
If you add the pepper before you grill you will burn it. Some people like this, but I think it’s nicer to have the taste of fresh black pepper rather than burnt pepper.

Baste the steak with butter and vinegar as it cooks

I like to brush the steak after every turn with a mixture of butter and vinegar. This gives it a bit extra flavour and makes a beautiful grilled crust on the outside. One knob of butter mixed with 1 Tbsp red wine vinegar should do it.

  • Chop the green spring onion tops and add it to the food processor with all the ingredients except the vinegar and half the jalapeño. Blend everything in pulses, because we want to keep the sauce rustic and not too fine.

  • Taste everything. Add the vinegar until you like the taste but it's not too strong that you can't taste anything else. You want to taste the fresh herbs, the spicy kick from the jalapeño and the sweetness from the grilled onions. If you would like it spicier, add the rest of the jalapeño. Place the finished chimichurri in a bowl and add a drizzle of olive oil over the top. Serve at room temperature with your favourite steak!
