This Keto Chimichurri is extremely versatile as a sauce, marinade, or even a salad dressing, plus it’s super simple and only takes 10 minutes to prepare!

This Keto Chimichurri is a recipe every person on a LCHF diet should have in their repertoire. It's extremely versatile as a sauce, marinade, or even a salad dressing and it’s super simple to prepare. This recipe is unique for me because the sauce itself doesn’t use a cast-iron skillet, but the steak and carnitas you’re going to make to go with it can be, so…loophole?
We thought that we should start adding a few basics to the site that we use frequently, things like this keto chimichurri, homemade mayonnaise, salad dressings, marinades, etc. We're calling this series Cast Iron Keto Basics {Click here to check it out}


What is chimichurri?
Chimichurri originated in South America (Argentina/Uruguay), and it pairs perfectly with most cuts of meat for a “South of the Border” feast. If you’ve never tried chimichurri before it is loaded with healthy fats from the olive oil and the dominant flavors are garlic and cilantro, and parsley.
How to use Chimichurri
- Drizzle it over skirt steak for a homemade meal that would cost $$$ out at a restaurant. (Pro Tip: add a lobster tail and melted butter for the ultimate surf & turf feast. IIFYM a glass of red wine too, we would suggest a Malbec but it’s totally up to you!)
- Grilled chicken thighs with chimichurri is a weekly staple for us
- Pour it over a bed of sautéed spinach, piled high with your favorite veggies and fresh mozzarella #yum
- Drizzle it over carnitas, this is the perfect protein for keto as it’s 75% fat and 25% protein

What is the serving size?
M says
It says this recipe makes 12 servings, so I guess we can divide the yield by 12 to figure it out? I think weighing and dividing might be easier than volume measures
Mo says
How much is a serving?
Diane says
Excellent, I am not a fan of "heat" so I left out the chilies and the pepper flakes. Worked great as a marinade on steak, I added 2 TBS Mayo and 2 TBS Sour cream (from a Martha Stewart recipe) makes a great salad dressing.

Speaking of lobster with drawn butter - I am now dairy free. Do you think this sauce would taste good on the lobster?
Cast Iron Keto says
Yes! It would be fantastic with lobster.
