Keto Tzatziki Sauce Recipe

This creamy, cool and refreshing tzatziki sauce is great on everything – meats, vegetables, fish, etc. With my Keto Tzatziki Sauce Recipe you can have all the flavors you crave without the extra carbs!

Low-Carb Tzatziki SauceWhile my Keto Tzatziki Sauce is simply amazing, I didn’t set out intending to create a low-carb recipe adaptation…. So, here’s the thing – I actually stink at keeping anything beyond the basics on hand. For me plain yogurt, let alone greek yogurt, isn’t something that I regularly have in the fridge…

And then, when I REALLY need ingredients last minute, it never fails that it’s impossible to find the healthiest options locally. In this case finding Organic, Grass-fed, Whole Milk Yogurt (let alone pre-strained greek) isn’t available in a moments notice.

No. I never eat low fat or fat free dairy so please don’t even ask about it. Full Fat or Don’t Bother, for reals, follow my lead folks.

Don’t get me wrong, our local food scene has evolved and I’m extremely proud of how far we’ve come BUT there’s a certain degree of planning required.

But I do ALWAYS have sour cream in our fridge – I purchase it by the case so that I’m never caught without it!

And why the heck wouldn’t sour cream work for Tzatziki Sauce!?!

Am I right? or Am I RIGHT??

I mean come-on.. Why didn’t you think of this already?? Using Sour Cream will make the thickest, creamiest Tzatziki Sauce and you’ll never go back to using greek yogurt again, even if you ditch the keto diet in the future!

Follow my lead and make this GIANT 2 cup batch because you’ll want to put my Keto Tzatziki Sauce on EVERYTHING.

To start with serve it up with my Gyro Lamb Meatballs, a generous side of my 5-mintue Pressure Cooker Rice Pilaf with Pine Nuts and Parsley and don’t forget a Greek Salad with piles of Kalamta olives too!!

    This is amazing. I like the sour cream, i think even better than yogurt. (Watch out sams club, i think i will be buying the 5lb tubsof s.cream from now on) The only thing I did differently was add the zest of the lemon and 1- 2 tbsp olive oil. Thanks for a great recipe..we are having it with grape leaves tonite

  5. Yahoo! So glad to find this recipe. I make my own Greek-style, very thick yogurt and reserve the whey for soaking chicken (a la ‘buttermilk’ chicken). I love this sauce and totally love Gyros in any form. This is a keeper.
