Keto Tzatziki by Chef Alexa of KetoLuxe

My recipe for Keto Tzatziki is an adaptation of a recipe that the Mother and my sister Quinn learned in Greece. 


About ten years ago, my sister Quinn performed at the Half Note in Athens. She and the Mother stayed at a hotel where they ate a lot of Tzatziki. The Yiayia who did all of the cooking for them shared her recipe. When they returned home, the Mother went on a tzatziki frenzy. We ate it on everything: salmon, chicken, shrimp, chips, and anything else that held still.

Keto Tzatziki by Chef Alexa of KetoLuxe

Chef Alexa shreds and drains English cucumber to make this recipe fail-proof. No need to deseed or worry about a watery sauce. 

Now that we eat keto, I had to revise the recipe to be low carb. There was no way I was going to live without my favorite condiment. I swap out yogurt with all natural sour cream to knock out those carbs. This recipe is gluten-free, sugar-free, and delicious. To me, the best flavor is when the Tzatziki is made the day before, making it a perfect party or meal prep food.
