Tzatziki is a Greek dip and condiment that has become mainstream in North America, and there are as many variations of it as there are people making it!

Traditionally, this is a combination of thick and creamy Greek yogurt, cucumber, garlic, and dill. Variations include a splash of olive oil, lemon, red onion, and more.

In this keto-ized version of this famous sauce, I’ve cut the carbs making it a high-protein snack that can be used as a dip, condiment, salad dressing, and more.

You’re only limited by your creativity, and with this versatile Tzatziki recipe, you can make a big batch and dole it out as you need it.

Chef Jenn’s Tips

  • Don’t have fresh dill? Use dried! Use about 2 tsp of dried dill.
  • Like your Tzatziki with a bit of onion? Chop a bit of shallot into the mixture.
  • If you’re using non-fat or low-fat yogurt, add a tablespoon or two of olive oil to bring up the fat content
  • Tzatziki will keep well in the fridge for about a week so put it on everything!

What to Serve With Tzatziki Sauce Keto

I love Tzatziki Sauce (keto) with chicken kebabs, beef kebabs, and with my keto grilled vegetables, and I’ll even add a spoonful to my keto meal prep lunches.

Yes, it sure is! It is loaded with protein and can be a good source of fat if you use full-fat yogurt.

There are 3 net carbs in each generous 1/4 cup serving.
