I loooove keto Tzatziki Sauce. It’s so good on so many things, and I almost always have some in the fridge – and it’s perfect for anyone on a keto diet. This low-carb Tzatziki Sauce can also be used as a salad dressing, a marinade, a sauce, and even just for dipping your favorite veggies.

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! It 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 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 keto Tzatziki recipe, you can make a big batch and dole it out as you need it.

Keto Tzatziki Sauce is Good with everything!

Tzatziki pairs REALLY well with grilled chicken and fish, but I also serve it with my Greek meatballs, or just fun dippers like cucumber slices, carrot or celery sticks, and more. It’s fabulous with grilled meat, smoked beef, on top of chaffwiches (chaffle sandwiches) and so much more!

Ingredients To Make Keto Tzatziki Sauce

  • Greek yogurt – Make sure you’re getting PLAIN Greek yogurt, with no sugar added.
  • Cucumber – I like using English cucumbers because you can eat the peel and the seeds are tiny.
  • Salt – Kosher salt is my first pick.
  • Garlic – Fresh garlic is best!
  • Dill – Fresh dill adds so much flavor to this keto Tzatziki Sauce recipe.
  • Lemon juice – A tiny bit of fresh lemon juice goes a long way!

Chef Jenn’s Tips

  • Don’t have fresh dill? Use dried! Use about 2 tsp of dried dill.
  • Like your easy keto 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 Greek Tzatziki Sauce

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.

Is Tzatziki Sauce Keto?

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

How many carbs are in keto Tzatziki sauce?

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

How long does it take to make low-carb Tzatziki Sauce?

The longest part is draining the cucumbers, which take about 30 minutes. Then, you just mix and serve!

    I’m a sucker for any Greek inspired food, so I was thrilled to find this recipe. I used it with some grilled chicken and had a garden salad on the side. It all got mixed together in a fabulous way. Thanks for the recipe!

  3. 5 stars
    You are right this tzatziki sauce is good on anything. I made it to go with kabobs and had leftovers so I used it for a veggie dip the next day. Love how easy this is to make.
