Tzatziki sauce recipe keto


  • Cucumber – one medium cucumber to add freshness and crunchiness

  • Lemon juice – adds acidity and brightness
  • Extra-virgin olive oil – brings amazing flavor and richness that complements fresh lemon and cucumber

  • Salt – enhances flavor and balances the lemon juice
  • Black pepper – adds a spicy kick that complements other flavors in the sauce

Substitutions and Variations

Homemade keto tzatziki sauce is delicious as written in the recipe card below. However, you can switch things up depending on personal preferences and what you have available in your fridge and pantry. 

Check out these alternative ingredients you can use for this recipe:

  • No Greek yogurt? No problem – try using sour cream instead. It has a tangy flavor similar to Greek yogurt and works well in this recipe.
  • Use red wine vinegar instead of lemon juice. It has a similar acidic flavor to lemon juice and adds a tangy note to the sauce.
  • Swap the olive oil with avocado oil. It’s a healthy oil that is high in monounsaturated fats and has a mild flavor that won’t overpower the other ingredients.
  • Change up the herbs. Fresh parsley, mint, or even chives can jazz up this keto condiment.

In its original form, Greek tzatziki sauce is already keto, low carb, low-oxalate, and GAPS compliant. It’s a wonderful gluten-free condiment that pairs well with many foods. 

For a dairy-free or vegan tzatziki sauce, you can use coconut yogurt instead of Greek yogurt. Coconut yogurt has a similar texture to Greek yogurt and is also low in carbs.

  • Keto diet – This recipe is naturally low-carb and keto-friendly as long as you use full-fat Greek yogurt.
  • Dairy-free – Use coconut yogurt instead of Greek yogurt.
  • Paleo diet –  If following a strict Paleo diet, substitute Greek yogurt with coconut yogurt. If you tolerate dairy, source the best quality full-fat Greek yogurt your budget allows.
  • Low oxalate diet – All ingredients are low-oxalate ingredients.
  • GAPS – This recipe is naturally GAPS-compliant if yogurt is free from gums and additives. Homemade yogurt is best if on strict GAPS protocol.
  • Whole30 – Substitute Greek yogurt with coconut yogurt.

Is tzatziki gluten-free?

Yes, tzatziki sauce is typically gluten-free as it is made with gluten-free ingredients such as yogurt, cucumber, olive oil, and herbs. Therefore, it is appropriate to refer to it as “Gluten-free tzatziki sauce”. However, it is always best to double-check the ingredients of storebought tzatziki sauce to ensure that it does not contain any gluten.

Step-By-Step Directions

Follow these simple directions, and you can’t go wrong! This keto-friendly tzatziki sauce comes together in a few minutes. All you need is a grater for the cucumber and a large bowl to mix everything.

Step one: Grate

Start by slicing the cucumber lengthwise and scooping out the seeds with a spoon. Discard the seeds – this will help remove excess moisture from the cucumber and help avoid a watery tzatziki sauce.

Next, grate or finely mince the cucumber. Alternatively, you can use a food processor for quicker results. Wrap the grated cucumber in a cheesecloth, a clean kitchen towel, or several layers of paper towel and squeeze the excess moisture out gently.

Because of the high water content, the cucumbers will release a lot of moisture when combined with other ingredients resulting in a tzatziki sauce that is too watery. Removing as much excess liquid from the cucumber as possible by discarding the seeds and squeezing out the liquid is important.

Step two: Mix   

In a medium mixing bowl, combine the strained cucumber with Greek yogurt, lemon juice, extra-virgin olive oil, minced garlic, and chopped fresh dill. Mix well until all ingredients are well combined. Add salt and pepper to taste.

Step three: Chill

Once the easy keto tzatziki sauce is combined, it’s important to refrigerate it for at least 30 minutes to allow the flavors to meld together. Transfer to an airtight container or serving bowl and cover with plastic wrap and pop it in the fridge for at least 30 minutes or overnight. The longer you refrigerate the sauce, the better the flavors will be.

In a pinch, you can serve immediately. However, the flavors are best after at least 30 minutes of chill time.

This keto tzatziki sauce is perfect for serving with grilled meats, roasted vegetables, or as a dip for veggies or flax crackers. It is also a great topping for low-carb pita bread or as a keto condiment for sandwiches or wraps like Keto Lamb Gyros

To store low-carb tzatziki sauce, transfer it to an airtight container and store it in the refrigerator. The sauce will last up to three days when stored this way.

Low-Carb Tzatziki Sauce FAQ

Can you make tzatziki without cucumber?

While cucumber is a key ingredient in tzatziki sauce, it is possible to make a variation of the sauce without it. Some great options are grating zucchini or summer squash and squeezing out the excess liquid. You can also omit the cucumber all together and double up on the lemon juice and fresh dill.

What is a good dill substitute for tzatziki?

If you don’t have fresh dill on hand, you can use other fresh herbs like mint or parsley as a substitute. You can also use fresh chives as they have a similar mild onion flavor to dill and makes it a great substitution. Any of these fresh herbs will work well in this recipe. Alternatively, you can use dried dill, but the flavor will not be as pronounced as with fresh dill.

How to make tzatziki sauce without yogurt?

Traditional tzatziki sauce is made with Greek yogurt, but if you are looking for a dairy-free or vegan option, you can use cashew or coconut yogurt instead. Another option is to use avocado blended with lemon juice and olive oil for a creamy, dairy-free alternative.

Can you freeze tzatziki?

Unfortunately, keto tzatziki sauce does not freeze well due to the high water content in the cucumber. When thawed, the sauce will become watery and lose its texture. But thankfully, this simple recipe can be whipped up in no time so there is no need to freeze this keto sauce.
