Keto Tzatziki Sauce

This delicious Keto Tzatziki Sauce is a low carb version of one of my favorite sauces. Greek tzatziki sauce is one of those really simple recipes that can be made low carb and keto with just a few simple substitutions.

In this case all I needed to do was sub out sour cream for Greek yogurt and tada! We have a creamy, garlic-y, dill sauce with only 3 net carbs in 1/4 cup. Yum!!

What is in Keto Tzatziki Sauce?

  • Sour Cream – We’ve subbed in sour cream in place of the Greek yogurt. It reduces the carbs even further and adds a little extra fat. With the tang from the lemon juice and vinegar I don’t even notice the difference.
  • Cucumber – You can use regular cucumbers for this but I highly recommend English cucumbers if you can find them. Regular cucumbers will need to be peeled because their skin is tougher and slightly bitter. They also have big seeds which add to the bitterness. English cucumbers don’t have seeds and their skin is soft so they don’t need to be peeled before grating them.
  • Garlic
  • Lemon Juice
  • Red Wine Vinegar
  • Fresh Dill – Authentic Greek tzatziki doesn’t usually have dill in it, I feel like that’s something we Americans added over time, but it’s how I am used to having it when I go out to eat and I love the added flavor that the dill gives the sauce.
  • Salt

How to Make Keto Tzatziki Sauce:

This sauce is so simple to make!

  1. Start by grating the cucumber. You’ll want to make sure you get as much moisture out of it as you can so that it doesn’t make the sauce watery. Place the cucumber in a heavy duty paper towel, cheesecloth, or a clean dish towel, wrap it up, and then squeeze to remove the water from it.
  2. Add the dried cucumber to a large bowl along with all of the other ingredients and then stir to combine.

That’s it! Some people put theirs in a food processor to make the dip smoother but I like the little bits of cucumber. Feel free to do whatever you like best.

Note: The longer you let this dip sit the more the flavors develop. I recommend making it the night before and letting it sit in the refrigerator overnight. If you are in a hurry give it at least 1 hour before using.

What Can I Serve With Keto Tzatziki Sauce?

  • Tzatziki sauce makes a great dip for a veggie platter with cucumbers, bell peppers, carrots, cauliflower, broccoli, etc.
  • It’s also a great addition to our Greek Chicken Roll-ups, Greek Sliders or Keto Chicken Gyro Bowl.
  • Sometimes I just add a tablespoon or two to a bowl of diced tomatoes and cucumbers and stir them all together.
  • Thin the sauce out by adding a little olive oil and it makes an absolutely delicious Greek salad dressing.
