This cool and creamy tzatziki sauce is full of Mediterranean flavor and so easy to make! It’s made with sour cream instead of yogurt for extra tang and fewer carbs.

Have you ever had Greek cucumber yogurt sauce? It’s a condiment that’s traditionally made with yogurt, cucumbers, garlic, and salt for a cool and refreshing taste.
But yogurt is a controversial ingredient in the low-carb community. That’s why I prefer to make my tzatziki sauce with sour cream!
Just like the traditional sauce, this version is perfect for dipping fresh vegetables. You can also serve it with grilled meats like chicken, beef, pork, and lamb. It’s a perfect sauce to add cool and tangy flavor!
And this recipe is so easy to make. You can be ready to serve it in 10 minutes or less!
How to make tzatziki with sour cream
The creamy low-carb sauce comes together in just a few simple steps:
- Without removing the skin, grate the cucumber.
- Squeeze as much moisture out of the grated cucumber as possible.
- Add sour cream, grated cucumber, fresh dill, garlic powder, and fresh lemon juice to a small bowl. Stir well to combine ingredients.
Enjoy immediately or cover and store in the refrigerator. The sauce will be even better after it’s had time to chill.
How to prepare the cucumber
Did you know that cucumbers are 95% water? That’s why it’s so refreshing to eat them raw.
But you don’t want all that liquid going into a keto tzatziki sauce. The key to this recipe is to remove as much of the moisture from the grated cucumber as possible.
To do this, I recommend taking a handful of grated cucumber at a time and squeezing it between your palms over the sink. Set it on a paper towel until you’re ready to use.
Alternatively, you could add the grated cucumber to a fine mesh sieve and press with paper towels to squeeze out the liquid.
Finally, you could salt the cucumbers to draw out the water. Add the grated cucumber to a sieve over a bowl, toss with salt, then allow it to sit for about 15 minutes.
Once the time is up, press with paper towels or the back of a spatula to release even more water.
If you use the salting method, you may want to reduce the amount of salt you add to the recipe.
Serving Suggestions
I like using sour cream in this recipe to keep the tzatziki sauce low in carbs. That means it’s great to pair with other keto foods.
An easy option is to serve it as a dipping sauce for freshly chopped low-carb vegetables. Keto friendly dippers like my parmesan crisp recipe would be nice as well.
It’s also fantastic with anything you cook on the grill! The smoky flavor combined with the cool tang of the sauce is so delicious. Looking for a fun option for dinner? Make some keto friendly gyros! Just grill up your protein of choice, add it to a coconut flour tortillas, then top it off with some feta and tzatziki!

So tasty’. As I didn’t have green yogurt was happy to find this gem! And didn’t have fresh dill but used a half tbsp of dill weed
Theresa Owens
It was perfect for my gyros 🥙 ❤️
Tam
This is delicious! I hate yogurt so I always make mine with sour cream. This is a great recipe. Thank you!
Kristina
Made this as I had no Greek yogurt in the fridge. It tasted great! I would definitely recommend getting the excess water out of the cucumbers as suggested and making this recipe. Very easy and tasty.
Stephanie
Tastes great!
Arty
This is not Tzatziki; there’s no dill and the key to the bit is fresh garlic. This is a dip for potato chips.
Lisa MarcAurele
It’s more of a Tzatziki substitute that’s keto-friendly.
TalkFood
Um. There’s dill in the recipe.
Darlene Young
There is 2 tablespoons of fresh dill in the recipe written above

I have so much zucchini right now so this is perfect! I love tzatziki so I’m going to put this on everything!
Raia
One of my favorite condiments! I love it on sandwiches, with veggies… by the spoonful… haha.
Yang
I love tzatziki sauce! So versatile and tasty to go with everything off the grill.
Anastasia Papapetros
Sorry honey but this is no way tzatziki and should not be referred to as such! Tzatziki is traditionally made with yoghurt NOT sour cream. This is a sour cream dip with dill and cucumber! As a Greek I am insulted that you would even consider giving it that title!
Lisa MarcAurele
The reason is because sour cream has less carbs than yogurt. But Greek yogurt can certainly be used for a traditional style.
Anastasia Papapetros
Oh honey, you completely missed my point. Regardless of the carbs the fact of the matter is that authentic tzatziki is made with GREEK YOGHURT and not with sour cream. This recipe should be called something more appropriate.
Lisa MarcAurele
I do get that and the recipe can still use Greek Yogurt for those who don’t worry about carbs.
Steve
Get off your high horse
Jean Choi
