What is Tzatziki Sauce?

How Do You Make Tzatziki Sauce Keto-Friendly?

To make tzatziki sauce keto-friendly, simply make sure that you are using full-fat yogurt. Check the labels and go with the brand that has the lowest carbohydrates. If you like, another option is to use sour cream in place of the traditional yogurt.

How Many Carbs are in Tzatziki Sauce?

The number of carbohydrates will vary by recipe. This one has a little less than 2 net carbs per serving.

Can You Make This Recipe Ahead of Time?

Yes! This is a great recipe to prepare ahead of time. I like to make it at least four hours before serving to give the flavors a chance to blend in the refrigerator. Salting the cucumber keeps the dip from getting too watery so that you can keep it in the fridge for about four days.

Can I Skip Salting the Cucumber?

You can, but I don't recommend it. Cucumber is about 96% water. Salting cucumber helps the vegetable to release some of its water. If you skip salting, you will end up with Tzataki that is watery and will continue to get more watery the longer it sits. This means it won't last as long in the refrigerator.

Do I Need to Seed the Cucumber?

Yes - for best tasted and texture, I recommend seeding them. The seeds add little flavor and are very watery. To seed a cucumber, peel it and half it lengthwise. Run a small scoop inside each half to scoop out the seeds.

What are the Best Cucumbers for Tzataki?

I prefer American cucumbers that are dark green. Seedless English Cucumbers have less flavor.

How to Make Keto Tzatziki Sauce

Start by salting the cucumber to release water. To do this, place the seeded and chopped cucumber in a colander over a bowl. Sprinkle with salt and let stand for 10 minutes.

Use a clean dishcloth to wring out as much liquid as you can.
