Why I Made This Tzatziki
This week's menu included garlic butter pita chips to go with my white bean tomato cucumber salad, and I realized I needed some tzatziki on the table too.
This low fat tzatziki is cool, creamy, and ready in minutes. Using low fat Greek yogurt keeps it lighter while still giving the sauce a thick texture.
All you need is a cup of Greek yogurt, a cucumber, a lemon, a little fresh dill, and a garlic clove.
Do You Need to Strain the Yogurt?
Greek yogurt is already thicker than regular yogurt, so you may not need to strain it. However, low fat Greek yogurt varies by brand and can contain more liquid than full-fat yogurt.
If your yogurt looks thin or watery, spoon it into a fine-mesh strainer lined with cheesecloth or a clean kitchen towel. Set the strainer over a bowl and let the yogurt drain for 1-2 hours. Discard the liquid before making the tzatziki.
Also squeeze as much liquid as possible from the grated cucumber. This is the most important step for keeping your low fat tzatziki thick and creamy.

What You Need
- Low Fat Greek Yogurt - Use thick 2% Greek yogurt. If the yogurt looks watery, strain it before making the tzatziki.
- Persian Cucumber - Persian cucumbers have fewer seeds and less water. If using a standard cucumber, peel and seed it before grating.
- Fresh Lemon Juice - Adds fresh, tangy flavor. White vinegar can be used as a substitute.
- Garlic - One small clove adds plenty of flavor without overpowering the sauce.
- Fresh Dill - Gives tzatziki its classic fresh, herby flavor. Chop it finely so it blends evenly.
- Kosher Salt and Black Pepper - Season the sauce to taste and bring out the other flavors.
- Extra Virgin Olive Oil - Adds richness and gives the sauce a smooth, creamy finish.
Instructions
Grate the cucumber on the large holes of a box grater.

Place the grated cucumber in a clean towel, and squeeze out as much liquid as possible.

In a medium bowl, whisk together the yogurt, garlic, lemon juice, olive oil, dill, salt, and pepper. Fold in the drained cucumber until well combined.
Taste and add more salt or lemon juice if needed.
Serve immediately, or cover and refrigerate for 1 hour to let the flavors blend. Stir before serving.

Top Tips for Success
