1-First step: Prep the potatoes Start by scrubbing the potatoes well. If they are small, quarter or halve them so they cook at the same pace. Place them in a large pot and cover them with cold water by about 1 inch. Add 1 tablespoon kosher salt to the water. Starting with cold water helps the potatoes cook evenly instead of turning mushy on the outside before the center is done. Bring the pot to a boil over medium-high heat, then lower it to a steady simmer. Cook the potatoes until they are fork-tender, usually about 10 to 12 minutes depending on their size. Drain them well and let them sit for a few minutes so excess steam can escape. That little pause helps the dressing cling better later.

2-Second step: Make the tzatziki-style dressing While the potatoes cook, prep the cucumber. Grate or finely chop the 1/2 medium English cucumber, then squeeze out as much liquid as you can using a clean kitchen towel or paper towels. This is a key step because too much water will make the salad thin and soggy. If you want a thicker salad for meal prep, this step matters even more. In a large bowl, mix the Greek yogurt, cucumber, scallions, dill, lemon juice, olive oil, grated garlic, 1 teaspoon kosher salt, and black pepper. Stir until smooth and well blended. Taste the dressing and add a little more salt or pepper if needed. The mix should taste bold because the potatoes will soften the flavor once combined.

3-Third step: Combine while the potatoes are warm Once the potatoes are drained and slightly cooled, add them to the bowl with the tzatziki dressing. Toss gently so the potatoes stay mostly intact. Warm potatoes soak up flavor better than cold ones, which is why this recipe tastes so good after mixing. If you are making the salad for a crowd, this is the best time to fold everything together in a big serving bowl. If the salad seems a little thick, add a teaspoon of water or another small splash of lemon juice. If it seems too loose, let it rest for a few minutes and stir again. Different potatoes absorb dressing in different ways, so a little adjustment is normal.

4-Fourth step: Chill for the best flavor Cover the bowl and chill the salad for at least 30 minutes. One hour is even better if you have the time. During that rest, the dill, lemon, garlic, and cucumber blend into the potatoes and the flavor gets deeper and more balanced. If you are serving it later in the day, this is a great make-ahead window. If you are serving the salad at room temperature, let it sit out for 10 to 15 minutes after chilling so the yogurt dressing is not too firm. This gives you the best creamy texture and helps the flavors come forward.

5-Final step: Garnish and serve Right before serving, give the salad a gentle stir. Taste one more time and add more salt or pepper if needed. Sprinkle extra dill on top for a fresh finish. You can also add a few extra scallions if you want more color and bite. Serve this Tzatziki Potato Salad with grilled chicken, burgers, roasted vegetables, or sandwiches. It is also great with pita, hummus, and other Mediterranean-style dishes. The cool, tangy flavor makes it a nice contrast to rich main dishes.
