1-First Step: Prep the vegetables and dressing Start by washing the potatoes well. If your Yukon gold or red potatoes are small, cut them in half or quarters so they cook evenly. Set a large pot of water on the stove, add the 1 tablespoon plus 1 teaspoon kosher salt, and bring it to a boil. While the water heats, prepare the cucumber. Finely grate or very finely chop the 1/2 medium English cucumber, then squeeze out as much water as you can using a clean kitchen towel or several layers of paper towels. This step matters because excess water can make the salad loose instead of creamy. In a medium bowl, mix the Greek yogurt, scallions, dill, lemon juice, olive oil, grated garlic, black pepper, and the cucumber. Stir until smooth and taste it. Add a pinch more salt if needed. This dressing is the heart of the salad, so make sure it tastes bright and balanced.

2-Second Step: Cook the potatoes until just tender Once the water is boiling, carefully add the potatoes. Keep the heat at a steady boil, then lower it slightly if needed so the potatoes cook evenly. Depending on size, they should take about 10 to 12 minutes. You want them fork-tender, not falling apart. To check for doneness, pierce one piece with a fork or the tip of a paring knife. It should slide in easily with only a little resistance. If the potatoes are overcooked, they can break apart when mixed with the dressing, which makes the salad look mashed instead of chunky and fresh. For best texture, avoid salting the water too lightly. The potatoes absorb flavor as they cook, so that seasoned water helps build the final taste of the Tzatziki Potato Salad.

3-Third Step: Drain and cool the potatoes Drain the potatoes well in a colander, then let them sit for a few minutes so the steam can escape. If you have time, spread them out on a baking sheet for faster cooling. You do not want them piping hot when they hit the yogurt dressing, but they should still be warm. Warm potatoes absorb the dressing better than fully cold ones, which means more flavor in every bite. That said, if you are cooking ahead for a party, you can cool them completely and still get great results. Just make sure the dressing is well mixed before combining everything. If you are making this for meal prep or taking it to a potluck, this is also a good time to check seasoning. A small pinch of salt or pepper now can make a big difference later.

4-Fourth Step: Combine the salad gently Place the drained potatoes in a large mixing bowl. Pour the tzatziki dressing over the top and fold everything together gently with a spatula or large spoon. Try not to stir too hard. The goal is to coat the potatoes without smashing them. As you mix, you will see the dressing cling to the warm potatoes and turn glossy and creamy. If the salad looks a little thick, add a teaspoon of olive oil or a tiny spoonful of yogurt. If it seems too loose, chill it for a few minutes and it will firm up. Taste the salad again after mixing. Add more salt and black pepper as needed. Because potatoes can absorb a lot of seasoning, a final taste test is always worth it.

5-Final Step: Chill, garnish, and serve Cover the bowl and chill the Tzatziki Potato Salad for at least 1 hour before serving. This resting time lets the cucumber, dill, lemon, and garlic flavor settle into the potatoes. It is one of those dishes that tastes even better after a little time in the fridge. Right before serving, give the salad one more gentle stir. Garnish with extra dill and a few sliced scallions if you like. Serve it cold or lightly cool, depending on your preference. This recipe serves 6 to 8 people and works beautifully for summer cookouts, picnics, and easy family dinners. It also pairs nicely with Mediterranean mains like grilled chicken, falafel, or even a simple sandwich spread.
