This timeless classic potato salad strikes the perfect balance between creamy and tangy. Tender red potatoes are gently tossed with a light, flavorful dressing made from Greek yogurt and mayonnaise, offering richness without being too heavy. Thinly sliced red onion adds a crisp bite, while briny capers bring a pop of bold, savory flavor. Simple, fresh, and satisfying—this is a go-to side dish for picnics, barbecues, or any casual gathering.
Peel the potatoes and cut them into 2.5-by-2.5-centimeter cubes (1 inch x 1 inch). Place them in salted cold water and bring to a boil. Cook for about 15 minutes until al dente. Drain and leave to cool on a plate or cutting board.
Cut the red onion into thin rings. Place the red wine vinegar in a small bowl and marinate the onion rings in it for 15 minutes.
In a small bowl, mix the mustard, yogurt, and mayonnaise, then stir in the finely chopped parsley.
Toss the potatoes in the dressing, then mix in the capers. Season to taste with additional salt and pepper.
