Make Creamy Potato Salad Recipe: tender russets, creamy dressing, and crisp veggies — perfect for picnics and weeknight dinners.
Place the unpeeled whole russet potatoes into a pot, cover with water and bring up to a rolling boil, adding about 1/2 tablespoon salt. Maintain a steady medium boil and cook for roughly 20–30 minutes until each potato is easily pierced with a fork but not falling apart; the texture should be tender through but still holding shape. Drain, let cool completely to room temperature (this helps the dressing cling later), then peel and dice into roughly 1/2–3/4 inch cubes just before assembling. Potatoes can be cooked 1–2 days ahead, cooled, covered and refrigerated.
In a small bowl, stir together the mayonnaise, sour cream and yellow mustard with 1/2 teaspoon salt (reserve a little to adjust later). Whisk to a smooth, velvety consistency so it will coat but not be soupy; refrigerate the dressing until the salad is ready to be dressed. This is a gentle, forgiving mix — you can tweak salt, mustard or tang when you taste the tossed salad.

In a large white ceramic mixing bowl combine the diced cooled potatoes, half-cup diced English cucumber, thinly sliced radishes, finely diced celery, and the chopped hard-boiled eggs and chives. Spoon in most of the chilled dressing and fold gently with a wooden spoon so chunks remain intact and the creamy dressing evenly clings to pieces; add more dressing to taste until the salad looks luxuriously coated but still textured.
Taste and finish with an extra pinch of salt and a generous crack of black pepper (I like about an additional 1/4 tsp salt and 1/4 tsp cracked pepper). Transfer to the same large white serving bowl if desired, garnish with extra chopped chives and a scattering of freshly cracked black pepper. Serve at room temperature or slightly chilled; leftovers keep well refrigerated.
