This smashed potato salad combines oven-crisped baby potatoes with a tangy Greek-yogurt and kewpie mayo dressing, fresh herbs, cucumber and shallot for a crunchy, creamy side dish that’s perfect warm or chilled.
Preheat the oven to 425°F and line a large baking sheet with parchment paper.
Place the scrubbed baby potatoes in a pot of boiling water and cook until a fork easily pierces them, about 7 minutes. Drain and pat dry.
Arrange the potatoes on the prepared sheet and gently flatten each one with the bottom of a glass until smashed. Brush the tops with olive oil and season with salt and pepper.
Roast the smashed potatoes for roughly 50 minutes to 1 hour, or until they develop a golden, crisp exterior. Reserve any extra crunchy browned pieces for garnish.
Salad:
Trim and remove the seeds from the cucumber to prevent excess moisture, then finely chop it.
In a bowl, whisk together Greek yogurt, kewpie mayo, Dijon, lemon juice, red wine vinegar, minced garlic, chopped dill, chopped parsley, and salt and pepper. Taste and adjust seasoning as needed.
Fold the chopped cucumber and shallot into the dressing mixture, then cover and chill while the potatoes finish roasting.
Assembly:
Let the roasted potatoes cool for about 5 minutes, then gently combine them with the chilled dressing and vegetables so each piece is well coated.
Top with reserved crispy potato bits, extra dill and a grind of black pepper. Store leftovers refrigerated.
