Cook Potatoes: Boil baby potatoes until tender. Preheat oven or air fryer to 190°C (375°F).
Roast: Place boiled potatoes on a baking tray. Smash gently, drizzle with olive oil, salt, and pepper. Roast for 30-40 minutes (oven) or air fry for 20 minutes until crispy.
Dressing: Mix yogurt, mayo, garlic, herbs, salt, and pepper. Stir in cucumber and red onion.
Combine: Once the potatoes cool, add them to the dressing and toss to coat.
