Baby Potato Salad

This baby potato salad is a sophisticated take on a classic vegetarian side dish, using tender Yukon Gold or red-skinned potatoes for a buttery texture. Unlike shop-bought versions, this recipe features a luxurious, homemade mayonnaise flavoured with spicy brown mustard, providing a sharp contrast to the earthy sweetness of the new potatoes. The addition of fresh chives brings a pop of colour and a mild onion bite that elevates the entire dish.

Perfect for summer barbecues, garden parties, or a simple midweek lunch, this versatile salad is best served while the potatoes are still slightly warm to allow the dressing to absorb. It is a brilliant make-ahead option for busy hosts, as the mayonnaise can be prepared a day in advance. Serve it alongside grilled vegetables or as part of a traditional British picnic spread.

Ingredients for Baby Potato Salad

  • 900g baby Yukon Gold or red-skinned potatoes (about 36), unpeeled

  • Kosher salt

  • 1 large egg yolk

  • 2 teaspoons white wine vinegar

  • 120ml vegetable oil

  • 2 tablespoons spicy brown mustard

  • 2 tablespoons chopped fresh chives

Place potatoes in a large pot and add cold water to cover by 2"; season generously with salt. Bring to a boil, reduce heat, and simmer gently until potatoes are tender, 20-25 minutes. Drain and let potatoes cool slightly. Peel, if desired.

Meanwhile, whisk egg yolk and vinegar in a large bowl; season with salt. Whisking constantly, gradually add oil, drop by drop at first, and whisk until mayonnaise is thick and creamy. Whisk in mustard.

Add warm potatoes to bowl with mayonnaise and toss to coat; season with salt. Fold in chives just before serving.

DO AHEAD: Mayonnaise can be made 1 day ahead. Cover and chill.
