This vibrant potato salad with soft-boiled eggs is a sophisticated twist on a classic vegetarian side dish. By steaming the new potatoes rather than boiling them, they retain a firmer texture and a naturally sweet flavour that pairs beautifully with the acidity of the cider vinegar. The addition of toasted mustard seeds and chopped dill pickles provides a satisfying crunch and a sharp, savoury contrast to the creamy yolks of the jammy eggs.
Perfect for a weekend lunch or as a standout addition to a summer spread, this homemade salad is both filling and nutritious. The mustard vinaigrette can be prepared up to three days in advance, making it an easy option for busy hosts. Serve it at room temperature to allow the herb-infused flavours of the parsley and chives to shine.

1 teaspoon mustard seeds
45ml apple cider vinegar

How to make Potato Salad with 7-Minute Eggs and Mustard Vinaigrette
Back to contentsSteam potatoes, covered, in a metal steamer basket set in a large pot over boiling water until tender, 20–30 minutes, depending on size. Transfer to a plate and let cool.
Meanwhile, cook eggs in a large saucepan of boiling water until whites are set and yolks are still slightly soft, 7 minutes. Drain; transfer eggs to a bowl of ice water and chill until cold. Drain and peel; set eggs aside.
Toast mustard seeds in a dry small skillet over medium-low heat, tossing constantly, until seeds start to pop, about 1 minute. Transfer to a small bowl (be ready with bowl; once seeds get going, it's chaos).
Whisk vinegar, mustard, and honey in a large bowl. Whisking constantly, gradually add oil; whisk until emulsified. Season with salt and pepper. Set 45ml vinaigrette aside for drizzling.
Halve potatoes and add to bowl with vinaigrette. Add parsley and toss to coat; season with salt and pepper. Transfer to a platter. Halve reserved eggs and tuck in between potatoes. Drizzle with reserved vinaigrette. Top with pickles, chives, and toasted mustard seeds.
Eggs can be boiled 1 day ahead; drain, cover, and chill. Peel just before using. Vinaigrette can be made 3 days ahead; cover and chill.
