Cook and prep the potatoes
- Bring a pot of water to a boil, then add the small Yukon gold potatoes and boil until tender, about 20 minutes, with a visible simmer. When a knife slips in easily, turn off the heat and proceed.
- Drain the potatoes and let them cool slightly, about 5 minutes, so they’re warm but not hot. Cut them into quarters and keep them ready for mixing.
Make the dressing
- Whisk mayonnaise, white wine vinegar, Dijon mustard, olive oil, kosher salt, and black pepper in a bowl until smooth and glossy. Keep whisking until no mustard streaks remain.
Assemble and chill
- Combine the warm potatoes, celery, and red onion in a bowl so the vegetables start to soften slightly. Toss gently to distribute the mix.
- Pour the dressing over the potatoes and toss gently until every piece is lightly coated. Stop when the sheen is even, without smashing the potatoes.
- Add dill and parsley, then toss again just until the herbs are evenly dispersed. The mixture should look speckled with green throughout.
- Refrigerate for at least 2 hours before serving, covered, to let flavors meld and the dressing set slightly. Serve cold from the fridge.
Notes
Pro tip: toss the dressing with warm (not steaming) potatoes so the vinaigrette-mayo clings without turning gummy. Refrigerate leftovers in a sealed container up to 4 days; freeze is not recommended due to texture changes. For a lighter option, use light mayonnaise in the same amount for a reduced-calorie dressing.
