Method
Boil and cool the potatoes
- Bring a pot of water to a boil, then cook the russet potatoes until tender, about 15–20 minutes. Visual cue: the cubes should yield easily when pierced with a fork.
- Drain the potatoes and let them cool until room temperature, about 5–10 minutes. Visual cue: steam should stop rising and the surface should look dry.
Make the potato mixture
- In a mixing bowl, combine the cooled russet potatoes with the hard-boiled eggs, celery, onion, and sweet pickle relish. Visual cue: the ingredients should be evenly distributed through the potatoes.
Mix the rich dressing
- Whisk together mayonnaise, sour cream, yellow mustard, white vinegar, sugar, salt, and pepper until smooth and creamy. Visual cue: the dressing should look uniform with no mustard streaks.
Combine and chill
- Pour the dressing over the potato mixture and fold gently until very creamy, about 2–3 minutes. Visual cue: the salad should take on a thick, glossy white coating.
- Refrigerate the creamy potato salad for at least 2 hours before serving. Visual cue: it should look set and extra thick, with dressing clinging to the potatoes.
Notes
Pro tip: cool the potatoes to room temperature before mixing so the dressing stays thick and doesn’t loosen. Refrigerate in a covered container for up to 4 days; freeze is not recommended because mayonnaise-based salads can separate after thawing. For a lighter version, use light mayonnaise (and keep sour cream) to reduce fat while maintaining the creamy texture.
