Boil and cool the potatoes
- Add cubed red potatoes to a Dutch oven and cover with water; bring to a boil over high heat, then continue until tender, about 10-15 minutes. You’ll know they’re ready when a knife slides in easily and the pieces start to look slightly fluffy at the edges.
- Drain the potatoes and spread them on a sheet pan to cool for a few minutes before mixing. The surface should be dry to the touch, not steaming.
Build the potato salad
- Add cooled potatoes, cooked crumbled bacon, and about half of the blue cheese to a large bowl and toss to distribute evenly. The potatoes should look evenly speckled with bacon and blue cheese.
- Whisk sour cream, mayonnaise, buttermilk, white wine vinegar, salt, and pepper until smooth and pourable, about 30-60 seconds. Stop when the dressing looks creamy with no streaks.
- Pour the dressing over the potato mixture and toss gently until the potatoes are coated. The salad should look glossy, with dressing clinging to the potato surfaces.
- Top with the remaining blue cheese and the sliced green onions. Finish with a visible scatter of blue cheese crumbles on top.
Chill and serve
- Refrigerate the potato salad for 2 hours before serving. It should be cold throughout and hold together when you scoop it.
Notes
Pro tip: let the potatoes cool briefly before dressing so the mayonnaise doesn’t thin out. Refrigerate covered for 3-4 days; the flavors improve after the first hour. Freezing: no, the creamy dressing can break after thawing. If you prefer a lighter option, use plain Greek yogurt in place of half the mayonnaise.
