Method
Quick Pickle the Onions
1
Slice the yellow onion into thin half-moons. Place in a bowl with red wine vinegar, salt, and sugar. Toss well and let sit for at least 20 minutes, stirring occasionally. The onions will soften and turn vibrant pink.
Cook the Potatoes

3
Transfer drained potatoes to a baking sheet or large plate. Spread in a single layer and let steam dry for 5 minutes. This helps them hold their shape and absorb dressing better.
Make the Dressing and Assemble
4
In a large bowl, whisk together olive oil, red wine vinegar, salt, and black pepper until emulsified.
5
Add the warm potatoes to the dressing. Gently fold to coat without breaking the potatoes.
6
Strain the pickled onions, reserving the vibrant vinegar liquid. Add the pickled onions to the potatoes. Pour over a splash of the reserved pickle liquid for extra tang.

Safety & Storage
Storage
Refrigerate any leftover salad within 2 hours. Store in airtight container for up to 3-4 days. The vinegar-based dressing helps preserve the salad compared to mayonnaise-based versions.
Temperature
Do not leave potato salad at room temperature for more than 2 hours total. The 10-minute rest period before serving is safe, but extended time at warm temperatures creates food safety risk.
Handling
Use separate cutting boards for raw pickled onions and cooked potatoes to prevent cross-contamination. Ensure potatoes are fully cooled before refrigerating to avoid condensation and bacterial growth.
Allergen Warning
Although not one of the 14 major allergens, this recipe contains sulfites from red wine vinegar. Individuals with sulfite sensitivity should exercise caution.
High Risk Population
Immunocompromised individuals, pregnant women, and elderly should ensure all potato components are properly cooked and promptly refrigerated. The vinegar acidity provides some protection but does not guarantee safety for high-risk populations if mishandled.
Pro Tips
Technique
Let your drained potatoes steam dry in a single layer for five minutes before dressing. Dry potatoes grip the vinaigrette instead of sliding away, and they keep their shape when you fold them gently.
Substitution
No red wine vinegar? Apple cider vinegar or white wine vinegar both work—the pink color won't be as dramatic, but the tang and the resurrection effect will absolutely be there.
Flavor Boost
That vibrant pink vinegar from your pickled onions is liquid gold. Don't discard it. A splash stirred in at the end makes this salad taste like it was planned, not assembled from scraps.
From the chef
Let me be direct with you—if your potatoes are sitting in the fridge looking sorry for themselves, they just need a proper intervention. This is what I call resurrection with a capital R: quick-pickled onions transform from sharp and raw into something that pops against that buttery potato flesh, and a splash of their magenta vinegar brings everything back from the dead. Nobody at my table has ever called this 'leftovers.' They call it the good salad that disappeared too fast.
