Tips for Sour Cream and Onion Potato Salad
A couple of things I’ve learned that make a difference:
- Use waxy potatoes like Yukon Gold or red potatoes to keep the salad from turning mushy.
- Don’t overcook the potatoes; you want them tender but still holding their shape.
- Finely chop the onions to avoid overpowering bites.
- Taste the dressing before mixing, and adjust seasoning gradually.

Leftovers and Storage
Potato salad doesn’t usually last long in my house, but if you have leftovers, here’s what you can do:
- Store in an airtight container in the fridge.
- Best eaten within 2-3 days.
- Give it a gentle stir before serving again; sometimes the dressing settles.
- Avoid freezing since potatoes can get mushy and the texture changes.

Common Mistakes to Avoid
Nobody’s perfect, and I’ve made my fair share of potato salad blunders. Here’s what to watch out for:
- Overcooking potatoes: Mushy potatoes ruin the texture.
- Too much onion: It can overpower the whole salad, so balance is key.
- Skipping the chill time: The flavors need time to blend.
- Using the wrong potatoes: Starchy potatoes like Russets can fall apart.
- Overmixing: Be gentle to keep the potato chunks intact.
