Does This Potato Salad Need to Be Refrigerated?
Yes. It contains eggs and mayonnaise. When serving outdoors or for long periods or if will be out for an extended amount of time, use a larger bowl with ice water underneath it to keep it cool.
Best Potatoes To Use
We have always used russet potatoes. They are on sale often, easy to grow and delicious. They do fall apart a bit, but that doesn’t change the taste. If you want a firmer potato, you can use yukon gold potatoes or red potatoes for a firmer potato salad.


What Goes into Homemade Potato Salad?
- diced cooked boiled potatoes
- chopped hard boiled eggs
- diced onion (we use sweet)
- finely chopped celery
- yellow mustard & mayonnaise
- sugar

Can You Use Miracle Whip to Make this Potato Salad?
You can, but it will change the taste of it. And it’s not how my grandma made it. She used mayonnaise. If your tastes are more for Miracle Whip, then try it and see if you like it.

Can Baked Potatoes Be Used Instead of Boiled Potatoes?
Definitely. You may find that you need to add additional liquid to the potato salad (more mayonnaise and mustard, if the potatoes were dry.
Do You Add Sweet Relish or Pickles?
Not in this recipe, but if you want to, knock yourself out!
Storage and Serving
The potato salad should be kept chilled at your gatherings. Using a larger bowl with ice and your potato salad bowl on top works well. You should not leave the potato salad out for more than 2 hours. Potato salad lasts in the fridge 3-4 days.
Variations
- Use red or Yukon Gold potatoes: for firmer texture
- Add sweet relish: if you prefer tang
- Try baked potatoes: for a shortcut
Tips for Perfect Old‑Fashioned Potato Salad
- Don’t overcook the potatoes: they should be tender but not falling apart
