Make it in advance
If you are making it the same day, allow at least 2 hours to chill to allow the flavours to come together. In fact, our homemade potato salad tastes even better if made the day before so the flavours have a chance to really come together.
Preparing it in advance also makes it ideal for picnics or lunch-boxes.
Your questions answered
Waxy potatoes are the best potatoes for potato salad. As they are low in starch and high in moisture they will retain their shape well after boiling. Potatoes that are too starchy (floury) will become mushy and fall apart easily.
👩🏻🍳 Helpful tips
- Select the right kind of potato, waxy varieties work best.
- Place the potatoes into a pan of salted cold water. Adding them to boiling water will make them cook quickly on the outside while remaining raw inside.
- A splash of vinegar added to the cold water prevents the potatoes from overcooking and becoming too soft.
- After the potatoes have cooled, toss them gently with chopped celery, gherkins, onion and dressing.
- Cover and chill for at least two hours, the longer it rests, the tastier it will be.
- Before serving, garnish with sliced hard boiled eggs for extra creaminess and parsley.
Substitutions
- Run out of gherkins? You can use pickled jalapeños and their pickling water.
- Don’t have sour cream? Increase the mayonnaise to ¾ cup and add 1 Tablespoon lemon juice.
- No red onions? Use a white onion sliced finely. In a small bowl mix together 1 tablespoon white wine vinegar, 1 teaspoon sugar and ½ cup cool water. Add the sliced onion ensuring it is completely submerged (if not, add a little more water) and set aside for 20 minutes. Drain the liquid away before using the onions.
❄️ Storing
Cover and keep in the fridge for up to 4 days. This potato salad is not suitable for freezing.

Notes
- This dish is best made the day before for the flavours to fully come together.
- Select the right kind of potato. Waxy potatoes work best as they are low in starch and high in moisture, so they retain their shape well after boiling. If the potatoes are too starchy (floury), they become mushy and fall apart.
- The potatoes should be added to salted cold water rather than boiling, otherwise they will cook too quickly on the outside, while remaining raw inside.
- The potatoes are boiled in plenty of salted water, with a splash of vinegar to prevent them from overcooking and becoming mushy.
- After cooling, add the dressing and gently mix, ensuring the potatoes are evenly coated in dressing.
- Garnish with sliced hard boiled eggs for extra creaminess and parsley.
- Cover and chill for at least two hours, the longer it rests, the tastier it will be.
- Potato salad will keep covered in the fridge for up to 4 days. It is not suitable for freezing.
- Run out of gherkins? You can use pickled jalapeños and their pickling water.
- Don’t have sour cream? Increase the mayonnaise to ¾ cup and add 1 tablespoon lemon juice.

I had no clue that the vinegar was so crucial in helping with the cooking process, I will have to do this next time as I hate a mushy potato salad! Can’t wait to try this one out.

I’m going to have to try vinegar in potatoes, that sounds like a great trick, plus I always love a little twang to my potato salad!

I agree, potato salad is always better the next day. I always make it the day before I need it. Perfect for the warmer weather coming….not soon enough. Great for grilling season.

One time at work, a friend made potato salad for potluck and she added heaps of jalapenos in it and it was delicious.

I’m not sure I’ve ever made a potato salad. Thanks for tips on adding cider vinegar, I would never have known to do that. 🙂
