Deliciously creamy and totally moreish this Potato Salad with Spring Onions is my go-to recipe for potato salad. It's a tried and tested recipe that I've been making for years and everyone loves it!
The perfect summer side dish, this potato salad is a big deal in my house. I make it for every BBQ we have and any summer family get-togethers.
This spring onion potato salad is one of the easiest ways to make potato salad but it doesn't skimp on taste! It's perfectly creamy, tangy and delicious.
Why You'll Love This Recipe
- It's so creamy! - we love our potato salad to be properly creamy and this one is exactly that!
- So easy to make - this really is the easiest recipe for potato salad! No messing around with peeling or mashing!
- Just a few simple ingredients - made with under 10 ingredients, all store cupboard ingredients too!
- Potatoes - you will need small waxy potatoes for this recipe. New potatoes, Charlottes, Jersey Royals or Red Bliss, or fingerlings if you are in the US will all work well.
- Spring Onions - or scallions in the US. I use 5 or 6 spring onions for this.
- Mayonnaise - I use a full-fat mayo for this potato salad. You can use a low-fat mayo if you like.
- Mustard - Dijon mustard is my preference for this recipe as it has a tangy flavour which works well with the mayo.
- Cornichons - these add some crunch and sourness to the potato salad, they also hold up well in that creamy sauce and won't lose their crunch.
- Herbs - you will need flat-leaf parsley and chives, chive flowers are optional!
How To Make Potato Salad with Spring Onions
Firstly, Cook the potatoes - add the potatoes to a saucepan and fill it with cold water add a generous pinch of salt. Drain the potatoes and put the pan back on low heat to remove any leftover water.
Add the mayo and mustard - gently toss the potatoes in the mayo and mustard.
Add the spring onions and cornichons - chop the spring onions and cornichons, add them to the potatoes and stir them through the potatoes.
Finally, add the herbs - chop the parsley and chives, add them to the potatoes, season with sea salt and freshly ground black pepper, and toss gently one last time.
- Make sure your potatoes are roughly the same size, I cut mine in half and if any are bigger I will cut them into quarters. This will ensure they are all cooked at the same time.
- Once you drain the potatoes, pop them back on low heat to dry them out a bit, this will get rid of any excess water.
- Add the mayo to the potatoes when they are warm, this will help the mayo to stick to the potatoes. If you add the mayo when the potatoes are completely cold the mayo will just slip off the potatoes.
- I always leave the skin on my potatoes, I like the added texture. You can peel them if you want though. I would peel them after they are cooked and use a tea towel to avoid the burn!
There isn't a lot of starch in those small waxy potatoes so I don't rinse them. I would only rinse them if you wanted to cool them down to peel them.
I love this potato salad warm, but you can enjoy it at room temperature or cold from the fridge.
Potato salad will last from 1 - 2 hours max sitting out. It will last for about 3 days in the fridge though.
Storage and Making Ahead Tips
This potato salad can be made up to 3 days in advance. I would make it according to the recipe but add the herbs a few hours before you serve it.
Store the potato salad in an airtight container in the fridge. Any leftovers that have been sitting out for under 2 hours can be refrigerated and should be used up within 2 days. To be honest this potato salad never lasts that long as it's usually demolished pretty quickly!
- Add-ins - You can add in some extras to this if you like, chopped boiled eggs would be great. Some chopped celery, avocado or sliced radish is good too.
- Make it vegan - I have made this using vegan mayo and it worked a treat, just make sure your Dijon mustard is vegan.
- Next level - make this next level by adding some nuggets of blue cheese! So good!
