Potato salad is something I always associate with summer. In the winter I like my potatoes warm. But when the temperature goes up again after the winter I get all obsessed with all sorts of salads. Potato salads are no exception. I just love a creamy mayo-based salad made with potato chunks and some more yumminess. And the reason why I love potato salads so much might be in the fact that I love mayo. Homemade mayo is an absolute favourite. And it’s also so easy to make. This spring onion potato salad has lots of wonderful flavours all perfectly blended with homemade cilantro mayo.
Spring onion potato salad recipe
Potatoes take about a half hour to cook, but cooking time may vary according to potato size. In order to whip up this spring onion potato salad faster, I recommend cooking the potatoes the day before, and just leaving them in the fridge overnight. This allows to skip the cooking part as well as the cooling time. I recommend boiling the potatoes with the skin on and only peel them when cooked. I also prefer to cook the potatoes whole, as they retain their shape better.
Peeled and diced baked potatoes can be sprinkled with some lime juice before adding the other ingredients to the salad. This will give a little more flavour to your potatoes. Red onion gets also soaked in ice water and lime juice. This procedure washes away some of the strong onion juice, as well as seasoning it with some lime flavour. I personally love onion soaked in lime, it’s something I also do when making guacamole.

Making potato salad is very easy: just combine the potatoes, red onion and spring onions in a bowl and stir in the mayo dressing. In this spring onion potato salad I’m using homemade cilantro mayo. Making homemade mayonnaise is so satisfying, as it’s a pretty basic sauce that requires only 4 ingredients. Well, only 2 really – egg and oil – as the other 2 are condiments (salt and lemon juice). But if you don’t have a blender or don’t feel like making your own mayo, it’s okay to use store-bought mayonnaise. Just look for the one that is most natural and has the shortest ingredient list.
Freshly minced cilantro gives this spring onion potato salad a lot of flavour that really pairs well with the lime tones that come with every red onion bite. If you are one of those people who gets a soapy taste from cilantro, you can as well swap it for some fresh parsley. Adding herbs to the mayo really lifts this condiment to another level so this is not something I would recommend skipping. Then add creme fraiche, more lemon juice and some mustard and just stir to combine. Want to make it dairy free? Just take 2 more tablespoons of mayo instead of the creme fraiche.
Once the potatoes have been cut and the red onion has been soaked and drained, it’s just a matter of cutting up the spring onions. I prefer to only use the green part in this spring onion potato salad, and I generally leave some aside and only add it at the end as decoration. Combine the three veggies and dress with the cilantro mayo. Decorate with more minced cilantro (or parsley) and spring onions. Add a generous sprinkle of freshly cracked black pepper just before serving and enjoy with some grilled meat or veggies.
Spring may have arrived in Sweden, but the thermometer is still showing single digits. Still, grilling season is hopefully not too far away in time. If where you live BBQ season is also still not round the corner, you may want to pin this spring onion potato salad recipe for later.

- 700 g potatoes
- 1/2 red onion
- 4 spring onions (scallions)
- 100 g mayonnaise
- 1/2 tsp grainy mustard
- 3 tbsp minced cilantro (about 20 stalks)
- 65 g creme fraiche
- 1 tsp lemon juice
- 1 lime (juiced)
- freshly cracked black pepper
To make homemade mayonnaise
- 1 egg (room temperature)
- 200 ml vegetable oil
- 1/4 tsp salt
- 1 tsp lemon juice
The potatoes need to be boiled in salted water until tender and cooled completely to room temperature. To make this recipe faster, cook the potatoes the day before. Peel and dice the potatoes into bits of similar sizes.
Finely dice the red onion and place in a small bowl. Add ice cold water to completely cover the onion and add the juice of half a lime. Let soak for 10 minutes.
If making homemade mayonnaise: Crack the egg in a tall container and blend with a hand blender making up and down motions until the egg is beaten to fluffy (about a half minute). Always blending and keeping the same motion, pour the oil in a slow continuous stream. The mixture will soon emulsify and thicken, add all the oil until the end. Stop the mixer, add the salt and lemon, ang give a final buzz to combine.
In a bowl combine the mayonnaise, grainy mustard, creme fraiche, minced cilantro and 1 tsp lemon juice and stir to combine.
Place the potatoes in a bowl and add a splash of lime juice to them. Cut the green parts of the spring onions and add them to the potatoes. Drain the red onion and add that to the mixture. Add cilantro mayonnaise sauce to vegetables and stir to nicely distribute all over.
Garnish with extra spring onions and freshly cracked black pepper.
If not a big cilantro (fresh coriander) fan, swap with parsley.
