Why You’ll Love This Classic Creamy Potato Salad
- One Pot Cooking: You only need one pan for the potatoes, meaning minimal washing up after a hectic day.
- Make-Ahead Magic: This salad tastes better after a few hours in the fridge, so you can prep it during nap time or while the kids do homework.
- Pantry-Friendly Ingredients: Most of what you need — potatoes, eggs, mayonnaise, and mustard — are staples you likely already have on hand.
- Naturally Crowd-Sized: It’s generous enough to feed a hungry family, with leftovers that pack perfectly for lunch the next day.
- No Oven Required: In the middle of a heatwave or when you’re just too tired to turn on the oven, this stovetop meal is a lifesaver.
Ingredients You’ll Need
- 1 kg (about 6 medium) waxy potatoes, such as Desiree or Charlotte
- 4 large free-range eggs
- 200 ml (about ¾ cup) full-fat mayonnaise
- 2 tablespoons wholegrain mustard
- 1 tablespoon white wine vinegar
- 4 spring onions, finely sliced (white and green parts)
- 2 celery sticks, finely diced
- 2 tablespoons fresh flat-leaf parsley, chopped
- ½ teaspoon sea salt, plus more for the cooking water
- ¼ teaspoon freshly ground black pepper
- 1 tablespoon capers, roughly chopped (optional, but I love the little bursts of brine)
Tip: Waxy potatoes are key here. Floury potatoes like Maris Piper will break apart and turn the salad into a gluey mash. You want a potato that holds its shape after boiling.
How to Make Classic Creamy Potato Salad
- Boil the potatoes (with a twist): Place the whole, unpeeled potatoes in a large pot and cover them with cold water by about 2 inches. Add a generous tablespoon of salt. Bring to a rolling boil over high heat — you’ll see large, vigorous bubbles breaking the surface. Reduce the heat to a steady simmer and cook for 15-20 minutes. You’ll know they’re ready when a knife slides into the centre with almost no resistance and the skins start to crack slightly. This method keeps the potatoes from absorbing too much water.
- Cook the eggs to perfection: While the potatoes boil, carefully lower the eggs into a separate small saucepan of boiling water. Set a timer for exactly 8 minutes for a just-set yolk that’s still creamy. When the timer goes off, immediately drain and plunge the eggs into a bowl of ice water. You’ll hear a satisfying hiss as the cold water hits the hot shells. Let them sit for 5 minutes, then tap the shells all over and peel under running cold water. The shells should slip off easily.
- Prepare the potatoes: Once the potatoes are tender, drain them in a colander and let them steam dry for a full 5 minutes. You’ll notice the steam rising off them — this is good; it means the excess moisture is evaporating. When they’re cool enough to handle but still warm, use a small knife to peel off the skins (they’ll come off in big, easy strips). Cut the potatoes into 2-3 cm chunks and spread them on a large baking tray to cool completely. The texture should be fluffy on the inside but firm on the outside.
- Make the dressing: In a small jar with a tight-fitting lid, combine the mayonnaise, wholegrain mustard, white wine vinegar, salt, and pepper. Screw the lid on tightly and shake vigorously for about 20 seconds. The dressing should look pale yellow, smooth, and emulsified, with a tangy, sharp aroma from the vinegar and mustard.
- Assemble the salad: In a large salad bowl, combine the cooled potatoes, sliced spring onions, diced celery, and chopped capers if using. Pour about half the dressing over the top and toss gently with salad servers until everything is evenly coated. You want every chunk of potato to have a thin, glossy sheen.
- Finish with the eggs: Roughly chop the peeled eggs into chunky pieces (not too small — you want to see distinct pieces of white and yolk). Gently fold them into the salad along with the remaining dressing. Taste a small spoonful — the potato should be creamy, the dressing tangy, and the eggs soft. Adjust the salt and pepper if needed.
- The crucial rest: Cover the bowl with cling film and pop it in the fridge for at least 30 minutes. This resting time lets the flavours meld together. When you take it out, give it a gentle stir. If the salad seems a little dry, stir in a tablespoon of milk or a splash of extra vinegar to revive the creaminess.
Tips From My Kitchen
- Don’t skip the steaming step: Letting the potatoes steam dry after draining is non-negotiable. If you dress hot, wet potatoes, the dressing becomes watery and thin. The steam evaporates the surface moisture, allowing the dressing to cling to the potato rather than sliding off. This is the single biggest factor in achieving a creamy, not watery, salad.
- Use a jar for the dressing: A jam jar with a lid is my secret weapon. It emulsifies the dressing perfectly in seconds, and you can store any leftover dressing right in the same jar. No whisk, no bowl, no mess. This is the kind of time-saving trick that makes a weeknight dinner feel effortless.
- Season the cooking water generously: The potatoes absorb the salted water as they cook, seasoning them from the inside out. If you only add salt to the dressing, the potatoes themselves will taste bland. The water should taste as salty as the sea — about a tablespoon per litre of water.
- Cool the potatoes completely before dressing: Warm potatoes will make the mayonnaise separate and become oily. I spread them on a baking tray to maximise surface area — they cool in about 10 minutes flat. You can even pop the tray in the fridge for 5 minutes if you’re in a real rush.
- Double the dressing for leftovers: Potato salad tends to dry out overnight as the potatoes absorb the dressing. If I’m making this for a busy week, I make an extra half-batch of dressing and store it separately. The next day, I just stir in a few spoonfuls to bring the salad back to life. It tastes as good as the first day.
Equipment You’ll Need
- Large salad bowl
- Sharp knife and cutting board
- Salad servers
- Small jar for dressing
- Large pot for boiling potatoes
- Small saucepan for eggs
- Baking tray for cooling potatoes
Common Mistakes to Avoid
- Overcrowding the pan: If you cram too many potatoes into one pot, they cook unevenly and some will turn to mush while others remain hard. Use a pot large enough that the potatoes sit in a single layer, or at most two layers. The water should circulate freely around each potato. This ensures a consistent, creamy texture throughout.
- Wrong temperature: Dressing warm potatoes is the fastest route to a greasy, separated mess. The heat from the potatoes causes the mayonnaise to break, leaving you with an oily film on top of the salad. Always let the potatoes cool to room temperature — around 20°C — before adding the dressing. If you’re in a hurry, spread them on a tray and pop them in the fridge for 10 minutes.
- Skipping the rest time: I know it’s tempting to serve immediately, especially when everyone is hungry, but resting is where the magic happens. The flavours need time to marry, and the potatoes need time to absorb some of the dressing. A 30-minute rest in the fridge transforms a good salad into a great one. The texture becomes more cohesive and the taste more rounded.
Delicious Variations to Try
- Spicy Version: For a kick of heat, stir in 1-2 teaspoons of harissa paste or a finely chopped red chilli into the dressing. The warmth balances beautifully with the creamy mayonnaise and cool potatoes.
- Vegetarian/Vegan Option: Swap the eggs for a 400g tin of chickpeas, drained and rinsed, and use a vegan mayonnaise. Add a tablespoon of nutritional yeast to the dressing for a subtle, cheesy flavour. The chickpeas add protein and a lovely nutty texture.
- Different Protein: Fold in 200g of shredded roast chicken or flaked tinned tuna for a more substantial main-course salad. Both work beautifully with the creamy dressing and soft potatoes. This is a great way to use up leftover Sunday roast chicken.
What to Serve With Classic Creamy Potato Salad
- A simple green salad with a lemon vinaigrette to cut through the richness
- Grilled chicken thighs or lamb chops for a heartier meal
- Crusty bread and butter to mop up any remaining dressing from the bowl

Frequently Asked Questions
Can I make this potato salad a day ahead?
Absolutely, and I actually recommend it. The flavours deepen and meld together beautifully overnight. Just be sure to keep the dressing slightly on the generous side, as the potatoes will absorb some of it. Before serving, give it a good stir and add a splash of milk or vinegar if it seems too dry.
How do I stop my potatoes from falling apart?
The key is using waxy potatoes and boiling them whole, with the skins on. Waxy potatoes have a lower starch content, so they hold their shape better. Boiling them whole also prevents the outside from overcooking while the inside finishes. If you absolutely must cut them first, cut them into large, 5cm chunks, not small cubes.
Can I use a different type of mustard?
Yes, you can easily swap the wholegrain mustard for Dijon or English mustard. Wholegrain gives a lovely texture and a milder, more complex flavour. Dijon will add a sharper, more pungent kick, while English mustard will bring a real heat. Just adjust the quantity to your taste — start with 1 tablespoon and add more if you like it punchy.
Is this recipe suitable for a picnic or barbecue?
It’s ideal for both. Because it’s served cold, you don’t need to worry about reheating. Just keep it in a cool bag or an insulated container if you’re heading out on a warm day. The dressing holds up well, and the salad won’t wilt or spoil quickly, making it a reliable choice for outdoor gatherings.
Can I add other vegetables to this salad?
Of course. Finely diced red pepper adds a lovely crunch and sweetness, while sweetcorn kernels bring a pop of colour and texture. I’ve also added blanched green beans, cut into short lengths, for extra freshness. Just be cautious with watery vegetables like cucumber — they can make the salad soggy if left to sit for too long.
