This is a straightforward potato salad โ waxy potatoes, fresh dill, and a mayo-mustard-lemon dressing โ that comes together in about 35 minutes. The dill and lemon keep it from feeling heavy, which makes it genuinely useful next to grilled meat or on its own on a warm day. Itโs the kind of thing you can pull off with one pot and one bowl.
The technique that matters
The most important step is letting the potatoes cool before you dress them. Hot potatoes absorb liquid fast, which sounds useful but actually means theyโll soak up the dressing unevenly and turn the mayo oily and broken. Spread them out on a cutting board after draining โ donโt pile them in a bowl โ so steam escapes quickly. Cut them once theyโre just cool enough to handle, not stone cold. Slightly warm potatoes still pick up seasoning well; fully cold ones donโt absorb much at all. The second thing worth getting right is the dressing itself: whisk the mustard into the mayo before adding the lemon juice. Mustard acts as an emulsifier here, so the dressing stays cohesive and actually clings to each piece instead of pooling at the bottom of the bowl.
Substitutions that actually work
- Potatoes: Stick with waxy varieties โ Yukon Gold, red-skinned, or fingerlings. Russets will fall apart and turn the dressing starchy and gluey.
- Fresh dill: Dried dill is a poor substitute here โ use about one teaspoon if youโre stuck, but the flavor is noticeably flatter. Fresh parsley works better as a true swap if dill isnโt available.
- Mayonnaise: The recipeโs note about Greek yogurt is solid. Full-fat yogurt keeps the dressing creamy; low-fat versions make it thin and slightly sour in a way that competes with the lemon.
- Dijon mustard: Whole-grain mustard works and adds a bit of texture. Yellow mustard is sharper and sweeter โ use half the amount if thatโs what you have.
Storage and make-ahead
Dress it at the table โ a pre-dressed salad goes limp fast. If youโre making this ahead, keep the cooked and cut potatoes in one container and the dressing in a separate jar, both refrigerated. The potatoes hold well for up to two days; the dressing keeps for three. Combine them 30 minutes before serving so the flavors have time to settle, as the recipe specifies. If the salad has already been dressed and youโre storing leftovers, it will keep in the fridge for up to two days โ the texture softens but the flavor is still good. Give it a stir before serving and add a small squeeze of fresh lemon to brighten it back up.
Mistakes to avoid
- Cutting the potatoes before boiling: Small pieces overcook quickly and crumble when you fold in the dressing. Boil them whole or halved, then cut after cooling.
- Under-seasoning the cooking water: The recipe calls for salted water, but it should taste noticeably salty โ like pasta water. Potatoes cooked in bland water taste flat no matter how well-seasoned the dressing is.
- Adding dill too early when the potatoes are still warm: Heat wilts fresh dill and dulls its flavor. Wait until the potatoes have cooled and the dressing is mixed in before folding the dill through.
- Over-folding: Once the dressing and dill are in, stop mixing. Repeated folding breaks the potato pieces down and makes the whole thing starchy and dense.
- Skipping the 30-minute chill: The salad tastes sharp and disjointed straight after mixing. The rest time lets the lemon and mustard mellow into the mayo and the potatoes absorb just enough dressing to taste cohesive.
Uruguayan Potato and Dill Salad
Ingredients
- 500 g potatoes Choose waxy potatoes for a firm texture after boiling
- 0.5 cup dill Fresh, chopped
- 0.5 cup mayonnaise Preferably homemade or a high-quality store brand

- 1 teaspoon salt Adjust to taste
- 0.5 teaspoon black pepper Freshly ground
Instructions
- Boil the potatoes in a large pot of salted water until they are just tender, about 15 minutes. When done, a fork should easily pierce the potatoes without breaking them apart.
- Drain the potatoes and allow them to cool before cutting them into bite-sized pieces, enhancing their ability to absorb dressing.
- In a mixing bowl, combine the mayonnaise, Dijon mustard, lemon juice, salt, and black pepper. Whisk until smooth and emulsified.
- Gently fold the potatoes into the dressing, ensuring each piece is well-coated. Add the chopped dill and continue to fold gently until well integrated.
- Refrigerate the salad for at least 30 minutes before serving to allow the flavors to harmonize.

FAQ
What kind of potatoes work best for this salad?
Waxy potatoes are the right choice โ varieties like Yukon Gold, red-skinned, or fingerlings hold their shape after boiling. Starchy potatoes like Russets absorb too much water, fall apart when you cut them, and make the dressing gluey.
Can I make this salad the night before?
Yes, but keep the potatoes and dressing separate until about 30 minutes before you plan to serve it. Dressed potato salad stored overnight turns soft and the dressing gets watery as the potatoes continue to release moisture.
The dressing looks thin or broken โ what went wrong?
This usually happens when the lemon juice is added to the mayo before the mustard is fully mixed in. Whisk the Dijon into the mayo first to build the emulsion, then add the lemon juice gradually. If itโs already broken, whisk in a small spoonful of fresh mayo to bring it back together.
How do I know when the potatoes are done without overcooking them?
Pierce a potato with a fork โ it should slide in with light resistance and come out cleanly without the potato cracking or splitting. If the potato slides off the fork on its own, itโs overcooked and will fall apart in the salad.
