Classic Potato Salad

Why This Classic Potato Salad Works

Starting the potatoes in cold, salted water lets them heat up slowly, so they cook evenly from the outside in. As they boil, the cubes soften all the way through without breaking apart too much. Yukon Golds are waxy, so they stay creamy and hold their shape instead of turning mushy. After draining, the short cooling time keeps them warm enough to soak in the dressing, but not so hot that the mayonnaise separates.

In the bowl, the mayonnaise, mustard, and vinegar coat each potato piece. While the salad chills, that dressing slowly sinks into the warm centers, so the potatoes don’t taste plain inside. The salt and pepper spread through the salad during this time too. Crunchy celery, red onion, and dill pickles stay firm because they are added after cooking, so there is a mix of soft and crisp in each bite. As the salad rests in the fridge, everything settles, the sharp edges from the onion and vinegar calm down, and the whole bowl tastes more even and smooth.

Mistakes To Avoid

Boiling the potatoes until they are falling apart turns them mushy. Once mixed with the dressing, they break down even more and the salad turns into a thick paste instead of having soft, distinct chunks.

Adding the potatoes while they are still hot causes the mayonnaise mixture to loosen and almost melt. The dressing turns greasy and runny, and the potatoes soak it up unevenly, so some bites are dry and others are heavy and slick.

Skipping the salt in the cooking water leaves the potatoes bland all the way through. Even with plenty of dressing on the outside, the centers stay flat and dull, so the salad tastes uneven from bite to bite.

Stirring the salad too hard or too often crushes the potato cubes and smashes the celery and pickles. The crunchy pieces lose their snap, and the whole bowl starts to look and feel like mashed potatoes with random bits in it.

Cutting the potatoes into very different sizes makes them cook unevenly. Small pieces turn soft and start to fall apart while the bigger chunks stay firm and slightly hard in the middle.
