NY Deli Potato Salad Recipe: Creamy and Tangy

New York deli potato salad is a chilled, creamy salad of tender potatoes tossed with mayonnaise, mustard, vinegar, celery, onion, and pickle relish. Deli counters and home cooks vary the details, but this version balances a soft, lightly tangy dressing with enough crunchy vegetables to keep every bite lively.

Ingredients

3 lb (1.36 kg) russet potatoes, peeled and cut into 1½-inch (4 cm) chunks
3 qt (2.8 L) cold water, or enough to cover the potatoes by about 1 inch (2.5 cm)
1 tbsp (15 g) kosher salt for the cooking water
2 large eggs (about 100 g without shells), for the optional-but-classic egg addition
2 tbsp (30 ml) distilled white vinegar, divided
1 cup (240 ml) mayonnaise
1 tbsp (15 ml) yellow mustard
1 tbsp (12 g) granulated sugar
1 tsp (6 g) fine salt, plus more to taste
½ tsp (1 g) celery seed
¼ tsp (0.5 g) freshly ground black pepper
1 cup (100 g) finely diced celery, about 2 to 3 ribs
½ cup (75 g) finely diced yellow onion
⅓ cup (80 g) sweet pickle relish, drained lightly
¼ tsp (0.5 g) paprika, for garnish (optional)

Instructions

Prepare the potatoes. Peel the potatoes and cut them into fairly even 1½-inch (4 cm) chunks so they finish cooking at about the same time. Put them in a large pot and add cold water to cover by about an inch. Stir in the kosher salt. Starting the potatoes in cold water helps the centers cook before the outside turns overly soft.
Cook the potatoes and eggs. Bring the pot to a boil over high heat, then lower the heat to maintain a gentle simmer. Cook the potatoes for 15 to 20 minutes, checking after 15 minutes with a thin knife or fork. They should be tender through the center but still hold their shape. Meanwhile, put the eggs in a small saucepan, cover with water, and bring to a boil. Cover the pan, turn off the heat, and leave the eggs in the hot water for 10 to 12 minutes; then transfer them to cold water. For whole boiled eggs, cook until both the yolk and white are firm. Peel and chop them once cool.
Drain and cool briefly. Drain the potatoes well and return them to the warm pot for about 30 seconds, shaking the pot gently to let excess moisture evaporate. Spread them on a rimmed tray or in a wide bowl and leave them to cool for 15 minutes. While they are still warm, sprinkle over 1 tablespoon (15 ml) of the vinegar and turn the chunks gently to distribute it. This lets the potatoes take on a little tang before the creamy dressing goes on.
Mix the dressing. In a large bowl, whisk together the mayonnaise, yellow mustard, sugar, fine salt, celery seed, black pepper, and remaining 1 tablespoon (15 ml) vinegar. Taste a small dab and adjust the salt if needed. The dressing should taste a little more assertive than you want the finished salad to taste, because the potatoes will mellow it.
Fold everything together. Add the warm potatoes, celery, onion, and relish to the bowl. Fold with a flexible spatula until the potatoes are coated, taking care not to mash them. Fold in the chopped eggs last so they remain in distinct pieces. If the salad looks slightly loose, do not add extra mayonnaise immediately; it will thicken as it chills.
Chill and finish. Cover and refrigerate for at least 2 hours before serving. This chilling time lets the dressing settle into the potatoes and gives the onion and celery seed time to flavor the salad. Before serving, fold it once more, taste, and add a pinch of salt or a teaspoon of vinegar if it needs more lift. Sprinkle with paprika if desired.

Tips

Choose the potato texture you like. Russets are a good choice for a soft, familiar deli-style salad: their edges become slightly fluffy and catch the dressing. Yukon Gold potatoes make a firmer, buttery salad and are less likely to crumble, so they are an easy substitute in the same quantity. Red potatoes hold their shape well too, though their skins are usually left on and the result feels less like the peeled-potato version here.

Keep the pieces even and watch the simmer. Potato chunks that vary greatly in size cook unevenly, and a hard rolling boil can break their edges before the centers are tender. Start checking early; a knife should slide into a chunk without resistance, but the chunk should still lift out intact. If a few pieces crack, fold gently rather than stirring vigorously.

Balance the dressing before adding more. Warm potatoes absorb flavor, while a cold salad tastes less salty and less sharp than a warm one. The vinegar tossed with the warm potatoes provides tang without requiring a heavy dressing. Chill first, then make final adjustments; adding a large amount of mayonnaise or salt before chilling can leave the finished salad bland or overly rich.

Adjust the onion if you prefer a milder bite. Finely diced yellow onion gives the salad a traditional savory edge. For a gentler flavor, use the same amount of thinly sliced scallion whites and greens, or soak the diced onion in cold water for 10 minutes and drain it well. The soak softens the sharpness without changing the rest of the recipe.

Serving Suggestions

Serve the salad cold or cool, straight from the refrigerator, with grilled or roasted foods, sandwiches, or a deli-style lunch spread. It pairs naturally with grilled chicken, burgers, hot dogs, sausages, and simple baked fish, and it works alongside coleslaw, sliced tomatoes, or a crisp green salad. For a picnic or buffet, spoon it into a chilled serving bowl and set that bowl over ice if it will be out for a while.

As a side dish, plan on about ½ cup (roughly 120 g) per person when there are several other sides. For a lunch plate or potluck where the potato salad is one of the main sides, allow closer to ¾ cup (about 180 g) per person. A sprinkle of paprika adds color, while a few extra pieces of finely diced celery on top give guests a hint of the crunchy texture inside. Keep a clean serving spoon with the bowl so people do not transfer food from their plates back into it.

Variations

Make it egg-free. Leave out the two chopped eggs and proceed with the rest of the recipe. The salad will be a little less substantial, but the creamy dressing, potatoes, and crisp vegetables still make a complete deli-style side. If you want more crunch, add another ¼ cup (25 g) diced celery rather than adding extra mayonnaise.

Use dill pickles instead of sweet relish. Replace the sweet relish with ⅓ cup (50 g) finely chopped dill pickle, drained. This makes the salad sharper and less sweet. Taste before adding any extra vinegar, since dill pickles can bring plenty of acidity and salt on their own.

Make the flavor more mustard-forward. Increase the yellow mustard to 1½ tablespoons (22 ml), or replace 1 teaspoon of it with Dijon mustard. Dijon adds a deeper, slightly more pungent note; it is not a traditional requirement, just a useful option if you like a stronger mustard flavor. Add the extra mustard to the dressing before folding it through the potatoes.

Try a lighter, tangier dressing. Replace up to ¼ cup (60 ml) of the mayonnaise with plain Greek yogurt or sour cream. The result will taste tangier and less rich, and it may be a little looser after chilling. Avoid replacing all of the mayonnaise if you want the familiar creamy deli-style texture.

Storage and Reheating

Refrigerate the potato salad within 2 hours of making it, or within 1 hour if the room or outdoor temperature is above 90°F (32°C). Store it covered in an airtight container in the refrigerator at 40°F (4°C) or colder, and use it within 3 to 4 days. Because this recipe contains mayonnaise and cooked eggs, keep it chilled rather than leaving it on a counter or picnic table for an extended period. For serving outdoors, put out a small portion and replenish it from the refrigerator as needed.

This salad is meant to be served cold, so reheating is not recommended. Freezing is also a poor choice: mayonnaise dressing can separate after thawing, and the potatoes may become watery or grainy. If the salad has been left at room temperature for more than 2 hours, discard it rather than chilling it again. Do not rely on smell or appearance to judge whether food held too warm is safe.

Frequently Asked Questions

Can I make NY deli potato salad a day ahead?
Yes. Make it up to a day ahead, cover it, and refrigerate it promptly. The flavor has time to blend overnight. Before serving, stir gently and taste; potatoes can absorb dressing as they sit, so you can fold in a tablespoon or two of mayonnaise if the salad seems drier than you prefer.

Why did my potato salad turn mushy?
It usually means the potatoes cooked too long, the pieces were cut very small, or they were stirred roughly after becoming tender. Simmer rather than boil vigorously, start checking at 15 minutes, and drain as soon as a knife slips through the center. Russets naturally have softer edges, so use Yukon Gold or red potatoes if you want especially firm chunks.

Should I rinse the potatoes after boiling?
No. Drain them thoroughly, but do not rinse them. Rinsing cools the potatoes quickly and washes away some of the surface starch that helps the dressing cling. Letting them steam briefly in the warm pot removes excess water without diluting the dressing.

Can I use a different kind of vinegar?
Distilled white vinegar gives the clean, direct tang used in this version. Apple cider vinegar is a practical substitute and gives a rounder, slightly fruity flavor. Use the same amount, then taste after chilling before adding more, since vinegar strengths and personal preferences vary.

How do I keep the salad from tasting bland?
Season the cooking water, add vinegar while the potatoes are warm, and taste the chilled salad before serving. If it still needs something, add salt a small pinch at a time or mix in a teaspoon of vinegar. A little additional mustard can also sharpen the flavor, but add it gradually so it does not overwhelm the creamy dressing.
