2nd Avenue Deli Potato Salad Recipe: Mayo-Rich, Mustard-Kissed Crowd-Pleaser

This 2nd Avenue Deli potato salad recipe delivers the creamy, tangy, mustard-kissed perfection that makes it a picnic and potluck staple. The secret lies in perfectly boiled potatoes, a rich mayo-mustard dressing, and just the right amount of crunch from celery and eggs—all balanced for that signature deli-style flavor.

I’ve recreated this crowd-pleaser after years of perfecting the texture and tang, ensuring every bite is creamy yet light, with a bright mustard bite that cuts through the richness.

The foundation starts with boiled potatoes—never undercooked, never mushy—tossed with a dressing that’s equal parts mayo and tangy mustard, plus a touch of sweet relish for balance. Celery adds fresh crunch, while hard-boiled eggs bring protein and richness, all bound together with a pinch of seasoning.

The result? A potato salad that’s foolproof, restaurant-quality at home, and impossible to resist.

What sets this apart is the textural contrast: tender potatoes, crisp celery, and creamy eggs in every forkful. The dressing is thick but not heavy, with just enough mustard to give it that classic deli tang.

Serve it at room temperature for the best flavor, or chill for a few hours to let the flavors meld even deeper.

For variations, swap mayo for vegan alternatives or add a dash of hot sauce for a spicy kick—but the traditional version is where the magic happens. Ready to make the best potato salad you’ve ever tasted? Let’s get started.

Ingredients for 2nd avenue deli potato salad

Potatoes, mayo, mustard—just three things that make this iconic deli salad perfect.

The potatoes are non-negotiable—Yukon Golds for their buttery texture. Most grocery stores carry them, but if you can’t find them, Russets work fine. Boil them until fork-tender, not mushy. I always grab a 5-pound bag from Whole Foods when I’m making this for a crowd—saves time and money. The mayo matters too—Duck brand has that perfect balance of richness, but Hellmann’s is a solid backup. The mustard? French’s classic yellow is the secret to that signature tang. No shortcuts here—store-bought relish just won’t cut it, so make your own or grab a jar of Heinz sweet pickle relish.

No mayo? Greek yogurt works in a pinch—just add a splash of lemon juice to keep it stable. Out of mustard? Dijon mustard at half the amount gives you a similar bite. Fresh celery is ideal, but dried celery flakes (one-third the amount) save time. The eggs should be ice-cold before chopping—keeps them from turning rubbery. No red onion? Green onions at double the amount add a milder crunch. The vinegar is key for boiling—white vinegar or apple cider vinegar both work, but don’t skip it. The sugar is subtle but balances the tang—brown sugar works too.

This salad tastes even better the next day—flavors meld perfectly after chilling. Keeps 4-5 days in the fridge, covered tightly. For picnics, I double the batch and pack it in glass jars—potatoes stay crisp, dressing stays creamy. The hard-boiled eggs? Store them in the fridge in their shells for up to 1 week before chopping. Leftovers? Toss them into a sandwich or wrap for lunch the next day.

Step-by-step instructions for 2nd avenue deli potato salad

Here’s how to make this iconic, creamy potato salad with a perfect balance of tangy mustard and sweet relish.

Place the 2.5 lb Yukon Gold Potatoes in a large pot and cover with cold water by about 2 inches. Add 1 tablespoon White Vinegar to help maintain their shape. Bring to a boil over high heat, then reduce to a gentle simmer for 12-15 minutes until the potatoes are fork-tender but still hold their shape when pierced.

Drain immediately and transfer to a large mixing bowl. Let them cool slightly for 5 minutes—this prevents the salad from becoming watery when mixed with the dressing. I like to shock them in ice water for 2 minutes if they’re still too hot, but this step is optional if you’re patient.

While the potatoes cool, chop the 2 whole Celery Stalks into ¼-inch dice and finely dice the ½ whole Red Onion. Place both in a medium bowl. In a separate bowl, whisk together 1 cup Mayonnaise, ½ cup Yellow Mustard, ¼ cup Sweet Pickle Relish, 1 teaspoon Sugar, 1½ teaspoons Salt, ½ teaspoon Black Pepper, and ¼ teaspoon Paprika until smooth and fully combined.

Here’s the thing—don’t skip the sugar. It balances the tangy mustard and enhances the sweetness of the relish, just like the deli version. The paprika adds a subtle smokiness that ties everything together. Taste the dressing now; you can adjust the salt or mustard if needed, but the proportions are already spot-on for classic flavor.

Add the chopped celery and onion to the dressing and stir until evenly coated. Then, gently fold in the cooled potatoes using a spatula or large spoon. Work carefully to avoid mashing the potatoes—you want them to stay intact for that classic deli texture. If the mixture seems too thick, add 1-2 tablespoons of ice water to loosen it slightly.

Next, fold in the 4 whole Large Eggs, chopped into ¼-inch pieces. The eggs add richness and a satisfying bite. Give everything one final stir to ensure the dressing is evenly distributed. Taste and adjust seasoning if needed—sometimes the potatoes need a touch more salt, especially if they were particularly starchy.

Cover the bowl with plastic wrap and refrigerate for at least 2 hours, or preferably overnight. This chilling time allows the flavors to meld and the potatoes to absorb the dressing fully. The longer it sits, the creamier and more cohesive the texture becomes—trust me, it’s worth the wait.

When ready to serve, give the salad one last gentle stir. It should be thick, creamy, and perfectly balanced between the tangy mustard, sweet relish, and rich mayonnaise. Serve it chilled, straight from the fridge, and watch it disappear at your next picnic or barbecue. The secret to this deli-style potato salad is patience—don’t rush the chilling step, and you’ll have a crowd-pleaser every time.

Wine and beer pairings for these flavors

Crisp White Wine

A dry Riesling from Germany or a Sauvignon Blanc from New Zealand is my go-to pairing for this potato salad. The bright acidity and citrus notes in these wines cut through the richness of the mayo while complementing the tangy mustard.

I love a Dr. Loosen Blue Slate Riesling—its crisp finish balances the salad’s creaminess perfectly. Serve it slightly chilled for the best experience. 🍷

Crisp Lager Beer

For beer lovers, a crisp American lager like Bud Light or Miller Lite works beautifully. The light, clean flavor doesn’t overpower the salad but refreshes your palate with each bite.

If you prefer something with a bit more character, try a Belgian Witbier like Hoegaarden—its coriander and citrus notes add a fun contrast to the mustard. 🍺

Sparkling Wine

If you want something special, a dry sparkling wine like Veuve Clicquot Yellow Label or Prosecco elevates the dish. The bubbles cleanse your palate, and the acidity enhances the mustard’s tang. I often serve this at picnics—it’s a crowd-pleaser that pairs surprisingly well with the creamy texture. 🥂

Light Red Option

For those who prefer red, a Pinot Noir with low tannins and bright fruit notes is ideal. Look for a Willamette Valley version—its red berry flavors won’t clash with the salad’s creamy richness. Avoid bold reds like Cabernet Sauvignon, as their tannins can overpower the dish. 🍇

Non-Alcoholic Pairings

Don’t drink alcohol? No problem! A sparkling apple cider like Martinelli’s or a ginger beer like Feani adds effervescence and a refreshing contrast. For something herbal, try sparkling mint lemonade—it’s light, crisp, and perfectly balanced. 🥤
