2nd Avenue Deli Potato Salad Recipe: Mayo-Free Mustard Vinaigrette Crunch

This 2nd Avenue Deli potato salad recipe delivers the iconic tangy crunch without a single drop of mayo—just like the original, but lighter and more vibrant. The secret lies in a bold mustard vinaigrette that cuts through the creamy texture of boiled potatoes, celery, and hard-boiled eggs, creating a salad that’s as satisfying as it is refreshing. I’ve perfected this version after years of testing, ensuring every bite stays true to the deli’s signature flavor while offering a modern twist.

The foundation of this recipe is high-quality potatoes boiled until tender but still holding their shape, then tossed with a tangy mustard dressing that balances sharpness and creaminess. Fresh celery and red onion add the signature crunch, while hard-boiled eggs bring richness without heaviness. What sets this apart is the mustard vinaigrette, which replaces mayo for a lighter, more flavorful bite—perfect for those who love the classic taste but want a healthier option.

By the time you’re done, you’ll have a potato salad that’s creamy yet crisp, tangy yet balanced, and packed with the bold flavors that made 2nd Avenue Deli famous. The texture is ideal—no soggy bits, just the perfect harmony of tender potatoes, crunchy vegetables, and a dressing that clings to every bite. This is the kind of salad that disappears faster than you can say "pass the bread."

Serve it at picnics, barbecues, or as a side for any meal—it’s versatile enough for any occasion but always delivers that nostalgic, deli-style taste. The best part? It keeps well in the fridge for up to 3 days, so you can make a big batch and enjoy it all week. Let’s get started!

Ingredients for 2nd avenue deli potato salad

High-quality potatoes, bold mustard, and fresh crunch—this iconic salad comes together in minutes.

The potatoes are everything. Yukon Golds are my go-to—their buttery texture holds up perfectly when boiled. Trader Joe's or any grocery store has them year-round, but if you're feeling fancy, grab them at a farmers market. Don't skip the boiling water salt—it seasons the potatoes right from the start. The red onion and celery should be fresh, with crisp stalks that snap when bent. Look for vibrant color—no wilted or yellowed leaves. Pro tip: Soak the celery in ice water for 10 minutes before slicing to keep it extra crisp.

No Dijon mustard? Extra yellow mustard plus a pinch of smoked paprika works in a pinch. The apple cider vinegar is non-negotiable for that classic tang—subbing with white vinegar changes the whole vibe. For a mayo-free version, the olive oil plus extra mustard combo gives the perfect creamy texture. Fresh dill is ideal, but dried dill at one-third the amount gets you close. Want more crunch? Add 1/4 cup chopped pickles or 1/2 cup diced bell pepper. The salad keeps its crunch best if you toss it with the dressing right before serving.

This salad tastes even better the next day—honestly, the flavors meld perfectly after 24 hours. Store it in an airtight container in the fridge for up to 3 days. The dressing separates? Just whisk it back together before serving. For picnics, I like to pack the potatoes and veggies separately, then toss with dressing at the last minute to keep everything crisp. The eggs? Peel them right before adding to the salad so they don't get rubbery.

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

This creamy, tangy potato salad delivers the iconic deli experience with a mayo-free twist.

Place the 2.5 lb Yukon Gold Potatoes in a large pot and cover with cold water by about 2 inches. Add 1.5 tsp Salt and bring to a rolling boil over high heat. Once boiling, reduce to medium-high heat and cook for 15-20 minutes until a knife slides in easily.

Drain immediately and transfer to a large mixing bowl. Let them cool completely—about 15 minutes—before handling. Cool potatoes prevent the salad from turning mushy. While they cool, chop the 6 whole Large Eggs into small pieces and set aside.

In a medium bowl, whisk together the 0.5 cup Yellow Mustard, 2 tbsp Dijon Mustard, 0.25 cup Apple Cider Vinegar, 0.5 cup Extra-Virgin Olive Oil, 1 tbsp Granulated Sugar, 1 tsp Black Pepper, and 0.25 cup Fresh Dill. This is the heart of the flavor—don't rush the whisking. The mixture should be smooth and slightly thick.

Taste and adjust seasoning if needed. I like to add a pinch more salt or sugar if the mustard wasn't particularly bold. This tangy, creamy dressing replaces mayo while keeping the signature deli taste.

Once the potatoes are cool enough to handle, gently fold in the chopped eggs, thinly sliced Red Onion, and thinly sliced Celery Stalks. Add the mustard vinaigrette and mix thoroughly. For extra creaminess, fold in the 0.25 cup Mayonnaise if using. The salad should be moist but not soupy—if it's too thick, add 1-2 tablespoons of water to loosen.

Here's the thing—don't overmix. Just until everything is evenly distributed. Overworking the potatoes will break them down and make the salad gummy. The texture should be rustic, with whole potato chunks and visible crunchy vegetables.

Cover the bowl and refrigerate for at least 4 hours, preferably overnight. This chilling time lets the flavors meld and the potatoes absorb the dressing. The longer it sits, the better it tastes. I promise you won't regret waiting.

Before serving, give it one final taste and adjust seasoning if needed. The salad should be bright, tangy, and perfectly balanced between creamy and crunchy. Serve chilled with crusty bread or alongside grilled meats for that classic deli experience.

Dietary considerations for 2nd avenue deli potato salad

Gluten-Free Adaptations

This potato salad is naturally gluten-free, thanks to its mustard vinaigrette base and fresh ingredients. The key is ensuring your mustards are certified gluten-free—French’s Classic Yellow Mustard and Maille Dijon Mustard are both safe choices. I always double-check labels since some brands add gluten-containing additives. For extra security, use gluten-free apple cider vinegar and verify all spices (like black pepper) are processed in gluten-free facilities. 🌱

Dairy-Free Options

Skip the optional mayonnaise entirely for a dairy-free version, or substitute with vegan mayo like Hellmann’s Vegan or Just Mayo. The mustard vinaigrette already provides enough creaminess, so no additional adjustments are needed. If you're avoiding eggs, replace the hard-boiled eggs with chopped avocado (½ cup) or tofu cubes (½ cup, marinated in lemon juice) for protein and texture. The salad remains vibrant and satisfying!

Lower-Carb Modifications

For a lower-carb version, swap half the Yukon Gold Potatoes (about 1.25 lb) for cauliflower florets (about 2 cups, steamed until tender). The cauliflower adds volume while reducing carbs—just be sure to drain it well to avoid excess moisture. Keep the rest of the recipe the same, including the mustard vinaigrette. This tweak cuts carbs by roughly 50%, but the salad still delivers that signature deli crunch and tang.

Allergen-Friendly Swaps

If you're avoiding mustard, replace the yellow and Dijon mustard with a mix of 2 tbsp apple cider vinegar, 2 tbsp olive oil, and 1 tbsp tahini for creaminess. For a nut-free option, omit the tahini and add 1 tbsp lemon juice instead. If celery is a concern, substitute with diced bell peppers (½ cup) or jicama (½ cup, julienned) for crunch. Always check ingredient labels—some vinegars and spices may contain hidden allergens.

Nut-Free and Egg-Free

This recipe is already nut-free, but if you're avoiding eggs, try chickpea salad as a protein swap. Use 1 cup mashed chickpeas (rinsed well) mixed with 1 tbsp lemon juice and 1 tsp Dijon mustard to mimic the texture. For extra richness, stir in 1 tbsp olive oil. The salad stays hearty and flavorful while accommodating dietary restrictions. Always taste as you go—adjust seasoning to balance the new ingredients. ✨
