17th Street Potato Salad Recipe: Vinegar-Kissed Creaminess Without Mayo Overload

This 17th Street potato salad recipe delivers the signature tangy, creamy texture that makes it a Southern classic—without drowning in mayo. The secret lies in balancing vinegar and buttermilk for that signature bite, while still keeping it rich and satisfying.

I’ve perfected this version over years of summer cookouts, where it’s always the first dish to disappear. What sets this apart is the two-stage dressing—first blending vinegar and mustard for sharpness, then lightening with buttermilk to create a velvety, not greasy, finish.

The potatoes stay firm and crisp, not mushy, thanks to a quick ice bath after boiling. Hard-boiled eggs add protein and texture, while fresh herbs keep it bright.

By the time you serve this, you’ll have a potato salad with perfect balance—tangy enough to cut through rich barbecue, creamy enough to satisfy, and crisp enough to hold up all day. The flavor develops as it chills, so making it ahead is a must for the best results.

Serve it at picnics, potlucks, or alongside grilled meats—it’s the kind of dish that turns a simple meal into a showstopper. Here’s how to make it.

Ingredients for 17th street potato salad

Pantry staples plus a few fresh touches—this Southern classic comes together in minutes.

The potatoes are non-negotiable—Yukon Golds hold their shape better than russets, and cutting them into even 1-inch cubes ensures perfect cooking. Trader Joe’s sells them pre-washed, which saves time, but any waxy potato works. For the vinegar, distilled white gives the cleanest tang—apple cider vinegar adds complexity but might overpower if you’re not careful. The buttermilk? Full-fat only—low-fat won’t give that signature creamy texture. I always grab mine from Whole Foods when I can, but the regular grocery store kind works fine too.

No Dijon mustard? Yellow mustard thinned with a little vinegar gets you close. Fresh dill is ideal, but dried dill at one-third the amount works in a pinch. The celery can be prepped ahead—just store it in a sealed container in the fridge for up to 3 days. Red onion is key for brightness, but if you’re sensitive to bite, soak the diced pieces in cold water for 10 minutes before draining. The eggs should be ice-cold when chopped—this keeps them from getting rubbery. For extra richness, swap half the mayo for Greek yogurt.

This salad tastes even better the next day—make it ahead and refrigerate for at least 4 hours before serving. Store leftovers in an airtight container for up to 5 days, though the texture starts to soften after day 3. I like to portion it into individual containers so it’s ready for picnics or potlucks. For a crispier finish, add a pinch of salt and a few ice cubes just before serving—trust me on this.

Step-by-step instructions for 17th Street potato salad

Here’s how to make this tangy, creamy potato salad with perfect texture and balance.

Place the 2.5 lb Yukon Gold potatoes into a large pot and cover with cold water by about 1 inch. Add the 1.5 tsp kosher salt and bring to a rolling boil over high heat. Once boiling, reduce heat to medium and cook for 12-15 minutes until a knife slides in easily with just slight resistance.

Drain the potatoes immediately and transfer them to a large mixing bowl. Let them steam-dry for 2 minutes to remove excess moisture—this prevents a watery salad. While they’re still warm, gently press each potato cube with a fork to create slight indentations that will help the dressing cling better. I like to do this while they’re still warm so they don’t get mushy.

In a medium bowl, whisk together the 0.5 cup buttermilk, 0.5 cup distilled white vinegar, 2 tbsp Dijon mustard, and 0.25 cup mayonnaise until completely smooth. The vinegar adds that signature tang you know from 17th Street, while the mustard provides depth. Let this mixture sit for 5 minutes to allow the flavors to meld together slightly.

Add the 0.25 cup red onion and 2 tbsp fresh chives to the dressing and stir well. The raw onion adds a bright crunch that balances the richness of the potatoes. Give it a taste at this point—you want the dressing to be tangy but not overpowering. If it needs more acidity, add 1 teaspoon more of the vinegar.

Add the warm potatoes to the dressing mixture and gently fold everything together using a large spoon. You want to coat each potato cube evenly without mashing them. The potatoes should absorb the dressing quickly—if they seem dry after mixing, add 1-2 tablespoons of cold water to help distribute the dressing.

Transfer the potato salad to a large serving bowl and place it in the refrigerator for at least 2 hours, or preferably overnight. This chilling time is crucial—it allows all the flavors to meld together and the potatoes to fully absorb the dressing. The longer it chills, the better the texture becomes.

Just before serving, chop the 4 hard-boiled large eggs into small pieces and stir them into the potato salad. The eggs add a wonderful contrast in texture and richness. Add the 2 whole celery stalks (finely diced) and 0.25 cup fresh dill, gently folding everything together one last time to distribute the herbs evenly.

Taste and adjust seasoning with additional salt or pepper if needed. The salad should have a perfect balance of tangy, creamy, and fresh flavors. For presentation, sprinkle with the remaining 2 tbsp fresh chives and serve immediately. This potato salad tastes even better the next day as the flavors continue to develop.

Health benefits of 17th street potato salad

Protein Powerhouse

This potato salad packs a serious protein punch with 4 hard-boiled eggs and the creamy base of buttermilk and mayo. Each serving delivers about 12 grams of protein, making it a satisfying side for meat-heavy meals.

The eggs add texture and richness while keeping the dish balanced. I always make sure to use ice-cold eggs when chopping to maintain that perfect firm-yet-tender bite. 🥚

Low-Fat Option

For a lighter version, swap half the mayo for Greek yogurt—it cuts calories while keeping that creamy texture. The buttermilk still provides richness, but you’ll reduce fat by about 30% per serving.

I like using non-fat Greek yogurt from Fage for the best consistency. This version still tastes indulgent but fits better into a balanced meal plan.

Fiber Boost

The celery and red onion add fiber without overpowering the dish. Together, they contribute about 2 grams of fiber per serving, helping digestion while adding fresh crunch.

For extra fiber, I sometimes add ¼ cup diced green bell pepper—it holds up well during chilling and adds a subtle sweetness that pairs perfectly with the tangy dressing. 🧅

Vitamin C Kick

The red onion provides a surprising amount of vitamin C—about 10% of your daily needs per serving. This vitamin helps boost immunity and keeps your skin healthy. The fresh dill also contributes antioxidants, making this potato salad more than just a creamy side dish.

I always use red onion instead of yellow because it has slightly more vitamin C and adds a beautiful color contrast.

Healthy Fats

The buttermilk and mayo provide healthy fats that your body needs. These fats help absorb fat-soluble vitamins like A, D, E, and K from other foods you eat.

The full-fat buttermilk is key—it creates that signature creamy texture while delivering beneficial fats. I recommend using Whole Foods 365 brand for the best quality and flavor. 🥛

Antioxidant Rich

The fresh dill and chives in this potato salad are packed with antioxidants that fight inflammation. Dill contains compounds like carvone and limonene, while chives provide quercetin—a powerful antioxidant.

Together, they help protect your cells and keep your body running smoothly. I always add these herbs right before serving to preserve their freshness and vibrant flavors. ✨
