Alison Roman's Potato Salad Recipe: Herb-Infused Mustard Vinaigrette Magic

Alison Roman's potato salad recipe transforms a classic side into something unexpectedly vibrant and sophisticated. The secret lies in her signature herb-infused mustard vinaigrette, where sharp Dijon and tangy vinegar create the perfect balance with fresh dill and chives.

I first tried this version after burning through three other recipes that fell flat—this one actually tastes like it belongs at a summer picnic, not just on a holiday table.

The technique is what sets it apart: waxy potatoes hold their shape beautifully when boiled just until tender, then tossed with a dressing that's both bright and complex. Roman's method calls for cooling the potatoes completely before mixing, which prevents that dreaded watery salad texture.

The herbs are finely chopped to distribute flavor evenly, while a touch of sweet corn adds unexpected depth that rounds out the acidity.

What you'll end up with is potato salad that's creamy without being heavy, tangy without being overpowering, and fresh enough to feel like a spring salad. The dressing clings to every potato, creating pockets of herby flavor with each bite.

This isn't your grandmother's mayo-heavy version—it's restaurant-quality with a fraction of the effort.

Perfect for summer gatherings, picnic baskets, or even a weeknight dinner when you want something that feels special. The recipe scales beautifully, so you can make it for a crowd or just enjoy the leftovers for lunch the next day. Here's how to make it exactly as Alison Roman would.

Ingredients for alison roman potato salad

These vibrant ingredients transform classic potato salad into something restaurant-worthy.

The potatoes are everything here—Yukon Golds hold their shape perfectly while soaking up the dressing. Grab them from the produce section (not the bagged potatoes—they're too starchy). Cut them into even 1-inch cubes so they cook uniformly. For the corn, fresh is ideal, but frozen works in a pinch—just thaw and drain well. The mustard and vinegar combo is the magic here: Maille Dijon if you want to splurge, but any good-quality Dijon will do. The herbs? Fresh dill and chives make all the difference—dried just won't cut it.

No fresh dill? Substitute with 1 tbsp dried, but trust me, it's not the same. Running low on red wine vinegar? Apple cider vinegar works too, though it'll have a slightly sweeter profile. The bacon is optional, but if you skip it, add another 0.25 cup of corn for texture. For the eggs, room temperature ones peel easier—just drop them in ice water for 10 minutes after boiling. The red bell pepper adds a nice crunch, but yellow or orange works just as well. And if you're feeling fancy, swap the olive oil for avocado oil for a higher smoke point.

This salad tastes even better the next day—make it ahead if you can. Store in an airtight container in the fridge for up to 4 days. The potatoes will soften slightly, but the flavors meld beautifully. For picnics, pack the dressing separately and toss just before serving to keep everything crisp. The bacon stays crunchy for about 2 days if stored properly, so add it last if you're prepping ahead. Leftovers? Perfect for lunch or a quick snack—just give it a little shake before eating.

Step-by-step instructions for Alison Roman's herb-infused potato salad

Here's how to create Alison Roman's signature potato salad—bright, herby, and perfectly balanced.

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 Diamond Crystal Kosher Salt and bring to a boil over high heat. Once boiling, reduce heat to medium-high and cook for 12-15 minutes until the potatoes are fork-tender but not falling apart.

Drain the potatoes immediately and let them steam-dry for 2 minutes in the pot. This step prevents a soggy salad later. While still warm, cut them into 1-inch cubes—I like to use a sharp chef's knife for clean, even pieces. Let them cool completely before assembling the salad, about 15 minutes. This cooling step ensures they don't turn to mush when mixed with the dressing.

In a medium bowl, whisk together the 0.5 cup Red Wine Vinegar, 0.25 cup Dijon Mustard, 1 tbsp Granulated Sugar, 0.5 tsp Freshly Ground Black Pepper, and 1.5 tsp Diamond Crystal Kosher Salt. This mixture should be smooth and well combined—no lumps of mustard should remain. Taste and adjust seasoning if needed; I usually find the vinegar needs a touch more salt at this stage.

With the whisk still in the bowl, slowly drizzle in the 0.5 cup Extra-Virgin Olive Oil while whisking continuously. The dressing should emulsify into a thick, creamy vinaigrette. If it separates, whisk more vigorously or add 1 tsp water to help bind it. Set aside—this dressing is the heart of the salad, so don't rush this step.

In a large mixing bowl, combine the cooled potato cubes, 1.5 cups Yellow Sweet Corn, 0.5 cup diced Red Bell Pepper, 0.5 cup finely chopped Fresh Dill, and 0.25 cup thinly sliced Fresh Chives. Gently fold everything together with a wooden spoon, being careful not to break the potatoes. Add the 4 whole Hard-Boiled Eggs, sliced into ¼-inch rounds, and the 0.5 cup Crispy Bacon if using.

Real talk: the bacon adds a smoky depth that elevates this salad from good to exceptional. If you're skipping it, don't worry—the herbs and mustard dressing still deliver big flavor. Pour the vinaigrette over the potato mixture and toss gently but thoroughly to coat every piece evenly. Taste and adjust seasoning if needed—you might need a pinch more salt or a splash of vinegar to balance the flavors.

Cover the bowl and refrigerate the potato salad for at least 2 hours, or preferably overnight. This chilling time allows all the flavors to meld together beautifully. The potatoes will absorb the dressing, the herbs will soften slightly, and the eggs will firm up just enough to hold their shape when served.

Before serving, give the salad a final toss to redistribute any settled ingredients. The texture should be creamy from the dressing, bright from the herbs, and perfectly balanced between the tender potatoes, sweet corn, and tangy vinaigrette. Serve chilled or at room temperature—it's equally delicious either way, but the flavors really sing when served cold.

Mustard Vinaigrette

The star of this potato salad is Alison Roman's signature mustard vinaigrette, where Dijon mustard and red wine vinegar create that perfect tangy backbone. I always use Maille Dijon for its smooth texture and bold flavor—it's worth the splurge if you're making this for company.

The key is whisking the mustard and vinegar together until completely smooth before slowly adding the olive oil. This prevents lumps and helps create that creamy, clingy texture that coats every potato perfectly. 🌶️

For extra depth, I like to add a pinch of freshly ground black pepper right at this stage—it brightens up the whole salad. If you're feeling adventurous, swap half the red wine vinegar for white wine vinegar to add complexity.

The sugar balances the acidity beautifully, so don't skip it. This dressing keeps well in the fridge for up to 5 days, so make extra for other salads or sandwiches.

Herb-Infused Finish

The fresh herbs are what truly elevate this salad from ordinary to extraordinary. Dill and chives add layers of flavor that you just can't get from dried herbs. I always chop them finely so they distribute evenly throughout the salad—no clumps of herb here!

For the dill, remove the tough stems and give the leaves a quick rinse before chopping. The chives should be thinly sliced on the bias for a delicate, almost fluffy texture. 🌿

Pro tip: If you're prepping ahead, store the herbs separately until just before serving to keep them vibrant. For an extra pop of color, I sometimes add a handful of sliced radishes or thinly sliced scallions right before serving.

The contrast with the creamy potatoes is amazing. And if you're feeling fancy, sprinkle with toasted pumpkin seeds for crunch and a nutty note.

Sweet Corn Addition

The sweet corn in this salad might seem unusual, but it's what makes the flavors sing. I prefer fresh corn cut right off the cob, but frozen works too—just make sure it's thawed and drained well. The natural sweetness balances the tangy mustard dressing beautifully.

For extra flavor, I sometimes add a pinch of smoked paprika to the corn while it's cooking, which pairs perfectly with the bacon if you're using it. 🌽

If you're making this in summer, try grilled corn instead—brush the kernels with olive oil, sprinkle with salt, and grill for 2-3 minutes until slightly charred. The smoky flavor adds another dimension to the salad.

For a vegan version, simply omit the eggs and bacon and add an extra 0.5 cup of corn to keep the texture satisfying.

Crispy Bacon

The crispy bacon is optional but adds a smoky depth that takes this salad to the next level. I like to use thick-cut bacon because it stays crispier longer. Cook it in a cold skillet over medium-low heat to render the fat slowly—this prevents it from burning.

Once crispy, chop it into small pieces so it distributes evenly. The fat from the bacon also helps balance the acidity in the dressing. 🥓

For a lighter option, try turkey bacon or even smoked paprika for a similar flavor without the fat. If you're making this ahead, add the bacon just before serving to keep it crispy.

The contrast between the creamy dressing and crispy bacon is what makes this salad so satisfying. And if you're feeling extra, drizzle with a little balsamic glaze before serving for a sweet-tangy finish.
